Some Agronomical Practices for Improving Growth ,Yield and Quality of Pea Growing at Late Seasons. بعض الممارسات الزراعية لتحسين النمو والمحصول والجودة للبسلة المنزرعة في العروات المتأخرة
This work was carried out at the Experimental Farm of El-Baramoon Research Station, Horticulture Research Institute, Agricultural Research Center, during the late winter season of 2018 and 2019 to study the effect of two sowing dates (20th January and 20th February), foliar applications, i.e., brassinolide (5 and10 mg/l), mixture of growth regulator (0.5 and 1cm/l), dry yeast extract (5 and 10gm/l) potassium nitrate (1 and 2 gm/l) and potassium silicate (2.5 and 5gm/l) in addition to vernalization practice and their interactions on growth, yield and its components characteristics of pea cv. Master- B.The obtained results revealed that, the first sowing date induced a higher growth values , yield and its components and chemical composition of seeds compared with the second sowing date. Spraying brassinolide at 10 mg/l gave the highest growth, yield and chemical components of pea plants, followed by potassium nitrate at 2gm/l, growth regulators mixture at 1cm/l and yeast extract at 10gm/l. Sowing pea seeds in 20th January and spraying with brassinolide at 10 mg/l introduced the best interaction with respect to growth, yield components and chemical composition of seeds. From the obtained results it could be recommended that sowing pea in 20th January and spraying with brassinolide (10 mg/l) and/or potassium nitrate at 2gm/l, and/or growth regulators mixture at 1cm/l and/or yeast extract at 10 gm/l improved growth, yield and chemical composition of pea growing at late season conditions .

Effect of N-Levels and Foliar Application Treatments on Productivity of Sunflower تأثير مستويات السماد النيتروجينى ومعاملات الرش الورقى على إنتاجية عباد الشمس
Field experimentations were carried out to examine the impact of N-levels and foliar application treatments on yield characters of sunflower cultivar Sakha-53 during 2016 and 2017 seasons at El-Muhandis Village in Sherbin District, Dakahlia Governorate, Egypt. Experimentations were conducted using a strip plot design with three replicates. Vertical plots were devoted to nitrogen fertilizer rates (20, 25 and 30 kg N/fed). While, six spraying transactions i.e. without, water spraying, amino acids (AA), yeast extract (YE), commercial NPK + micro elements (Fe, Mn and Cu) as Estima-Green powder, and the mix of AA, YE and commercial NPK + micro-elements were distributed on the horizontal plots. Fertilizing with 30 kg N/fed yielded the maximum rates of yield and its attributes during 1st and 2nd years. Fertilizing with 25 kg N/fed came after the maximum rate of N fertilizer. The spraying two times with the mix of AA, YE and commercial NPK + micro-elements gave the maximum rates of crop and its components in both years, then spraying sunflower plants twice with commercial NPK + Micro (1.5 g/L) in every spray. It can be accomplished that sunflower cultivar Sakha-53 with 25 kg N fed-1 as well as spraying twice with the mix of AA, yeast extract and commercial NPK + Micro so as to preserve high productivity at the same time decrease production expenses and ecological contamination under the ecological circumstances of Dakahlia- Governorate, Egypt.

Graphical Presentation of some Peanut Genotypes by Comparing Two Patterns of Biplot Analysis العرض البياني لبعض التراکيب الوراثية للفول السوداني بمقارنة نموذجين من تحليل المحاور الثنائية
The present work was carried out at the Agriculture Research Station of Shandwell during the two successive seasons of 2018 and 2019 to assess the yield potential of 20 peanut genotypes. Genotype by trait biplot (GT) and genotype by yield*trait (GYT) analyses were automated to obtain information on genotypes for selection based on multiple traits (nine traits), and appreciate the relationships between these attributes. Applying biplot analyses to the multiple trait data revealed that genotype by yield*trait (GYT) graphically facilitated visual, more effective and clear in providing information about the superior genotypes and the relationships between the yield and its components genotype compared to trait biplot (GT). Also, ranking genotypes was tested by a superiority index that collective yield and other target traits with the GYT biplot. In the GYT biplot, yield-trait combinations clearly appeared that the best genotypes defined for all traits, whereas in the genotype × trait (GT) biplot, the best genotypes were not known for all traits. The promising genotypes being No. 7, 16 and 17 are clearly observed using the GYT biplot technique.

An Efficient Protocol for Direct Organogenesis of Pepper (Capsicum annuum) التکوين العضوى المباشر فى نبات الفلفل
A simple and efficient plantlet regeneration protocol was established for Pepper (Capsicum annum L.) achieved through direct organogenesis from Leaves and cotyledons explants. Leaves were taken from 21 day- old in vitro plantlets and and cultured on Murashige and Skoog (1962) MS medium supplemented with different growth regulators. Thidiazuran (TDZ )or Benzyl adenine (BA) with Indole 3-acetic acid (IAA) containing medium was tested. Prolific direct adventitious shoot regeneration occurred on most of the tested growth regulators. The best response in terms of frequency of shoots number per explant (10.5) was obtained from cotyledon cultured on 1.0 mg/L TDZ in combination with 0.5 mg/L IAA. To elongate the shoots it were cultured on MS medium supplemented with various concentrations of gibberellic acid (GA3 ) in combination with 0.25 mg/L Kinetin (KIN). The highest shoot length (2.2 cm) was achieved on MS medium supplemented with 0.5 mg/L GA3 and 0.25 mg/L KIN. Regenerated shoots were excised to root. The highest number of root/shoot was obtained with quarter MS salt medium supplemented with 1.0 mg/L indole-3- butyric acid (IBA) with high length of root (4.60). plantlets were finally transferred to mixture of peatmoss, vermiculite and sand at equal volume 1:1:1.The plantlets showed 80 % survival after 30 days during acclimatization and transplanting.

Effect of Salicylic Acid and Foliar Spraying with some Microelements on Seed Yield and Quality of some Pea (Pisum sativum L.) Cultivars تأثير حامض السلسليک والرش ببعض العناصر الصغرى على المحصول الطازج والبذري والجودة لبعض أصناف البسلة
The present study was carried out under field conditions over two successive winter seasons of 2015/2016 and 2016/2017 on clay loam soil at the Experimental Farm at Shandaweel Agriculture Research Station, Sohag Governorate, Egypt. The aim of this research was to investigate effects of salicylic acid application in combination with foliar spraying with different rates of some microelements (Iron, Zinc and Manganese) on green and seed yield of some pea (Pisum sativum L.) cultivars. Under field conditions of this study, the interaction among Palmoral cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations produced the highest production of green pod yield (ton/fed.) and seed yield (kg/fed.) of pea. Furthermore, the application of interaction among Jaguar cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations gave the highest number of green pods per plant. The interaction among Master B cv., 150 ppm of microelements and 300 ppm of salicylic acid concentrations produced the tallest green pod (cm) and number of green seeds/green pod of pea over both experimental seasons. The highest values of the investigated yield and quality parameters were obtained by the interaction between 150 ppm of microelements and 300 ppm of salicylic acid in the first and second seasons. From results of this experiment, it could be concluded that application of adequate amounts of salicylic acid in combination with foliar application of microelements is one of the most important factors involved in improving yield and quality of pea plants and productivity.

Evaluation of Productivity and Quality of Romaine and Iceberg Lettuce (Lactuca sativa L.) Under Siwa Conditions تقيييم الانتاجية والجودة لخس الرومين والايسبرج تحت ظروف سيوة
The trailswere conducted during two consecutive seasons (2017 - 2018 and 2018-2019) in open field at Siwa Experimental Farm Station, at latitude 29o 12’ N, longitude 25o 29’E and 18 meters below sea level, Marsa Matrouh Governorate, Egypt, to evaluate the effect of three plant density and spraying of two calcium concentrates on growth, yield and quality of two lettuce types grown at winter seasons. Dark green and Mason cultivars represented of both romaine and iceberg lettuce type were transplanted at plant spacing of 25x20, 25x25 and 25x30 cm to give a plant population about 20, 16 and 13 plants per square meter and treated with 300 or 200 ppm of calcium chelate, as well as control treatment. The results indicated that, in spite of decreasing number of marketable heads per plot, low plant density improved average head weight, head diameter, leaf tip-burn, head compactness, as well as enhancement of nutritional value vs, dry matter, Ascorbic acid, potassium and calcium content. Both calcium treatments have a positive effect on lettuce yield and almost quality characters when compared with control treatment, except, average head weight, head diameter, head compactness, leaf tip-burn and dry matter content, dark green as romaine lettuce type produced highest number of marketable heads per planting area, early yield, highest head of water, ascorbic acid, potassium and calcium content. Egyptian market transplanting showed that romaine lettuce type with high density and calcium foliar spray is recommended.

Impact of some Herbicide, Mulches and Their Combinations on Tomato Productivity and Associated Weeds تأثير بعض مبيدات الحشائش وانواع تغطية والتکامل بينهما على انتاجية محصول الطماطم ومکافحة الحشائش المصاحبة.
A field experiment was carried out on 2018/2019 and 2019/2020 at Sids Horticultural Research Farm, Egypt. To study the effect of some herbicide, mulches and their combinations on tomato productivity and associated weeds. A field trial included: a) mulches (rice and wheat straw), b) herbicides (Stomp extra at 1.7 L./fed. and Sencor at 300 g./fed.) either both at full rate alone or at reduced rate 50% of full rate with their integrated by mulches (rice or wheat straw), beside, hand hoeing ,three times and weedy check. A experiment was laid out in a Randomized Complete Blocks Design with three replicates. The results revealed that the all combinations between the two herbicides (Stomp extra at 0.850 L. and Sencor at 150 g./fed.) followed by mulches rice or wheat straw were superior on weed control efficacy than either the herbicides at full rate alone, or mulches alone without any significant differences between all these combinations. But Sencor 150 g./fed. combined with mulching rice straw gave higher weed efficacy than stomp extra combinations with rice or wheat straw in both seasons. It's noticed a positive correlated between weed control efficiency, improving vegetative growth traits and higher tomato fruit yield and its components. Therefore, the combination of Sencor at 150 g./fed. with rice straw can be used as alternative safety methods replaced by either herbicides Sencor and Stomp extra at full rate alone or mulches alone to achieve weed control efficacy without loosing tomato fruit yield, quality and its components.

Agromorphologic Characterization and Molecular Markers of some Teosinte (Zea mexicana) Genotypes الصفات المورفولوجية والمحصولية والمعلمات الجزيئية فى بعض التراکيب الوراثية من الذرة الريانة
Two field experiments was conducted during the summer seasons of 2017 and 2018 to evaluate and identify five teosinte genotypes. A total of morphological characterization depends on stem anthocyanin coloration of sheath of the first leaf (ACS), shape of tip of the first leaf (ShT), wavy surface of blade (WSB), blade attitude of leaf just above upper ear (BAL), anthocyanin coloration of sheath in the middle of plant (ACSh), brace roots(ACBR), fresh anthers and flag leaf angle also, sparse types of spikelet. Values of quantitative traits i.e. fresh and dry yield (kg/plot) and its total, leaf ear width and length, plant height, No. of leaves/plante, No. of tillers and 100 grains weight were varied from trait to other mainly due to genetic background. Molecular marker RAPD analysis polymorphisms among genotypes were detected by five random primers. The high level of polymorphism was occurred with primer OP-C4 which showed 57.1% polymorphism, while the low level of polymorphism was 16.7 % in primer OP-A10. Cluster analysis showed differences between the genotypes which separated into two main clusters, the first cluster was further divided into two sub-clusters (IA and IB), sub-cluster IA Included Balady, Sakha and Dammietta, sub-cluster IB included Gemmeiza3 while, Gemmeiza4 was in a separate cluster. The results of this research of great importance to select the right material which can be used in plant breeding programs as they help for introducing a new variety. Farmer field trails are suggested before the submission of these new varieties to registration testing and its release.

Selection Efficiency and Environmental Sensitivity for Agronomic Traits in A Bread Wheat Population under Normal and Late Sowing Dates Conditions کفاءة الإنتخاب والحساسية للبيئة للصفات المحصولية في عشيرة من قمح الخبز تحت ظروف ميعادي الزراعة العادي والمتأخر
The present study was carried out during seasons, i.e. 2017/18 to 2019/20 at Shandaweel Agric. Res. Stat., Sohag Governorate, Egypt. Two cycles of pedigree selection for grain yield plant-1 and number of spikes plant-1 from F2 to F4 generations were practiced under normal and late sowing dates. The genotypic variance was slightly less than the phenotypic variance under both environments and generally decreased from (F2) to F4 generation. After two cycles of pedigree selection, broad sense heritability estimates were 90.27% and 73.83% for grain yield plant-1 and 88.21% and 82.47% for no. of spikes plant-1 under normal and late sowing dates, respectively. Evaluation of the selected families for high grain yield plant-1 under normal sowing date showed significant differences 18.33% and 9.31% when selection was practiced under normal sowing date, and 20.60% and 11.83% when selection was under late sowing date from the bulk sample and the better parent, respectively. The average observed gains of the selected families for high no. of pikes plant-1 under normal sowing date and evaluated under both conditions were 13.53% and 17.74% from the bulk sample and 9.67% and 11.51% from the better parent under normal and late sowing dates, respectively. While when selection was under late sowing date were 12.68% and 17.80% from the bulk sample and 8.78% and 11.57% from the better parent under normal and late sowing dates, respectively. The antagonistic and the synergistic selection nearly have the same effect on the sensitivity to heat stress under the two selection criteria.

Effect of Different Organic and Mineral Fertilizers on Growth, Yield and Quality of Onion Grown in Sandy Soil under The New Valley Governorate Conditions تأثير الأسمدة العضوية والمعدنية المختلفة على نمو ومحصول وجودة البصل المزروع في التربة الرملية تحت ظروف محافظة الوادي الجديد
The current study was performed at the Research Farm of Faculty of Agriculture, New Valley University during 2017/2018 and 2018/2019 seasons in order to evaluate response of onion cv. Giza 6 to some organic fertilizers, i.e., cattle manure and poultry manure in addition to mineral fertilizers as control treatment. The results obtained showed that the vegetative growth characters and yield components of onion plants were significantly influenced by fertilizers kinds. Combination of poultry manure at 75% of recommended fertilizers and 25% of mineral fertilizers recorded the highest values for both vegetative growth characters and yield components, i.e., plant height, leaves number, plant fresh and dry weight, crop growth rate, bulb fresh weight, bulb diameter, bulb dry matter, marketable yield and total yield in a comparison to mineral fertilizers (control) in both seasons. While, the content of chlorophyll a, b, total carotenoids, N, P and K in onion leaves and vitamin C, sulfur volatile oil and TSS in onion bulb were increased significantly by application of poultry manure at 25% of recommended fertilizers plus 75% of mineral fertilizers compared to mineral fertilizers (control) in both seasons. It can be concluded that application of poultry manure at 75% of recommended fertilizers plus 25% of mineral fertilizers increased growth , yield and improved bulb quality of onion plants cv. Giza 6 under the New Valley Governorate conditions.
