Effect of Integrated Use of Mineral, Organic N and Azotobacter on the Yield, Yield Components and N-nutrition of Wheat (Triticum aestivum, L.)

Mohammad Idris

Abstract:
The effect of mineral N, organic N and Azotobacter alone and in various combination was investigated on the yield and N nutrition of wheat in an experiment. The results revealed that mineral, organic fertilizers and Azotobacter applied alone and in various combinations significantly improved the yield, yield components and N uptake by wheat crop as compared to control. The effect of fertilizers treatments in improving the biomass yield of wheat was statistically higher (P 0.05) as compared to mineral N or produced biomass yield statistically (P 0.05) at par with mineral N applied at 60 mg kg-1 soil. Mineral N (30 mg N kg-1 soil+ Azotobacter ) organic N (30 mg N kg-1 soil+ Azotobacter) and organic N (60 mg kg-1 soil) resulted in significantly ((P 0.05) lower biomass yield as compared with mineral N applied (60 mg kg-1 soil). Azotobacter of wheat alone also produced lower biomass yield as compared to mineral N applied at 60 mg kg 1 soil. Application of mineral N, organic N and Azotobacter alone and in various combinations either improved statistically (P 0.05) or produced an equivalent N uptake response as compared to mineral N applied at 60 mg kg 1 soil. Azotobacterization alone did not produce any significant improvement in biomass N uptake as compared to mineral N applied at 60 mg kg-1 soil. At last 50% of mineral N can be saved as a result of judicious combination of mineral N, organic N and or biofertilization of wheat with Azotobacter while obtaining an equivalent or higher biomass yield as compared to mineral N applied at 60 mg kg-1 soil.
