Tomato is one of the most important vegetable crops, and North Sinai is one of the leading Governorate in the production of the tomato crop under system of plastic domes, The area planted for the tomato crop under this system amounted to about 1091 Faddan, contributing to the production of about 19.01 thousand ton, with an estimated monetary value of about 57.3 million L.E, during the year 2019. The problem of the study is the fluctuation of Faddan productivity from year to year, and from one loop to another, and from one region to another within the governorate. It is a rapidly perishable crop, and it needs appropriate environmental conditions, high prices of production requirements, and the study aims to identify the productive and economic efficiency of tomato production farms under the dome system. In achieving its objectives, the study relied on the method of descriptive and quantitative economic analysis of the study variables, and on the initial data of a random sample of about 120 producers of tomato crop farmers under the system of plastic domes. 17.53 ton, and the obtained production function estimates indicate that there is a positive, statistically confirmed relationship between the amount of production under the system of plastic domes and each of the amount of municipal fertilizer, the amount of chemical fertilizer, the size of human labor, and finally the amount of fungicides and insecticides, this has reached the general average return of the L.E The investor reached about 54.28% at the level of the total sample farms during the 2020 season. The general average of economic efficiency was about 0.71. This indicates that the L.E spent on fixed and variable production factors achieves an added value of 0.71 L.E the study recommends the need to pay attention to the tomato crop by importing new varieties characterized by high productivity and quality, with attention to the issue of production for export, in the presence of an effective role for the agricultural extension system.
