Abstract:

A field experiment was conducted during kharif, 2015 at College of Agriculture, V. C. Farm, University of Agricultural Sciences, Bangalore. The experiment comprised of thirteen treatments consisting of three levels of phosphorus (75, 100 and 125% of recommended dose) and various phosphorus biofertilizers and Plant Growth Promoting Rhizosphere (PGPR) and their combinations. The experiment was laid out in RCBD with three replications. The type of soil was sandy loam. The maize hybrid used was NAH-1137. The results revealed that, the application of 75, 100 and 125% of recommended dose of phosphorus fertilizer along with PGPR II (Pseudomonas fluorescens + Bacillus megaterium + Azospirillum brasilense) improved the soil nutrient status as well as biological properties of the soil by increasing the population off beneficial microbe in the soil. The population of free-living N-fixers and phosphate fixers were higher with T4, T8 and T12. This has also resulted in increased kernel and straw yield in these treatments.
