A field experiment was conducted at Deendayal Research Institute Krishi Vigyan Kendra Chitrakoot UPto assess the residual impact of Integrated Nutrient Management and direct effect of inorganic fertilization on Wheat (Triticum aestivum) for yield attributes, yields, nutrient uptake and economics during Rabi season of 2008-09 and 2009-10. Total 18 treatment included residual effect of 3 different doses of inorganic fertilizers and 3 different manures (FYM, Vermi-compost and Cow Pat Pit) and direct 3 doses of inorganic fertilizers to wheat crop were tested. The yield attributing characters of wheat like Spike length (cm), No. of spikes m-1, No. of spikes plant-1, No. of spikelet spike-1. No. of seed spike-1, Seed weight g spike-1, Seed weight g 1000-1had been found significantly higher with application of 100% NPK to wheat + residual effect of 50% NPK and FYM @ 10 tha-1during two years. Seed yield (4.94 and 4.95 tha-1), straw yield (4.95 and 5.04 tha-1) and harvest index (49.95 and 49.54 %) of wheat were also obtained highest with same treatment combination during 2008-09 and 2009-10. The NPK uptake by wheat crop was also found maximum (119.0 and 123.3 kg ha-1 N, 20.3 and 20.0 kg ha-1 P, 82.0 and 83.6 kg ha-1 K) with this treatment. Similarly, residual impact of 50% NPK and FYM @ 10 tha-1and 100 recommended dose of fertilizers to wheat also obtained significantly higher values of Gross return (Rs.54372 and 62083 ha-1), Net return (Rs. 42479 and 48213 ha-1) and B:C ratio (4.57 and 4.48) during both years.
