The present investigation was conducted in wheat at the Punjab Agricultural University, Ludhiana, to study effect of four tillage viz mould board ploughing to a depth of 25 cm followed by rotavator (PT25+R), mould board ploughing to a depth of 14 cm followed by rotavator (PT14+R), zero tillage with happy seeder (ZT) and conventional practices (CT) and three irrigation scheduling based on IW/PAN-E ratio I1 ( 0.6 ), I2 (0.8) and I3 (1.0) on soil water balance and crop growth for two consecutive years (2016-17 and 2017-18). Straw and grain yield was significantly higher in I3 over I1 and I2 by 46.05 & 38.5% and 8.72% & 11.30 % respectively during both years. Water productivity increased significantly in I2 over I1 and I3 by 27.38 & 2.26% in 2016-17 and 27.70 & 1.91% in 2017-18. During both years higher water was stored by ZT & I3 over PT25+R, PT14+R, CT, I1 and I2. During both years highest water was depleted under PT14+R & I1 over PT25+R, ZT, CT, I2 and I3. The overall mean number of tillers, leaf area index, root length and mass density were significantly higher under PT25+R than PT14+R, ZT and CT.
