ABSTRACT:

In the present study isolates of phosphate solubilizing bacteria were isolated from agriculture soil of Bathnaha Village under Saharsa district. Altogether six isolates were isolated from soil out of which two belong to Azotobacter chroococcum, one belongs to Pseudomonas fragi and three belong to Bacillus subtilis. Isolates were cultured is PVK medium and Solubilizing efficiency (SE) and Solubilizing Index (SI) were calculated on the basis of Halozone and colony diameter. SE varied from 10.49 to 12.29 and SI varied from 4.309 to 4.598. Maximum value at SE and SI was recorded for isolate no. 6 at Bacillus subtilis.
