A field study was conducted to investigate the effect of integrated use of PSB and chemical phosphate fertilizer on P uptake and grain yield of wheat (Triticum aestivum L., cv. Chamran). Fertilizer treatments comprised four levels of chemical fertilizer (۰, ۲۵, ۵۰, and ۷۵ kg P۲O۵ ha-۱ as ammonium phosphate) and three inoculation rates i.e. ۰, ۱۰۰ and ۲۰۰ g per ۵۰ kg seed, of Barvar ۲ biofertilizer containing P solubilising bacteria (Pseudomonas putida and Pantoea agglomerans). An increase in grain yield and P uptake was found with the increasing rate of mineral phosphorus. Inoculation of bio-fertilizer (Barvar ۲) along with lower rate of mineral phosphorus (۲۵ kg P۲O۵ ha-۱) produced maximum grain yield and accumulated maximum phosphorus in grain. There were significant treatment interactions, with evidence of antagonism between P fertilizer and PSB inoculation at their highest rates, particularly in case of grain yield, P uptake and harvest index. Key words: Biofertilizer, Grain yield, Phosphorus uptake, Wheat.
