In addition to detecting problems with an effective irrigation, for the maximization of farmer incomein the basins where agriculture is concentrated in Turkey, it is necessary to optimize the crops in thatbasin by determining the crops that should be grown, the area at which the crops will be grown and how much irrigation water will be applied. In this study plant water consumption and productioncosts and net income of plants were used as basic data in crop pattern optimization studies. The waterconsumption of plants is calculated by Penman Monteith method. The water consumption of the plants was calculated for 10-day periods and the monthly and seasonal water consumption was obtained by taking the totals. IRSIS software was used to obtain irrigation programs for full irrigation (100% water) and deficit irrigations (80%, 60% and 40% water). Irrigation water-yield relationship was obtained by using irrigation water quantities and yield values for each plant. The non-linear programming technique was then used to determine the optimal crop pattern for each basin to provide maximum operating revenue for different water resource capacities. As a result, total irrigation water needs and net incomevalues were obtained for a farm in the size of 10 ha in the basins where the studies were carried out.Information on the use of irrigation policies and irrigation efficiency by public-private and private sector experts and decision-makers on irrigation investment and management issues has been obtained.
