abstract
A field experiment was undertaken at AICRP on Integrated Farming System, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to assess the “Effect of foliar application of nitrogenous fertilizers on growth attributes, soil properties, quality and productivity of wheat (Triticum aestivum L.)” during Rabi season of 2023-2024. The experiment was conducted in randomized block design (RBD), replicated thrice with ten different treatment combinations were used in the experiment which includes T₁ – Absolute control, T₂ - RDF (120:60:60 kg NPK ha^-1), T₃ - 25% RDN + 100% RDPK + Three foliar sprays of nano urea at 30, 45 and 60 DAS, T₄ - 50% RDN + 100% RDPK + Two foliar sprays of Nano Urea at 45 and 60 DAS, T₅ - 75% RDN + 100 % RDPK + One foliar spray of Nano Urea at 45 DAS, T₆ - 25% RDF + Three foliar sprays of Nano Urea at 30, 45, and 60 DAS, T₇ - 50% RDF + Two foliar sprays of Nano Urea at 45 and 60 DAS, T₈ - 75% RDF + One foliar spray of Nano Urea at 45 DAS, T₉ - Three foliar sprays of 19:19:19 NPK liquid fertilizer at 30, 45 and 60 DAS and T₁₀ - 100% RDPK + Three foliar sprays of Nitrate Nitrogen at 30, 45 and 60 DAS. The results emerged out indicated that plant height, number of tillers, leaf area, chlorophyll content, test weight, grain and straw yield also quality parameters such as protein and carbohydrate content of wheat was recorded highest with treatment of (75% RDN + 100% RDPK + One foliar spray of Nano Urea at 45 DAS). Significantly higher value of soil available N, P and K were recorded after harvest in treatment receiving (75% RDN + 100% RDPK + One foliar spray of Nano Urea at 45 DAS). The effect of foliar application of nitrogenous fertilizers on soil pH, EC, Organic Cardon and Calcium Carbonate and on DTPA extractable micronutrients in soil after harvest was found non-significant.
