Abstract: An experiment was conducted during rabi season in 2017-18 and 2018-19 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to study the Effect of integrated nutrient management on yield of wheat (Triticum aestivum L.) under in Indo-Gangetic Plains. The experiment was laid out in randomized block design with fourteen treatment of nutrient management viz., Control (T-1), Recommended NPK (T-2), FYM@ 5t/ha+Recommended NPK(T-3), Recommended NPK+Bio-stimulant-G 25Kg/ha (T-4), Recommended NPK +Bio-stimulant-L@ 625ml/ha foliar spray each at 40,55&70 DAS (T-5),Recommended NPK and foliar spray of NPK-P 1% and Bio-stimulant-L @ 625 ml/ha at 70 DAS (T-6),FYM @5 t/ha+ Recommended NPK+ Bio-stimulant-G 25kg/ha (T-7),FYM @ 5 t/ha+NPK-G@ 200 kg/ha+ NPK-Biofertilizer+Urea@ 20 kg/ha at 40 &55 DAS (T-8), FYM@ 5t/ha+NPK-G 200kg+Bio-stimulant-G 25kg/ha+ Urea @ 20kg/ha at 40 &55 DAS (T-9), FYM @5t/ha+ NPK-G 200 kg/ha +NPK Bio fertilizer+Urea and foliar spray NPK-P @ 1% at 55 &70 DAS (T-10),FYM@ 5 t/ha+ NPK-G@ 200kg/ha+ NPK-Bio fertilizer+NPK-P @ 1% foliar spray (T-11), FYM @ 5t/ha+ NPK 200 kg/ha + NPK-Bio-fertilizer+ Urea @ 20 kg/ha basal &40 DAS and foliar spray Bio-stimulant-L 625ml/ha (T-12), FYM @5t/ha+ NPK-G @200 kg/ha + NPK-bio fertilizer + Urea and foliar spray of NPK-P &Bio-stimulant –L at 40,55& 70 DAS (T-13), FYM @5t/ha+ NPK-G @200 kg/ha + NPK-bio fertilizer and foliar spray of NPK-P &Bio-stimulant –L at 40,55& 70 DAS (T-14) were laid out in RBD and replicated thrice taking wheat var. DBW -71 as test crop. The maximum growth parameter viz.,plant population in running meter, plant height (cm),numbers of tillers in running meter and dry matter accumulation (g per running row length) were recorded with the application of (T-14) FYM @5t/ha+NPK-G @ 200kg/ha+ NPK-bio fertilizer+Urea @20 kg/ha and foliar spray NPK-P@ 1% & Biostimulant –L 625ml/ha at 55 &70 DAS which was at par with the application(T-13) FYM @5t/ha+NPK-G @200 kg/ha +NPK-bio fertilizer and foliar spray NPK-P @1% & Biostimulant-L 625 ml/ha at 40, 55 & 70 DAS.Which was significantly superior over all treatments at all stages of observations. The improvement in yield attributes and yield of crop was recorded with the application of (T-14) FYM @5t/ha+NPK-G @ 200kg/ha+ NPK-bio fertilizer+Urea @20 kg/ha and foliar spray NPK-P@ 1% & Biostimulant –L 625ml/ha at 55 &70 DAS and lowest yield attributes and yield was recorded in control.
