A field experiment with three sowing dates (D1-November 5th, D2-November 15th and D3-November 25th) in the main plot and ten treatments in sub plots (control (flat planting (FP) with 100 per cent irrigation (I1)) along with combination of three bed widths (37.5 (BP1), 75 (BP2) and 112.5 cm (BP3)) and three irrigation levels (80 (I2), 60 (I3) and 40 (I4) per cent of I1) was conducted during the rabi 2019-20 and 2020-21 in split plot design with three replications. During both seasons, D1 recorded significantly higher plant height, leaf area index, dry matter accumulation, grain yield, straw yield and water productivity of wheat compared to D2 and D3. Wheat evapotranspiration (ET) of was at par in D1 and D2 but significantly higher than D3. Evapotranspiration was at par in FPI1, BP1I2, BP2I2 and BP3I2 but significantly higher than BP1I3, BP1I4, BP2I3, BP2I4, BP3I3 and BP3I4. Plant growth parameters, grain and straw yield was at par in FPI1, BP2I2 and BP1I2 but significantly higher than BP3I3 indicating 20 per cent water saving. At all irrigation levels, BP2 showed maximum yield followed by BP1 and BP3. Crop water productivity was at par in BP2I2, FPI1, BP1I2 and BP3I2 but significantly higher than BP1I4, BP2I4 and BP3I4. Harvest index was significantly higher in early sowing and in deficit irrigation regimes.
