A field experiment was conducted during 2013-14 and 2014-15 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut-250110 (U.P.).The objective of our study was to establish an understanding of how nutrient uptake and wheat yield can be improved and how land configuration and tillage practices can be modified to be more efficient in water use through layering of precision- conservation crop management techniques. The experiment consisting of five tillage practices T1- Wide raised bed; T2- Narrow raised bed; T3- Conventional tillage; T4- Reduced tillage; T5- Zero tillage and three treatments viz., I1 -IW/CPE 0.45; I2 -IW/CPE 0.60; I3 - IW/CPE 0.75;was laid out in split plot design with three replications. The maximum net profit among tillage practices Rs 64301.7 and Rs 60904.3 ha-1 with B: C ratio 2.24 and 2.00 were recorded in wide raised beds plots. The wide raised beds plots increased the water use efficiency of 15.12 and 15.78 kg grain ha-1 mm. The per cent increased in water use efficiency under wide raised beds over conventional tillage was 38.67 and 39.23 %. Among water regime highest net profit (Rs 65256.4 and Rs 61976.7 ha-1) with B: C ratio of 2.24 and 2.04 was recorded with the application of three irrigations at 22, 65 and 105 DAS in wheat crop. The wide raised beds plots increased the water use efficiency of 15.12 and 15.78 kg ha-3 and water productivity (1.28 and 1.18 kg ha-3). The per cent increased in water use efficiency under wide raised beds over conventional tillage was 38.67 and 39.23 % during 2013-14 and 2014-15, respectively.
