Improving on-farm water management to increase water use efficiency in farming is relevant, especially when water availability for agriculture is decreasing. This paper attempts to analyze the results of a study on channel to field method of water distribution for rice, in comparison with the field to field method conducted in the command area of an irrigation project in Kerala State of India. The results reveal that channel to field method can achieve considerable water saving and increase in water use efficiency for rice, maintaining a yield comparable to farmer's traditional practice of field to field irrigation However, there exist constraints in its adoption such as cost involved, non-conviction about the method among farmers, problem of excess water availability, absence of group approach in rice cultivation etc. Preference analysis has shown that unless fully subsidized, farmers are not ready to adopt concrete channel to field method of water distribution, even though they have a favourable attitude towards earthen channel method even under lower levels of subsidy. The importance of creating awareness about improved water management methods among farmers, lining of irrigation canals to prevent excess water availability, providing subsidy to farmers and implementing irrigation management transfer to farmers through PIM, thereby promoting a group approach in farming are some of the factors highlighted in the paper for motivating farmers to adopt improved on-farm water management practices.
