Irrigation plays a key role in agricultural production. It not only provides water to the plants, which is essential for their growth, but also makes it possible to use other inputs at high level. It is an established fact that lack of adequate and timely supply of Irrigation water acts as binding constraint to rapid growth in agril. production. in most of the new irrigation projects in India, the extent of utilization of irrigation potential leaves much to be desired. Besides this wide gap between the development and utilization of the Irrigation potential, the efficiency in the use of irrigation water is low. Unfortunately till recently attention has been confined to the creation of irrigation potential. Little attention is given to the factors related to quantitative and qualitative aspects of water use on the farm. The irrigation water is often not applied to the field crops at the appropriate time and in optimum quantities to ensure maximum yields. Therefore, the optimum allocation and economic use of a crucial and scare input like irrigation water is a basic problem which needs immediate attention. Hence it is necessary to formulate proper policies regarding scheduling of water delivery from canal based on plans under varying resource constraints. In irrigated agriculture, where various crops are competing for limited quantity of water, linear programming is one of the best tool for its optimum allocation. Under such conditions of water scarcity, the farmer would like to adjust the cropping pattern according to its availability in different time periods. Such adjustments are considered in the present study. The study is confined to Jayakwadi project stage I (Maharashtra) which is the biggest project irrigating about 142000 hectares of land in its Ist phase. An attempt has been made in the study to develop optimum cropping pattern for existing and improved level of technology at various situations, to identify crucial periods for irrigation water utilization and to work out its productivity, to allocate water optimally among various crops grown in command area, and to estimate the requirement of inputs at existing and improved levels. The results of the study will be useful to the administrators, planners and farmers in the command area for increasing the agricultural production.
