Abstract: An experiment was conducted during rabi season of 2017-18 at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, Uttar Pradesh, India, situated at 260.470 North latitude, 80.1200 East longitude at an altitude of about 113.0 meter from mean sea level. Water management on the basis of soil moisture regimes and critical growth stages was used as strategy in this quest to harness water use efficiency, water productivity and yield of wheat crop. The experiment was comprised of eight (8) treatments of moisture regimes viz. (i) 0.8 IW/CPE ratio (ii) 1.0 IW/CPE ratio (iii) 1.2 IW/CPE ratio (iv) two irrigations each at CRI & LJS (v) three irrigations each at CRI, LJS & MKS (vi) four irrigations each at CRI, TRS, LJS, & FRS (vii) five irrigations each at CRI, TRS, LJS, FRS & MKS (viii) six irrigations each at CRI, TRS, LJS, FRS, MKS & DS. The experiment was framed in Randomized Block Design (RBD) with four replications. The wheat variety PBW-502 was used for sowing. The crop was fertilized with recommended dose of NPK and other cultural operations were performed accordingly. The result revealed that irrigations provided in the crop either at soil moisture regimes (IW/CPE ratio) or at critical growth stages of crop did not recognized any significant difference. The treatment provided six irrigations either at 1.0 IW/CPE ratio or at critical growth stages (CRI, TRS, LJS, FRS, MKS & DS) recorded maximum yield potential (45.40 to 46.00 qha-1 grain yield and 65.83 to 66.29 qha-1 straw yield), highly remunerative in terms of net return (net return Rs.65097.0 to 66278.0 ha-1) and B:C ratio (1.85 to1.88). Five irrigation given at CRI, TRS, LJS, FRS & MKS recorded significantly at par.
