Determination of Optimal Crop Pattern for the Irrigation Project Area of Demirdöven

This study was carried out to determine optimal crop pattern in sustainable irrigation project area of 8328 hectare in the demirdöven irrigation project area for the arid, normal and rainy years by taking into consideration seasonal water requirements, irrigation area size, water sources, maximum or minimum cropped area sizes and total and net income per unit area by using a linear programming method. in order to determine optimal crop pattern, qsbwin packed program was used. according to result of this study, the crop pattern resulting in the highest income values were determined as the forage crops of 32,94%, cereal grains of 25%, industrial crops of 25%, cabbage of 2% and vegetable garden of 5,06% for the arid years. these values for the normal year was determined as forage crops of 37,39%, cereal grains of 25%, industrial crops of 25,61%, cabbage of 4% and vegetable garden of 8% and rainy year was determined as forage crops of 43%, cereal grains of 16,59%, industrial crops of 28,41%, cabbage of 4% and vegetable garden of 8% respectively. sustainable plantable area was determined as the level of 90% for arid year.
