On farm demonstrations were conducted during kharif seasons of 2013 to 2015 at farmer’s field in Chambal command area of Rajasthan under Operational Research Programme of Agricultural Research Station, Kota to study the impact of improved water management technology on the water productivity and sustainability of rice. Treatments comprised irrigation of 5±2 cm standing water and refilling at 1-3 days after disappearance of ponded water which was compared with the farmers practice (FP) i.e. continuous submergence. Results revealed that improved water management technology gave higher and sustainable yield of rice over the years. The mean grain yield (4,531 kg/ha), production efficiency (34.8 kg/ha/day) and crop monetary efficiency (Rs.728 /ha/day) recorded under IWMT being 7.0, 7.1 and 7.8 per cent higher as compared to the farmers practice, respectively. Mean sustainability yield index (0.913) and sustainability value index (0.888) were found 2.87 and 4.0 percent higher under IWMT in comparison to FP, respectively. Mean water expanse efficiency (92.9 kg/ha-cm), water use efficiency (35.2 kg/ha-cm), water profitability (7.35 Rs./M3) and incremental cost benefit ratio (4.8) observed were also better in IWMP than farmers practice.
