The main purpose of this paper was to identify the determinants of farm revenues in the EU-15 countries. The study was based on FADN regional data for 2011-2013. Factor analysis was used to address the above issue. Based on this study, it may be concluded that the key determinants of farming revenues in the EU-15 countries are as follows: size of the farm (measured both with the production potential and with the production value), operating subsidies, production intensity and plant production yields.
