Maize is considered one of the most important cereal crops in Egypt. After adoption of economic reform policy, farmers became responsive to many variables in making their farm decision eSpecialIy in long run. The main research problem is based on the assumption that farmers of maize are positively responsive to the economic incentives. in contrast to that the governmental interventions in price policy, i.e., the procurement prices and quotas system. adversely affected farmer‘s response. The main objective of the study is to test the reliability of the stated asSUmptions, to determine the most variables affecting the acreage response. annual and full time period response for maize farmers. To achieve that objective. distributed lag models have been applied, by using marc neriove model for estimating maize acreage supply response in Egypt, through period (1987-2004). The results of marc nerlove‘s partial adjustment model for maize supply response functions indicated that. there was a positive response to the farm price of peanut, where the full time period that make the farmer reach the complete response reached about 1.28 years. Also there was a positive reSponse to the net revenue of sesame. where the full time period that make the farmer reach the complete response reached about 1.89 years. Also there was a positive response to the production costs per feddan of maize. where the full time period that make the farmer reach the complete response reached about 2.13 years. Finally, there was a positive response to the relative productivity between maize and sesame. where the full time period that make the farmer reach the complete response reached about 2.17 years. The Study recommended effectiveness the role of technical change in increasing the cultivated area of maize. therefore the role of agricultural extension should be emphasized to increase productivity and net return of maize as an incentive to expand maize area.
