Effect of integrated nutrient management on growth and yield of wheat (Triticum aestivum L.)

Abstract

The present investigation entitled “Effect of Integrated Nutrient Management on Growth and Yield of Wheat (Triticum aestivum L.)’’ was carried out at Crop Research Farm of National Post Graduate College, Barhalganj, Gorakhpur, (U P.) During Rabi season on 2023 with the objective to study the effect of Integrated Nutrient Management on growth, yield and quality of wheat (Triticum aestivum L.). The soil of the experimental field was silty loan in texture with low, medium and high in N, P and K respectively. The experimental site is situated in subtropical zone in indo gang tic planes. The experiment was laid out in Randomized Block Design with 7 treatment combinations and 3 replications. Wheat was shown on 11th November 2022 with treatment combinations viz. T1 - Control (R D F 120: 60: 40), T2 - R D F 50% + F Y M 50%, T3 - R D F 50% +Vermicompost 50%, T4 - R D F 50% + Poultry Manure 50%, T5 - R D F 75% + F Y M 25%, T6 – R D F 75% + Vermicompost 25% and T7 - R D F 75% + Poultry manure 25%, respectively. The crop was harvested on 24th March 2023. The result indicated that the treatment combination T6 - R D F 75% + Vermicompost 25% was registered significantly superior in terms of plant height, number of tillers, dry weight, leaf area index, test weight, grain yield, straw yield, gross return (Rs/ ha) and net return (Rs / ha.), respectively over rest of the treatments. Integrated use of organic manures along with optimum doses of chemical fertilizers increased the growth parameters and yield of wheat.
