Effect of Some Climatic Conditions and Some Fertilization Treatments on Productivity Quality of Bean Plants As Weii As Their Relationship with Rust Disease

Abstract

The present study was conducted at a private farm in El-Khatateba -Sadat City-Menofyia Governorate location during 2019/2020 and 2020/2021 to evaluate the effect of foliar spraying with some organic fertilizers (green organic magic, green power and compost tea on growth, seed yield and seed quality of three dry beans cultivars (Giza 6, Giza 10 and Nebraska), as well as the impact of those fertilizers on the severity of the three cultivars of rust diseases. The obtained results showed a wide diversity among all tested cultivars in growth, yield and quality traits. All bean studied traits significantly affected by the differences organic fertilizer treatments in both seasons. Giza 6 cv. had the highest number of pods/plant, number of seeds/pods, number of seeds/plant and seed yield/fad in addition to the lowest percentages of disease severity and disease incidence of rust, in both seasons. Nebraska cv expressed the highest number, 100-seed weight as well as seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that treated with Green power gave the highest; number of pods/plant, number of seeds/plant, 100-seed weight, seed yield/fad and the highest seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that sprayed with Green power recorded the lowest disease severity and disease incidence and this reduction in both severity and incidence associated with the highest efficacy of disease reduction in both seasons. As for the interaction Giza 6 cv that treated with Green power had the highest; number of pods/plant and seed yield/fad in both seasons. Giza 6 cv that sprayed with Green organic magic recorded the lowest disease severity, disease incidence and the highest efficacy of disease reduction in both seasons. Nebraska cv that treated with Green power had the highest seed contents of moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. The results confirmed that seed yield/fed significant negative associated with rust disease severity
