A field experiments on Indian bean green pod yield was assessed for effectiveness of inoculation with biofertilizer sunder various levels of phosphorus application. The data revealed that inoculation significantly increased the Indian bean pod yield at all levels of phosphorus application including control. Application of 50 kg P/ha along with PSB + VAM + Rhizobium inoculation maximized Indian bean pod yield (43.67 q/ha) which was 42.67 % higher and significantly better than the yield obtained at same level of P application without biofertilizer inoculation. However, yield obtained with 50 kg P/ha (43.67 q/ha) was statistically at par with that of 50 kg P/ha with or without biofertilizers, 37.5 kg P/ha with VAM, Rhizobium and PSB + VAM + Rhizobium. Higher value yield, phosphorus use efficiency and apparent nutrient recovery were optimized under inoculation with PSB + VAM + Rhizobium as compared to non-inoculation. The results depicted the beneficial effects of PSB + VAM + Rhizobium inoculation on Indian bean pod yield resulting in saving of 6.50 to 14.70 kg/ha phosphorus and an enhanced pod yield ranging from 26 to 44 q/ha
