To grow the sugar beet crop in the new lands is of great importance in closing the sugar gap in Egypt, so the research aims to study the factors affecting the production of sugar beet crop in the new lands in Assiut Governorate, the highest productive province of the crop in the new lands in 2017, and to achieve this goal the research relied on the use Data envelopment analysis (DEA) in accordance with the concept of fixed return of capacity and variable return of capacity to estimate the Technical Efficiency- Allocation Efficiency- Economic Efficiency. of the sugar crop in the sample of 92 farms collected randomly, he results indicated that the technical efficiency of the study sample assuming the fixed return of capacity averaged 97.4% and the number of farms achieved for optimum technical efficiency 39 farms or about 42.39% of the total farms of the sample research, while the average technical efficiency assuming variable return of capacity was 99.5% and the number of farms achieved for optimum technical efficiency was 83 farms or about 90.22% of the total farms of the research sample, The results also indicated that the Allocation al-Sample farms' Allocation efficiency by assuming a fixed return on capacity averaged 78.3%, i.e. the redistribution of the economic resources used will provide 21.7% of the resources used for the 91 farms that did not reach optimal Allocation efficiency, representing about 98.91% of the total research sample farms, in addition to the economic efficiency averaged 76.3%. That is, the same level of production can be achieved at a cost 23.7% below the actual cost for the 91 farms that did not reach optimal economic efficiency, representing about 98.91% of the total research sample farms, and when estimating the Allocation efficiency of al Ain farms. Assuming a variable capacity return, it averaged 80.4%, which means that the redistribution of the economic resources used will save 19.6% of the resources used for farms that did not reach optimum Allocation efficiency, which represents about 98.91% of the total. Of the total research sample farms. The average economic efficiency was 80.1%, which means that the same level of production can be achieved at a cost 19.9% below the actual cost for the 91 farms that did not reach optimal economic efficiency, representing about 98.91% of the total. To the farms sample research, the research recommends activating and activating the role of guidance in encouraging farmers to start planting sugar beets, and educating farmers about the optimal fertilizer decisions so that they do not overuse them, in addition to increasing the incentive in farmers to determine the appropriate prices for the supply of sugar beet crop for factories, as well as providing production supplies at affordable and timely prices.
