Sugar beet is an important crop that helps in establishing integrated agricultural-industrial societies, especially in the new reclaimed areas, it contributes in many industries such as sugar industry, and highly-value animal feed resulting from processing waste. Sahl El Tina had been chosen as it is one of the most important of the recent reclamation and aquaculture region depending on water of Al Salam Canal. To achieve the target of increasing Production of sugar beet it became necessary to increase the efficient use of economic resources ,and to achieve this objective study Data Envelopment Analysis (DEA) Approach had been used in order to estimate the technical and economic efficiencies allowing to reduce production costs and increase revenue, and thus support the expansion in the cultivation of the crop. The sample have 3 categories according to the area of the farm, the first category consists of 3 feddans or less, second category is more than 3 feddans and less than 7 feddans, the third category is more than 7 feddans to 10 feddans. The goal of the sample was to compare the efficiency of these categories, and recommended the optimum size of the farm.
