Phosphate-Solubilizing Microorganisms Isolated from Rhizosphere of Orange Crop in Katol Tahsil

Present study deals with morphological characteristics of PSB colonies in rhizosphere of orange crop in Katol Tahsil. . Seventeen soil samples were taken from rhizospheres of orange crop. Phosphate-solubilizing bacteria ( PSB ) were isolated on Pikovskaya's (PKV) agar. Morphological characteristics of Colony's ( size, edge, form, elevation, and color ) were measured, and their phosphate solubilization values were calculated. Total twenty samples of phosphatesolubilizing bacteria were isolated from various orange fields.
