Evaluation of Different Microbial Inoculum on Mung Bean (Vigna radiata L.) Growth, Development and Nutrient Availability

Abstract

A field experiment was conducted on Mung Bean (Vigna radiata L.) during the autumny season of 2020-21 at Technology Park of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The experiment was laid out in randomized complete block design (RCBD). Results revealed that the growth parameters of mung bean viz., number of (331229 plants/ha), plant height (67.7 cm/plant), trifoliate leaves/plant (12.7), number of branches/plant (4.5), dry matter accumulation (18.7 g/plant), leaf area index (5.72), CGR (7.6 g/m2/day) 50-at harvest and grain yield of (1,106 kg/ha) improved by various treatments over control, being highest under NPK Consortia+ZSB, each @ 20 ml/kg. Similarly, this treatment also produced an accumulation of 59.8% more dry matter/plant than control. However, application of NPK Consortia+ZSB, each @ 20 ml/kg recorded higher available N, P, K and Zn followed by NPK Consortia @ 20 ml/kg and RDF (20:40 kg/ha).
