A field experiment was conducted in kharif 2011on blackgram genotype T-9. The experiment was laid out in randomized block design with three replication and thirteen treatments. There was significant improvement recorded in yield, nutrient content, uptake and physico-chemical properties viz. pH, electrical conductivity, organic carbon and available N and P of soil under black gram crop. Grain yield was increased by 47.06% in treatment T13 over control while, organic carbon showed significantly highly positive correlation with available nitrogen (r=.878) in post harvest soil. However, combination of rhizobium, PSB and P levels had proved significant influence on yield, content, uptake of nutrient and physico-chemical properties of soil under blackgram. Furthermore, inoculation of rhizobia and PSB into the soil found beneficial to increase the availability of native fixed phosphate and to reduce the use of fertilizers and build up significant improvement in residual soil fertility.
