Abstract: 

The phosphate solubilizing bacteria were isolated from the rhizosphere soils of Cotton, Brinjal, Bhendi, Tomato and Cluster bean. Two PSB isolates from each crop plants totally 10 PSB strains were isolated for further studies. The isolated PSB were identified by their morphological and biochemical properties. The isolated PSB strains were characterized under in-vitro by measuring the P solubilization zone in solid medium, phosphate solubilizing index, determining pH change of the medium and estimating the organic acid production, phosphates activity and available phosphorus. Among ten strains, the BP1 strain was superior in pH reduction, organic acid production, phosphatase activity and more in P release.
