EFFECT OF DUAL BIO-INOCULANTS ON GROWTH, YIELD, ECONOMICS AND UPTAKE OF NUTRIENTS IN CHICKPEA GENOTYPES

A field experiment was conducted during winter seasons of 2009-10 and 2010-11 Rewa (M. P.) to study the effect of dual bio-inoculants on growth, yield, economics and uptake of nutrients in chickpea genotypes. Amongst the chickpea genotypes, JG-130 gave maximum grain (27.04 q ha -1 ) and straw yield (31.89 q ha -1 ) with the net income of `. 92756 ha -1 followed by JG-11 and Vijay. However, the grain protein was highest (24.3 %) in Vijay genotype. Amongst the bioinoculants, Rhizobium + phosphorus-solubilizing bacteria (PSB) recorded the highest grain (30.44 q ha -1 ), straw (34.99 q ha -1 ) yield and grain protein (24.4 %) with the highest net income of `.108079 ha -1 . The second best treatment was Rhizobium + Azotobacter. The yield and net income were further augmented when JG-130 was grown with Rhizobium + PSB. The uptake of N, P, K and S was significantly higher in grain and straw of JG-130 over JG-11 and Vijay. The nutrients uptake by grain and straw was significantly higher due to Rhizobium + PSB over the single bio-inoculants. The highest total nutrients uptake by chickpea, due to Rhizobium + PSB, was 151.4 kg N, 18.0 kg P, 71.9 kg K and 18.1 kg S ha 1 .
