The agricultural sector plays an essential role in the national economy of each country. Today, methods used to determine the pattern of crop rotation with crop risk are often used to increase farmers' well-being and maximize their profits. In the present study, the aim of developing an optimal model of cultivating agricultural crops in risk conditions in Sistan province, Sistan and Baluchestan province, is based on the cross sectional data of 2016-2017 years. For this purpose, the integrated model of goal programmin and the Focus-Loos model was developed. The results showed that in the lands of more than 3 hectares, the gross income in Zabol, Zahak and Hirmand regions was 1954567, 1324568 and 1245751 tomans, and Loss in Zabol and Hirmand region, respectively, were 351254 and 253698.45 USD per hectare, respectively And these results indicate that by increasing the area of aquaculture, farms will select production patterns with a few limited products, and the smaller the farm, the greater the variety of cultivated products will be to reduce the income risk. In all sample farms, the gross income earned is higher than the household's needs for basic needs and can make more investment with it. It is suggested that by implementing the policy of integrating small farms in the Sistan region, it will increase the gross income of farmers and also make optimal use of inputs.
