This paper reports the results of community-based, on-farm irrigation management trials conducted in Tamil Nadu, India. The experiments were conducted during 1992-97 at two different sites of the Cauvery Delta Zone, Rajendram and Vaidyanathanpettai, to determine the requirements and benefits of improved irrigation management. Treatments include: continuous flooding (control) and improved irrigation management (intermittent). The improved irrigation management reduced water use at the head and middle reaches and spared more water for farmers at the tail-end compared with the control. Under the control treatment, an inadequate water supply at the tail-end area led to low rice yields, whereas the improved irrigation management permitted judicious use of water by all farmers and resulted in increased rice yields by 9, 11 and 40% at the head, middle and tail-end area. These results indicate that farmers in an irrigation system could increase rice productivity through the judicious management of irrigation water and equal sharing of water from the head to the tail-end area.
