Abstract: The field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during Rabi season of 2014-15 and 2015-16. Comprised whitsixteen treatments combination formed Viz; four moisture regime, and four nutrient management which were allocated in split plot design with three replications. The four moisture regime I₁; 0.6 IW/CPE ratio I₂; 0.8 IW/CPE ratio I₃; 1.0 IW/CPE ratio and I₄; 1.2 IW/CPE ratio were as main plot and four nutrient management 100% RDF through inorganic fertilizers (120:60:40 kg NPK ha^-1), 75% NPK+ 25% N through FYM (90:45:30 kg NPK ha^-1). 50% NPK+ 50% N through FYM (60:30:20 kg NPK ha^-1) (d) 25% NPK+75% N through FYM (30:15:10 kg NPK ha^-1) were kept as sub plots. The growth attributes viz; number of shoots, plant height, dry matter accumulation and yield attributing characters viz, number of grains spike^-1, number of spike m², length of spike, test weight, grain and straw yield, harvest index, nutrients uptake by crop was significantly increased 75% RDF (90:45:30 kg NPK/ha +25% N through FYM along withI4; 1.2 IW/CPE ratio moisture regimewhich was at par with 100% RDF(120:60:40 kg NPK/ha)along with I4; 1.2 IW/CPE ratio moisture regimeand significantly higher over rest of the treatment as well as economics of various treatments were recorded. Moisture regime of 1.0 IW/CPE ratio (5-6irrigations) was found suitable for achieving higher yield of wheat with 75% RDF (90:45:30 kg NPK/ha +25% N through FYM followed by 100% RDF (120:60:40 kg NPK/ha) was found suitable higher growth and yield of wheat crop. On the basis of results obtained, application of 75% RDF (90:45:30 kg NPK/ha +25% N through FYM, nutrient supply system and I4; 1.2 IW/CPE ratio moisture regimefound to be more suitable for higher yield of wheat variety Malviya 234
