A field experiment was conducted during winter season of 2006–07 at agronomy research farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad. The experiment consisting of eight (8) treatments viz T1 (100% recommended dose of fertilizer through inorganic sources), T2 (50% recommended dose of fertilizer through inorganic sources + 50% N through FYM), T3 (75% recommended dose of fertilizer through inorganic sources + 25% N through FYM), T4 (50% recommended dose of fertilizer through inorganic sources + 50% N through vermicompost), T5 (75% recommended dose of fertilizer through inorganic sources + 25% N through vermicompost), T6(100% N through FYM), T7(100% N through vermicompost) and T8(control) was laid out in randomized block design with four replications. Growth parameters such as plant height, number of shoots per meter row length, total dry matter accumulation per meter row length, leaf area index (LAI) and crop growth rate (CGR) were significantly higher in recommended dose of fertilizer through inorganic sources which was at par with 75 per cent recommended dose of fertilizer through inorganic sources + 25% N through vermicompost and 75 per cent recommended dose of fertilizer through inorganic sources + 25 per cent N through FYM over other treatments. Yield attributes viz spike length and number of grains per spike increased significantly with recommended dose of fertilizer through inorganic sources which was at par with T3 and T5. Grain, straw and biological yield were highest with recommended dose of fertilizer through inorganic sources which was at par with T3 and T6. 75 per cent recommended dose of fertilizer through inorganic sources + 25 per cent N through vermicompost improved available N, P and K content in soil compared to other treatments. Protein content was maximum with T1. Highest gross return was observed with recommended dose of fertilizer through inorganic sources followed by 75 per cent recommended dose of fertilizer through inorganic sources + 25 per cent N through FYM.
