Abstract
The use of phosphorus solubilising bacteria (PSB) as seed or soil inoculants can potentially enhance P uptake by plants and thereby enhance crop yields. 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 (0, 25, 50, and 75 kg P₂O_­5 ha^-1 as ammonium phosphate) and three inoculation rates i.e. 0, 100 and 200 g per 50 kg seed, of Barvar 2 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 2) along with lower rate of mineral phosphorus (25 kg P₂O₅ ha^-1) 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.
