Abstract This investigation was carried out at laboratories of examination and certification of seeds, at the Agronomy Department, Faculty of Agriculture, Assiut University, Egypt during 2019 season to study the impact of storage period, grains treatment and storage methods on quality and yield traits of Gemaza11 cultivar using completely randomized design. The studied traits, were significantly decreased with increasing storage periods till nine months. The lowest mean value test weight (60), seed index (50.33 g), gluten content (10.33%), fermentation time test (30.67 minutes), fine flour percentage (72%), coarse flour percentage (3.333%), coarse bran percentage (20.33%), and fine bran percentage (4.00%). The highest mean values of grain yield feddan-1. Moreover the lowest mean values of grain yield feddan

Abstract Two field experiments were carried out during the agricultural successive seasons (2020/2021 and 2021/2022) in the Agric., Farm of Assiut Univ., Egypt. This investigation aimed to study the effect of spraying methods on two faba bean varieties with different concentrations of salicylic acid (SA) and zinc on the growth and yield. The experiment was designed in split split plot design with three replicates. The first factor included faba bean varieties (Giza 843 and Giza 40) while the second factor included spraying with three concentrations of salicylic acid (0, 100 and 200 ppm. The third factor included two zinc application methods: soil application as Zinc sulphate at a rate of (5 kg/fed) at soil preparing, and foliar application at a rate of 50 mg Zn L-1 of EDTA (13%). Statistical results revealed that Giza 843 variety appeared to be preferred over Giza 40 in all growth and yield parameters. The obtained data indicated that growth and yield parameters increased significantly by increasing SA concentration from 100 ppm to 200 ppm in comparison to the control treatments in both seasons. Data also revealed that both zinc applications methods had a significant effect on growth and yield of faba bean as compared with the control. Also, spraying bean plants by 50 ppm zinc (EDTA) gave the maximum values of growth and yield parameters compared to soil addition with zinc sulphate. The study concluded that the combined foliar application of 200 ppm SA and 50 ppm zinc spray recorded the maximum growth and yield of Giza 843 variety under the conditions of Assiut Governorate.

Abstract Two field experiments were carried out at the Agriculture Research Station of Assiut Research Farm, Faculty of Agric., Assiut Univ., Egypt, for two winter seasons of 2021/2022 and 2022/2023. The aim of this study was to investigate the response of vegetative growth, yield components, and some seed Quality of faba bean (Vicia faba L.) cultivar “Giza 843", to soil application of humic acid and foliar application of chitosan (Ch). Humic acid was applied as soil application at four concentrations (0, 2, 4 and 6 kg/fed twice during growth period. Chitosan (Ch) was foliar applied at 0, 50,100,150 and 250 ppm) four times within growth period. The experiment was designed in split plot design. Humic acid was allocated in the main plot. Meanwhile, chitosan was applied to the sub plot. Results revealed that either humic acid or chitosan highly significantly affected all vegetative growth traits, yield components, and chemical seed quality. Also, combined application of humic acid at a rate of 6kg/fed combined with foliar application of chitosan at 250 ppm recorded the maximum results.

Abstract A field experiment was carried out during 2023 and 2024 seasons at the Agricultural Research Station Experimental Farm in Shandaweel Island, Sohag Governorate to study the effect of spraying soybean (Var. Giza-111) with different concentrations of salicylic acid (SA) and potassium sulphate under different levels of water stress on some vegetative and crop yield characteristics. The experiment was laid out in randomized complete block design (RCBD) using strip plot arrangement within split with three replicates. Three irrigation water amounts (2400, 2000 and 1800 m3/fed/season) were distributed vertically while the four SA concentrations (control, 25, 75, and 100 ppm) were allocated horizontally and, potassium sulphate rate (control, 48 and 72 kg/fed,) as soil applications were arranged in sub plot. The results showed that adding potassium at a rate of 72 kg per fed and spraying soybeans at a rate of 100 ppm had a significant effect on the growth (plant height and number of branches/plant) and soybean productivity (number of pods/plant, weight of 100 seeds, weight of seeds/plant and seed yield/fed). The interaction results showed that adding potassium at a rate of 72 kg /fed. and spraying salicylic acid at a rate of 100 ppm saved the amount of irrigation water from 2400 m3 to 1800 m3.
