Effect of Integrated Nutrient Management on Growth and Yield of Wheat (Triticum aestivum L.) in Sandy Soil of West Bengal

The influence of nano urea as foliar spray along with split application of potassium was studied on wheat cv. DBW 187 (Karan Vandana) during 2022–2023 at Seacom Skills University, Birbhum, West Bengal. The maximum plant height, more dry matter production, more number of tillers per m² were observed in treatment with Basal dose of50:60:20 kg NPK/ha and foliar spray with 0.5% Nano Urea and 1 % MOP solution at Crown root initiation and Flag Leaf stage. The same treatment showed highest number of spikes/m², spike length, filled grains/spike, test weight, grain yield and straw yield as well. Soil enzymatic activity was maximum in RDF with split potassium doses. The gross returns, net returns and benefit: cost ratio too were maximum in the same treatment. Hence, a basal dose of 50:60:20 kg NPK/ha and foliar spray with 0.5% Nano Urea and 1% MOP solution at CRI and Flag Leaf stage was beneficial for wheat production in the Red and Lateritic soils of West Bengal, keeping soil health in view.
