Subsidies are one of the most used means of support given to the entrepreneurs (natural persons) running agricultural production. The main goal of this research was to determine a share of subsidies in the entrepreneurial success of self-employed farmers farming in adverse natural conditions. The results were achieved by the use of the method of regressional analysis, F-test, t-test, as well as a percent share of subsidies in total incomes. Results were compared with those of the Slovak Ministry of Land Management concerning the Slovak Republic as a whole.
