The diploma thesis focused the economic efficiency of growing oat and spring barley in a conventional and organic farming system during 2018 to 2022. The thesis is divided into two parts, the literary part and the practical part. The literary part describes economic efficiency, agriculture, agricultural subsidies and selected crops. The practical part includes calculating the profitability of crops in both systems. The basic rate of profitability was determined based on the revenues, purchase prices and costs of each business. In the end, financial support in the form of subsidies to which the selected companies are entitled are added to the calculation of profitability. In addition to the calculation itself, the thesis includes the causes of the resulting difference in efficiency between the two systems.
