The research is performed to estimating the technical efficiency for important Egyptian governorates in sugar beet output. In order to fulfill the above objective the research depends on the quantitative analysis for estimating the technical efficiency with using Data Envelopment Analysis (DEA). The research had come to some important results and conclusion can be summarized as follows. 1- With measuring the technical (productivity) efficiency for sugar beet for different governorates, with using (DEA) showed that: (a) It had been achieved for Dakahlia, Sharkia, Fayoum and Assiut governorates, the average for the technical efficiency was about 0.97,this indicates to can increasing it with about 0.03 with using the same economic resources. (b) All of governorates are increasing return of scale except Assiut governorate had fixed return of scale. (c) Founding slacks in using capital was about Garbia governorate, addition to found slacks in using labor was about 133.57, 70.82 and 21.17 for Mania,Kafr-Elsheikh and Beny-souif governorates. 2- The economic implications of achieving the technical efficiency of sugar beet at the Agriculture level., (a) This achieving will increase the sugar beet output equivalent expands of Agriculture land by 0.12, 8.99,2.13 and 2.24 thousand feddan with total was about 13.48 thousand feddan. (b) The governorates respectively as well as achieving saving of irrigation water at 0.0003, 0.0225, 0.0064 and 0.0067 billion cubic meters with total was about 0.036 billion cubic meters respectively. Lastly in light of the results the research can suggest some recommendation such as: (1) Concentrate cultivation of sugar beet in the governorates of high productivity (Assiut and Menia) and increasing the productivity efficiency for governorates had medium and low productivity, (2) Using the modern technology for devolving the sugar been output, (3) Saving and devolving of the production efficiency inputs with optimal quantities and in suitable time.
