Title: Effect of bio-fertilizer and chemical fertilizer application on nutrtent uptake and yield in wheat (Triticum aestivum L.)
Abstract: The grain and straw yield and nutrient (N and P) uptake in wheat increased significantly on inoculation with NFB, PSB, their co-inoculation and combination with chemical fertilizer over non-inoculated control. The co-inoculation of PSB and NFB proved beneficial in enhancing the grain and straw yield and nutrient uptake per hectare over either of the inoculants alone and uinoculated control showing synergistic erfect. The NFB inoculation recorded about 26–27% increase in grain yield whereas PSG noculation enhanced 15–16% increase in grain yield over non-inoculated control. The increase in the nutrient (N & P) uptake by grain and straw may be attributed to higher availability of Nand P to plants from the soil with addition of bio-fertilizer and chemical fertilizer and the increase in the yield production. The N uptake by grain and straw with NFB inoculation and N chemical fertilizer was generally more than PSG inoculation and phosphate fertilizer application but further increase in N uptake was recorded on addition of phosphate through chemical fertilizer or PSB inoculation which could be attributed to higher yield with phosphate addition and similar trend for P uptake by grain and straw with PSB inoculation and phosphate fertilizer application was recorded with further rise in P uptake on addition of N chemical fertilizer or NFB inoculation. There was recorded the saving of about 25 kg N ha-1 and 15 kg P2O5 ha-1 by inoculation with Azospirillum brasilense and Bacillus polymyxa, respectively.
