The aim of this study was to determine optimum cropping pattern and the best selling time of crops. In this study a minimum regret model was applied simulataneously to cross – section data collected from farmers of Ramjerd district in Fars province, and the monthly price of crops of the region in 2001. The availability of previous information about farmers’ risk attitudes was the main reason for selecting this region. The results indicated that cropping pattern with minimum regret is 4.61 ha. of rice, 9.08 ha. of barley and 3.02 ha. of wheat. Also, according to this criterion, the best selling time of crops is recognized to be soon after harvesting.
