Cucumber is found amongst vegetables grown for 3000 years and is of particular importance because of its nutritional value with a very low caloric intake. Cultivation of cucumbers is one of the most widespread in our country and can be consumed in both crudest and preserved state. In the present paper, based on some technical and economic indicators, an estimation of the economic efficiency for the cultivation of cucumbers cultivated in protected areas for conventional and ecological agriculture was made. Economic efficiency has been estimated in terms of applying modern technology to the production process and the rational use of material, human, financial resources to provide superior products at a low cost. Actions taken on agricultural holdings are permanently guided by the economic efficiency of crops.
