That is why studies of the unification processes of selected features occurring within the countries of this convergence club are taken up. The aim of the paper is to find out whether between EU Member States unification of the agrarian structure occurs. Author assume that the similarity of resources and the structure of the agricultural land may be determinants of this phenomenon.
