Abstract— It was noted from the present study that the maximum grain yield and fresh biomass yield 2799 kg ha-1 and 10373 kg ha-1 respectively was recorded in treatment-3 with application of Bio-fertilizer (AzospirillumA1-Q) + N 45kgha-1 and P2O5 30kgha-1.Whereas, minimum grain yield and fresh biomass yield 1340 Kg ha1 and 6783 kg ha-1 respectively was noted in treatment-1 (control). Both grain and biomass yield increased due to increase in number of tillers, grain weight and suitable Nitrogen fixation, showing positive effect of mineral fertilizer (Biomass yield= Clipping of crop before heading stage for fodder purposes). The results proved that application of bio fertilizer in combination with N 45 kg ha-1 and P2O5 30 kg ha-1 increased 100% grain yield and 52% fresh biomass yield as compared to the treatment-1 (control).
Keywords— Wheat, Bio-fertilizer, nitrogen, phosphorous, yield components.
