In order to study the effect of phosphorus fertilization rates and microelements spraying treatments on plant characteristics and yield traits as well as some seed chemical properties of faba bean varieties, an experiment was conducted in two successive growing seasons of 2018/2019 and 2019/2020 in the Farm of Agricultural Research and the Experimental Center of Faculty of Agriculture at Moshtohor, (Toukh Directorate, Kalyubia Governorate) Benha Univ. Egypt. The experimental design was split-split plot in RCBD in three replications. Phosphorus fertilizer was considered as the main plot in three rates (0, 15 and 30 kg P<sub>2</sub>O<sub>5</sub>/fed). Four microelements spraying treatments [Tap water (control), Zn, Mn and mixed of Zn + Mn] were arranged in the sub plot. The sub-sub plots were occupied with three faba bean varieties (Giza 716, Nubaria 3 and Sakha 4). The obtained results could be outlined as following: Increasing phosphorus fertilizer rate from 0 to 30 kg P<sub>2</sub>O<sub>5</sub>/fed induced significantly increased most vegetative growth, yield attributes, yield and seed chemical properties of faba bean under study except, mid physiological maturity, height to 1<sup>st</sup> pod and phosphorus use efficiency were significantly decreased with rising phosphorus rates during the both seasons. The foliar spray by Zn and Mn as a single or in combination had significant effect on most faba bean traits under study compared with no microelements added during the both seasons. Faba bean plant treated with microelements foliar spray using Zn in combination with Mn was the most effective treatment for most faba bean characteristics in the both seasons. Mean performances of the investigated faba bean varieties for most faba bean traits under study were significant different during the both seasons. Faba bean variety Sakha 4 had higher values of chlorophyll content index at 85 DAS, plant height, height to 1<sup>st</sup> pod, No. of branches/plant, plant weight, No. of pods/plant, No. of seeds/plant, seed yield/plant, biological yield/fed, seed yield/fed, straw yield/fed, phosphors use efficiency, seed N content and seed protein yield/fed in the both seasons. While, Nubaria 3 variety significantly gave the maximum mean values in mid physiological maturity, harvest index and 100-seed weight in the both seasons, respectively. The first order interactions between treatments 30 kg P<sub>2</sub>O<sub>5</sub>/fed × Zn + Mn, 30 kg P<sub>2</sub>O<sub>5</sub>/fed × Sakha 4 and Zn + Mn × Sakha 4 as well as the second order interaction between treatments 30 kg P<sub>2</sub>O<sub>5</sub>/fed × Zn + Mn × Sakha 4 were significantly recorded the maximum seed yield/plant, biological yield/fed, seed yield/fed and straw yield/fed in the both seasons. Therefore, this study recommends that Sakha 4 variety treated by 30 P<sub>2</sub>O<sub>5</sub>/fed and mixed spraying with Zn 0.3 % + Mn 0.3 % in order to improve the production of faba bean under the condition of Toukh Directorate, Kalyubia Governorate, Egypt.

The aim of current study was to investigate the effects of the effect of genotype, season of birth and parity order on litter traits and body weight measurements of V-line and Moshtohor line (M-line) of rabbits. A total number of six thousand and three hundreds (6300 kits) offspring obtanid from these strains (100 sires and 300 dams) were used in this study. The body weight traits were recorded at 4, 8 and 12 weeks of age. Litter size at birth (LSB), Litter size at weaning at 28 days postnatal (LSW), Litter weight at birth (LWB), Litter weight at weaning at 28 days postnatal (LWW), Mortality rate and killing intervals. The effect of genotype showed that M-line revealed significant superiority (P<0.05) value of the body weight at all periods of estimation compared to V-line breeds. Also, the effect of season showed a significant (P < 0.05) change in the body weight at all periods of estimation due to season's effect. The heaviest live body weight was recorded for rabbits in springe, while the lowest live body weight was recorded in summer. Influence of parity indicated highly significant (P <0.05) differences in body weight in different intervals of age. The heaviest body weight was recorded in the third parity, while the lowest body weight was recorded in first parity. Likewise, the present study revealed a Highly significant (P < 0.05) difference were deleted in the litter size and at birth and weaning, litter weight at birth and at weaning between the different genotype, season and parity order. It can be concluded that M-line had the highest values of live body weight and litter traits compared to V-line rabbits. Current study finding suggest that M-line rabbits will be more productive and reproductive efficiency than V-line rabbit under Egyptian environmental conditions. So, the authors suggest that measuring of body weight and litter traits early ages could be a good and accurate indicator of growth performance in M-line.

The present work was aimed to study the effect of dietary L-arginine level, vitamin C, and their interaction between them on some productive performance of Matrouh laying hens during the summer season. A 4X3 factorial treatment arrangement was carried out including four levels of dietary L-Arg (0.0, 0.4, 0.8, and 1.2 g/kg diet) and three VC concentrations (0, 150, and 300 mg/kg diet). A total number of 108 Matrouh hens (Egyptian local strain) aged 64 weeks were randomly distributed into twelve treatment groups (three replicate each). The results obtained showed a significant (p < 0.05) effect in live body weight due to dietary L-Arg and VC supplementation at 72 weeks of age only. Significant (p < 0.05) differences were observed in feed intake and feed conversion ratio due to dietary L-Arg levels during all periods of estimation. Dietary L-Arg levels had significant (P<0.05) effects on the rate of egg prodction during the periods from 68-71 and 64-75 weeks of birds age. Significant (p < 0.05) differences were observed in egg weight due to dietary L-Arg and VC levels during all periods of estimation except at 72-75 weeks of age. Dietary L-Arg levels had significant (P<0.05) effect on egg mass during the periods from 68-71,72-75 and 64-75 weeks of bird’s age. The VC supplementation didn't have any significant effects on feed conversion ratio, egg production rate, egg weight, and egg mass. The interaction effects between dietary L-Arg and VC levels had a major influence (p < 0.05) on body weight, feed consumption, feed conversion ratio, egg production rate, egg weight and egg mass. In conclusion, it could be concluded that Matrouh laying hens supplemented diet with L-Arg at a level of 1.2 g or VC at a level of 300 mg/kg diet, seemed to be adequate to achieve the favorite results and is recommended.

A total number of 108 Matrouh hens and 36 cocks (Egyptian local strain) aged 64 weeks were randomly distributed into twelve treatment groups (three replicate each). The results obtained showed non-significant (p < 0.05) effect in fertility percentages due to dietary L-Arg or VC supplementation through all the experimental periods. The interaction effects between dietary L-Arg and VC levels had a major influence (p < 0.05) on fertility percentage. Dietary L-Arg levels had significant (P<0.05) effects on the hatchability percentages of total eggs set and fertile egg during all periods of estimation. The VC supplementation didn't have any significant effects on fertility and hatchability of fertile eggs percentage. The interaction effects between dietary L-Arg and VC levels had a major influence (p < 0.05) on the hatchability percentages of total eggs set during all the interval periods. In conclusion, it could be concluded that Matrouh laying hens supplemented diet with L-Arg at a level of 0.4 g and VC at a level of 150 mg/kg diet, seemed to be adequate to achieve the favorite results and is recommended.

The present study was aimed to investigate the effect of flock age, air pressure during incubation period and litter types on blood plasma constituents of broiler chicks. A total number of 600 one day old hatching chicks (ROSS 308) were taken randomly nearly a similar in live body weight were used in this study. Chicks were randomly divided into equal 12 groups in a 2×2×3 factorial arrangement experiment according to flock age (younger breeder flock 33 WKS and older breeder flock 43 WKS), air pressure (normal 100719 and high, 1011000 Pascal) and three litter types (wood shaving, plastic and sand). The results obtained showed that, broiler chicks produced from younger breeder flock recorded significantly (p < 0.001) the higher levels of plasma total protein (TP), albumin (A) and globulin (G). However, broiler chicks produced from older breeder flock found to be significantly decreased levels of plasma triglycerides, total cholesterol, low density lipoprotein, aspartate aminotransferase (AST), alanine aminotransferase (ALT) creatinine, uric acid and malondialdehyde (MDA).Broiler chicks produced from eggs incubated at high air pressure (HAP) showed significant(p < 0.001) the higher levels of plasma TP, A , G and MDA. While, chicks produced from eggs incubated at low air pressure decreased significantly the levels of plasma triglycerides, total cholesterol, LDL, AST, ALT, creatinine, uric acid and significantly increased plasma levels of high density lipoprotein (HDL) and glutathione peroxidase (GPX). Blood plasma constituents significantly varied due to the effect of litter type, it was found that broiler chicks raised on sand litter type showed the higher levels of plasma TP, A and G. While, the lower levels of plasma triglycerides, total cholesterol, LDL, AST, ALT, creatinine, uric acid, MDA and higher levels of HDL and GPX were found in broiler chicks raised on plastic (PL) litter type. According to the interaction between the studied factors, it could be concluded that the interaction between 43 WKS × HAP ×PL seemed to be adequate to achieve the favorable results of blood parameters.

The present study was aimed to investigate the effect of flock age (younger breeder flock 33 WKS and older breeder flock 43 WKS), air pressure during incubation period (low, 100719 (LAP) and high, 101000 (HAP) Pascal) and the type of litter on carcass characteristics and meat quality of broiler chicks. A total number of 600 one day old chicks (Ross 308) hatched from eggs of two flocks in different age (each of 300 chicks)were randomly chosen divided into two sub experimental groups according the air pressure of incubation conditions (each of 150 chicks), each sub-group divided into three sub-sub experimental groups were raised on floor house provided with litters of wood shaving, plastic and sand, respectively. This study was design as 2×2×3 factorial arrangement experiment. The results obtained showed that, broiler chicks produced from older breeder flock recorded the higher significant (p>0.05) absolute and relative weights of eviscerated carcass, giblets, total edible parts, protein, ash percentages, odor, color, elasticity and overall score of meat quality compared with younger ones. However broiler chicks produced from eggs incubated at HAP shoed the higher absolute and relative weights of eviscerated carcass, giblets, total edible parts, percentages of protein, fat pH, TVN, TPA and odor of meat. Broilers chicks raised on plastic (PL) litter type showed the higher values of absolute and relative weights of eviscerated carcass total edible parts, percentages of protein and ash, meat sensory evaluation and recorded the lowest microbial count of APC bacteria in meat and cecal . According to the interaction between the studied factors, it could be concluded that the broiler chicks hatched from eggs of the flock at age of 43 WK, incubated at HAP and raised on plastic litter type (43 WKS × HAP ×PL) seemed to be adequate to achieve the favorable results.

Two experiments were conducted to study the effect of adding soy-lecithin or xylanase to low-energy diet on broilers growth performance, nutrient digestibility, intestinal lipase enzyme activity and economical efficiency. A total number of 256 unsexed Cobb500 broiler chicks, a day old, were classified into two equal experiments, 128 chicks each (4 treatments × 4 replicates × 8chicks). In each experiment, chicks were divided into 4 groups as follows: - the 1<sup>st</sup> group fed basal diet and served as control which fed recommended energy diet, the 2<sup>nd</sup> group fed diet low (100 Kcal / kg diet) than recommendation (LED), the 3<sup>rd</sup> and 4<sup>th</sup> groups were fed 2<sup>nd</sup> diet added with 0.5g lecithin / kg diet or 1.0g lecithin / kg diet, respectively (EXP.1). While, chicks were fed 2<sup>nd</sup> diet supplemented with 0.1g xylanase / kg diet or 0.2g xylanase / kg diet, respectively (EXP.2). The growth trail was lasted at 35 days of age. The results revealed that, groups of LED + 0.5g lecithin (EXP.1) and LED + 0.2g xylanase (EXP.2) recorded significantly higher BWG and better FCR during overall period than control and LED groups. In both experiments, there is a gradual increase in EE% digestibility coefficient, intestinal lipase activity and economical efficiency by increasing the addition level of either soy-lecithin or xylanase.
It could be concluded that enriching low-energy diet with either 0.5g lecithin / kg diet or 0.2g xylanase / kg diet can improve broilers growth performance, intestinal lipase activity and enhanced economical net profit.

This study investigated the synergism relationship between lecithin (L) and xylanase (Xyl.) enzyme when applied to low dietary metabolizable energy (ME) on broilers carcass, meat quality and some blood parameters. 160 chicks randomly were allocated to 5 treatments, each of 32 birds (4 replicates of 8 birds each). The 1<sup>st</sup> group; chicks were fed basal diet without studied supplementation (control). In 2<sup>nd</sup> group, chicks were fed low ME diet (-150Kcal / kg lower than <strong>NRC,1994</strong> recommendation) and labeled as NC. In 3<sup>rd</sup>, 4<sup>th</sup> and 5<sup>th</sup> groups, chicks were fed NC supplied with 0.5g lecithin (NC + 0.5g L), 0.2g xylanase (NC + 0.2g Xyl) and 0.5g lecithin + 0.2g xylanase (NC +0.5g L + 0.2g Xyl), respectively. The growth trail lasted 35 days. The obtained results show that group of NC + 0.2g Xyl recorded significant increase in carcass %. The lowest meat total saturated fatty acids, total cholesterol, LDL and triglyceride were achieved for group of NC + 0.5g lecithin. Moreover, both NC + 0.5g L and NC +0.5g L + 0.2g Xyl recorded a significant decrease in plasma total cholesterol, triglycerides and LDL also, increase in plasma HDL compared to control.
In conclusion, addition of 0.5g lecithin alone or in a combination with 0.2g xylanase to broilers fed low-energy diet is more effective in carcass, meat quality and blood plasma lipid profile.

The present study aimed to distinguish light on the protective of <em>Moringa oleifera</em> seeds dried ethanolic extract on the toxicity in liver and kidney induced by acetamprid pesticide which widely produced and used for agricultural treatment in Egypt. Physico-chemical parameters and identification of fatty acid composition of <em>Moringa oleifera</em> seeds oil were elvaluated. In addition , the biological effects of bioactive components of seeds dried extract at concentration 200 mg/kg b.w. oil as additives into the diets on kidney and liver functions , lipid profile ,serum glucose levels , hematological parameters and histopatholgical examination of experimental rats were evaluated. From the obtained results , it could be noticed that the total phenolic acid , flavonoids and tannin contents in <em>Moringa oleifera</em> seeds of the dried ethanolic extract were 44.25±1.13 , 114.36±0.72 and 20.77±1.10 ug/g , respectively. Total antioxidant capacity of dried ethanolic extract of <em>Moringa oleifera</em> seeds was found to be 143.29±0.37 , 178.10±2.18 , 189.18±2.06 and 222.47±0.81 at 50 , 100 , 150 and 200 ug/ml . Also, the results showed that the <em>Moringa oleifera</em> (MO) seeds oil extract was dominated by the high percentage of total unsaturated fatty acid (80.29%) than its saturated (19.71%). On the other hand , the results showed that there were significant increasment of biochemical parameters such as serum urea and creatinine (as function of kidney) , as well as ALT and AST activity also albumin and total protein (as function of liver) , total cholesterol , triglyceride and serum glucose levels of the experimental rats. These values were found significantly decreased in all treatments rats fed diets containing MO seeds oils extract at dose of 200 mg /ml b.w. as compared with the group treated by acetampride (toxicated group).The results of the effects of MO seeds extract on hematological parameters of intoxicated rats caused significant decreasments in total white blood cells counts (WBCs) . While, MCV , MCH and MCHC were significantly unchanged relative to those of different from the control group but haemglobin (Hb) and red blood cells (RBCs) was increased.
Histopathological studies confirmed chemical analysis results. Finally, from the obtained results and histopathological examination , it could be concluded that the administration of MO seeds dried extract of ethanolic oils might improve the liver and kidney functions in the present experimental rats.

Bottled water like any drinking water used for human consumption should be safe and of standard quality to ensure adequate public health significance<strong><em>.</em></strong> But, the quality of bottled water used for human consumption is not subjected to any stringent quality control measure in Egypt. People buy bottled water for a variety of reasons, including convenience, fashion, and taste or because they think it is safer than tap water. The taste of the water has to do with the way it is treated and the quality of its source, including its natural mineral content. However, taste does not always indicate safeness. The samples were collected by random sampling technique. To asses the quality of bottled water in Al-Qalyubia, Egypt. The present study was carried out to determine the physicochemical, microbiological, sensory quality parameters and the concentration of heavy elements of six brands of bottled drinking water available in Al- Qalyubia and to compare with drinking water guidelines set by the WHO and the Egyptian Standard for bottled water(EOS). The results obtained showed that the physicochemical, microbiological and sensory parameters as well as the concentration of heavy elements in almost all the bottled drinking water were below the permissible limit set by WHO and Egyptian Standard (EOS). Hence, all the tested bottled water samples are safe for drinking purpose.

This study aimed to evaluate the effect of gamma irradiation at dose levels of 0, 1, 3 and 5kGy on the chemical composition, starch digestibility, pasting properties and cooking properties of two varieties of polished rice (Sakha104 and basmati). The results showed that the highest dose of gamma irradiation decreased the apparent amylose content, peak viscosity water absorption and minimum cooking time; while the fat absorption and solid loss were slightly increased. Irradiation showed increases in rabidly digestible starch (RDS) and slowly digestible starch (SDS), with consequent reductions in resistant starch (RS) for Sakha104variety. Furthermore, basmati rice displays a linear behavior over the range of radiation doses for RDS and SDS with a reduction in RS.

The current work was performed to investigate the safety of Halewet El-Moulid and cream cake handled in the local Egyptian market. Four kinds of Halewet El-Moulid samples were collected from 5 governorates. The potential chemical and microbiological hazards of collected samples were assessed. The obtained results reveal that all Halewet El-Moulid samples did not contain aflatoxins; however, their lead and copper content were varied between 0.02 – 0.71 and 0.62 – 3.8 ppm, respectively. Moreover, 50% of the extracted oil from samples containing oily seeds had peroxide values greater than the maximum acceptable limit. In spite of salmonella and fungal counts, all other measured microbiological cream cake sample hazards were unacceptable. These results indicate the necessity of imposing safety programs during processing, storage, and retail of food products.

This experiment was conducted at the Faculty of Agriculture, AL-Azhar University, Nasr City, Cairo, Egypt during the two winter seasons of 2018-2019 and 2019-2020 to study the effect of saline levels in the diluted agricultural drainage water of 1000, 2000, 3000, 4000 ppm and tap water as a control (300 ppm) and foliar seaweed extract concentrations of 400, 600 , 800 ppm and tap water as a control and their interaction on the growth, yield and fruits quality of tomato (<em>Lycopersicon esculentum </em>L.) Magy hybrid under plastic house conditions. The obtained results showed that plant height, leaf area, fruit fresh weight, size, length and diameter, leaf chlorophyll A, B and carotenoids contents, in addition to total yield as fruit number and weight significantly increased with using the saline level of 1000 ppm and the foliar seaweed extract concentration of 800 ppm. On contrast, fruit contents of T.S.S and dry matter significantly increased with increasing the saline water levels up to 4000 ppm and the seaweed extract concentrations at 800 ppm. Also, the data indicated that fruit content of ascorbic acid significantly increased from using the 2000 ppm level saline water and the concentration of 800 ppm seaweed extract. In this respect, it could be concluded that the application of the seaweed extract concentration at 800 ppm was the most effective to decrease the adverse effect of saline irrigation water on the growth and yield of tomato plants.

The present investigation was conducted on an experimental farm at the El-Kanater Horticultural Research Station in Qayubeia Governorate, Egypt during the 2018 and 2019 experimental seasons. The banana Williams cultivar were plant materials for this research, grown in clay loamy soil and the mates (plantation holes) were 3×4 meters apart under the flood irrigation system. Anyhow, Herosten the commercial name was the source of auxin used in this investigation. This compound contains (1.5 % NAA; 1.5 NAD and 1.5 % NAO), sprinkles were added sprinkles monthly five times during the period from first July to first November at a rate of 0.25, 0.375, 0.50 and 0.625 g per liter. Taking into consideration that sprays treatments were applied covering the whole bunch of each plant, whereas 0.5 liters was found to be sufficient in this concern to study the effect of different concentrations of Herosten sprays on productivity and fruit quality of Williams banana plants. Definitively, it can be shown from the results obtained that, spraying of Williams banana plants grown under similar environmental conditions and horticulture practices adopted in the current experiment with Herosten (auxin) at 0.375 g per liter and/or Herosten (auxin) at 0.50 g per liter is a beneficial method for enhancing production and fruit quality. In comparison, the lowest values of most of the parameters under investigation were typically associated with the control (water spray).

The habitat of microorganisms is different from one to another, some are naturally found in water environment, others are introduced due to different sources of contamination. The present study aimed to characterize the bacterial community of diverse water resources in Egypt in relation to the contamination source pursued them. So, water samples were collected from seven different water resources; groundwater, Nile River water, agricultural drainage water (El-Hussieniya drain), sewage contaminated drain (Bahr El-Baqr drain), industrial wastes contaminated drain (Al-Khadrawiya drain), fresh water Lake (Nasser Lake) and brackish water Lake (Qaroun Lake).
A total of 2218 bacterial isolates were collected, purified and identified by means of biochemical reactions and 16S rDNA sequence analysis to 21 bacterial genera. The sewage contaminated drain water (Bahr El-Baqr drain) has the highest diverse bacterial community, while the fresh water (Nasser) Lake has the lowest diverse community due to lake of contamination. <strong> </strong>In addition, <em>Bacillus, Pseudomonas and Staphyllococcus</em> were the most popular genera, where they have been detected in all types of water resources. The less popular genera were <em>Yersinia, Klebsiella, Aerumonas, Shigella, Salmonella, Cardiobacterium, Arthrobacter and Streptobacillus</em>, where they all have been detected once.

Field and laboratory studies were carried out during two successive summer seasons in order to study the susceptibility of the different tested Maize cultivars namely (Giza (2), Single cross (10), and Treble cross (321) to infestation by <strong><em>Rhopalosphum maidis </em></strong><strong>and</strong><strong><em>Rhopalosiphum padi</em></strong>. Field studies were carried out during the two consecutive growing seasons (2016 and 2017). There were significant differences in the susceptibility of Maize cultivars to infestation by these pests. Results showed that, G 2 and S.C (10) cultivars were the lowest infested ones by the two pests. On the other hand, T.C (321) variety was the highest infested cultivar. To give a spot light on the reason of the differences in the susceptibility of the tested Maize cultivars, chemical analysis of the dried leaves were carried out during growing season of 2017. Chemical analysis of infested leaves showed correlation between certain phytochemical components; potassium, total protein, carbohydrate, and phosphorous as well as Fiber , Vt B 6 and Vt B 1 content and population density of<strong><em> Rhopalosphum maidis</em></strong> <strong><em> </em></strong><strong>and</strong><strong><em>Rhopalosiphum padi</em></strong>.

<em>Culex pipiens </em>(L.) (Diptera: Culicidae) is the most important medical insect in many parts of the world. Biological and natural chemicals have many advantages over the traditional ones in case of mosquito control. The efficacy of two insecticides belonging to different groups chlorpyrifos-ethyle (oranophosphate) and <em>Bacillus</em> <em>thuranginsis</em> var <em>israelinsis</em>) (bio-insecticides)were evaluated against the field and laboratory individuals of late 3<sup>rd</sup> instar larvae of <em>Culex pipiens </em>at different concentrations and three periods of exposure under laboratory conditions. Results obtained showed that the laboratory strain showed higher susceptibility to the tested insecticides than the mosquito populations collected from Abo-Rewash City, Giza Governorate and the mortality percentage was increased gradually with increasing the insecticide concentrations and the mortality percentage showed significant differences between concentrations and control. Also, The activity of acetyl cholinesterase (AChE), the glutathione <em>S</em>- transferase (GST), Total proteins and the activities of both Aspartate aminotransferase AST(GOT) and Alanine aminotransferase ALT(GPT) were determined were determined after 72 hrs of insecticidal exposure.

The irrigation network in Egypt consists of a group of canals that deliver water to cultivated areas, which necessitates maintaining these canals and not violating the sanctuaries and bridges of these channels, whether by building or filling with solid waste and rationalizing the use of water by farmers at the beginning of the canal is supplied the water to all crops located on canals, at the appropriate time and in quantities.
The problem of water not having sufficient access to some agricultural resources at the end of the Al-Sharqawiyah Canal is one of the most important problems faced by the Central Administration of Water Resources and Irrigation in Qalyubia. Accordingly, the research assessed the status of the waterway and estimated some economic and social indicators of some agricultural crops during the 2018/2019 agricultural season in the study area.
The results of the research showed that the Al-Sharqawiyah Canal suffers from a decrease in hydraulic efficiency, which led to the intolerance of the behaviors required to irrigate all the area it serves, and showed the decrease in the average agricultural productivity of winter crops at the end of the canal from the beginning by ratios ranging from (7.3 : 9.6), as shown to be the decrease in the average feddan productivity of summer crops at the end of the canal from the beginning in proportions ranging from (4.8: 8.3)% with the increase of average cost of feddan production at the end of the canal from the beginning in proportions ranging from (0.4: 4.3), (1.7: 2.3) for winter and summer crops, respectively,, The results also indicated a decrease in the average net yield per feddan for winter and summer crops at the end of the canal at the beginning they ranged from (16.0: 42.8%), (17.3: 28.6)% respectively, and (T- test) showed a significant differences at 1% during the 2018/2019 season.
The study estimated the amount of income losses during the same agricultural season of crops in Qalyub and Shabin Al-Qanater at 147 million L.E/year.
Accordingly, the research recommended the need to rehabilitate the canal and return it to its design status as much as possible, with lining and rehabilitating the sub-canals that feed from Al-Sharqawiyah Canal within a period of not more than 3 years.

Egypt occupies the first place among the countries of Africa and the first place in the production of fish from fish farming among the countries of the Mediterranean and the Middle East, as well as the sixth place in the world in fish farming. Marine fish farming in Egypt suffers from many political and legal obstacles, as well as old laws and legislations that require strong and radical amendments, with disputes over the use of natural resources (land and water). The study aims to: (1) A description and analysis of the most important productive and economic variables in fish farms according to three farmer production capacities. (2) Identify and describe the most important production, technical, technical, economic, marketing, and structural problems related to the infrastructure of the fish farms under study. (3) Estimating and measuring the individual or simple impact of the most important production, technical, technical, economic, marketing and structural problems of the infrastructure of the fish farms under study on the total production of marine fish in the study area. In achieving its previous objectives, the study relied on preliminary field data collected from 95 marine fish farms on the northern coast during the production cycle for the period 2019/2020.

Maize is one of the main and important cereal crops in Egypt, due to the multiplicity of areas of its use, whether it is human food (human) and animal food (animal and poultry), and the newly reclaimed and cultivated lands form an important part of the state's plan for horizontal expansion and large areas of these lands can be cultivated. The study focused on identifying the current production status of the maize crop in the Sharkia governorate compared to the republic during the period (2008-2018) as it was estimated that the production of maize increased and the quantities imported from abroad which were used as fodder. The area cultivated from the maize crop across the Republic is about 2,166.14 thousand feddans during the period from (2008-2018), while the annual average of the cultivated area in Sharkia governorate is about 248.95 thousand feddans, representing the average cultivated area in the Sharkia governorate to its counterparts at the level of the Republic during the previous period about 11.61 %, And the average feddan productivity reached 3.25 tons / acre, 3.34 tons / acre at the level of the Republic and the Eastern Governorate respectively. As for the total production of the maize crop, the average production amounted to 6908.53 thousand tons, 852.07 thousand tons at the level of the Republic, and the Eastern Governorate, respectively, and the average total production of the Eastern Province represents about 12.38% for the Republic during the study period. By studying some economic indicators of the maize crop, it was found that the agricultural price of the maize crop during the study period increased at an annual increasing rate of about 23.66 pounds / ardeb, at an increase rate of about 7.6% of the average farm price of the crop, which amounted to about 309.45 during the study period, While the total costs increase at an annual increasing rate by about 388.78 pounds / acre, at an increase rate of about 10.97% of the average total costs, which were estimated at 3544.45 pounds / feddan during the study period, while the net yield of maize crop was estimated and took a decreasing rate of about 33.62 pounds / acre. With a change rate of about -1.39%. While the economic efficiency of the seed elements, municipal fertilizer, mechanical work, nitrogen fertilizer, potassium fertilizer, the amount of water according to the drip irrigation system for maize crops in Al Salhia center was estimated at 2.03, 1.11, 1.62, 4.07, 8.14, 10.96, 31.27, 31.27, 6.65. Accordingly, the total cost per acre of maize crop with flood irrigation system reached about 7467 pounds, and the drip irrigation system reached 1394.6 pounds. While the net yield of the acre of the maize crop in the flood irrigation system amounted to about 3875.5 pounds, and it was also found that the cost of producing the unit (ardab) of the maize crop amounted to about 262.28 pounds in the flood irrigation system, 201.63 pounds for the drip irrigation system, and the total return per unit (Ardab) Of the maize crop in the flood irrigation system, about 311.26 pounds, and about 339.36 pounds in the drip irrigation system. The unit return from water was about 3.8 pounds / m3 for the maize crop in the flood irrigation system, and it reached 4.5 for the maize crop in the drip irrigation system. The water for maize crop by flood irrigation system was about 0.6 pounds / m3, while it was about 1.8 pounds / m3 for maize crop by drip irrigation system. As for the cost of the water unit for the total costs, it reached 3.2 pounds / m3, and it reached about 2.6 pounds / m3 for the maize crop. With flood irrigation system, drip irrigation respectively

<strong> </strong>The e wheat crop is considered one of the most important strategic grain crops in the Egyptian and international agricultural sector, as it is the main food for humans as it is a basic source of energy because it contains a large percentage of carbohydrates. The study focused on identifying the current production status of the wheat crop in the Sharkia Governorate compared to the Republic during the period (2008 - 2018), as it was estimated that the average area cultivated with wheat crops at the level of the Republic was about 3.2 million feddans during the period (2008-2018), while the annual average of the cultivated area in Sharkia governorate reached 401.78 thousand feddans, 12.7% of the republic during the aforementioned period, while the total production reached At the level of Sharkia Governorate, about 1.14 million tons, or 13.23% of the republic, amounting to 8.66 million tons during the study period. By studying some economic indicators of the wheat crop, it was found that the agricultural price increased during the period (2008-2018) by about 25.27 pounds /erdeb, at an increase rate of about 6.3% of the average agricultural price for the crop, which amounted to about 397.54 pounds. The total costs increased at an annual increasing rate of about 318.83. EGP / acre, at an increase rate of about 6.7% of the average total cost of the crop, which amounted to about 4758.27 pounds/acre during the study period. By estimating the economic efficiency of the elements of wheat crop production according to the flood irrigation system in the Sharkia Governorate, it is clear that it was estimated at 4.79, 0.54, 3.95, 0.46, 49.30, -1.51 for the elements of seeds, municipal fertilizer, human labor, mechanical work, nitrogen fertilizer, the amount of water for each of them on The arrangement, while the economic efficiency of the elements of municipal fertilizer, human labor, mechanical work, nitrogen fertilizer, phosphate fertilizer, and the amount of water in the sprinkler irrigation system for the wheat crop in Al-Salhia center were estimated at 0.62, 1.47, 1.65, 23.05, 46.52 and 2.02 respectively. This shows the high economic efficiency of the majority of production elements according to the traditional irrigation and sprinkler irrigation systems for wheat farmers in the sample of the study, which requires the possibility of increasing the amount used from other elements in accordance with the technical standards to reach maximum economic efficiency. Wheat, according to the flood irrigation system, amounted to about 15844.96 pounds, while the total feddan yield from the wheat crop for the sprinkler irrigation system was about 17,482.74, while the net yield per feddan of the wheat crop in the flood irrigation system amounted to about 5291.4 pounds, and about 8900.1 pounds with the sprinkler irrigation system. Whereas, the net return of the water unit for the wheat crop in the flood irrigation system amounted to about 2.09 pounds / m3, while it reached about 5.3 pounds / m3 for the wheat crop with the sprinkler irrigation system, the cost of the water unit for the total costs was estimated at 4.17 pounds / m3, and about 5.17 pounds / m3 under the two irrigation systems By immersion, sprinkler irrigation all in order.

The date fruits are considered one of the most important food for the inhabitants of desert areas, especially the New Valley Governorate. It occupies the leading position distinctively among other agricultural products. It is also considered an agricultural heritage and represents the present and future of the province.
As the area of palm trees reached about 25.94 thousand feddans in the New Valley Governorate, representing about 22.2% of the total area of the Arab Republic of Egypt, which is about 117.07 thousand feddans. The number of fruitful females of the date palms in the New Valley reached about 1757.87 thousand palm trees, representing about 12.22% of the total number of fruitful females in the Arab Republic of Egypt, which amounted to about 14.38 million date palms.
As for the average productivity of a palm tree in the New Valley, it amounted to about 78.17 kg of palm trees, representing about 68.36% of the total average productivity of a palm tree in the Arab Republic of Egypt, which is about 114.36 kg / palm. As for the total production of palm trees in the New Valley, it amounted to about 137.42 thousand tons, which represents about 8.36% of the total palm production at the level of the Arab Republic of Egypt, and about 1.64 million tons, during the year 2019, and the problem of the study was that the cultivation of date palms in the New Valley governorate.
To reduce the phenomenon of desertification and its suitability to the environmental conditions and factors to preserve. Despite the availability of space and the number of fruitful females, the average productivity of the palm does not reflect the expectations of this production. The average productivity of a palm tree during the period (2015/2019) was about 80.12 kg / palm tree during the period (2015/2019), while the average productivity of a palm during the same period at the level of the Republic was about 113.65 kg / palm. This necessitates identifying the most important causes of this decline, as the problem of the study is also not to make use of the huge quantities of agricultural residues accumulated from date palms in farms, which results in significant pollution of the environment.
While this waste contains a large amount of mineral elements, it is lost by burning. Although there is a compost gap that can be closed by recycling this waste and converting it into organic fertilizer that can be used to improve the properties of the soil. The study aims to estimate the efficiency of using the available economic resources. For the production of date palms in the New Valley Governorate, in order to rationalize the use of these resources, the development of production indicators for the production of dates in the New Valley Governorate and the Republic and the estimation of technical efficiency in accordance with the concept of fixed yield and variable yield of capacity for sample farms.
Estimating the distributional efficiency and economic efficiency of date farms in the New Valley Governorate and estimating the optimal use of economic resources for date farms in the New Valley Governorate that the average cultivated area is from 16.5 acres to 16.3 acres / farm, and the average amount of water needs to be reduced from 1100 to about 1009 thousand cubic meters / On a farm, as well as reducing the amount of organic fertilizer from 1.1 to 1 meters, reducing the amount of municipal fertilizer used from 1.3 to 0.8 cubic meters / farm, and also reducing the layer of nitrogen fertilizer from 140 to 120 tons / farm, and also reducing the amount of phosphate fertilizer from 12 to 8 Tons / farm, and reducing the number of normal employment from 102 to 98 workers / farms, provided that the farm achieves full economic efficiency, as the index value reached 63%.
