Effect of foliar nutrient and seed hardening in black gram under irrigated conditions (Vigna mungo L.)

Abstract

Field experiment was conducted at the college field of BFIT Group of Institutions, Dehradun district, Uttarakhand to evaluate seed hardening and foliar nutrition in black gram under irrigated condition during 2020-2021. Ten treatments were included in a randomized block design and replicated three times. The treatments consisted of seed hardening chemicals KCl, KH2PO4, CaCl2, foliar application of DAP, chelated micronutrient and control. The results reveled that seed hardening of KCl, KH2PO4, CaCl2 and foliar nutrition of DAP and chelated micronutrient mixture registered the maximum values for growth and yield parameters of black gram. Seed hardening with 1% KH2PO4 +DAP foliar spray @ 2% and Seed hardening with 1% KH2PO4 + Chelated micronutrient foliar spray @ 0.5% was recommended to get profitably higher yield under irrigated black gram. Higher net income, benefit-cost ratio, eco- friendly and biologically active system were also associated with the seed hardening of 1% KH2PO4 +DAP foliar spray @ 2% that can be supported to the farmers.
