Response of different wheat varieties under sulphur nutrient and moisture regimes on the nutrient uptake and yield

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 growth attributes plant height, no of shoot m-2 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) and the optimum dose of sulphur 20kg/ha (S2) has been found most suitable for wheat production. yield attributes like highest number of effective tillers m-2, no. of fertile spikelets spike-1, spike length, number of grains/spike and 1000-grain weight were also recorded highest values with sulphur level of 20 kg/ha which was significantly to other than dose of sulphur. 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.
