Abstract
The study aimed to measure Economic Efficiency and its components, Technical Efficiency and Allocative Efficiency on the input side, and to impose a change in returns to scale VRS by using the DEA method of data envelope analysis, as well as to review the structure and items of costs for tomato production, and knowing The extent to which economic units achieve a rational use of production resources. the data necessary to study in the field were collected through a questionnaire carried out in a personal interview of (124) farmers of the tomato crop in the open cultivation method in Nineveh Governorate (Zammar district as an application model) for the production season 2019, Included explanatory variables (seeds, fertilizers, pesticides, mechanical work, human work) As for The approved variable is tomato crop production, and the study reached many conclusions, the most important, That three farms (2.4%) achieved complete technical, allocation , economic efficiency (100%), and the results of showed that the average economic efficiency reached about (50.8%), meaning that these farms can achieve the same level Of production in light of reducing production costs by 49.2%, and the study recommended that farmers use resources Economic needs according to the crop’s need for these resources and in a way that minimizes costs and maximizes profit, and it is necessary to study the reasons for the success of many farms that have achieved complete Economic Efficiency (100 %), To be references to farms that have not achieved Economic Efficiency Although it in the same circumstances.
