A field experiment was conducted during two consequentive years (2015-16 and 2016-17) at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur-2 to assess the residual effect of organic and inorganic fertilizer sources of N on growth and productivity of succeeding wheat (Triticum aestivum L.) crop. The experiment was conducted in split plot design involving 5 and 4 treatments of N through organic inorganic secondly respectively. The results expressed maximum plant height, dry matter accumulation, yield attributes, wheat and Straw yield with the application of organics, followed by vermicompost and FYM each @50% RDN and which were found superior to lower does. The maximum uptake of NPK by wheat was recorded with organic application. The system productivity of wheat, net returns and cost: benefit ratio were favourably influenced by different sources of organics and fertilizer N when applied at different levels to wheat. Under organic sources of nutrient, maximum mean gross and net return values of wheat was significantly recorded under FYM @ 50% RDN (₹ 116315 and 72115/ha), followed by FYM @ 25% RDN (₹ 112905 and 68705/ha) and vermicompost @ 50% RDN (₹ 110434 and 66234/ha), respectively.
