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 2013-14 and 2014-15.The experiment was carried out in split plot design with three replications. with 24 treatment combinations, comprised of four irrigation levels (a) I₁; 0.6 IW/CPE ratio (b) I₂; 0.8 IW/CPE ratio (c) I₃; 1.0 IW/CPE ratio and (c) I₄; 1.2 IW/CPE ratio with two varieties namely PBW 343 and PBW 502 and three sulphur levels (a) Control (b) 20 kg/ha (c) 40 kg/ha. The growth attributes plant hight, no of shoot m² and leaf area index was significantly superior 1.2 IW/CPE ratio with PBW 502 variety at all growth stages except 30 days after sowing. PBW-502 (V2) wheat cultivar recorded significantly higher yield of crop over PBW-343 (V1). Moisture regime 1.0 IW/CPE (I3) has been found most suitable for wheat production. The optimum dose of sulphur has been found as 20kg/ha (S2) for wheat production. Wheat cultivar, PBW-502 (V2) recorded the significantly high uptake of NPK and sulphur under 1.0 IW/CPE moisture regime (I3) with 20kg/sulphur dose kg/ha. (S2). Wheat cultivar PBW-502 (V2) accrued the maximum net return with B:C ratio of 2.65 and 2.47 under 1.0 IW/CPE moisture regime (I3) with 20kg/ ha. Sulphur dose (S2) during the year 2013-14 and 2014-15, respectively.
