Response of Azospirillum and Bacillus on growth and yield of wheat under field conditions

Wheat Seeds of cv. HD 2428 and DL 153-2 inoculated with Azospirillum brasilense and Bacillus subtilis were sown under field conditions. The use of both the biofertilizers enhanced leaf area, chlorophyll concentration, NR activity, total biomass production and grain yield. The cultivar DL 153-2 had given higher response to inoculation than HD 2428. The analysis of grain revealed that P and K uptake were enhanced when inoculated with Bacillus subtilis whereas N uptake was more with Azospirillum brasilense.
