The soil in the identified saline area ofAkola and Buldhana district (India) was investigated for the study of nitrogen fixation and phosphate solubilization by bacteria. In the present study 133 samples were analysed from saline affected area of Purna River, among these 22 samples showed the high ability to solubilize the inorganic insoluble phosphate. A total 95 samples showed the fast growing large colonies of Rhizobium strains. From the study it was observed that Rhizobium species have predominant and efficient fast growing large colonies. Also Pseudomonas and Bacillus species have more solubilizing ability of inorganic insoluble phosphate. Application these the isolated strains of Rhizobium species which are fast grower and efficient strains of PSB can be used as biofertilizer as they have local ecology and can tolerate high salt concentration and alkalinity of soil of Akola and Buldhana district of Maharashtra state, India.
