The aim of the study was to isolate phosphate solubilizing bacteria from soil and investigate their potential for plant growth promotion. Most of the bacteria were isolated from soil sample with pH values close to 6.8-7.2. There is a close relationship between the phosphate solubilizing activity and low pH levels growth medium. The bacterial isolates were identified as belonging to the following genus Pseudomonas sp., Bacillus sp., Rhizobium sp., Azotobactersp. and named as PSB1, PSB2, PSB3 and PSB4. The pot culture experiment was conducted to study the effect of T1 – Control (with out inoculums), T2 – Control + PSB, T3 – Control + FYM, T4 – Control + PSB + FYM for the enhancement of growth of Chilly (Capsicum annuum L.) plant by recording plant height, shoot length, Rootlength, Leaf lengthand Dry Weight. In general, plant growth was better in T2 –PSB treated pot. The PSB treated Capsicum annuum L. plant were showed better growth than T3 & T4.
