Effect of sulphur nutrient and moisture regimes on economics of wheat (Triticum aestivum L.) varieties

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.
