Effect of Foliar Application with Nano-Micronutrients and Organic Fertilization on Snap Bean under Sandy Soil Condition

Abstract

Nanotechnology presents brilliant agricultural products, which may be an achievement in addressing many common economic and ecological issues. Nano-fertilizers show special characters which do not exist in their conventional counterparts. So; this work conducted out during 2019 and 2020 seasons to investigate the effects of three forms of micronutrient Fe + Zn in foliar way (nano, EDTA and sulfate) under organic fertilization (without, chicken manure and FYM) on vegetative growth, physical, chemical and quality of pods and green yield of snap bean as well as some chemical properties of soil after harvesting. All treatments under investigation had significant effect on vegetative growth (plant height, number of branches, fresh, dry weight and chlorophyll content), pod physical quality (number, length, weight and diameter), green pod yield,nutritional value of snap bean leaves and pods (N, P, K%, Fe and Zn mg.kg-1), pod chemical quality as (protein, total carbohydrates, fiber and TSS%) and soil analysis after harvest ( available N, P, K FC and S.P). The results in this study showed that, applying chicken manure and foliar application with nano Fe + Zn was the most suitable treatment significantly affected in all mentioned parameters comparing with the other treatments.
