Adamisin P., Kotulic R., Kravcakova Vozarova I. (2017): Legal form of agricultural entities as a factor in ensuring the sustainability of the economic performance of agriculture. Agric. Econ. -Czech, 63: 80-92.Abstract: Development of the agricultural sector prior to 1989 in Slovakia, such as in most countries of the Central and Eastern Europe, was aff ected by the collectivization realized on the principle of the central planning. Th e main objective became the quantity, while quality and effi ciency had only a secondary importance. Entering into a new market environment after 1990 meant for agricultural enterprises complicated structural, economic and social changes. Th e aim of the paper is to evaluate the economic performance of agricultural entities depending on their legal form in Slovakia. We assume that the legal form or the way of organizing and management of processes within the agricultural enterprises has an impact on the economic performance of the agricultural subjects. Th e analysis confi rmed the assumptions. On the basis of the testing results, it was found that business companies show a higher rate of economic success measured by the selected economic indicators.
