In most of the canal irrigation project in Uttar Pradesh, India, water supply is highly varying and insufficient to irrigate the command area throughout the crop-growing season for which it was planned and constructed. The paper presents a case study to investigate the main causes of such problems and to find suitable solution for sustainable crop production. The study was carried out during 2005-2006 for Kareha, Hindupur, Barha, Bendo, Pandeora, Bhitar, Amlo, Purwa and Deha of Karchana distributary (Tons main canal) of state of Uttar Pradesh. Intensive survey revealed a controversy between water users and canal authorities. Water users complain that the water supply by canal is inadequate, whereas authorities claim that they supply sufficient amount of water to meet the irrigation demand. Gathered information were analyzed using FAO guidelines. Potential evapotranspiration was computed by modified penman model. Crop water requirements, irrigation requirements, leaching requirements and project supply requirements computed. Deficient and excess water supply periods were identified. Results revealed that water supplied by the Kareha, Hindupur, Barha, Bendo, Pandeora, Amlo, Purwa and Deha of Karchana distributary were highly insufficient to meet the supply requirements for their respective command area but water supply by Bhitar was very much in excess to meet the supply requirements for its command area. The overall efficiency of canal irrigation project in India is approximately 35-40% mainly due to poor repair and maintenance, damaged sluice gate, weed growth, silting and lack of farmers training and participation etc. The paper finally discusses the feasibility of participatory irrigation management in order to find the solution for such problems. The results revealed that participatory irrigation management should be adopted in order to improve the overall performance of Karchana distributary (Karchana block) for higher crop production as well as economic conditions of farmers.
