This investigation was conducted at Gemmiza Agric. Res. Station during the two successive winter seasons of 2014/2015 and 2015/2016 to study the differences among nine flax genotypes namelyline 541/D/10, Sakha 2, line 402/11/6, Sakha 3, Giza 9, Ilona, line 22, line 2467/3 and line 435/11.The experiments trails were carried out in Randomized Complete Block Design (RCBD) with four replications. Results revealed that the flax line 541/D/10 ranked the first and surpass the remain flax genotypes in biological yield/fad., straw yield/fad., fiber yield/fad., fiber %, fiber length, seed yield/fad., seed index, oil %, oil yield/fad., Iodine value, crude protein %, in seeds and total carbohydrates % in seeds. But this line occupied the fourth position concerning fiber fineness trait. The flax variety Giza 9 ranked second in all fiber characters, while line 2467/3 was the fewest in biological yield/fad., straw yield/fad., fiber yield/fad. and fiber percentage.
The line 22 ranked second regarding seed yield/fad., oil % and oil yield/fad. The flax variety Ilona achieved highest estimates for cellulose %, moisture % in seeds and crude fiber % in seeds. On the other hand, Ilona gave the lowest estimates in seed yield characters.
Correlation coefficient(r) values were highly significant and positive between fiber yield/fad. and each of biological yield/fad., straw yield/fad., fiber %, fiber length, fiber fineness, lignin % and waxes %. While it was significant and positive with each of cellulose %, and pectin %. The( r ) values recorded highly significant and positive between seed yield/fad. and each of oil yield/fad., seed index, oil %, total crude protein % (in seeds) and total carbohydrates % (in seeds). While correlation coefficient(r) values were significant and positive with either Iodine value and crude protein% in seeds.

A field experiment was conducted on saline clay soil located at the experimental Farm of Sahl- El-Houssinia Agriculture Research Station, El-Sharkia governorate, Egypt, during two winter seasons of 2014/2015 and 2015/2016. These experiments aimed to study the effect of irrigation intervals and compost rates alone or combined on soil fertility and fahl clover productivity and quality under newly reclaimed saline soil conditions. The experimental treatments were arranged in a split plot design with four replicates. The main plots represented the three irrigation intervals (12, 16 and 20 days), whereas the sub-main plots represented compost rates (0, 5, 10, and 15 ton/fad). The results revealed that the effect of irrigation intervals and compost rates were positive on all growth traits of fahl clover and saline soil properties during the two seasons.
Irrigation intervals had a significant effect on growth traits and yield of clover crop and maximum values were obtained with the 12 days irrigation interval. On the contrary, minimum values for the corresponding respective characters were recorded with the 20 days irrigation interval.
The increase of compost rate (5, 10 and 15 ton /fad) gave increases of all growth traits and yield compared with the control. Also, the interaction between irrigation intervals and compost rates was significant on all studied traits and yield. The 12 days interval combined with all compost rates gave the highest values of studied growth traits as well as forage yields. Results showed that the application of compost increased the chemical composition contents of clover plants and soil properties after harvest as well.

2016
eng
Weeds are one of the biggest obstacles to upgrade wheat production. Using the proper seeding rate and applying effective weeding program are among the factors suppress weeds, improve wheat grain yield and quality. This study aimed at evaluating the effects of weed control treatments i.e. Bromoxynil (Brominal) (24% EC), Clodinafop-Propargyl (Topik) (15% WP), Brominal + Topik, hand weeding as compared to unweeding check; four seeding rates viz. 60, 80, 100 and 120 kg /feddan (fed)* and their interaction on productivity of durum wheat and associated weeds. The results revealed that increasing seeding rate from 60 to 120 kg/fed caused great reduction in dry weights of weeds. Brominal + Topik gave the highest reduction in dry weight of grassy, broadleaf and total weeds. Applying Brominal + Topikwith 100 or 120 kg/fed seeding rate was the best combination for controlling weeds. Increasing seeding rates from 60 to 100 kg/fed significantly increased number of spikes/m2 and grains/spike in one season only. Weight of 1000 grains was decreased with increasing seeding rate from 60 to 120 kg/fed. Grain yield was increased when seeding rate increased from 60 to 100 kg/fed. Brominal + Topik treatment was superior in improving most wheat yield components, grain and straw yields. In practice grain yield increased by 43 and 38% as compared to the unweeded plots in first and second seasons, respectively. Using 80 or 100 kg/fed seeding rate with Brominal + Topik as post emergence herbicides would be recommended for achieving high grain yield (21 ardeb/fed)** under similar conditions of desert reclaimed soil highly infested by weeds.

Endogenous changes exhibited by Le-Conte pear trees subjected to various irrigation regimes and their impact on vegetative growth
text
article
2016
eng
This study was carried out during three successive seasons 2013, 2014 and 2015 on seventeen years old Le-Conte pear trees. The first season was a preliminary season to eliminate the residual effects of the previously used irrigation treatments. Pear growing season was into four phenological stages (stage I beginning of flowering to final fruit set, stage II from initial fruit set to final fruit set, stage III final fruit set to harvesting and stage IV harvesting to leaf shed). Control trees received 100 % of crop water requirement during all stages while the remaining trees received either of three water regimes (60, 80 or 120% of crop water requirement) applied at one of the specified phenological stages and then irrigated with 100% of the requirements for the remaining. The effects of applied regimes on some vegetative growth parameters, enzymatic activities activity, phytohormons, total proteins, carbohydrates, phenols and proline were assessed. Results showed clear enhancements in vegetative growth induced by applying 120% of the actual requirement during any of the considered stages, proline declined by increasing the applied water quantities, whereas, an opposite trend was evident with protein content. Lowest irrigation regime (60%) added at any of the considered stages significantly induced highest leaf carbohydrates, phenol content, polyphenol oxidase (PPO) & Peroxidase (Pro) activates, ABA and SA content when compared with higher irrigation regimes at same stages. Growth promoting hormones as GA3, IAA and CKs contents attained an opposite trend. Finally it was concluded that various responses of vegetative growth to applied regimes was a reflection of the endogenous changes exhibited by the trees.

This study was carried out during three successive seasons 2013, 2014 and 2015 on seventeen years old Le-Conte pear trees. The first season was considered to be on preliminary season to eliminate the residual effects of the previously used irrigation treatments. Pear growing season was split to four phenological stages (stage I beginning of flowering to final fruit set, stage II from initial fruit set to final fruit set, stage III final fruit set to harvesting and stage IV harvesting to leaf shed). However, control trees received 100 % of crop water requirement during all stages while the remaining trees received three water regimes (60, 80 and 120% of crop water requirement) applied at each of the phonological stages and then irrigated with the stayed stages were receiving optimal level of irrigation requirement (100 %) for the remaining stages. The fruit set%, fruit abscission%, yield (Kg), fruit characteristic (fruit weight (gm.), fruit firmness, juice TSS % titratable acidity %), chemical analysis (Leaf content of macro nutrients (nitrogen, phosphorous, potassium content (%),magnesium, iron , zinc, manganese and coppercontents (mg/l) and leaf content of photosynthetic pigments (chlorophyll (a,b) and carotenoids) parameters were assessed.
Results showed that enhancements of fruit set percentage were induced by applying 60% of the actual requirement during stage II, fruit abscission declined by increasing the applied water quantities during stage IV and producing significantly the highest yield per tree, fruit weight increase by increasing the applied water quantities during stage III, firmness and TSS increases with decreasing the actual requirement during any studied stages, the highest leaf nitrogen content was due to applying the highest regime during stage III, increasing potassium, phosphorus, magnesium, iron , copper and chlorophyll contents were attributed to the lowest regime when applied during stage II, leaf zinc and manganese content increased by applying the highest regime during stage II.

2016
eng
A potfactorial experiment was carried out to investigate the effect of plants inoculation by four levels from arbuscular mycorrhizal (AM) fungi spores (zero, 150, 300 and 450±10 spores plant -1) with six NPK fertilizer ratios (0:0:0, 0:10:5, 5:10:5, 10:5:5, 5:5:5 and 5:0:5) on the growth traits of Swieteina mahogany seedlings under sandy soil conditions. The inoculums of AM fungi were used as mixed spores for one genus with three species Glomus mosseae, G. etunicatum and G. clarum. The results were shown that the high values in all plant growth parameters and NPK plant uptake in biomass were recorded at plant treated with NPK at ratio 10:05:05 in the presence of 450 AM spores plant1. Also the high level of plant chlorophyll a; chlorophyll b and carotenoids were observed at plants treated with 300 AM spores plant-1 at NPK ratio10:05:05. The AM spore’s numbers were increased at NPK fertilization ratio 0:10:05 at all levels of inoculation. While the AM root colonization% was increased by increasing in both addition of nitrogen and phosphorus fertilization. The combination between AM fungi and NPK fertilization had better growth effect on increased NPK plant uptake when comparison between other treatments. The positive effects of plant inoculation only by AM fungi were helped S. mahagonito absorb more nutrients from soil more than plants free from AM treatment.

This work was carried out during two seasons of 2012/2013 and 2013/2014 in the agricultural research center in El Khassasen .The aim of the this study was to investigate the effect of arbuscular mycorrhizal (AM) fungi inoculation with sewage sludge on the growth of Swieteina mahagoni, seedlings. The AM fungi were used as a mixed culture from species of Glomus mosseae, G. etunicatum and G. clarum..The factorial pot experiment was designed in six amount from sewage sludge (control, 250, 500, 750, 100 and 1250 g plant1) with four levels of AM fungi (zero, 150, 300 and 450±10 spores plant-1). The results shown that, the maximum values in all plant growth parameter were recorded in the plant treated with 500g sewage sludge with AM fungi inoculation rate300, 450 spores/ plant and NPK % in plants leaves was obtained from 500g with 300 and450spores/plant of AM fungi inoculation. The maximum amount of plant chlorophyll a, chlorophyll b and carotenoids were found at plants treated with AM fungi by rate 300 spores/ plant with 500g sewage sludge. The addition of AM fungi to sewage sludge had better growth effect and NPK uptake when comparison between treatments. This is due to the mutual positive action of S. mahagoni and AM fungi species that helped to absorb more NPK fertilization from soil.

Efficacy of some biotic and abiotic treatments in controlling Alternariasolani the causal of tomato early blight disease in vitro and in vivo
text
article
2016
eng
Early blight of tomato caused by Alternariasolaniis one of the most common foliar diseases of tomato. Fivetested Trichoderma isolates were most effective in reducing growth of A. solani(As-3) than the tested Bacillus isolates. The highest reduction% was recorded with Trichodermaaureoviride-I(T-1) followed by Trichodermaaureoviride-II (T-2), Bacillussubtilis-I (B-24) and Bacillusamyloliquefaciens-II(B-19). Spraying plants with any of the tested antagonists before inoculation with A. solani under greenhouse conditions decreased the early blight disease severity (DS) by 15.1 to 45.3% compared with the infected control treatment with the pathogen only which recorded 93.4% of DS%. Bacillus amyloliquefaciens-II (B-19),T. virens (T-11)and T. harzianum-II (T-13) were the most effective for controlling early blight disease at 21-day post inoculation. All plant oils reduced the growth of A. solani isolate (As-3) with superiority of the high concentrations. The highest decreased % in growth of A. solani occurred with the 6.0% concentration. Among the five plant oils, cinnamon was the most effective followed by cloves then marjoram, while garlic was the least effective. Moreover, all oils at 3% concentration were moderately effective in controlling the disease. Clove and marjoram oil were the most effective in decreasing the infection at 21-day post inoculation with the pathogen while, garlic oil was the least effective. All tested chemical inducers reduced the growth of A. solani(As-3) on PDA plates. The high concentration 400 mM of sodium bicarbonate and potassium hydrogen carbonate was the most effective. Salicylic acid at 3 and 5mM was more effective in reducing the growth of isolate As-3 compared with the same concentrations of ascorbic acid. Spraying plants with the tested chemical inducers against early blight disease caused by A. solani(As-3) was moderately effective in controlling the infection. All tested chemical inducers controlled the early blight infection where the recorded DS% was ranged between 30.1 to 45.4% at 21day post inoculation with A. solani(As-3). Spraying tomato plants with salicylic acid was the most effective treatment in controlling A. solani (As-3) infection compared with the other chemical inducers.

To reduce the numbers of thrips and comparison using some chemical pesticides and other non-chemical materials, field studies were carried out to assaying the effectiveness of those materials against nymphs and adults of Thrips tabaci on onion in the Qalyubia governorate during 2014/2015 and 2015/2016 seasons. The results showed that chemical insecticide (Radiant 12%) gave high reductions being 95.1% and 89.5% during the first season while, these were 87.1 and 81.6% during the second season for nymphs and adults of onion thrips, respectively. On the other hand, chemical insecticides Lannate 90, Mospilan and some non-chemical materials such as Garlic and Parsley oil and Chinafill 100 showed intermediate effects against nymphs and adults. The insect growth inhibitor (Admiral) showed a weak impact on nymphs and adults of onion thrips as 14.9& 14.3% for 1st season and 45& 34.9% in the second one for adults and nymphs, respectively. In all cases, the difference between the percentages of reduction for Radiant 12% and Lannate 90 was non-significant during the first season of study while, there was a clear significant difference between both Radiant 12% and the other tested compounds during the second season. Also, the obtained results show that, there were no significant differences between reductions by the remaining tested compounds.

Squash plants were sprayed with Vertimec (abamectin) 1.8% EC and Ritreap (cyflufenamid) 5% EW at the rate of 40 cm3 / 100 L water and 20 cm3 / 100 L water, respectively during the summer season of 2016. Samples leaves, fruits and soil were collected at 2 hrs to 12 days after application and QuEChERS method was used for extraction and clean-up and analyzed using HPLC and gas chromatography for abamectin and cyflufenamid, respectively. Results revealed that, the initial amounts of each pesticide in leaves were much higher than those in squash fruits. Loss percentages in residues were higher in squash fruits than leaves. The residues amounts of the two tested pesticides were more greatly detected in peel than that the pulp. Data also show that washing and peeling of squash fruits resulted in removing reasonable amounts of residues especially with the first three samples. The rate of dissipation in abamectin was more than in cyflufenamid and the consumable safety time was 6 days after application of these pesticides on Squash fruits.

eng
Economic injury and economic threshold levels were estimated for the two spotted spider mite, Tetranychus cucurbitacearum (Sayed) (Acari, Tetranychidae) on soybean plants. An attempt was made to determine, mathematically, the point at which a significant reduction occurs in the yield of soybean at different levels of infestation by the two spotted spider mite, T. cucurbitacearum. For this purpose, counts were taken during each of the main three annual peaks of this mite infestation over two seasons of (2015and 2016). The obtained results indicated that the mean values of economic injury level were 28.97 and 22.01 individuals / leaflet , while mean values of economic threshold levels were 32.05 and 21.23 individuals / leaflet during 2015 and 2016 seasons, respectively, while the general mean of economic threshold and economic injury levels were 21.23 individuals per leaflet and 18.21 individuals per leaflet, respectively.

The present work was conducted during the two summer successive seasons, 2014 and 2015 to study the population fluctuations of the red spider mite Tetranychus urticae Koch, cow pea aphid Aphis craccivora Koch, American serpentine leaf miner Liriomyza trifolii (Burgess), cotton whitefly Bemesia tabaci (Genn.), potato leafhopper Empoasca decipiens (Paoli), cotton thrips Thrips tabaci L. and cotton aphid Aphis gossypii Glover infesting kidney bean plants at Abo Hammad district, Sharkia governorate, Egypt. The aforementioned pests were collected by two different methods from kidney bean plantation using plant samples and sweeping net. The obtained results showed that the plant samples proved to be the best method to investigate mite, aphids, leaf miner (larvae), whitefly and thrips pests, while sweeping net proved to be the best technique to investigate the potato leafhoppers. The seasonal abundance ofT. urticae and L. trifoliishowed three peaks of population density, while the results of A. craccivora,B. tabaci, E. decipiens on kidney bean plants showed two peaks of population density during two seasons. On the other hand T. tabaci recorded one peak of population density. Regarding to the effect of mean temperature and atmospheric relative humidity as well as their total combined effect on the numbers of certain investigated pests, it is obvious that the effect was clear.

eng
The presented study was carried out during spring season of 2016 at the laboratory of Department of Plant Protection, Faculty of Agriculture AL-Azhar University. It was planned to evaluate the certain biological and economic parameters of (HoxKKxG2xV2) hybrid of silkworm, Bombyx mori (L.) fed on mulberry leaves Morus alba (Rose variety), supplemented with four types of protein sources (pollen grains, royal jelly,an amino acid and bee honey) during fourth and fifth instars of B.mori larvae, and to study the impact of these supplements on the larval duration, and cocoon, shell and pupal weight and shell ratio. Many studies were accomplished on the effects of mulberry leaves enrichment with protein supplements on certain biological and economic parameters. One of the alternative ways to improve the larval feeding is the enrichment of mulberry leaves with supplementary pollen grains, royal jelly, amino acid and bee honey. Obtained results showed that feeding of larvae on leaves supplemented by pollen grains, royal jelly, amino acid and bee honey increased fresh cocoon weight, cocoon shell weight; shell/ cocoon ratio. Also such feeding led to shorter larval duration and decreased larval mortality percentages.

2016
eng
A field experiment was conducted along two successive seasons of summer (2014 and 2015) at El-Nubaria Agricultural Experimental Station of the Agricultural Research Center (A.R.C), west of Alexandria. The experiment was laid out to evaluate the effect of two tillage methods: conventional tillage (CT) and no-tillage (NT) and five phosphorous fertilizer treatments in sub plot as follows: P0: without addition, PG1: 240 kg ha-1, PG2: 480 kg ha-1 as granular, PP1: 240 kg ha-1 and PP2: 480 kg ha-1 as powder on soil and maize plant ( Zea mays L.) .
Tillage methods affected increased of saturated hydraulic conductivity (Ksat) and total porosity (TP), decreased the bulk density of soil under conventional tillage (CT). Effects occurred in the three depths of the soil layers (0-10), (10-20) and (20-30) cm. The reduction percentages of bulk density values were 8.2, 2.9 and 4.9 % for the three layers, respectively. Yields were increased under CT as compared to no NT. the harvest index was not significantly affected. There were differences in yield responding to phosphorus treatments. Under CT, granular P gave higher yields than powder P and the reverse occurred under NT. Phosphorous content and uptake of grain and straw were significantly affected by phosphorus treatments under both tillage methods. Conventional tillage increased P content and uptake in grain by 14 and 31 % respectively, corresponding increase in P content and uptake in straw were 27 and 45 % respectively. Under CT, treatment PG2 recorded the highest values of P content and uptake in grain (0.793 % and 59.59kgha-1). Corresponding increase in P content and uptake in straw were 0.330 % and 36.79kgha-1. Under NT, the treatment PP2 was recorded the highest values (0.777 % and 52.56 kg ha-1) for phosphorous content and uptake for grain only.

A field experiment was conducted along two the successive seasons of winter (2014/2015) and (2015/2016) at El-Nubaria Agricultural Experimental Station of the Agricultural Research Center (ARC), west of Alexandria, Egypt. Aim was to evaluate the effect of arbuscular mycorrhiza fungi (AMF) and rock phosphate (RP) application as well as the effect of irrigation intervals on soil properties and growth of wheat (Triticum aestivum L.) grown on sandy clay loam calcareous soil. The experiment was factorial (3 factors) with 12 treatments and three replicates. Three irrigation intervals 15, 21and 35 days, two RP treatments non and 16 kg P ha-1 and two AMF (non and AMF) treatments. AMF under moderate 21 day irrigation interval combined with RP was mostly effective in increasing total porosityand saturated hydraulic conductivity as well as decreasing bulk density. AMF + RP and irrigation every 21 days gave highest values of most growth and yield characters along with NPK content.
