Genomic Selection: Towards Meeting Challenge of Food Security
Hamdy
Abdel-Shafy
Breeding is a powerful science and remains a core component of most agriculture production. Although traditional selection has proven to be a successful approach for improving animal and plant production in the last decades, several studies have reported a worrying shortage between the current rates of production and expected global future demands for food. These challenges, coupled with a constant loss of suitable land for agricultural production, needs to implement new breeding strategies to significantly increase the genetic gain and meet the future requirements. Recent advances in genotyping capacity with affordable costs have allowed selection based on genomic information. These technologies would reshape the breeding programs, accelerate the genetic gain and maximize the productivity per unit. Although this concept was suggested many decades ago, the applications of marker-assisted selection were limited due to the low number of genotyped markers and low number of identified QTL. In contrast, genomic selection (GS) utilizes the dense genetic markers across the whole genome to predict the effect of all QTL that are assumed to be in linkage disequilibrium with at least one genetic marker. Nowadays, GS is widely implemented in several species for breeding purposes and attracted attention for human disease risk predictions. It has been proven for many traits to double the rate of the genetic gain and reduce the generation interval, which would efficiently contribute to more food security. Here, we introduce the general concept of GS, and briefly describe the GS models along with the recent progress in some farm animal species.

In poultry, selection programs through quantitative genetics are time consuming in case of lowly heritable traits. Several genes that to be used in selection are regarded as candidate genes that affecting economic traits in poultry and these candidate genes have successful approaches in identifying several DNA markers associated with production and reproductive traits. Candidate genes are one of the primary methods to determine the specific genes related to the economic traits and molecular genetics techniques can be used to identify these genes or their chromosomal regions in terms of Quantitative Trait Loci (QTL) that affect these traits. Using biotechnology techniques are the best way to achieve this fast genetic improvement. This approach has enabled opportunities to enhance genetic improvement programs in poultry by direct selection on genes or genomic regions that affect economic traits through marker-assisted selection (MAS) and gene introgression. Mapping of quantitative trait loci (QTL) was the perfect approach to identify genes related to complex traits at genome-wide level. Recently, genome wide association study (GWAS) was used to identify the casual genes affecting economic traits in poultry using sequences variations mainly single nucleotide polymorphism (SNP). Many genes for growth and egg production were identified in poultry using GWAS method. The objectives of this reviewed article are: 1) To apply a fine chromosomal mapping for localizing the QTL affecting economic traits in the F2 population using specific microsatellite markers or SNP's in chickens and possibly identify candidate genes and causative mutations associated with the economic traits, 2) Determining the molecular markers to be used for evaluating the genetic variability among poultry breeds, 3) Reporting and characterizing the candidate genes to be used in genetic improvement programs, 4) Detecting the molecular associations between candidate genes and growth, feeding and egg traits and disease resistance responses, 5) Determining the SNP genotypes and their associations with growth and feeding performances, egg traits and disease resistance responses, 6) Defining the genetic model for detecting the molecular associations between SNP genotypes of candidate gene and economic traits, 7) Performing genome wide association study (GWAS) in order to detect potential causative mutations and genomic regions affecting productive and reproductive traits in chickens, 8) Applying genomic selection program based on the estimated Genomic Breeding Values (GBV), and 9) Suggesting a genetic improvement program to improve the Egyptian chickens breeds and strains using molecular approaches.

Water Saving Strategies in Mediterranean Areas
Maria
Isabel
Mediterranean climate is associated with summer water scarcity and, consequently, with a general susceptibility to erosion, degradation, and desertification. Thin soils, with low water storage capacity, develop in slopes where all main factors for erosion can at its worst. The need for wise irrigation is crucial for human activities. Plant adaptation includes stomatal closure as a strategy to reduce water use improving plant survival, while reducing photosynthesis and control of leaf temperature. Other strategies at leaf level include reducing radiation interception and increasing sensible heat diffusion, for instance by developing small leaf size, high leaf reflectance and adapted positions towards sunlight. Another order of survival strategies to cope with summer water scarcity concerns the increase of water uptake at root level and hydraulic lift or water redistribution. Finally, irrigation efficiency and evapotranspiration efficiency also should be optimised. Several experiments were performed on olive orchards under the harsh summer conditions of South East Portugal. The results were consistent in several aspects related to water uptake: colonization of the inter-row space, qualitative and quantitative importance of hydraulic redistribution and water balance estimates from soil water content versus plant water use measured by a micrometeorological technique. In orchards under deficit irrigation, analysed in same study, water use was also quantified and parameters of stress coefficients functions were critically analysed.

Manipulation of Bio-nanotechnology in Agri-Sector for Pest Control with Special Emphasis to Nematode Problems in Egypt
SANAA
HAROON
With the extravagant increase in the population and the increasing need for food, space and desert development, especially for agricultural expansion, has become a strategic goal and the focus of the economic and social policies of Egypt. The coming decades will witness accelerated rates of development in desert agriculture, not only through expanding beyond the green boundaries of the delta and the Nile valley , but also by crossing to remote areas in Sinai , southern Egypt. Soil nematode infecting plants are one of the most destructive parasites worldwide and cause crop damages with wide host rang. Attacking plant root system and feed on the plant nutrients causing lose in the crop yield and even death of the plants by developing galls and necrosis in the root system losing the ability of absorb the nutrients, water and die. The current major issue concerning nematode damage to plants is the lack of effective chemical treatment methods. The public concern over the chemical Nematicides is not only their toxicity for health and environmental risks but also their loss of efficiency after prolonged use. Several control strategies alternative to chemical control that develops recently is production of natural Bio-Nano Nematicides as (green chemical) which act as inhibitors against nematodes population in soil. The Advantages of using bionano Nematicides, it's safe organic compound extracted from the plant, It has no residual effect, It gives high ability to reach within the roots to combat nematodes in their phases, and the ability of the compound to rapidly spread in irrigation water which also gives the strength to spread and stay in the soil for a long time. The nematicides caused direct death to nematodes after few minutes when exposed to low concentrations, also has a repellent effect due to the presence of nanoparticles around the roots, the penetration of nanoparticles inside the root causes the inability of nematodes to form the nourishing cells and are therefore destroyed. It was also found out that there are more than 800 products as fertilizers in the world with their effective as nanomaterials, it is used for sprinkling on the vegetable, which will benefit the plant faster by Increasing photodynamic activity also increasing leaf content of chlorophyll. Also that product Increase crop capacity to withstand different stress conditions, Absorption speed, and Only 1 kg of nanophosphate fertilizer is required to replace 150 to 200 kg of superphosphate fertilizer in citrus farms. For example, Nanomaterials help protect the environment and human health, Increases farm profitability due to reduced fertilizer and spraying costs. Finally Advantage of using Bio-nanotechnology application in agriculture is seriously contributes effectively to increase the productivity of crops, Increase the quality of fruits, Increase their competitiveness by reducing the residues of fertilizers, Preserves the soil and reduces the contamination of groundwater with the residues of different fertilizers, Economically reflected on the economic yield of the farmer through the reduction of expenses, and thus increase the profitability of different crops, and increase export opportunities through increased product competitiveness .

Osama
El-Garhy
The present study was conducted to evaluate the effect of stocking density, dietary supplementation of probiotic and Vitamin D3 on carcass yield and blood biochemistry of broiler chickens. A total number of 360 unsexed broiler chicks (Evian), one-day old, nearly similar in live body weight were used in this study. Chicks were randomly divided into equal 12 treatments in a 2X3X2 factorial arrangement experiment. Birds were allocated in two main experimental groups (each of 180 birds), the first main group kept under normal stocking density (LSD) with 10 birds /m2 and the second main group kept under high stocking density (HSD) with16 birds/m2. Each main group was divided into three groups (each of 60 birds) fed on diets supplemented with probiotic at a levels of 0, 1 and 2 g/kg diet, respectively. Each group divided into two sub-group (each of 30 birds) and supplemented with fed vit.-D3 at a level of 250 and 500 IU/kg diet, respectively. Results obtained showed that raised broiler chickens under LSD had significantly improved absolute and relative carcass, giblets and total edible weight Moreover, it has significantly increased plasma total protein, albumin (A), globulin (G), cholesterol, triglyceride and it has decreased plasma transaminase enzymes of AST and ALT, compared with those rose under HSD. Broiler chicks fed on diet supplemented with probiotic at level of 2 g/ kg diet showed higher plasma total protein, albumin and A/G ratio, cholesterol and triglycerides than those fed on the other levels of probiotic supplementations. While, it has recorded lowest plasma AST and ALT levels, compared with the other experimental groups. Feeding broiler chickens on high level of Vit.-D3 (500 IU/ Kg diet) has significantly increased plasma protein fractions and decreased plasma AST and ALT levels, compared with those fed diet supplemented with low level of Vit.-D3 (250 IU/Kg) that caused significant decreased plasma cholesterol and triglycerides. Finally, it could be recommended to apply LSD (10 birds/ m2), high level of Vit.-D3 (500 IU/ Kg) and probiotic at a level of 2 g/ kg diet to improve carcass yield and blood biochemistry of broiler chickens.

The present study was conducted to evaluate the effect oforganic acids (citric, lactic and propionic) and their mixtures on carcass traits and blood biochemistry of broiler chickens. A total number of 480 broiler chicks (Ross) one-day old, nearly similar in live body weight were used in this study. Chicks were randomly divided into eight experiment groups each of 60 chicks in3 replicates of birds. Chicks of the first group fed starter and grower basal diets without any supplementation and considered as a control group, the second, third and fourth groups were fed starter and grower basal diets with 5g/kg of either citric, propionic or lactic acids, respectively. While, the fifth group fed starter and grower basal diets with 5g/kg citric acid and 5g/kg propionic acid. The 6th and 7th groups fed starter and grower basal diets supplemented with 5g/kg citric and 5g/kg lactic acids, 5g/kg propionic and 5g/kg lactic .The 8th group fed starter and grower basal diets supplemented with 5g/kg of each of Citric+ Propionic+ Lactic. Results obtained showed that chicks fed diet supplemented with citric and lactic acid, respectively had significantly increased the absolute and relative weights of carcass and total edible parts, the highest averages of plasma total protein , globulin and decreased plasma AST and ALT. Chicks fed on diet supplemented with the mixtures of Citric + Lactic + Propionic acid showed the highest averages of absolute and relative weights of carcass and total edible parts, plasma total protein, globulin and lowest plasma creatinine compared with the other treatments and control group. While chicks received diet supplemented with citric acid showed the highest value of plasma albumin and relative economical efficiency (REE). Generally, it is clearly observed from this study that using organics and their mixtures had improved the carcass yield, blood biochemistry and economical efficiency of broiler chickens compared with control. Citric acid at a level of 5g/kg diet seemed to be adequate to achieve the favorable results and is being recommended from the economic point of view.

M. El-Sharkawy
This study was aimed to investigate the effect of dietary supplementation of Pedicoccus acidilactici as probiotic (P), chicory as phytogenic (C) and their interactions between them (P x C) on productive performance and immune response of Inshas laying hens. A total number of 720 chickens, 26 weeks old with nearly similar initial average weight were used in this study. Hens were randomly distributed into twelve experimental groups each of 60 birds. A factorial arrangement design (3x4) with three levels of probiotic (0, 0.5 and 0.1 g/kg diet) and four levels of chicory leaves powder (0, 5, 10 and 20 g/kg diet) and their interaction were tested for 24 weeks. Results obtained showed highly significant variation (p < 0.01) in averages of feed conversion ratio (FCR), egg production rate (EPR) and egg mass at the most periods of the experiment and all over the experimental period due to all treatments applied, Insignificant variation were found in average body weight, feed intake and egg weight due to dietary levels of probiotic and chicory all over the experimental period, while the interaction between them showed highly significant variation (p < 0.01) in body weight and egg weight only. The best FCR (4.67. 4.64 and 4.03 g feed/g egg), EPR (53.35, 53.29 and 62.16 % hen/day) and egg mass (26.19, 26.22 and 30.10 g/hen/day) were found in birds fed diets supplemented with 1.0 g probiotic, 5 g chicory / kg diet and the interaction between (P2 x C1), respectively. Significant improvement (p < 0.05) in immune response toward antibody titers of Newcastle (ND) and Influenza (H9N2) due to dietary probiotic only. The highest values of relative economical efficiency were found 129.20, 281.39 and 270.14% were listed for diets containing 1.0 g probiotic, 5 g chicory /Kg diet and their interactions between the same levels, receptively. It could be recommended to use probiotic at a level of 1.0 g, chicory at level of 5 g /Kg diet and their interactions (1.0 g probiotic x 5 g chicory/Kg diet) to improve the productive performance, immune response and economical efficiency of Inshas laying hens.

Gene Expression Profile of Oocytes Using Microarray and Single Nucleotide Polymorphisms of Stat3 and Odc1 Genes in Sperms Linked With Their Quality in Holstein-Friesian
Nasser
Ghanem
Identification of molecular fingerprints of gametes quality could be used as a foundation for finding markers associated with fertility of dairy cattle. Therefore, the current investigation aimed to identify differential gene expression profile in oocytes collected from cyclic healthy heifers (n = 16) of Holstein breed with estimated breeding value of fertility. The animals were slaughtered at day 0 or day 12 of the oestrous cycle. The recovered oocytes from high-fertile animals (H-EBV-F >100; n=8) were compared with low-fertile group (L-EBV-F <100; n=8) using cDNA microarray. Additionally, SNPs were analysed for two candidate genes (STAT3 and ODC1) in relation with sperm quality traits. The results of this study clearly showed link of candidate genes with fertility and progesterone profile during oestrous cycle. For example, gene expression profile of STAT3 was increased in oocytes collected from H-EBV-F animals at day 0 and 12 of oestrous cycle. While ODC1 gene was up-regulated at day 12 and down-regulated at day 0 in H-EBV-F compared to L-EBV-F oocytes. Moreover, association study showed that SNP polymorphisms of STAT3 and ODC1 were linked (p < 0.05) with sperm quality traits. Therefore, it could be concluded that ODC1 and STAT3 could be considered candidate genes that are connected with Holstein cows fertility genetic merit of the associated with semen quality of sires.

Romysa
Gad-Elkareem
Effect ofheat shock and co-culture of monolayer granulosa cells (GCs) on in vitroembryo developmental competence in Egyptian buffalo was the aim of the present study.Cumulus oocytes complexes (COCs) were collected from ovaries (n= 448) of cyclicslaughtered buffalo cows. Good quality immature oocytes (n= 1512) were subjected to in vitro maturation and fertilization. Post 18-22 h of fertilization, presumptive embryos were randomly assigned into four groups: (G1) No heat shock (38.5OC), (G2) Heat shock (40.5°C) and (G3) Co-culture with GCs monolayer and heat shock or (G4) Co-culture with GCs monolayer and no heat shock. Heat-shockedembryos were exposed to temperature of40.5°Cfor the first two hours of culture before exposing to 38.5°C afterward up to the end of culture perio d (8 days). The data were analyzed by General LinearUnivariate model using SPSS.
Oocyte expansionrate was 90.8±1.1%. This percentage is higher than nuclear maturation rate (oocytes at Telophase and Metaphase II) as detected byaceto-orcein staining by about 17%. Cleavage rate as recorded at day 3 post fertilization (day 0) was higher (p≤0.05) for G1 and G4 (71.1±10.5% and 70.5±7.9 with GCs, respectively).On the other hand, cleavage rate was dramatically decreased (P ≤0.05) for embryos of G2 (43.7±7.0%) compared with that of G3 (80.2±7.0%). In addition, embryos of G3showed approximately the same rate ofdeveloped embryos(Morula and blastocyst stages at day 8 of culture) as of G1 (50.9±5.3 and51.7±7.9%, respectively). In conclusion, using co-culture of GCs as a monolayer enhances cleavage rate and subsequent embryo development of buffalo embryos under heat stress condition.

Chicken Cytokines Functions as Bioreactors
Akrum
Hamdy
Cytokines are proteins excreted by cells that play an important role in the activation and regulation of other cells and tissues during inflammation and immune responses. They act as humeral regulators which modulate the functions of individual cells. Unlike hormones, cytokines are produced by cells which are not organized in specific glands which act to affect biological cases such as inflammations.
The biological activities of cytokines are mediated by specific membrane receptors which can be expressed on substantially all cell types. The mechanism by which receptor occupation by cytokines results in the generation of a signal through the receptor is not completely understood. But it is frequently possible to observe the order of cytokine actions with some early cytokines preactivating cells so that they can then respond to later acting cytokines.
All cytokines act through receptors on the surface of the target cells, which may lead to the activation or down regulation of the cell's activity. The main function of cytokines is in the activation and regulation of the cells of immune system. Cytokines are produced by variety of cell types, depending on the cell's function. For instance, epithelial cells may produce cytokines involved in the generation of inflammation, the so-called proinflammatory cytokines such as interleukin-6 (IL-6) or IL-8, whereas macrophages may produce both proinflammatory cytokines and cytokines involved in the activation and regulation of T helper lymphocytes (Th) in the development of an adaptive immune response. Cytokines have been classified into a number of groups based on their activity and the cells they are produced by or act upon. These groups include interleukins (IL), interferons (IFN), tumour necrosis factors (TNF), transforming growth factors (TGF), migratory inhibitory factors and the smaller chemokines. It is also possible to broadly categorise cytokines on their activity and this may be more beneficial in understanding the nature of their general activity. The use of molecular techniques is enabling the role of cytokines in the pathogenesis of diseases. This will lead to further understanding of the role the immune system, and in particular cytokines.
In this review article the types and functions of chicken cytokines will be accurately
displayed.

Recently, many countries tend to prevent the application of antibiotics for their side effects on both animal and human. Nowadays, growth promoters from herbal sources (phytogenic extracts) are used very commonly. Herbs such as Turmeric (Curcuma longa), ginger (Zingiber officinale), fenugreek (Trigonella foenum-graecum L.) and other herbs are phytogenic additives, possible alternatives, reported in poultry production which include a group of natural feed additives; derived from herbs, spices or other plants or their extracts in the form of essential oils. The optimum antioxidant activity of some herbs such as turmeric tends to stimulate protein synthesis by enzymatic system. Furthermore, herbs could control and limit the growth and colonization of numerous pathogenic and non-pathogenic species of bacteria in the rabbit's gut resulting in balanced gut microbial ecosystem that leads to better feed utilization reflected by live body weight and weight gain. Citrus have over 60 flavonoids and these compounds can be digested in the small intestine therefore, the level of these flavonoids can significantly increase in blood serum. Flavonoids have antioxidant, anti-inflammatory, antibacterial and immune-stimulating effects. The aim of this review was to evaluate the effect of growth promoters as feed supplementation in rabbit diets on some productive performances.

Alleviating the Harmful Effects of New Valley Summer on Growth Performance and Health Status of Japanese Quail by 1. Feeding time
Farghly
M. F., A.
A total number of one hundred and fifty unsexed one-day old chicks of Japanese quail were used to study the effect of feeding time on the growth performance of birds under subtropical prevailing environmental conditions in New Valley. All chicks were housed in batteries in five equal groups (3 replicates of 10 birds each). The birds of first group were full-fed ad libitum and were considered the control (C). While the second group (T1) was fed 75% of diet at morning and 25% of diet at afternoon; the third group (T2) was fed 50% of diet at morning and 50% of diet at afternoon; the fourth group (T3) was fed 25% of diet at morning and 75% of diet at afternoon; the fifth group (T4) was fed 0% of diet at morning and 100% of diet at afternoon. All experimental birds were supplied with clean water all the time. The obtained results indicated that change of feeding time affected body weight, feed conversion, most blood parameters, body temperature, viability rate and tonic immobility in Japanese quail. However, insignificant differences of plumage conditions and some carcass traits were observed among all experimental groups. Therefore, it could be recommended that feeding time (25% of diet at morning and 75% of diet at afternoon) during summer season could be applied successfully by the farm managers to have a better growth performance without any significant negative effects on production process.

Alleviating Heat Stress during Summer Season on Performance of Growing Rabbits by Using Feed Withdrawal
M.
Farghly
This study was designed to alleviate theheat stress during summer season on growth performance of New Zealand white rabbits by using feed withdrawal; Animals were reared in batteries anddivided into four comparable groups (32 growing weanedrabbits in each). The four treatments were as follows: Control group (C) (rabbits were fed continuously for 24 hrs), T1 (feed was removed from 9 am to 12 am), T2 (feed was removed from 12.00 am to 3.00 pm) and T3 (feed was removed from 9.00 am to 3.00 pm).Theresults revealed that, daily body weight, feed conversion and some blood constitutes of growing NZW rabbits affected significantly. Feed withdrawal improved significantly body weight gain, feed conversion, dressed carcass and health status and decreased significantly whole fat percentage and rectal temperature. Rabbits of T2 and T3 groups showed the lowest (P<0.05) values of A:Gratio and N/L ratio when compared with their counterparts. Non-significant differences were found in the other morbidity and carcass characteristics due to feed withdrawal. From these results, it could be concluded, that feed withdrawal in growing rabbits during 12.00 am to 3.00 pm had beneficial impacts on performance and improved health status in the hot summer.

Impact of Some Managerial Factors on Carcass and Meat Quality of Japanese Quail Farghly M. F. A. and H. Y. El-Hammady
M.
Farghly
The present study aimed to investigate the impact of some managerial factors (stock density, litter and floor types) on the carcass traits and meat quality of Japanese quail birds. All experimental birds were randomly distributed to 2 X 4 factorial design, which contains two stoking densities (250 or 400 cm2 / bird) and four litter and floor types; wheat straw group served as control, wire net group, plastic group and wooden slatted floors. The obtained results confirmed that stock density, litter and floor groups had significant (P≤0.05) higher dressed carcass, liver percentages, carcass lengths, fatness, protein, Ca and Fe percentages of meat content. Likewise, significant effects were found on sensory attributes (tenderness and juiciness), texture and pH of meat. However, no significant differences in percentages of heart, kidney, dissectible fat, Lean:bone ratio, moisture, ether extract, ash, P, aroma, taste, flavor and water holding capacity (WHC) were found among all groups. Taking in consideration these advantages it could be concluded that the use of plastic group and wooden slatted floors with stock density (400 cm2 / bird) is highly recommend for managing Japanese quail birds.

M.
Farghly
An experiment was conducted to compare the effect of housing system on performance of pigeons. A total of 16 pair of parent Baladi pigeons (6-7 months old) were distributed equally according to their consistent mating systems (sex ratio of pigeons 1:1) to 2 treatments 8 pairs (4 replicates of 2 pairs each). Birds were reared under similar environmental conditions. The first group was housed indoor system and served as a control (C). The second group (treatment) was housed in outdoor system. Feed and water were offered ad libitum along the experimental period. Results obtained are summarized as follow:1- Housing system had significant (P≤0.05) effect on squabs weight gain at 28 days of age, mortality percentage and economic efficiency. 2- Indoor system decreased feed intake for pigeons without or with squabs. 3- Egg number, egg weight, fertility and hatchability were significantly (P≤0.05) increased in outdoor system. 4- Pigeons reared in indoor system had significantly the highest number of weaned squabs, body weight and weight gain during 28 days of age. It can be concluded that pigeons housed indoor system gave the best squabs performance as compared with outdoor system. However, pigeons housed outdoor system was better than the indoor system for reproductive performance of local Baladi pigeons.

M.
Farghly
Seven hundred and twenty, four weeks old Dandarawi chicks were used to study the effects of light source on growth performance and carcass traits. Chicks were divided into 3 equal groups (240 birds each) and housed in floor pens. The first group used as control and reared under incandescent light bulbs (IL), while the second and third groups reared under fluorescent (FL) and saving light bulbs (SL), respectively. All birds were raised under photoperiod of 12 hours per day, with light intensities of 5-10 Luxes. Feed and water were available ad lib. and all the other conditions were the same during the experimental period. Results showed that birds reared under SL and FL bulbs had significantly (P≤0.05) higher body weight (BW), daily weight gain (BWG), liver and giblets percentages than the control group. Also, birds reared under IL bulbs had significantly (P≤0.05) higher plumage condition and tonic immobility as compared to the other two groups. No significant differences (P≤0.05) were found between groups in leg problems, dressed carcass, drumsticks, femurs, breast, heart and gizzard among all groups. Finally, the economical efficiency of the birds reared under SL and FL bulbs was better than the IL groups during the growing period by 26.4 and 36.1%, respectively.

Influence of Housing Systems As Stock Density on Carcass Characteristics and Meat Quality of Broiler Chickens In New Valley
A total number of one hundred and twenty birds of Cubb broilers were used to study the effect of stock density on carcass traits and meat quality of broiler chickens. The stock density in pens varied in size to produce 4 different stocking densities: 10 birds/m2, 14 birds /m2, 18 birds /m2 and 22 birds /m2 (3 replicates each). The obtained results indicated that stock density groups had significant (P≤0.05) effect on dressed carcass, breast, liver, all fat percentages, carcass lengths, fatness and protein percentages of meat content. Also, significant effects were found on carcass lengths, tenderness, texture and water holding capacity (WHC) of meat. However, no significant differences in percentages of drumstick, heart, wings, neck, moisture, ether extract, ash, and P levels were found among all groups. Also, stock density did not differ statistically for carcass conformations, aroma, taste, flavor, Lean: bone ratio and meat pH. It could be recommended that stock density (400 cm2 / bird) could be applied successfully by the farm managers to have a better carcass traits and meat quality without any significant negative effects on production process.

Evaluating Different Types of the Floors for Housing Broiler Chickens in New Valley
The purpose of this research was to study the effect of different floor types on performance, airborne quality and physiological state of broilers. The research involved 180 broilers aged 1 days which were raised up to 42 days. Floor types consisted of cement, wheat straw litter, wire net, plastic net, wooden slats, palm fiber mate, palm slats and palm spines mate floors. The achieved results showed that the floor types had significant effect on final body weight, feed conversion, some blood parameters, body temperature, viability rate and tonic immobility, however, there are no significant differences in plumage conditions and some carcass traits. Broilers in the wooden slats and palm spines mate floors had immune organs weight compared to the other floors. Also, broilers in the wooden slats and plastic net had average humidity level lower than broilers in the other floors. It could be concluded that wooden slats and palm spines mate floors best being used for broilers. However, palm slats (having less health problems than other floor) is recommended as a safe and economical replacement as floor for any floor.

Use of Some Available Plant Residues in New Valley as Alternative Litter Materials for Managing Broiler Chickens
This experiment carried out to determine the effects of using some alternative litter materials on the growth performance, litter conditions, airborne quality and health traits of broiler chickens, one hundred and eighty, 1 day old broiler chicks were reared for six weeks and housed in pens in six equal groups (3 replicates of 10 birds each). Wheat straw (control), wood shaving, rice hulls, corn stalks chips, chopped palm fiber and palm spines chips were used as litter materials in this the study. Wheat straw, wood shaving, rice hulls, corn stalks chips, chopped palm fiber and palm spines chips did not differ statistically for body weight, feed consumption, feed conversion ratio and survivability (p>0.05). However, body weight tended to increase on wood shaving and palm spines chips. Carcass weight and gizzard yield were significantly (p < 0.001) higher for birds raised on corn stalks chips maintained approximately 10% lower moisture level in comparison to Wheat straw and wood shaving. The lowest bacterial counts and moisture content of used litter was found in corn stalks chips followed by palm spines chips, wood shaving, rice husk, wheat straw and chopped palm fiber. There was no statistically significant effect between type of litter on litter pH, litter temperature and body conformations. Depends on the price and availability palm spines can be used as litter material instead of wood shaving and wheat straw. In conclusion, corn stalks chips, chopped palm fiber and palm spines chips can potentially be used as alternative litter materials in New Valley for growing broilers.

Biometric Testicular and Hormonal Serum Profiles of Arabian Stallion during Breeding Season in Algeria
Several studies have shown relationship of biometric testicular, hormonal profiles and fertility. Objective of present research were to predict the fertility of stallion by biometric testicular and hormonal analysis. Measurement of the testis of adults Arabian stallions (n=36) from National Haras Chaouchoua of Tiaret, Algeria. The length (TL), the width (TW), the height (TH), and the scrotal width of the testicles (TSW) during three consecutive seasons (April: 2014-2016). From these measurements, the total testicular volume (TTV), the daily sperm output (DSO) and the daily sperm product (DSP) were calculated. The serum testosterone concentration, the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH) were also evaluated by IMMUNOTECH® during April 2016.The scrotal width (TSW: 11.06 ± 1.55) cm, was very highly correlated to the age and the body weight of the stallions as well as with all the testicular parameters (p < 0.01). The scrotal width (TSW) was correlated positively to testosterone, (r=0,14).The examination of the testicular size is an important criteria to estimate for selection the stallions with highest fertility potential.

The aim of this study was to investigate the effects of feeding a formulated from local feed sources with using discarded Dates, Palm leaves and its combination on growing Ossemi male lambs growth performance, diet digestibility, blood metabolites and profitability in New Valley Governorate. Forty nine Ossimi male lambs with average body weight 24.82 kg )4-5 months of age( were divided randomly to seven groups (seven lambs per each group) were fed individually. Frist group lambs were fed the control diet (0% discarded Dates and 0% Palm leaves). The second and third group of lambs were fed an experimental diet contained 7.5 and 15% of discarded Dates, respectively; the fourth and fifth group of lambs were fed an experimental diet contained 6 and 12% of Palm leaves, respectively; the sixth group of lambs were fed an experimental diet contained 7.5 % of discarded Dates and 6% Palm leaves; the seventh group of lambs were fed an experimental diet contained 15 % of discarded Dates and 12% Palm leaves during 120 days of feeding period. All lambs in each group individually weighed to the nearest gram monthly till the end of experimental period. Animals were housed individually in clean and hygienic pens. Body weight was measured weekly and feed consumption was recorded daily. Digestibility trial was conducted and digestion coefficient was calculated for diet dry matter (DM) and nutrients. At the end of experiment, blood samples were collected for analysis. Economic efficiency (profitability) was evaluated for using discarded Dates, Palm leaves and its combination in the diet. Results showed that there were no significant differences between groups in growth performance parameters between groups. Similar findings were recorded for digestibility of DM and nutrients. Addition of discarded Dates, Palm leaves and its combination in the diets did not negatively affect blood metabolites. Economical profitability was significantly found when feeding 12% Palm leaves (T4); 15% discarded Dates and 12 % Palm leaves (T6) in the diet. It can be concluded that discarded Dates, Palm leaves and its combination can be utilized effectively in the diet without adverse effect on growth performance, digestibility blood metabolites of Ossimi lambs.

The Effect of Adding Different Types of Vegetable Oils and Waste Frying Oil on the Productive and Reproductive Performance of Japanese Quail
This study was carried out to evaluate the effect of adding different types of vegetable oils in improving production and reproduction performance and egg quality of Japanese quail. A total number of 112 birds of the 6-weeks Japanese quail were used and randomly distributed on four treatments with 4 replicates per 7 birds (2 males and 5 females). The bird were fed by treatments the following treatment: the first treatment (a control 2.5 % commercial oil (a mixture of soybean oil, sunflower oil and cotton seed oil)), the second (2.5% corn oil), third (2.5% sunflower oil), and fourth (2.5% waste frying oil -frying fish-(commercial oil)). Body weight (BW), body weight gain (BWG), feed consumption (FC), feed conversion ratio (FCR), egg production, egg weight, egg mass, fertility, hatchability, weight of chicks at hatch, egg quality, and relative economic efficiency (REE) were estimated for the whole experimental period (10 weeks).
There was no significant effect on egg number, egg mass, egg laying rate, feed intake and FCR, except for egg weight, which was higher for birds fed sunflower oil and waste frying oil compared to the second group (corn oil). Lipid sources evaluated had no significant difference (p > 0.05) for yolk weight, yolk percentage, albumen percentage, eggshell percentage, shape index, yolk index, Haugh unit (HU), shell thickness and SWUSA between the treatments applied. However, albumen weight, eggshell weight, and width of egg increase significantly (P >0.05) due to addition sunflower oil compared with addition of corn oil, and increase significantly (p > 0.05) shell strength and ESA comparing corn oil group or control group. There were insignificant differences in fertility and hatchability rate between the experimental treatments. However, body weight of chicks at hatch increased significantly (p > 0.05)) due to addition sunflower oil comparing the other treats and increase significantly due to waste oil by comparing the control treat and corn oil treat. It was observed that treatment the quail birds with different types of vegetable oils have no significant effect on body weight of these birds during the experimental period. Replacement of commercial oil with waste frying oil has led to higher economical efficiency. However, addition of corn oil has led to lower economical efficiency.

Effects of Punicalagin and Its Combination with Hcg on Some Productive And Reproductive Traits In Virgin Rabbit Does
Unsurprisingly, the potential antioxidant means potential pregnancy outcomes. Punicalagin as potential antioxidant is demanded for reproductive health and progesterone adequacy is necessity for maintaining pregnancy in young does. So, the aim of study was to investigate effects of punicalagin (PL) and its combination with human choronic gonadotropin (HCG) on maternal live body weight (MLBW), number of services/conception (NS), conception rate (CR), gestation length (GL), kindling rate (KR),total litter size (TLS), live litter size (LLS), kit weight (KW), progesterone (P4) and estradiol-17(E2) concentrations at 1st and 2nd pregnancy of young does. A total of 28 healthy virgindoes (6 months old) were divided into 4equal groups. Group I, each doe was injected IM with 100 ug PL twice/week pre-mating and one time 3 days post-mating.Group II, each doe was injected IM with 25 IU human gonadotropic hormone (HCG) one time 3 days post-mating.Group III, each doe was injected IM with combination PL+HCG. Group IV,each doe was injected IM with sterilized water (control). Blood samples were taken at pre-mating, mating, post-mating, throughout pregnancy and immediately post-kindling for assaying P4 and E2. All does were naturally mated with fertile bucks. Results revealed that PL and combination groups displayed their significant impacts on MLBW, NS/conception, CR, GL, KR, TLS, LLS, KWs (birth and weaning), P4 and E2 concentrations either at 1st/2nd pregnancy or both of them. Conclusively, PL and PL+HCG improved pregnancy outcomes of young does particularly at 2nd pregnancy and could be recommended in rabbit's farms.

Abd El-Dayem
Two laboratory experiments were conducted out at Agricultural Botany Department, Faculty of Agriculture, Moshtohor, Benha University , Qalyubia Governorate, Egypt, during two successive seasons of 2016 and 2017. The objective of this study was to evaluate the effect of soaking of seed with benzyl adenine (BA) at (25, 50 and 100 mgl-1), paclobutrazol (PP333 at (5, 10 and 20 mgl-1), algae extract at (5,10 and 20 ml-1), mineral nutrients (Ca, Mg and Fe chelated) at 500 mgl-1 and treatment of lithovit at 500 mgl-1 on seed germination (percentage, rate) and seedling growth of Moringa oleifera plant.
The obtained results reported that seed soaking with benzyl adenine (BA) at different tested concentrations enhanced seed germination and seedlings growth traits during the two seasons of study. Also, soaking seeds in 100 mgl-1 benzyl adenine (BA) reflected the highest values of seed germination (rate and percentage) as well as growth of seedling measurements i.e., The radical and plumule lengths at 7, 10 and 13 days from soaking and absolute growth rate of root and stem after 10 and 13 days of seed treating followed by using lithovit at 500 mgl-1, Algae extract at 20 mll-1, benzyl adenine (BA) at 50 mgl-1., mineral elements at 500 mgl-1 and benzyl adenine the at the lowest concentration i.e., 25 mgl-1 in descending order.
On contrary, germination of seeds and seedlings growth traits were significantly decreased with paclobutrazol treatments in both seasons compared with the control treatment.

Using of Some Antioxidants for Cotrolling of Mosaic Causing Viruses on Vegetables In Minia Governorate, Egypt.
O.I.
SALEH
In previous works, it has been reported that three viruses affecting some economic vegetable crops and causing severe losses in yield.These viruses, were cucumber mosaic virus (CMV), hibiscus chlortic ringspot virus (HCRSV) and potato virus Y (PVY) .The effect of aquaeous extracts of some medicinal plants on diseases caused by these viral was reported in previous paper (Saleh et al., 2019). This paper delt with the effect of some antioxidants in cotrolling these virus diseases. The antioxdants are ascorbic, benzoic, citric, and salycylic acids at different concentration (50, 100, and 200 ppm). Application , of some antioxidants either as soaking host seeds or spraying before inoculation have marked inhibitory effect and reduced disease infection and alleviated symmptoms particularly at older ages.

Efficacy of some Bio-agents, Chemical Inducers and Fungicides in Controlling Tomato Root Rot Disease Caused by Rhizoctonia solani
Heba E.
Aboelmagd
Root rot diseasecaused byRhizoctonia solani; is one of the most common destructive tomato diseases. Many different agents i.e., biological agents, chemical inducers and fungicides were investigated for their antagonistic effects on growth of R. solani in vitro. The obtained results showed that, maximum inhibitory effect “100%” was obtained by most tested fungicides i.e. Rizolex–T, Maxim-XL and Moncut followed by salicylic acid at 8mM as chemical inducers. Also, Glomus sp and T. viride as bio-agents were most effective treatments against R. solani where they inhibited the growth of R. solani by 67.22 and 64.07%, respectively followed by oxalic acid at 8 mM and K2HPO4 at 15 mM treatments which recorded 59.6 and 44.1%, respectively. Meanwhile, chitosan treatment was the least inhibitive treatment in vitro. Under greenhouse conditions, chitosan was the highest effective treatment in reducing incidence severity of tomato root rot disease as well as increased the assessed vegetative parameters. Moreover, all tested treatments clearly increased the total phenol content and activities of plant defense-related enzymes. As for tomato root anatomy, most treatments increased root diameter of treated tomato plants. Where, T. viride followed by B. subtilis treatments were the best comparing with control treatment.

Genetic Variability, Heritability, Genetic Advance, and Correlation Analysis in F2 Segregating Population of Tomato (Solanum lycopersicum L.).
A. A.
Al-Araby
Tomato is one of the most important vegetable crops grown in Egypt. We aimed to investigate the genetic variability parameters, heritability, genetic advance, and correlation coefficient analysis for some important traits. Therefore, we evaluated the cross Ms35 × I-4, along with its parents and F2 generation, at Ad-Daljamun village, Kafr El-Zayat, Egypt, during the 2017 summer season. High genotypic coefficient of variation (GCV) was found for average fruit weight, number of fruits per plant, and weight of fruits per plant. Heritability in broad sense was very high for number of fruits per truss, number of days to 50% mature fruits, average fruit weight, total soluble solids content, number of fruits per plant, and weight of fruits per plant. The genetic advance as percentage of the mean (GA%) was high for number of flowers per inflorescence, number of fruits per truss, average fruit weight, number of fruits per plant, and weight of fruits per plant. Generally, average fruit weight, number of fruits per plant, and weight of fruits per plant, had high values of genotypic coefficient of variation, heritability, and GA%, therefore, they are important for the direct selection. The correlation coefficient analysis indicated a high association between weight of fruits per plant and average fruit weight, also, between number of fruits per plant and each of number of inflorescences per plant, number of flowers per inflorescence, and number of fruits per truss. Moreover, a high correlation was found between number of flowers per inflorescence and number of fruits per truss.

Efficiency of Three Breeding Methods on Three Bread Wheat Populations
K. A.
Bayoumi
The present study was carried out at the Experimental Research Station of Moshtohor, Benha University, Qalubia Governorate, Egypt during the three successive seasons of 2015-2016, 2016-2017 and 2017-2018. The present study aimed to evaluate the efficiency of three methods of selection used in the wheat breeding program namely; pedigree method (PM), bulk method (BM) and single seed descent method (SSDM). The final evaluation of the F5 generation of three crosses i.e.,Sids 12 × Line 116, Gemmiza 11 × Line 145 and Gemmiza 11 × line 124 was done during 2017/2018 season. The high yielding selected lines were evaluated in nested design with three replications in each cross. The efficiency of the breeding methods was evaluated on the basis of the following parameters: mean performance results in the first cross (Sids 12 × Line 116) indicated that, the differences between breeding methods. The pedigree method gave the highest values for grain yield/plant and number of spikes/plant. While the Bulk method gave the highest values for 1000-kernel weight, however, single seed descent (SSD) method exhibited significantly for number of kernels/spike. Pedigree method is considered the best breeding method for grain yield/ plant, number of spikes/plant and the second for 1000-Kernel weight, than those bulk and SSD method in this cross (Sids 12 × Line 116). The pedigree method produced consistently more superior lines for grain yield/plant compared to the best parent or the average population. The best lines were number No. 7 (67.97 g), No. 5 (66.61 g), No. 9 (64.6 g), No. 19 (63.48 g), No. 8 (60.19 g), No. 20 (59.11 g), No. 4 (58.89 g), No. 2 (57.36 g), No. 3 (56.18 g) No. 18 (55.47 g), No. 13 (55.21 g), No. 17 (54.83 g), No. 16 (54.24 g), No. 15 (54.21 g) and No. 12 (52.51 g) for pedigree method. But in bulk method line No. 19 (57.76 g) was more superior compared to the best parent or the average population. The mean squares for breeding methods in the second cross (Gemmiza 11 × Line 145) were significant for yield and its components. The pedigree method gave the highest values for grain yield/plant, number of kernels / spike, number of spikes / plant and 1000- kernel weight. Pedigree method is considered the best breeding method for grain yield/ plant, number of spikes / plant, number of kernels / spike and 1000- Kernel weight, than those SSD and bulk methods in this cross (Gemmiza 11 × Line 145). The pedigree method produced consistently more superior lines for grain yield / plant compared to the best parent or the average population. The best lines were number No. 5 (59.01 g), No. 14 (57.44 g), No. 15 (56.29 g) and No. 16 (56.29 g) for pedigree method. There aren't any lines significant higher in bulk method and single seed descent method than the best parent in this cross. The mean squares for breeding methods in the third cross (Gemmiza 11 × line 124) were significant for yield and its components. The pedigree method gave the highest values for grain yield / plant, number of spikes / plant, number of kernels / spike and 1000-Kernel weight. Pedigree method is considered the best breeding method for grain yield / plant, number of spikes / plant, number of kernels / spike and 1000-Kernel weight, than those SSD and bulk method in this cross (Gemmiza 11 × line 124).

Combining Ability Analysis Using Diallel Crosses among Nine Inbred Lines of Corn under Two Nitrogen Levels
mohamed
gad
A half diallel cross between 9 inbred lines of maize was evaluated at two different nitrogen levels(60 and 120 kgN/fed.) for nine quantitative characters. Nitrogen level and crosses mean squares were significant for all traits under study. Significant crosses x nitrogen level mean squares were obtained for all studied traits except, No. of rows/ear. General and specific combing ability mean squares were significant for all traits, except days to 50% tasseling date. For days to tasseling and no of rows/ ear at low nitrogen rate; silking at high nitrogen level; shelling% at high nitrogen level and combined analysis and plant height, ear height, no of kernels/ row, 100 kernel weight and grain yield/ plant in both and across nitrogen levels. High ratios which largely exceeded the unity were obtained, indicating that a large part of the total genetic variability associated with these traits was a result of additive and additive by additive gene action. For remain cases, GCA/SCA ratios were less than unity. Therefore, it could be concluded that the large portion of the total genetic variability for these traits was due to non-additive gene action. The parental inbred lines No. 1, 6 and 7 gave positive and significant () effects for grain yield/ plant and one or more of its components. The parental combination P1xP3, P1xP4, P1xP5, P2xP4, P2xP7, P2xP9, P3xP4, P3xP5, P3xP6,, P4xP6, P5xP6, P6xP7, P6xP9, P7xP8 and P7xP9 for grain yield/plant exhibited significant positive effects being 62.61, 20.37, 92.43, 42.37, 42.06, 17.94, 12.38, 10.57, 21.08, 53.52, 7.27, 14.95, 13.53, 42.00 and 49.83, respectively. The crosses 1x3, 2x7, 7x8, 7x9, 8x9 in low nitrogen environment, 1x3, 1x4, 1x5, 1x7, 2x4, 2x7, 6x7, 7x8, 7x9 and 8x9 at low nitrogen environment and 1x3, 1x5, 2x4, 2x7, 6x7, 7x8, 7x9 and 8x9 in the combined data gave the highest mean value of grain yield / plant.

Knowledge of type of gene action controlling target traits and genetic behavior is a basic principle for designing an appropriate breeding procedure for the purpose of genetic improvement. Hence, the success of any selection or hybridization breeding program for developing varieties depends on precise estimates of genetic variation components for traits of interest which may be additive, dominant and non-allelic interaction effects. Heterosis and nature of genetic effects on ealiness and yield traits were studied in a 10x10 diallel cross without reciprocals in wheat to define and select efficient and prospective material for immediate use in hybridization programs to improve grain yield of wheat in Iraq. Parents and F1 were evaluated using (RCBD) with 3 replications for quantitative traits in (2017/2018) season. Significant genotype mean squares and its components (parents and crosses) were obtained for all traits in both generations. Significant heterosis in F1 generation was obtained for all studied traits. The useful heterosis of grain yield plant-1 relative to better parent varied from 12.46 to 36.82% in F1 crosses. The P7(Millan)xP8(Hithab) and P7(Millan)xP9(Ibaa 99) were the best crosses for grain yield heterosis. General (GCA) and specific (SCA) combining ability mean squares were significant for all traits. MS (GCA)/ MS (SCA) ratios indicated the relative importance of additive and additive by additive gene action in their inheritance for all the traits except for earliness and no. of spike plant-1. The three parents P1(Abu-Graib), P3(Osais), P5(Florka) and P9 (Ibaa 99) gave the highest positive significant effects for grain yield plant-1 in the F1 crosses. Twelve crosses showed significantly desirable heterotic effects for grain yield most studied traits.

This investigation was carried out to study the possibility of using in vitro technique for propagation Blackberry (Rubus sp < /em>) Prime-Ark 45 cultivar. Explants of Blackberry Prime-Ark 45 cultivar were sterilized in 0.1% of sodium hypochlorite for 15 min to get aseptic culture. In starting stage, tow explants shoot tips and axillary buds were cultured on MS media supplemented with NAA at 0.0, 0.01 and 0.1 mg /L and BA at 0.0, 0.5, 1.0 and 2.0 mg /L in addition to sucrose at 3% and agar at 7 g/L. The results of starting stage showed that adding the combination between BA and NAA at 1.0 and 0.01 mg/L respectively to MS media caused the highest shoots number and shoot fresh weight compared with control and other treatments. The axillary buds were superior to shoot tips explants regarding survival percentage and other morphological characteristics. The highest shoots number and shoot fresh weight (g) were obtained when micro-shoots of tested CV., cultured on MS media supplemented with BA and KIN both at 1.0 mg /L compared with those of control and other treatments. Cytokine BA was superior to KIN regarding to mass production at multiplication stage. Halh-strenght MS media supplemented with 1.0 mg /L of NAA and IBA caused the highest root formation percentage, roots number and root length (cm) for micro-shoots of Blackberry Prime-Ark 45 variety. IBA was superior to NAA regarding roots number and root formation percentage at rooting stage. The highest root length (cm) was obtained when micro-shoots of the tested cv., were cultured on MS media supplemented with NAA at 2.0 mg /L compared with the same concentration of IBA.

Standardize in-vitro regeneration protocol in producing disease free; true-to-type and homogeneous high quality plants are prerequisite. Nucellar tissues from immature mango fruits of poly-embryonic rootstocks. The two mango rootstocks were cultured on full strength of B5 and MS media supplemented with different concentrations of some amino acids and vitamins. Embryos of (Saber and 13-1were used as a source of immature embryos (after pollination and fertilization stages) as explants. All 15 of day-old immature embryos of Sabre and 13-1 mango rootstocks were died after two months, while all other embryo ages 20, 30, 40, 50 and 60 day-old were growth after the same time, also the best germination percentage, when immature embryos were cultured on the same media after 40 and 50 days from pollination and fertilization stages. MS media supplemented with 2.0 mg /L of BA possessed the highest embryos number per germinated embryo compared with another rootstock on the same media. The highest germinated embryos achieved when somatic embryogenesis of tow mango rootstocks were cultured on half – strength MS media were supplemented with 30% sucrose compared with other treatments. Half-strength MS was superior to full-strength MS media on germination stage. Saber mango rootstock was superior to 13-1 rootstock regarding to the direct somatic embryogenesis; development of embryos; large scale somatic embryogenesis and the highest germination percentage and number of germinated embryos; on the other hand, Saber mango rootstock was least mango rootstock regarding the highest death percentage of embryos compared with 13-1 mango rootstock. It could be recommended that somatic embryogenesis technique possibility of a rapid multiplication on the mango rootstocks saber and 13-1 grew into plantlets.

Isolation, Characterization and Identification of Lactic Acid Bacteria as Probiotic
Abou-Aly
Hamed E.
Lactic acid bacteria that grow as the adventitious microflora of foods or that are added to foods as cultures are generally considered to be harmless or even an advantage for human health. The objective of this study was to isolate, screen and identify lactic acid bacteria from different sources. As well, evaluate the more potent lactic acid bacteria isolates for their probiotic characteristics. Ninety-six bacterial isolates were isolated from different 18 sources, 51 (53%) isolates were able to hydrolyze 0.5% bile salts while 28 isolates were able to hydrolyze 1% bile salts. Also, only 11 isolates were able to tolerate 2% bile salts after 6h incubation periods. On the other hand, lactic acid bacteria isolates were able to survive at pH 1.5 and 3.0 as well 8.0. Also, these isolates were potent for cholesterol assimilation, NaCl tolerance, exopolysaccharides production, antioxidant activity. Lactic acid bacteria isolate MS87 that exhibited excellent probiotic characteristics was identified using 16S rRNA sequence as Pediococcus pentosaceus. This study led to suggest that environmental-derived lactic acid bacteria-strains could be used as a potential source of probiotic.

Farhat
Fouda
Hared lignocellulosic structure of rice straw is the main hindrance in biogas production process. Thus, laboratory scale batch experiment was conducted to study the effect of different pretreatments of rice straw on anaerobic digestion. For this reasons, different pretreatments of rice straw prior anaerobic digestion was run using chemical activator, cattle dung, Tricoderma viride, phanerochaete chrysosporium and effective microorganisms under aerobic and semi aerobic conditions to study the effect of these pretreatments on the speed and production of biogas. The results indicated that semi aerobic pretreatment has significantly increased the production of biogas more than aerobic pretreatments. The highest yield of biogas and methane production were obtained after anaerobic digestion process at three days from pretreatments. Pretreatment T4 (rice straw + cattle dung + effective microorganisms + starter) achieved in semi aerobic in biogas and methane higher than aerobic pretreatments where, obtained 9.37, 5.94 L biogas and 5.42, 3.22 L methane, respectively. Biogas and methane production rates were based on either total solid or volatile solid where, ranged between 46.60- 381.83 L/Kg consumed biogas and 18.98- 220.86 L/Kg consumed methane. Volatile fatty acids concentration were increased during pretreatments to reach the highest concentration after three days, then decreased subsequently, meanwhile the concentration decreased after anaerobic fermentation process. Also, the pH values increased at the end of anaerobic digestion the values ranged between 7.02-8.28.Ammonical- N concentration was decreased during pretreatments to reach its lowest the concentration after seven days, then decreased at the end of fermentation process where, ranged between 23-138 mg/Kg in final anaerobic digestion process. Pretreatment T4B3 (rice straw + cattle dung + effective microorganisms + starter) after three days from semi aerobic led to the best biogas manure which contents much humic substances.

The aim of current study was to evaluate the effect of distillation time and storage conditions up to 12 months on quality and stability of Egyptian and Syrian cumin essential oil. The distillation time were run as 3 fractions (F1: first 6 h; F2: between 7 and 8 h; and F3: between 9 and12 h. The stability, physicochemical, and composition of cumin oil at room temperature and refrigerator up to 12 months were evaluated. The results demonstrated that the yield percentage of Egyptian cumin essential oil (ECEO) was (5.59%) and Syrian cumin essential oil (SCEO) was (3.36%). The oil produced at first 6 h of distillation (F1) with best quality (~90%), followed by F2 (~7.50%) and F3 (2.50%). The 18 compounds were identified in CEO and the main compounds were cuminaldehydes, β-pinene, β-myrcene, p < /em>-cymene, d-limonene, and g-terpinene. In addition, the results demonstrated that storage at different temperature influences on the quality and composition of cumin oil especially at room temperature. During the storage the components i.e. a-pinene, β-pinene, β-myrcene, d-limonene and g-terpinene were decreased, while p < /em>-cymene was increased however, cuminaldehyde increased during 12 months at room temperature compared with refrigerator. The sensory attributes of CEO stored at refrigerator was significantly higher than room temperature. These results confirmed that ECEO is better than SCEO during processing and more stable during storage.

A. cepa and V .faba have been widely accepted for evaluation of genotoxicity and the assay is well known and commonly used in many laboratories in good correlation with results from other established test systems. .A. cepa has relatively large monocentric chromosomes and accepted as suitable test organism for the study of environmental mutagenesis.Also V. faba beans was used as indicator to determine genotoxic effect of synthetic dyes used as food additives. The mitotic index is one of the mitotic parameters, which reflects the genetic. control system of division and the existence of chromosomal aberrations in several organisms In the present work, the genotoxic effects of three food colorants on two types of living organisms i.e. (Allium cepa and Vicia faba) plants were studied. The three food colorants were (Ponceau 4R, Sunset yellow and Tartrazine). Each colorant was used in three concentrations 0.25%, 0.50% and 1.00%. The results showed that all synthetic food colorants which used in the experiment decreased the mitotic indices in V.faba and A.cepa . Moreover the synthetic food colors disturbed the percentages of mitotic stages and the chromosomes behavior and configuration during the mitotic division. Also, the study compared the effects occurring at molecular levels in Allium cepa and Vicia faba exposed to colored food at 1% concentration aqueous solution. The qualitative modifications arising in random amplified polymorphic DNA (RAPD) profiles as a measure of DNA effects were compared with control. Results showed that treatments of the above test samples reflect changes in RAPD profiles. Changes in RAPD patterns included variation in band intensity, loss of normal bands and appearance of new bands compared with control. More over the ability of different primer for producing DNA fragment is varied from genome to other. The results indicated that DNA polymorphism.

The main aim of this study was to introduce HVA1 gene into Catharanthus roseus callus by using PDS (Particle delivery system). In vitro seed germination of C. roseus was achieved using vigor seeds. The shootlets induction medium was MS containing 2.0 mg/l benzyl aminopurine l−1. Somatic embryogenesis was obtained by culturing various parts of explants (stem, root and leaves disc) on MS containing 2, 4-D at 3.0 mg/l and sub-cultured on MS medium containing coconut juice 3%. Genetically transformed C. roseus somatic embryos were obtained after bombardment of embryonic calli, by pAB1 plasmid harboring HVA-1 gene, salt resistance, and Bargene, herbicide resistance, coated gold particles 1.0micron, 1100 and 1350 Psi with 130 mm with HAV1 gene. The data showed that the transgenic line exhibited different levels of salt tolerance as expressed by the performance of plants dry weight, proline content and drought tolerance test. HVA-1 gene enhanced vinca salt tolerance hence enhancing the production of the important secondary metabolites from transgenic plants. The results of the present study can be seen as a step towards development of salinity tolerant transgenic vinca genotypes.

Molecular Studies and Soma-Clonal Variations in Some Potato Genotypes
Reham R.
Mohamed
Potato is the fourth most important crop of the world wide annual production approaching 300 million tons. The tuber, the most important part of the plant, is an excellent source of complex carbohydrates, proteins, and vitamins. Salt accumulation is one of the main factors that diminish crop productivity since most of the crops are not halophytic against its toxic effects on plants also lead s to loss chloroplast activity as metabolic changes. The main objective of this study was to examine the powerful tissue culture system with three different potato genotypes. In addition to induce genetic variabilities through soma-clonal variation. Moreover, evaluate saline, and drought tolerance within the obtained clones.Results show that, The Shoot number of the three potato genotypes significantly affected by the two concentrations of sodium chloride (1000 and 2000 ppm).The shoot number of Daimont genotype was highly significant decreased in respons to the salt trearments (3.68 at 1000 ppm and 3.96 at 2000 ppm as compared with the control, 5.91). While shoot length of the three studied potato genotypes was affected by six combinations of plant hormones (auxin cytokinin) especially sponta (3.489). Trehalose,in three concentrations, exhibited an effect on shoot length of the three potato genotypes under study. Results of the molecular genetics study using IssR, showed the presence of polymorphic bands in variants and mutants suggesting that in response to all the studied treatments comparing with control.

Characterization of Some Rhizobia Isolates From Various Legumes on Morphological, Biochemical and Molecular Criteria
Enas
Abd EL-ghany.
This research was conducted to characterize 24 rhizobial isolates from five legumes on morphological, biochemical, molecular aspects and determine the phylogenetic relationships among them. Rhizobial isolates were obtained from five Egyptian legumes; faba bean, lentil, pea, clover, and soybean. Morphological characterization classified isolates into fast and slow growers. Biochemical characterization using API 20E and API 20NE systems showed large diversity which may reflect their adaptation in different environments. Moreover, molecular detection for 16S rDNA gene characterized 19 of them to species level. Isolates from pea, faba bean, clover and lentil came to be Rhizobium leguminosarum and isolates from soybean were Bradyrhizobium japonicum. These data reflected a narrow diversity of rhizobia in Egypt. Phylogenetic analysis of the 19 isolates confirmed that the Bradyrhizobium japonicum isolates were divergent from all other isolates. Also, the phylogram revealed that each group of isolates originated from root nodule of a certain legume formed a separate sub-cluster. Besides a narrow range of interspecies variations was found which is consistent with the idea of biovars presence among species.

M. A .
Elbath
This study was designed to identify the urinary volatile compounds present in urine of male and female mice Mus musculus in order to detect the most attracting compounds to both sexes to use these compounds as a sex attracting material to enhance the efficiency of rodent bait. The urine of adult male and female mice were collected and analyzed by GC-MS. The result of chemical analyze revealed presence of many volatile compounds in urine of both sexes. From the identified compounds Phenol, 3-ethyl, 1,8-Nonadien-3-ol, 5-Octadecenal, Octadecane, 5-methyl- and 4-ethyl phenol were detected in male urine and Phenol, 2-ethyl- (CAS), and Phenol, 3-ethyl- were detected in female urine. Synthetic compounds similar to identified ones were purchased, different concentrations (0.5, 1, 5, 10 and 100%) were prepared from each chemical compound and the respose of tested animals toward these compounds in different concentration were evaluated by using Y- maze apparatus. The number and duration of visits of animal toward chemicals were recorded. Obtained results showed that Phenol, 2-ethyl- (CAS), Phenol, 3-ethyl and 4-ethyl phenol are the most attracting chemical compound in males, while 4-ethyl phenol and 2-ethyl- (CAS), Phenol is the most effective one in females. Food consumption was affected in both sexes by mixing of the isolated compounds individually by concentration 1 and 5 % with animal diet, the highest food consumption in both sexes was scored by addition of 20% solution from 4-ethyl phenol 5%.

Walid
Moghith
This study was conducted at the Experimental farm of the Heliopils University, El Sharqea, Egypt during the two successive seasons of 2016/2017 and 2017/2018. The aim of this study was to investigate the possibility of improving growth, seed yield, oil productivity and fixed oil constituents of chia (Salvia hispanica L.) plants grown in sandy soil by using arbuscular mycorrhizal fungi (AMF) and some phosphorus sources i.e., phosphate rock - super phosphate - monoamonium phosphate (MAP) and phosphoric acid (30 units P2O5).
Seeds of chia (Salvia hispanica L.) were inoculated with mixed spores of arbuscular mycorrhizal fungi (AMF) from genera Glomus, mosseae and fasciculatum [275 Spores/g oven dry basses in addition to the colonization root pieces (the infectivity 104 propagola) sterilized peatmoss: vermicolite: perlite as a carries] at the rate of 20g /5g of seeds and after 10 days by injection into the soil at 3.5 g/hill.
The obtained results indicated that, plants receiving mycorrhizal fungi inoculum gave the significantly highest mean values for most of studied characteristics (i.e., plant heigt, number of branches per plant, plant fresh and dry weights, seeds yield/plant and/or feddan, weight of 1000 seeds, chlorophyll "a, b,", carotenoids, N, P, K, total carbohydrate, fixed oil percentage, fixed oil yield /plant and/or feddan and fatty acids constituents of chia (Salvia hispanica L.) plants, while uninoculated plants (control) gave the lowest values. Whereas different sources of phosphorous fertilizers statistically affected most of the mentioned parameters, especially monoaminum phosphate treatment (MAP) in both seasons. Moreover, all the combination treatments between inoculated with AMF, uninoculated and phosphorous sources improved all the studied parameters. The recorded results indicated that, the combined treatments between mycorrhizal fungi inoculated and MAP gave the highest values for most recorded parameters, i.e., chlorophyll a, b, total carotenoids, N, P, K, total carbohydrate contents, fixed oil percentage, fixed oil yield/plant and/or feddan as compared with the other combined treatments both seasons. Meanwhile, the combined treatments of inoculation with the mixed spores of arbuscular mycorrhizal fungi and phosphoric acid induced highly significant increments in this concern in both seasons. Chromatography analyses of chia fixed oil revealed the identification of 23 components, the main component was α-linolenic acid (54.96 to 63.23%). The major components were α-linolenic acid, linoleic acid, oleic acid, and palmitic acid. It can be concluded that the inoculation with the mixed spores of arbuscular mycorrhizal fungi and monoamonium phosphate (MAP) was the best for improving growth, seeds yield, fixed oil productivity, chemical compositions and fixed oil constituents of chia (Salvia hispanica L.) plant.

Effect of Germination Media and Saline Water on Germination of Chia (Salvia hispanica L.) Seeds
Walid
Moghith
This study was conducted at the Lab of Desert Research Center, during the two successive seasons of 2016/2017 and 2017/2018. The aim of this study was to investigate the tolerance of Salvia hispanica L. seeds germinated in filter paper or grown in sandy soil to water salinity irrigation. The seeds were irrigated (till 100% of field capacity) every two days using tap water (control, 0.42 dS m-1) or saline water containing of NaCl at a concentration of 2.34, 3.13, 3.91 and 4.69 dS m-1. Saline water was used from the beginning of seed sowing till full germination (from 10-17 days). The recorded results indicated that filter paper medium is more effective in reducing the unfavorable effects of salinity on the most of the studied germination parameters than sand. Raising the salt concentration in irrigation water up to 4.69 dS m-1 decreased the most of germination parameters (germination percentage, germination index and mean germination rate of chia seeds). The highest values of above mentioned parameters were gained by the combination of 0.42 dS m-1 concentration (control), especially those germinated on filter paper, followed descendingly by 2.34 dS m-1 concentration with the filter paper growing medium in both seasons. Also, the highest mean of daily germination and germination value were recorded by grown chia seed in filter paper and irrigated with saline water at 2.34 dS m-1 in 1st and 2nd seasons, while seeds grown in the same above mentioned medium and irrigated with saline water at 2.34 dS m-1 scored the highest peak value for germination in both seasons. Furthermore the highest values of coefficient of variation of germination time were gained by the combination treatments of the highest salinity concentration 4.69 dS m-1 with the filter paper growing medium in both seasons. On the other hand the combination of growing sand medium and irrigation with saline water at 3.91 dS m-1 concentration showed to be the most effective one for producing the highest mean germination time, time to 50 % germination and time to 90 % germination of chia seeds in both seasons. Conclusively, using filter paper as the germination medium produced the best germination parameters at the lowest salinity level 0.42 dS m-1. On the other hand, the filter paper growing medium reduced, to some extent, the negative effect of salinity on chia seed germination parameters.

Role of the Saw-Toothed Grain Beetle, Oryzaephilus Surinamensis (l.) in Date Palm Fruits Decay at Different Temperatures with Special References to its Thermal Requirements Estimation.
Results showed that lab. Condition and 25ºC were the of degrees of temperatures where decay and prevailing of the saw-toothed grain beetle occurred. The rearing of this insect on 40ºC caused mortality of all adults and no adult emergence occurred, hence this degree of temperature prevented decay of dates. Also, the effect of four constant temperatures (20, 25, 30 and 35 ºC) on developmental rates of different stages ofOryzaephilus surinamensis (L.)was studied. The time required for development of different stages increased as the temperature decreased. The average thermal requirements needed for completing the development was 99.7, 559.8, 207.8 and 843.4 degree days for eggs, larvae, pupae and development period respectively.

Two field trials were carried out in west Nubaria district, throughout two successive seasons of 2016/2017 – 2017/2018 to evaluate multiple strategies based on reducing the interval between seeding and seedling emergence, by increasing the speed of germination and seedling emergence to offer the most important escape strategy from soil-borne pathogens, the acceleration of germination and plant emergence and sometimes the improvement of seed viability and the acceleration of seedling growth was done by means of what so called EPD (Early Plant Development or fast initial growth) under protection using certain nematicides. Along with those field trials, pot experiment was done at outdoor for 60 days to assess host suitability (resistance) designations of studied varieties i.e. Beta vulgaris subsp < em>. Vulgaris, Sahar var. and Helsinki to root-knot nematode, Meloidogyne incognita. Experimental design was a factorial arranged split-split plot with variety as main plot, plowing depth as split plot in the form of strip-plot arrangement of six treatments and treatment as split-split with four replicates was used. Quantitative scheme for assignment of Canto-Saenz’s host suitability for root-knot nematode showed that sugarbeet variety, Helsinki is tolerant and Sahar variety is susceptible. Evaluated treatments i.e. strategies were varied combinations their components consisted from EPD, Abamectin, Oxamyl 10% G and Nemastop and were compared with control treatment. Analysis of variance for the combined data of the studied two seasons significantly at P ≤ 0.05 marked out the effect of various treatments. Studied Treatments impact individually or in combinations on root-knot nematode parameters, as nematodes number/g soil, knot disease severity % and drop rate % results indicated that sugarbeet variety Helsinki overcame Sahar variety positively for the abovementioned parameters; also, 30 cm-plowing depth outperformed the other two depths in the same issues. Managements treatments distinctly revealed that (EPD + Nemastop), (Nemastop) and (EPD) achieved the best results to reduce all studied root-knot nematode parameters Most likely with a plowing depth of 30 cm. Individual treatments showed that at the level of variety, monogerm Helsinki outperformed polygerm variety, Sahar in all abovementioned parameters. At plowing depth level, 30 cm-plowing depth was mostly had superior positive effect on all recorders. At the level of treatments, (EPD + Nemastop) had a distinguish effect on root and sugar yield per fed., sugarbeet variety, Helsinki overcome Sahar variety. Also, 30 cm-plowing depth had the lead in achieving preferred results, as well treatments (EPD + Nemastop), (Nemastop) and (EPD). Interactions of combined treatment as well showed distinguished results for those parameters mentioned above as combined treatments implied one of those distinguish individuals. Interaction effect of combined treatments got promising results as they implied any of individual treatment that previously showed positive results concerning the same nematode parameters.

Gad
Rady
The present study was conducted during two experienced growing seasons of 2016/ 17 and 2017/ 18 at West Nubaria Sector. The experiments were designed to evaluate certain management strategies for root-knot nematode, Meloidogyne incognita. The main studied factors were plowing depth and control treatment; there were three plowing depths and six treatments. Experimental design was a split plot randomized complete block design, split plot with plowing depth as main plot, strip-plot arrangement and treatments as subplot with four replicates. Single treatments and combinations of Abamectin, Nemastop, Mocap 10% G and potassium-based polymer yet were compared with untreated control. Analysis of variance for the combined data of the studied seasons significantly at P ≤ 0.05 cleared out the effect of various treatments. Management strategy efficacy %., denoted that 30 cm-plowing depth scored the best At level of control treatments, the lead was due to (Nemastop + Polymers) followed by Polymers followed with (Abamectin + Polymers). Interaction effects on efficacy % revealed that the best results obtained were with 30 cm- plowing depth × (Abamectin + Polymers) followed by the same depth with Polymers followed by 30 cm- plowing depth with (Nemastop + Polymers). All treatments achieved positive impacts on root-knot nematode and sugar beet yield parameters when interacted with each other under deficit irrigation (DI) to level of 75 % of Irrigation water requirements (IWR)
Plowing depth of 30 cm achieved the most promising results for number of plants after thinning, at harvest and losses percentages in number of plants/ fed. in sugar beet field. Also, plowing depth of 30 cm scored the highest values for root yield and extractable white sugar yield. 50 cm-plowing depth recorded the best value for purity percentage followed by depth 30 cm. Plowing depths of 30 cm and 50 cm showed the lowest values for sodium (Na) percentage and potassium (K) percentage. Plowing depth of 50 cm scored the highest value for extractable white sugar percentage (ZB %) , with significant difference between it and the two other plowing depths of 30 and 40 cm at P ≤ 0.05. The lowest number for root- knot nematodes number/g soil as affected by plowing depth was recorded at plowing depth of 30 and 50 cm. also, the lowest record for disease severity % recorded was for plowing depth of 30 and 50 cm. Drop rate % is another indicator for efficiency of management strategy. The most excellent drop rate % was achieved by plowing depth 30 cm,
consequently, the study recommends plowing depth of 30 cm and adequate nematicide seed treatments under deficit irrigation (DI) of 75 % water requirement is best combination to increase water use efficiency (WUE) as well as to improve the efficiency of modern integrated management strategies to control M. incognita in sugar beet infected fieldswithout serious effects on crop performance which eventually results in augmented yield.

Toxicity of Some Plant Oil Nanoemulsions to Black Cutworm, Agrotis ipsilon Hufnagel (Lepidoptera: Noctuidae)
The insecticidal activity of some botanical oils on the black cutworm, Agrotis ipsilon Hufnagel (Lepidoptera: Noctuidae) was evaluated in laboratory assays. Oils of jojoba, garlic, and pumpkin plants were prepared in the form of nanoemulsion. Second and fourth instars larvae were treated with original oils and their nanoemulsions via the leaf dipping technique. The results revealed that 5% nanoemulsion oils were significantly more effective than original forms. The average size of the nanoparticles of effective nanoemulsion oils was 185.4, 362.9, and. 281.5 nm for jojoba, garlic, and pumpkin, respectively. The obtained data indicated the nanoemulsion of jojoba oil was the most effective against 2nd and 4th instars larvae, causing 100% and 60% mortality after 2 days of the treatment at concentration of 5% for 2nd and 4th instars larvae, respectively. It was concluded that the formulated nanoemulsion of these botanical oils can be used as an effective alternative to commercial pesticide formulations to control A. ipsilon larvae.

Effect of Magnetic Iron and Potassium Humate on Some Flowering and Fruiting Characteristics of "Aggizi" Olive Trees Grown under Salt Stress Conditions in South Sinai
M.G.
Abo-Gabien
The use of soil amelioration agents is an important physiological method that improves plant tolerance to salt stress. The aim of this research is to examine the soil application of magnetic iron (MI) and/or potassium humate (KH) to mitigate the effect of salinity on the flowering and fruiting characteristics of ’Aggizi’ olive trees. Ten-year-old trees grown in sandy loam soil were treated with four levels of MI (0, 500, 750 and 1000 g / tree) and KH (0, 50, 75 and 100 g / tree) as a single dose during soil preparation on 1 December in both seasons. The result showed that the individual application of each anti-salt stress substance improved the flowering and fruiting characteristics and resulted in the higher number of inflorescence per shoot, fruit set percentage, fruit weight, fruit diameters, flesh thickness and tree yield compared to the control plants. The dual interaction of MI with KH was significant for all of the studied attributes. The interaction of the highest levels of MI (750 or 1000 g per tree) and KH (75 or 100 g per tree) improved the flowering and fruiting characteristics of “Aggizi “olive trees. These results suggest that anti-salt stress substances may be useful methods for use in arid and semi-arid regions to enhance salt tolerance in olives.

Partial Substitution of Chemical Fertilization of Dutch Fennel Plant (Foeniculum vulgare Mill.) by Bio Fertilization
Mustafa
Mady
The present work was carried out on Dutch fennel plant strain during the two successive seasons of 2017/2018 and 2018/2019 at Baloza Research Station, North Sinai Governorate, Egypt. The aim of the work was to evaluate the effect of bio-fertilizer applications as partial replacement for chemical fertilization on vegetative growth, fruits yield, essential oil productivity and its main components as well as chemical constituents of Dutch fennel plants under Sinai conditions. The experiment was planned in a randomized complete blocks design (RCBD) with three replications for each treatment. Treatments were the combination of five fertilization levels (full recommended dose of NPK only, 75, 50, 25% of the recommended NPK plus bio-fertilizers and bio-fertilizers only). The results showed that application of T2 (75% of the recommended NPK plus bio-fertilizers) increased vegetative growth measurements (plant height, number of branches/plant, herb fresh weight/plant and herb dry weight/plant), yield parameters (number of umbels/plant, weight of 1000 seed, seed yield/plant and seed yield/feddan), maximized the essential oil percentage and yield compared to other treatments. However, the lowest values of vegetative growth measurements, yield parameters and essential oil productivity were obtained with plants treated by T5 (bio-fertilizers only). As general, the major chemical constituents of Dutch fennel essential oil were trans-anethole and estragole.

Interaction Effect between the Applied Phosphorus and Selenium with Time on Their Availability in Three Different Soil Types.
Heba, A. M.
Abou-Zaid
A laboratory experiment was conducted to evaluate the interaction effect of phosphorus and selenium application rates on their availability in three different soil types with time. The soil samples were collected from the surface layers "0-30 cm" of three different sites. Four levels from Se were used as followed 0.0 – 0.5 - 1.0 and 2.0 mg Se kg -1 soil as sodium selenate while P was used as mono super phosphate at rates of 0.0 – 3.225 – 6.45 and 12.9 mg P kg-1 soil and they were incubated with soil for one month. Results revealed a positive and significant correlation between Se and P application rates as well as time of incubation on soil available Se; where soil available Se content was increased with increasing the application rate of Se especially when P was also added at high rates as time of incubation was passed. The highest soil available Se values were obtained when Se and P were added at rates of 2 and 12.9 mg kg-1 soil, respectively especially in the case of soil 3 (clayey soil). Results also showed that soil available phosphorus was positively but not significant affected with increasing the application level of both Se and P, but it was negatively affected as the time of incubation was increased.

Soil Quality as Indicated by Physical and Chemical Properties in Some Tanta Areas, Nile Delta, Egypt Using Remote Sensing and GIS Techniques.
Maha A. M.
Abdel-razek
The present study aimed at assessing the physical and chemical quality of the soils in Tanta area of El-Gharbia Governorate, Egypt. Its area is 33760 ha (located between longitudes 30°45′ and 31°20′ Е and latitudes 30°35′ and 31°15′ N). The mapping units in the study area: overflow basin (OB), high river terrace (RT1), moderate river terrace (RT2), low river terrace (RT3). Nine soil profiles were selected to represent Tanta area soils in addition to 18 soil samples. Twelve physio-chemical parameters which used to assess soil quality were chosen to evaluate soil quality including; texture (T), drainage (D), effective depth (P), parent materials (M), rock fragment (R), slope gradient (S), hydraulic conductivity (H), water holding capacity (W), electrical conductivity (C), soil reaction (O), exchangeable sodium percentage (G) and calcium carbonate (N). Results showed that Tanta district could be classified into one class according to the physical quality measures (moderate), while results of chemical quality index revealed two classes (high and moderate). Over 44% of the soil of Tanta area is of moderate soil quality index while 55.51% is of low soil quality index according to both physical and chemical parameters. The low soil quality dominates the areas characterized by shallow depth, poor drainage and hydraulic conductivity. The results demonstrated that management of soil practices should be carefully associated with soil characteristics.

Mostafa A.
Mostafa
Availability of sufficient and accurate spatial data concerning land resources is a pillar for sustainable agricultural development. The current work was aimed at using remote sensing (RS) and geostatistical analysis tools within geographic information system (GIS) to map land capability and crop suitability for an area in the Qattara Depressing, Western Desert of Egypt, located east of the Qattara Depression between latitude 30° 10' 4" to 30° 20' 57" N and longitude 28° 32' 26" to 28° 52' 10" E, covering 630 km2 (63000 ha). Thirty-seven soil profiles were dug to 150 cm. Soil samples were collected from different horizons and analyzed for their main properties. Applied System for Land Evaluation (ASLE) software was used to assess land capability and land suitability. Landforms include sand sheets, sand dunes, depressions, sabkha and water bodies. The 74.69% of the soils are"poor" (C4), 0.47% are"good" (C2), 11.68% are"fair" (C3), 11.12% are"very poor" (C5), and 0.47% are"non-agricultural" (C6). Soil texture, salinity and alkalinity are the main limiting factors. Classes for suitability (considering 22 crops) are highly suitable (S1), suitable (S2), moderately suitable (S3), marginally suitable (S4), currently not-suitable (N1), and potentially not-suitable (N2) for 22 crops. The most recommended crops are date palm and tomatoes. The studied soils require precise management practices to be promising for agricultural expansion.

Treatments were the combination of seven fertilization levels (full recommended dose of NPK only (100%NPK) T1, 75% NPK + 25% organic (compost) T2, 50% of NPK+ 50% organic (compost) T3, 25% of NPK+ 75% organic (compost) T4, T5 ( T2+ Bio- NPK), T6 ( T3+ Bio- NPK) and T7 (T4+ Bio- NPK). The result indicated that, application of T1 (100% of chemical NPK) caused a significant increasing in the rate of length, diameter, number of leaves, leaf area, transplant leaves area, fresh and dry weight of leaves, Leaf dry matter percentage. Likewise, T1 increased the nutrient status i.e. (N, P, K, Mg, Ca, Fe, Mn, Zn), as well as improved the leaf photosynthetic pigments. Followed by T5 75% NPK + 25% organic (compost) + Bio- NPK. By contrast, T4 25% of NPK+ 75% organic (compost) led to the lowest values compared other treatments in both season.

Neven
Basiouny
A pot experiment was conducted at the Nursery of the Experimental Station of the Horticultural Research Institute, Agriculture Research Center at Giza, Egypt, during the two growing successive seasons of 2017 and 2018. This work aimed to investigate the response of Swietenia mahagoni seedlings grown under irrigation water salinity stress to soil application of different concentrations of sulfur as well as foliar application of mono potassium phosphate (KH2 PO4) and foliar application of putrescine {NH2 (CH2)4 NH2 (1,4 diaminobutane or butanediamine)}. Survival percentage of S. mahagoni seedling was 100 % at salinity level of 4.69 dS m-1. As salinity level increasing to 6.25 dS m-1 survival % decreased to (64.30 and 69.60 %) in both seasons, respectively. All growth parameters, i.e. (height of plant, diameter of stem, number of leaves per plant, fresh and dry weight of leaves and roots, and length of root) decreased as the concentrations of saline water irrigation increased. Whereas, the highest values of free proline content, was gained by the highest concentration of saline water irrigation (9.38 dS m-1). The most positive effect of combination treatments on height of plant, nitrogen percentage, and total chlorophyll in leaves were T10 (putrescine at 300 mg/L) with salinity level of 4.69, dS m-1. However, the most positive effect of combination treatments on diameter of stem, number of leaves, fresh and dry weight of leaves and roots, and length of root were T7 (monopotassium phosphate at 3g/L) with increasing salinity level to 4.69 dS m-1, also, due to significantly increased phosphorus, and potassium percentage in leaves. It can be concluded that salinity level of 4.69 dS m-1 with putrescine at 300 mg/L or monopotassium phosphate at 3g/L were the best for improving vegetative growth, and chemical compositions of S. mahagoni seedling.

Effect of Adding Phosphorous With Organic Matter on Wheat Production under Sandy Soil Conditions
Essmat
Nofal
Wheat is one of the most important strategic crops in terms of food security. Phosphorus (P) is an essential macronutrient being required by plants in relatively large amounts. The availability of phosphorus in soils is affected by several factors such as the decomposition of organic matter in the soil. Higher soil organic matter concentrations have been proved to enhance the yield and yield components of cereals. The present study, therefore, aims at studying the effect of adding phosphorus and farmyard manure as a source of organic matter on the yield of wheat plants grown under sandy soils conditions. To fulfill the objective of the study a field experiment was conducted at Balouza station in North Sinai, Desert Land Research Center, in the winter season 2018-2019. The design of the experiment was a factorial randomized complete block design with two factors in three replicates. The experimental site was divided into two main plots. Each main plot was divided into three subplots. Organic manure was added to the first half of the main plots at a rate of 25 kg/plot, O1 (25 ton/ hectare) and at a rate of 50 kg/plot O2 (50 ton/hectare) to the other half. Superphosphate was added at three rates i.e P1 = 840 kg/hectare superphosphate fertilizer (6.8 % P). as soil application; P2= 630 kg/hectare superphosphate fertilizer as soil application + 210 kg/hectare superphosphate fertilizer as foliar application and P3 = 420 kg/hectare superphosphate fertilizer as soil application + 420 kg/hectare superphosphate fertilizer as foliar application. Each treatment was replicated three times. The foliar application was done as the supernatant of soaked superphosphate fertilizer.
Wheat grains (cv. Giza 168) was cultivated in 23 November 2018. Irrigation was done with Al-Salam Canal water. At maturity (9/5/2019) wheat plants were harvested and separated into grains and straw. The grain yield and the straw yield was recorded. Subsamples of wheat straw and grains were ground. A 0.5 gram samples was digested using a mixture of sulphuric and perchloric acids (1:1 v/v). Digests were diluted with distilled water up to a 100 ml and analyzed for N, P and K concentration. The obtained results could be summarized as follows: There was a significant difference in grain yield due to the application of organic manure at increased rate from O1 to O2. Also, a significant difference in grain yield occurred due to the application of P fertilizer at increased rate from P1 to P3, and the rate P2 gave the highest increase. The interaction effect between the organic manure rate and P fertilizer rate was significant, where a significant difference in grain yield occurred between P2 application and the grain yield obtained due the application of P1 and P3 under the application of organic manure at the rate O1. Under the application of organic manure at the rate O2 significant difference in wheat grain yield occurred between P1,P2 and P3 , however, the highest grain yield was obtained under the application of P at the rate P2 with the application of the organic manure at the rate O2.
There was a significant difference in straw yield obtained under the application of organic manure at increased and the highest straw yield was obtained at the rate O2. On the other hand, application of P fertilizer at increased rate significantly increased straw yield from P1application up to P2 application. However, increasing P application from P2 up to P3 decreased wheat straw yield. There was a significant interaction between the organic manure and P fertilizer on the straw yield of wheat, where a significant difference occurred between the straw yield obtained due to the application of P at increased rate from P1 up to P3 under the application of organic manure at the rates O1(25 ton/hectare) and O2 (50 ton/hectare). However the highest straw yield was obtained under the application of P fertilizer at the rate P2 and the application of organic manure at the rate O2.
Application of P fertilizer at increased rate under the application of organic manure at increased rate, increased the concentration of N, P and K in both of the straw and grains of wheat plants and the highest increase was obtained under the application of P fertilizer at the rate P2 and the application of organic manure at the rate O2.

Economics of Production and Evaluation of Rabbit Production Farms in Qaliubiya Governorate
Amira
Elhabaa
Animal production is considered one of the main activities of the agricultural sector, due to the fact that it is the primary source of animal protein, which is a necessary element needed by humans. Also, poultry production is one of the main aspects of the sources of income from animal production, and rabbit meat is considered a suitable alternative to meat for the consumer, as it reached The value of meat production from rabbits is about 2.5 billion pounds, representing about 0.50%, 1.33% and 5.34% of the value of agricultural production.
The problem of the study was the shortage of animal protein suffered by most of the population of Egypt, which leads to the trend towards the development of livestock, which includes rabbit production projects as a solution to the meat crisis in Egypt, by increasing production, And increase the productivity of existing farms, and raise their economic efficiency, due to the enormous economic and productive advantages they carry. The most important research findings were as follows:
By studying the production functions of licensed and unlicensed rabbit production farms in the double logarithmic form and by estimating the return on production capacity by calculating the elasticity coefficient of total production of the most important elements affecting rabbit production, it amounted to about 1.3, 1.02 for licensed and unlicensed farms, which indicates an increased production capacity (first stage of Production according to the law of diminishing returns) Which necessitates increasing production and operating the production elements more efficiently to reach the economic stage, and the results of the financial and economic evaluation of these farms were as follows: Productive and economical of the project, The payback period was about 1.20, 1.07 years for both licensed and unlicensed farmers, and the rate of return on investment was about 1.52, 1.38 for both licensed and unlicensed farms, and the profitability index was about 2.20, 2.07, which reflects the profitability of licensed and unlicensed rabbit farms, respectively. Thus, the study recommends that attention be paid to rabbit breeding and production projects, given the profitability of these projects, the speed of the capital cycle, and work to increase the productivity of existing farms to increase investor income and to bridge the nutritional gap from animal protein in Egypt.

Measuring the Impact of International Variables on Intra-Arab Agricultural Trade Using the Gravity Model
MAHMOUD
ELHABBAQ
The Arab countries are highly dependent on non-Arab countries for their food needs, despite the fact that the Arab world occupies great strategic importance among the countries of the world because of its geographical location, its vast area and its population. It extends from the Atlantic Ocean to the west, The Arab Sea in the east and the Arabian Sea to the south of Turkey and the Mediterranean Sea. It covers an area of about 13.5 million square kilometers, of which 22% is located in Asia and 78% in Africa. The Arab coasts are about 22.8 thousand km. This is an indicator of the diversity of natural and economic resources of this region. Therefore, the study will focus on the economic potentials available in the Arab world and the extent of their diversity, thus increasing the opportunities and possibilities of Arab integration, especially in Arab agricultural integration. In the present circumstances, the economies of the Arab countries as developing countries face a new economic environment characterized by changes in economic structures and relations Therefore, it is necessary to shed light on the study of the conditions of Arab agricultural, agricultural and intra-agricultural trade, and the impact of contemporary international variables on them, so that proposals or perceptions of how to achieve Arab agricultural integration can be developed in light of the available possibilities.

An Economic Study to Estimate the Impact of Inflation on the Performance of the Most Important Productive Sectors in the Arab World
Ahmed Abd El- Salam
Jagheef Al-Nasiri
The results of the research indicated that the contribution of the agricultural sector to the structure of Arab GDP during the period (2010, 2015-2017) shows that it contributes about 6.2%, 5.8%, 6% and 5.6% during the mentioned period, while the contribution of the commodity sector reached 57.2%. Total services sectors were estimated at 42.1%, 52%, 54.1% and 51.9% for the same periods. Given the harsh conditions that Iraq has gone through, it has been unable to find mechanisms to control market prices that determine the levels of hyperinflation, which now threatens the real income levels of the individual, despite the adoption of monetary policy unique in the world through its hegemony and in absolute form and governed by exchange rates Foreign through the daily central bank auction. Where the statistics of the Iraqi Ministry of Planning for another rise in inflation rates, witnessed in 2017 and by 0.8 percent from 2016 rates, and the general index is one of the most used indicators in measuring inflation in Iraq, reflecting the change in the prices of goods and services to consumers. The index monitors 416 goods and services collected by the Central Bureau of Statistics monthly from the cities of Iraq. The problem of inflation is a phenomenon faced by most countries in the world adopted a free market system, but the causes of inflation and types vary from one country to another. There is an increase in the value of a specific commodity, but it is temporary in a season or occasion that will disappear after a short period. There is a real inflation problem, although its rates have declined over the past decade compared to years before 2003. The drop in gross domestic product (GDP) except oil is so low that it does not exceed $ 35 million. For vital sectors in the Economy, such as energy, fuel, transportation, and other service sectors. Inflation has increased the burdens of the Iraqi family, because families living without a specific financial resource have reduced their consumption and rearranged their consumption priorities because they are unable to cover the increase in prices resulting from the continuous rise in the prices of some commodities, especially oil derivatives. The results of the research indicate that there is a relationship of inflation rate and economic variables, the GDP of current and real prices and the real exchange rate

The Current Status of the Role of the Most Important Microfinance Institutions in Rural Egypt
Asmahan Hussein
AbdElhady
Program being implemented by the Egyptian Small and micro-agricultural enterprises are an important component of the economic reform government to break the economic downturn.
The state faces many problems, especially in recent times, where the problem of unemployment and low personal incomes has become one of the most pressing problems in the Egyptian economy. The elements of production in order to produce goods and services, therefore, some economists believe that small and micro enterprises are the only way to solve these problems plaguing the country.
The main objective of this research was to identify the role of the most important microfinance institutions in the Egyptian countryside by studying the following sub-objectives: Evolution of the value of loans disbursed from the Local Development Fund, estimating the disbursement of small and micro enterprises according to the geographical scope during the period 2009-2019, determining the number of Legislations, Women's Projects, Number of Beneficiaries and Job Opportunities.

Ibrahim Mahmoud
Mohammed Murad
The aim of reducing the quantitative and qualitative losses the most important Egyptian exports and imports while avoiding health, environmental, marketing and economic problems is one of the main axes of the improvement of the local food situation. Due to the lack of some traditional methods of conservation, there has been an international and local approach to using conservation technology to prevent this deficiency and the importance of improving the application Commercialization of this technique was important to conduct such a study of technical feasibility, marketing, financial and national, where the study included three sections.
The first section deals with the technical possibilities of the use of food irradiation technology in the preservation of some exports and food imports (wheat, maize, legumes, potatoes, onions, garlic, fruits, citrus, red meat). In the second section, the preliminary indicators for the application of irradiation technology in the preservation of some exports and food imports were sought. The study indicated that the expected quantity is saved to the equivalent of 933 thousand tons per year with irradiated dose of 1 kg. In the third section, the financial analysis was carried out, including the determination of investment expenditure, labor cost, annual operating specifications, pre-operating expenses, annual depreciation, total annual costs (56.5, 0.79, 4.16, 11.05, 2.53) 103 L.E The price of irradiation was more than 0.5% of the market price of any of the foods studied. The commercial profitability of irradiation has been evaluated. Save exports and imports and use cash flow tables where a The results of the analysis showed that the internal rate of return is 27%, 21%, while the Pay Back period is 3.4 years, 4.4 years in both basic analysis and sensitivity analysis. The expected returns to the national income were analyzed as a result of keeping some exports and food imports using technology Irradiation as a result of reduction of losses and avoid the health and environmental problems of traditional conservation methods. The study showed that the expected return to income amounted to 602 million pounds annually.

The Economic Evaluation of the Use of Biotechnology Technology and Applied To the Productivity of Wheat under the Conditions of Qantara East
Biotechnology is an integrated production system that allows the improvement of the ecological and economic system of agricultural soil, as well as increasing the diversity and biological activity of soil microbes. Application of biotechnological technology includes the use of bio-fertilizers, which have become the most effective and reliable alternative to mineral fertilizers and their use in agriculture. The problem of the study is that the traditional agriculture of the wheat crop in the new lands and the use of chemical fertilizers did not achieve the optimal production of the wheat crop with the high costs of agriculture from the requirements of fertilization and irrigation, which is reflected in the reduction of productivity of feddan. Fertilization of the wheat crop and proved its high ability to increase the productivity of feddan and resistance to diseases affecting the wheat crop has been proved in many research studies in the form of master and doctoral dissertations in each of the universities and research centers, and considered Economic conditions has become an urgent need to increase the productivity of wheat to fill the food gap.
Therefore, the study aims to estimate the production capacity of the wheat crop in Egypt and its relation to food security, the use of bio fertilizers in fertilizing the wheat crop and its quality study in increasing the yield of wheat compared to mineral and organic fertilizers.
It was found that the average farm price of wheat crop is about 129, 215.83 and 355.17 pounds / ton during the periods (2000-2005), (2006-2011) and (2012-2017) respectively, with an average of 233.33 LE / ton during the study period (2000-2017). The average value of the total wheat crop income is about 2943.6, 5434.33 and 7968 LE / feddan as an average during the periods (2000-2005), (2006-2011) and (2012-2017) respectively, -2017) estimated at 5448.64 pounds / acre.
It was found that the average total cost of wheat crop during the period 2000-2005, 2006-2011 and 2012-2017 amounts to about 1202.75, 2156 and 5158.17 pounds / fed respectively, with an average of 2838.97 LE / feddan during the study period (2000-2017). The average net yield of the wheat crop during the periods 2000-2005, 2006-2011 and 2012-2017 is about 1537, 2230.67 and 2578.17 LE / fed, and the average for the study period (2000-2017) is estimated About 2115,28 pounds / acres
It was found that the average yield on the spent pound is about 0.67, 0.7 and 0.74 pounds during the periods (2000-2005), (2006-2011) and (2012-2017) for each of them respectively, with an average of about 0, 71 pounds during the study period (2000-2017). And the average yield on the pound per month for the wheat crop during the periods (2000-2005), (2006-2011) and (2012-2017) is about 193.07 and 467.69 and 429.69 pounds / month respectively, and on average Year estimated at 363.48 LE / month during the study period (2000-2017).
The study showed that the food gap of wheat tends to increase around the average of 5841 thousand tons, with a minimum of 2409 thousand tons in 2005, and a maximum of about 11079 thousand tons in 2017. While the average self-sufficiency rate of wheat was 60.3% during the study period. It ranged from a low of 47.89% in 2010 to a decrease of 12.41% from the average gap during the same period. The highest increase was about 77.17% in 2005, an increase of about 16.87% compared to the annual average during the same period.

The Effect of Unconventional Diets on the Production of Red Meat in Egypt
Mohamed Kamal
Eldin Hassan
The problem of animal protein deficiency is one of the most important problems facing the improvement of the food level in developing countries. The problem of research is the inability of the productive capacity of the feed resources of farm animals in Egyptian agriculture to cover the animal needs of these resources, and this problem is exacerbated due to Egypt's lack of animal feed materials in addition to the waste in agricultural products and by-products of some field crops. Get rid of them in negative ways. The research aims to study the current production status of fattening livestock in the Arab Republic of Egypt in general as well as the current production situation of traditional and non-traditional animal feed and study the size of the animal feed gap with the study of the impact of non-traditional feed on the production of fattening livestock. With regard to the study of the production situation of red meat in Egypt during the average period (2000-2017) it is clear that the minimum production of meat in Egypt reached about 696 thousand tons in 2001, while the maximum reached about 990 thousand tons in 2012, an increase of about 294 thousand tons The minimum level dropped to about 972 thousand tons in 2017, while the average annual production of red meat in Egypt during the period (2000-2017) about 904 thousand tons annually. The study of the local production of concentrated feed during the period (2000-2017) showed that it ranged between increase and decrease as the minimum amount reached about 5526 thousand tons during 2004, which represents about 6.1% of the total feed production for the same year, while the maximum amount was about 11309 thousand tons in 2015, representing about 14.8% of the production of feed for the same year, an increase of about 8.7% over 2004. The overall average production of concentrated feed in Egypt about 8587 thousand tons, representing about 9.84% in terms of the relative importance of the total production Feed in Egypt.

Economic Evaluation of the Project of Cucumber Production in Agricultural Produce In Dakahlia Governorate
Projects of various sizes and types are considered the main and fundamental pillars of development plans, through the implementation of various projects in the sectors of the national economy. Economic development is achieved and economic growth in various countries depends on the safety of investment decisions in projects which constitute economic development programs. SMEs are an important component of the Egyptian government's economic reform and liberalization program, but they have not been adequately reflected in job creation, productivity improvement and income generation. While the economic transition has shifted the burden of the production process from the Government to the private sector, with growing population growth rates and growing economic needs, a great number of new jobs and increased production are required. Small and medium enterprises represent more than 99% of Egypt's private non-agricultural enterprises and contribute almost "to the provision of nearly three-quarters of the jobs provided by this sector, although small and medium enterprises suffer from inadequate resources and inefficient resources. Efforts should be intensified to develop these facilities and provide the necessary services such as developing the skills of those involved and developing the transfer of technology used in these projects as well as assisting the enterprises.

Effect of Spraying Dolomite Nano-Particles on Growth, Flowering and Fruit Setting of Picual Olive (Olea europaea L.) Cultivar under Water Stress Conditions
I. M.
Dobiea
Water stress “an abiotic stress” is one of the main challenges which constrain olive cultivation in reclaimed area in Egypt. It can impair the growth and production performance of olives. Many investigations recommended spraying dolomite nano-particles "Lithovit® fertilizer” to reduce the effect of water stress. We believe that we have designed an innovative solution to follow up the effect of spraying dolomite nano-particles (Ca CO3 & Mg CO3) on olive trees which exposure to different irrigation levels. Four concentrations of dolomite nano-particles were sprayed on olive (Olea europaea var. Picual) trees (0, 2, 4 and 6 g/L) under three irrigation levels (50, 75 and 100% of evapotranspiration for crop “ETc”) during 2017, 2018 seasons. Strong evidence of irrigation at 75% of ETc was found on olive growth, flowering and fruit setting. It was the best irrigation level to balance between vegetative growth and blooming. Moreover, there were significant variations between spraying dolomite nano-particles at 2 g/L and other concentrations on flowering and fruit setting. Furthermore, the interaction between spraying dolomite nano-particles and irrigation levels cleared that spraying dolomite nano-particles at 2 g/L and irrigation at 75% of ETc enhanced flowering and fruit setting.
