The effective nutrients management is requiring for increase the productivity and development of cowpea crop as suitable agronomic practice. A field experiment was conducted during the two summer seasons of 2018 and 2019 at Sakha Agricultural Research Station Farm, Kafr El-Sheikh Governorate, Egypt on cowpea (Vigna unguiculata L.) cv. Kafr El-Sheikh to study the impact of organic and inorganic fertilizers and foliar spray with K, Ca and B and their interactions on vegetative parameters, seed yield and leaf chemical composition as well as protein content and seeds germination percentage. Results indicated that, the highest values of vegetative growth parameters i.e., plant height (cm), No. of branches/plant, plant fresh and dry weights and chemical composition of leaves (N, P, K, Ca and B), as well as the percentage of protein and germination seeds were recorded by fertilized plants with 50% mineral + 50% organic (compost). Cowpea plants were sprayed with 1cm/l potassium sulfate showed better growth performance, higher values of chemical constituents especially N, P and K in leaves than unsprayed plants. Also, the best results on most growth parameters, leaves chemical constituents were resulted when plants were fertilized by 50% mineral as ammonium nitrate (50 kg/fed.) + 50% organic as compost (1.2 or1.3ton/fed.) and sprayed with potassium sulfate at 1cm/l. Therefore, this treatment could be recommended for improving cowpea plants performance under similar condition of this study.

The present investigation aimed to study the impact of water stress on three quinoa cultivars namely; quinoa 1, rainbow and American cultivar. Where, the three quinoa cultivars rated as various reactions for water deficit tolerance and were evaluated under the control and water stress conditions during two growing seasons. Some agro-morphological and physiological traits associated with water stress tolerance were measured under both conditions during the two seasons. Also, heritability in broad sense, PCV %, GCV %, D Z , GA and GAM % were the most important genetic parameters calculated for all studied traits under the same conditions during the two growing seasons. Water deficit tolerance indices were a fruitful and fertile test used to determine the various tolerance degrees of drought stress in the three quinoa cultivars for the traits; number of branches/plant, number of leaves/plant, 1000-seeds weight and seed yield/plant in both years. Five polymorphic protein bands out of six produced (83.3%) of polymorphism which indicated the genetic variations of three quinoa cultivars under water stress. The three quinoa cultivars were able to prove that they are varied tolerant to water stress, depending on the results of all studied traits, especially yield and its components, root and physiological traits namely; proline, glycine betaine and trehalose contents. Where, the cultivar quinoa 1 was coming at the first place as a tolerant, followed by rainbow and then followed by the American cultivar as a moderate to sensitive. In any case, the three quinoa cultivars recorded a good and satisfactory yield under water stress conditions compared to the standard experiment in parallel of the results of roots and physiological attributes represented in proline, glycine betaine and trehalose contents production which were excellent under stress compared to the control conditions. Using SCoT primers, there were high genetic diversity and generated 131 fragments where 89 of them were monomorphic besides, 42 polymorphic bands with 32.06 % polymorphism. In addition, detected 42 specific markers (17 positive and 25 negative) as genetic markers used at the molecular level to identify quinoa cultivars that are tolerant to water stress over those that are moderately to sensitive. Changes in isoenzymic were studied using PAGE under nonreduced, non-denatured conditions at 4 _C. Native PAGE analysis was performed for various enzymes involved in the ascorbate–glutathione cycle on a gel (10%) with protein load of 50 lg in each well. Specific procedures for running and staining of gels for different enzymes are given below. Staining of gels SOD activity. Gels were soaked NBT solution potassium
