  Background and Purpose:The aim of this study is to provide cropping pattern with different objectives to maximize the private and social benefits is separately in the city of Marvdasht. To determine the optimal cropping pattern mathematical programming models was used. Methods: This study was collected the part of data such as yield, price and cost of production of crops and inputs to produce these products in hectare using two-stage cluster analysis method from 97 questionnaire. Results: The results showed the total cultivation area in this case relative to the total current cultivated area was unchanged. But in this model products such as irrigated wheat, dry land wheat, corn, watermelon, cucumber, onion, beans and irrigated lentils removed from the pattern and irrigated barley, melons and onions (with 33193, 1477 and 43126 ha) were planted into a pattern. Also tomato cultivation increased 93 hectares. Conclusion: The results showed social benefits and gross margin in this model relative to current model increased 1627170000000 and 1482915224150 IR.
