The governorate of Kafr El-Sheikh is characterized by the production of varieties of rice is low in the soil. However, productivity is low compared to the average productivity in the Republic. The study aims to identify the efficiency of the use of agricultural economic resources in the production of rice crop in the study area in order to determine the extent of deviation of the actual production situation from the optimal production level and the maximum return. The study was based on estimating the production function of the rice crop using the Douglas Cobb function in the exponential form and estimating the cost function according to the cubic picture.

The results of the estimated production function indicate that the most important explanatory variables affecting the average production of rice crop in the study sample is the automatic work and the amount of seeds in kilograms and the amount of chemical fertilizers as a unit of oil if the increase of these resources with the presence of other agricultural resources increase the average farm production of rice and calculate productivity The marginal value of these resources was found to be about 0.08466 tons, 0.00891 tons, and 0.00892 tons each, respectively.
