The highest maize cob yield was observed under permanent broad-bed furrow irrigation with residue (PBBF+R, 11.48 t/ha) and the lowest in conventional till flatbed furrow irrigation (CTFBF, 9.79 t/ha). The highest cob yield and lowest water use resulted in the highest water productivity (20.15 kg/ha-mm) in PBBF+R, which was 17% higher than that in CTFBF. During Rabi season, the sunflower seed yield was the highest under ZTSDI+R (2.16 t/ha). The seed yield of ZTSDI+R was statistically at par with zero-till sub-surface drip irrigation (ZTSDI), zero tillage drip irrigation with residue (ZTDI+R) and zero tillage drip irrigation (ZTDI). The seed yield was the lowest in CTFBF (1.51 t/ha). The highest seed yield and the lowest water use under the ZTSDI+R led to the highest water productivity (7.07 kg/ha-mm).
