Impact of integrated nutrient management on growth and yield of wheat (Triticum aestivum L.) under the agro-climatic conditions of southern Uttar Pradesh

The present investigation entitled “Effect of Integrated Nutrient Management on Growth and Yield of Wheat (Triticum aestivum L.) Under Agro-Climatic Conditions of Southern Uttar Pradesh” During Rabi season on 2023- 24 with the objective to study the to assess the effect of different nutrient treatments on the growth and development of wheat. 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 9 treatment combinations and 3 replications. Wheat was shown on 11th November 2023 with treatment combinations viz. T1 - Control (Farmer practices) T2 - 100% RDF (120:60:40 NPK kg/ha), T3 - 75% RDF + 10 t/ha FYM, T4 - 75% RDF + 5 t/ha Poultry Manure T5 - 75% RDF + 2 t/ha Vermicompost, T6 - 75% RDF + 10 t/ha FYM + 5 t/ha Poultry Manure T7 - 50% RDF + 5 t/ha Poultry Manure + 2 t/ha Vermicompost T8 50% RDF + 2 t/ha Vermicompost + 10 t/ha FYM T9 50% RDF + 10 t/ha FYM +5 t/ha Poultry Manure + 2 t/ha Vermicompost. The crop was harvested on 5 th April 2024. The result indicated that the treatment combination T6 - 75% RDF + 10 t/ha FYM + 5 t/ha Poultry Manure was registered significantly superior in terms of Number of earhead per m2, Number of grains per earhead, weight of ear head, Length of earhead (cm), 1000 grain weight (g), Grain Yield (kg/ha), Straw Yield (kg/ha), Biological Yield (kg/ha) Harvest Index (%) 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.
