A field experiment was conducted for two years at the Water Management Research Centre, Belavatagi, Karnataka, India, to find out suitable contingent crops for different late water supply situations. Planting of chilli (Capsicum annuum) with August release of canal water produced significantly highest maize (Zea mays) equivalent yield (143.2 q/ha) which is closely followed by sowing chickpea (Cicer arietinum) (104.1 q/ha) with release of water during October. Hybrid maize sown with August release of water was more water use efficient (10.53 kg/ha mm) followed by chickpea sown with October release of water (10.27 kg/ha mm). Chilli planting with August release of water resulted in significantly higher net returns (Rs.61367/ha) and B:C ratio (4.84) and water productivity (Rs.15.46/m3) followed by sole desi cotton (Gossypium arboreum). Sowing of desi cotton during September resulted in higher yield (22.0 q/ha), net returns (Rs. 31 630/ha) and water productivity (Rs.8.90/M3). Chickpea with canal water release in October-November produced higher yield (31.2 q/ha), net returns (Rs. 48 250/ha) and water productivity (Rs.13.44/M3).
