Improvements in the management of furrow and border irrigation are capable of increasing the water use efficiency (WUE) and yield of crops. Field experiments were conducted during 1999-2000 and 2000-01 to study the effect of improved irrigation management on yield and WUE of cotton and wheat crops in the Indo-Dutch Network Operational Research Project site at Devapur (J) village in Shorapur taluk, Gulburga district in Upper Krishna Project command area, Karnataka (India) by the University of Agricultural Sciences, Dharwad. The study revealed that 49.20% water saving and 27.21% higher cotton yield in the case of improved irrigation method (alternatively alternate furrow irrigation with 0.20% slope) in comparison with the local method of irrigation (all furrow irrigation and 1.45% slope). The WUE of cotton crop varied from 18.14 to 38.08 kg/ha cm in the local method of irrigation and improved irrigation method, respectively. Similarly, the water saving in wheat was 34.74% and the yield increase was 33.17% in the improved irrigation method (borderstrip irrigation method and stream cutoff at 80% length of the border with 0.20% slope) over the local method of irrigation (flooding and 1.18% slope). The WUE of wheat was 42.92 kg/ha cm in the improved irrigation method whereas it was 21.23 kg/ha cm in the local method of irrigation. The cost of land levelling per ha using a 45 hp tractor was Rs. 5320/- for 1.45% slope and it was Rs. 3780/- for 1.18% slope to bring to the permissible 0.20% slope.
