Determination of optimum culture pattern of agriculture crops in Sistan region

This research studied culture pattern in Sistan region with method of positive mathematics programming. Datawere collected from Agriculture Department of Zabol city in years of 2012-13. Result shows that for under planting surface of crops there isn?t any significant different between amounts observed in basis year and amounts obtained from crops calibration. Also results explain that models calibration has done with high accuracy, so PMP model is capable to producing amount of basis year again, and simulation of producers behavior do on the basis of actual information. Generally can say that results obtained from models calibration with expense function of quadratic programming model is acceptable. Also elasticizes calculated for chemical fertilizers show that in region under study, price inelasticity is calculated as one of main factors in much consumption of inputs. Therefore farmers with due attention to low price and easy accessibility to these inputs consume from these inputs as non conventional.
