The crop water requirements for the major Rabi crops viz. wheat, barley and gram were computed by Penman-Monteith method using computer program ¿CROPWAT¿. Distributary wise water supply and water demand was estimated for water balance analysis. The performance was evaluated using the adequacy and relative water supply indicators. These indicators were calculated for the ten distributaries for the 5-month irrigation period of Rabi season. Data ware collected from field and irrigation department. The analysis of results indicated inadequate and inequitable canal supply mainly at tail distributaries of both LMC and RMC. A linear programming irrigation planning model was developed considering three specific objectives viz. production maximization, net benefit maximization and labour employment maximization and is experimented for various levels of surface water availabilities i.e. no of canal running days in a season (70,80,90,100,110 & 120days). The model is also implemented for conjunctive use of surface water and ground water.
