A field experiment was conducted with local strains of phosphobacteria (PSB-S-2) in order to improve the growth and yield of maize in black cotton soil. This PSB isolate performed better with combination of 75 % recommended dose of phosphorus fertilizer with respect to stimulation of beneficial rhizosphere micro flora viz., Bacteria, Fungi, Actinomycetes, Azotobacter and PSB as compared to rest of the treatment combinations. However, it was found on par to 100 % RDP in combination with PSB and 100 % RDP alone. The shoot P concentration was significantly high and it increased with increase in the age of the host due to inoculation of efficient isolate of PSB in combination with 75 % RDP, the plant growth parameters viz., plant height, number of leaves, shoot and root biomass and yield of maize was also found significantly increase over other treatments when it was inoculated with 75 % RDP + PSB.
