Abstract: 

In this study, economic and environmental targets, optimum cropping patterns were determined by using Lexicographic Goal Programming (LGP). Results showed that farmers, decision making will be facilitated under adverse environmental condition by using the model and it is possible to determine preferred confidence level for any constraints of the model easily. In environmental structure, cultivated area decreased, sugar beet had maximum cultivated area and onion eliminated from cropping pattern related to current condition in economic structure, corn had maximum cultivated area. In linear programming model, total cultivated area decreased, wheat had maximum cultivated area and sugar beet eliminated from cropping pattern.
Furthermore, in comparison with existing condition, the amount of water and fertilizer consumption in economic structure decreased and consumption of water, fertilizer and machinery showed decreasing in environmental structure related to economic structure and current conditions. On the basis of findings, by considering environmental targets, there is also a possibility for increasing profit and productivity of inputs related to current condition.
