Phosphorus is a second most important nutrient in soil for crop production and there is no large atmospheric source that can be made biologically available. Large amount of P applied as fertilizer (DAP, SSP, DSP and TSP etc) enters in to the immobile pools through precipitation reaction with highly reactive Al3+ and Fe3+ in acidic condition, and Ca2+ in calcareous or normal soil. A field experiment was conducted at farmer field, during kharif season with different treatments of PSB combination of different fertilizers. The results of this study showed that the application of PSB with phosphoric fertilizer gave higher effects on growth and yield of maize. PSB increase the solubility of phosphate in soil and enhance the plant growth by improving biological fixation. Application of PSB will help in reducing the 30-40 % conception of P fertilizer. In environmental point of view, control soil and water pollution and also balance the physical, biological and chemical soil fertility with application of low P fertilizer and PSB.

Key words: Phosphorous, PSB, Fertilizer, Biofertilizer, Vertisol
