This paper is an attempt at filling the cognitive gap in the effect that human capital has on farms competitiveness. Education is the most measurable characteristic of human capital so the purpose of this paper is evaluating the effect of the manager’s level of education on the competiveness of the commercial farms. The surveys were carried out based on accounting data provided by commodity farms participating in the Polish FADN in 2010-2012. The outcomes indicate a competitive advantage of farms run by managers who completed higher education over entities run by farmers without higher education. Surveys also demonstrated a competitive advantage to the extent of land productivity, equipment of land with technical facilities and labour on farms run by managers with higher education in comparison to farms whose managers had no such education.
