The study aims to analyze and estimate the impact of the liberalization of the exchange rate on the corn crop during the period (2000-2019), and the results showed that the cultivated area increased by an annual amount of 30,475 thousand feddans, and it was also found that the farm price, total revenue, total costs, and net return  It increased by 0.083, 0.089, 0.105, and 0.056 pounds/feddan, respectively, while it was found that human labor, automated service, seed price, municipal fertilizer, chemical fertilizer, pesticide price, and rent increased by an annual rate of 0.120,  0.101, 0.088, 0.088, 0.091, 0.106, 0.097 pounds / feddan, respectively, and by studying the impact of the exchange rate on the economic indicators of corn, it was found that it had increased from the first period (2013/2015) to the second period (2017/2019) at a rate of change of 43.02%  , 86.83%, 46.58%, -16.76%, 73.78%, 88.6%, 72.43%, 52.25%, 79.27%, 136.4%, 72.02% for each of the farm price, total revenue, total costs, and net return, human labor, automated service  The price of seeds, municipal fertilizer, chemical fertilizer, pesticide price, rent, respectively, and a study (the effect of passing) during the period (2000-2009-2010-2019) It was found that the rise in the exchange rate of the US dollar against the Egyptian pound by one pound led to a rise in the import price of the total corn crop about 4.32 pounds, and the results of estimating the exchange rate model on the import price showed a positive relationship, as it was found that the increase in the exchange rate  By 10% leads to an increase in the import price of corn by 3.6%, as it was found that there is no causal relationship between the exchange rate and the import price of corn.
