1, 2Effect of bacterial inoculation on various wheat growth parameters at 35 days after sowing (DAS) and at 120 DAS in a pot experiment.
Control 80% and Control 100% represents non-inoculated controls supplemented with 80% of the recommended dose of P fertilizer and full recommended dose of P fertilizer, respectively. Pseudomonas sp. MS16 and Enterobacter sp. MS32 (1 x109 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 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). Plants were grown in earthen pots (Diameter: 12 inch, Height: 14 inch) containing 12 Kg soil. Three plants were grown per pot.
