Abstract<\/strong><\/p>\n

This research was carried out in Aleppo Governorate (Deir Hafer region), and preliminary data was collected from a sample of cotton farmers for the 2019 agricultural season to estimate the functions of demand for chemical fertilizers during the season. Through the studied sample, it became clear that most farmers used two types of chemical fertilizers, namely urea and triple superphosphate, the mainstay of this research It is the estimation of the cotton crop production function, and the best mathematical formula that was reached was the Cobb-Douglas function, and from this function both the cost functions and the fertilizer demand functions were derived. Through the results, the elasticities of the two fertilizers, urea and superphosphate, were reached, which amounted to (0.47,0.19), respectively. The results of the research also showed that if the fertilizer prices were doubled, the demand function for fertilizers would remain the same without any change. As a result, after estimating the expansion corridor equation, the optimal economic combination of nitrogen and phosphate fertilizers was reached and it was (450,280) kg\/ ha, respectively.<\/p>\n

Keywords<\/strong>: Douglas Cup production function, cotton crop, expansion corridor. Deir Hafer region<\/p>\n
