In this study, we assessed the removing effect of chemical fertilizers subsidies on cropping pattern of agronomy in Shahre-Rey County. For this purpose, by simple random sampling method, 105 evaluation forms from Shahre-Rey County farmers between 2010 and 2011 were filled out, and Positive Mathematical Progamming model (PMP) with maximum entropy (ME) was used. According to cultivated area, farmers were divided into four homogenous groups, and the elimination effect of the chemical fertilizer subsidies through price changes in nitrate, potassium, and phosphate fertilizers was evaluated. The results indicated that the extent of planted areas in all crops was decreased in the first and second groups. In the third group, only the extent of planted areas of wheat and cauliflower was increased about 8.569% and 6.52%, respectively. Finally, in the fourth group, the extent of planted areas of barley was increased about 0.818%. Also, the rate of using inputs was decreased and the planned output of all groups (1, 2, 3 and 4) was declined 4.825%, 5.402%, 8.928%, and 1.512%, respectively.
