Effect of Integrated Nutrient Management (INM) on Yield and Economics of Wheat

A field experiment was conducted at Research Farm of A. S (P.G) College, Lakhaoti, Bulandshahar (U.P) during rabi season of 2004 – 05 and 2005 – 06 to find out the effect of integrated nutrient management on productivity and economics of wheat (Triticum aestivum). Conjuctive use of Vermicompost, Phosphate solubilizing bacteria (PSB) and Zinc in collaboration with 100% recommended fertilizer dose produced significantly higher grain and straw yield of wheat as compared to its counterpart of 50% NPK, whether applied alone or in combination with FYM, PSB, Zn and Vermicompost. The yield attributes like earhead length (cm), number of grains per earhead and 1000-grain weight (grams) increased by increasing fertility levels from 50% to 100%. In economic consideration, it was found that integration of FYM/ Vermicompost, Zn and PSB with 100% recommended NPK gave higher net income per hectare (Rs 32294) and B:C ratio (2.00) as compared to 50% Recommended NPK.
