1,2 Effect of bacterial inoculation on wheat growth and yield parameters, P uptake and soil nutrients at 35 days after sowing (DAS) and at 120 DAS in a pot experiment at Faisalabad grown wheat during winter season 2018–19. Control 80% and Control 100% represent non-inoculated controls supplemented with 80% of the recommended dose of P fertilizer and full recommended dose of P fertilizer, respectively. PSB (1 × 109 CFU ml–1) were seed-inoculated before sowing. Inoculated pots were supplemented with 80% of recommended dose of DAP fertilizer. Means are the average of six biological replicates arranged in CRD. Means followed by the same letter differ non-significantly at p = 0.05 according to LSD. ± Represents the standard deviations (SD). Six plants were grown in earthen pots (diameter: 12 in, height: 14 in) containing 12 kg soil.
