Abstract
We investigated the effect of co-inoculation of Rhizobium with Phosphate Solubilizing Bacteria (PSB) in green gram under pot experiment in alluvial soil during Zaid season of 2015-16. Five treatments along with one un-inoculated control treatment were examined with three replications under Completely Randomized Block Deign experiment. It have been concluded from the study that the seed inoculated with Rhizobium sp.@20 g kg-1 seed + PSB @20 g kg-1 seed + 75 % RDF significantly increased nodule number by 79.13% and 33.41 % over un-inoculated control treatment and application of PSB alone + 100% RDF. The similar results were also found for shoot dry weight for the rest four treatments by 40.02%, 22.04%, 12.88% and 13.0% when compared to control one. As evident from the results, the co-inoculation of Rhizobium sp. and PSB also increased the soil microbial biomass carbon than that of absolute control.
