A field experiment comprised fertility levels (control, 50% RDF, 75% RDF, and 100% RDF) and biofertiliizers levels (control, PSB, Rhizobium and Rhizobium + PSB) were applied to the black gram var. T-9. The application of fertility level and seed inoculation with Rhizobium + PSB significantly increased in number of pods plant-1, number of seeds pod-1, the number of total and effective root nodules plant-1 at 60 DAS and microbial population. The application of 50% RDF, 75% RDFand 100% RDFtreatments increased number of bacterial population (6.59, 15.89 and 19.93%), fungal population (24.62, 35.09 and 41.57%), actinomycetes population (16.60, 33.62 and 41.08%) in soil at 0–15 cm depth, respectively over control and in soil at 15–30 cm depth to the extent of bacterial population (6.18, 15.42 and 19.45%), fungal population (8.48, 21.31 and 25.43%), actinomycetes population (21.45, 21.92 and 40.36%), respectively over control. The increase of bacterial population (21.18, 20.96 and 26.61%), fungal population (4.47, 6.99 and 11.59%), actinomycetes population (26.62, 28.54 and 42.79%) in soil of black gram with PSB, Rhizobium and Rhizobium + PSB inoculation was in soil at 0–15 cm depth, respectively over control and in soil at 15- 30 cm depth to increase the bacterial population (35.75, 35.52 and 54.34%), fungal population (12.86, 14.04 and 21.66%), actinomycetes population (7.59, 11.31 and 15.43%), respectively over control. However, test weight was found non significant.
