Because of this matter, agriculture sector need plants that are adjust to climate of Iran and have a lot of oil, that canola is the best one. In this study, capability of substitution oilseeds in cropping pattern was considered; optimum cultivated pattern of important crops that have most cultivated area of canola in Khorasan Province is considered. Linear programming and risk programming models such as MOTAD and quadratic programming were compared. Models suggest increasing the cultivated area of oilseeds crop. Increasing the cultivated area of canola cause to the pattern cultivating of farmers improve and inputs will used in better way, too.Increasing the cultivated area, it is a movement toward self sufficient in oil seed production that will accompany with noticeable thrift in foreign exchange.
