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 2003-2004 for Silodhi, Sirher, Khunta, Sinki, Hanokwar, Dhareta, Gulalpur, Pachauna and Dasauti minors of Hardia distributary (Meja branch 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 claims 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 were computed. Deficient and excess water supply periods were identified. Results revealed that water supplied by the Sirher, Khunta, Sinki, Hanokwar, Dhareta, Gulalpur, Pachauna and Dasauti minors were highly insufficient to meet the actual supply requirements for their respective command areas, but water supplied by Silodhi minor was 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 Hardia distributary (Meja block) for higher crop production as well as economic conditions of farmers.
