This study was conducted to estimates the Malmquist productivity indices using the data envelopment analysis (DEA) for 165 countries over 8 regions and classified across 8 groups based on agricultural gross production value during the study period (1980-2007). The total factor productivity including and measure the efforts in the resource allocation, modernization, the technological change, and catch-up efforts in the agriculture sector in any country. While, Malmquist TFP index measures total factor productivity change between two data points by calculating the ratio of the distance function of each data point relative to a common technology. The data used in this study was drawn from the Food and Agriculture Organization of the United Nations. This paper also estimated the technical efficiency, technical efficiency change and technical change for countries in each group and for all those countries as one group.

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.
