Abstract EN

This study aimed to estimate the technical efficiency of the potato crop in the wadi state to know the rationality of farmers in the use of inputs, as the quantitative border-based methodology is used as an analysis of the data envelope that uses linear programming, A sample of 103 farmers were used to grow potatoes from four municipalities with a wide investment in this strategic crop, namely: Hassi Khalifa, Wermas, Trifawi, and Reguiba.

The study reached several conclusions, the most important of which is that potato cultivation in El Oued is not efficient, as there is a large waste of inputs, Where the average technical efficiency to an input oriented Measures for fixed size returns was 0.

74, and the average technical efficiency related to input-Orientated Measures variable size returns was 0.

83, and the average volumetric efficiency was 0.

89.

The study also found that farmers with large areas are more efficient than farmers with small and medium areas, as they are keen to use resources more rationally
