Abstract: An experiment was conducted to study the effect of farm yard manure, vermicompost and inorganic fertilizers on wheat nutrient content and uptake conducted during the rabi season of 2017-2018 at Experimental site of Agroforestry Research Centre (old site) near Horticulture Research Centre, Patharchatta of G.B. Pant University of Agriculture and Technology, Pantnagar. The soil of the experimental site belonged to Makota-III clay loam as surface texture, neutral in reaction, low in nitrogen, medium in available phosphorus and potassium but high in organic carbon. The experiment was laid out in Randomized Block Design replicated thrice with nine treatments viz. T1 (Open Control), T2 (Control under poplar agroforestry), T3 (100% RDF), T4 (100% RDN through FYM), T5 (100% RDN through VC), T6 (50% RDN through FYM + 50% RDN through urea), T7 (50% RDN through VC + 50% RDN through urea), T8 (50% RDN through FYM + 50% RDN through VC) and T9 (50% RDN through organics (25% FYM + 25% VC) + 50% RDN through urea). Four irrigations were given at different critical stages of the crop including a pre sowing irrigation. Results showed that T9 and T7 significantly influenced the N, P and K content and its respective uptake in grain and straw as well as in wheat yield. Difference between two controls T1 and T2 were also noted on yield basis due to incorporation of leaf litter of poplar in T2.
