Abstract :

Sustainable agriculture is reliable, acceptable and trustworthy way to maintain a healthy soil and thus to produce good quality and quantity of food. To achieve this task there is often use of biofertilizers which contain nitrogen, phosphorous and potassium as major nutrient. Soil is living entity contain variety of Macronutrients and Micronutrients. Phosphate is one of the major nutrients required by plants but not easily available to them because of its insoluble nature. Phosphate solubilizing bacteria (PSB) make it soluble thus play important role in sustainable agriculture. The use of PSB as a biofertilizers has concurrently increase phosphorus uptake in plants and improve yields in several crop species. A laboratory study has conducted to isolate, identified and characterize the phosphate solubilizing bacteria from different soils of Vidarbha region, four isolates were obtained from four districts respectively. The four strains (S1, S2, S3 and S4) were screened by biochemical study and their phosphate solubilizing ability helps in plant growth.
