Limited availability of phosphorus (P) in agricultural soils is a major cause of poor growth and yield of crops throughout the world. Optimization of crops productivity can be achieved by increasing the bioavailability of P via phosphate solubilizing bacteria (PSB), however, their effectiveness may vary with changing agro-climatic conditions That’s why current experiment was conducted to evaluate the poten- tial of phosphate solubilizing bacteria (with PSB and without PSB) in improving growth and yield of wheat under different P levels (0, 25, 50, and 100 % of recommended P). The PSB with 100% recommended P significantly enhanced wheat tillers m—2, grains spike-1, grains and biological yield compared to the rest of the treatment’s combination. A significant improvement in 100 grains weight and rate of photosynthe- sis also validated the efficacious functioning of PSB and full recommended P. Furthermore, PSB were effective in optimizing wheat yield attributes at respective P level compared to Without PSB. Our findings imply that, PSB application along with 100% recommended P as inorganic phosphorus has potential to enhance wheat growth and yield over sole application of P fertilizers or PSB.
