Abstract

ABSTRACT: Okra is a summer season vegetable crop, grown for its tender pods. For the environment friendly and sustainable cultivation of okra, the replacement of chemical fertilizers with the appropriate amount of bio-fertlizers may prove useful. In order to investigate the effect of various combination of chemical and bio-fertilizers on the growth and yield of okra, a field experiment was conducted at the experimental farm of Faculty of Agricultural Sciences, DAV University, Jalandhar during the summer season of 2019. The field experiment was laid out in randomized block design with three replications and ten treatments, comprising of chemical and bio-fertilizers viz. T1 control, T2 [Recommended dose of fertilizers (RDF) of Azosprillium spp. + 50% N + 100% P and K], T3 (50% Azosprillium spp. + 75% N + 100% P and K), T4 (Azotobacter spp. + 50% N + 100% P and K), T5 (50% Azotobacter spp. + 75% N + 100% P and K), T6 [50% Phosphorous solubilizing bacteria (PSB) + 50% P + 100% N and K], T
