The aim of the paper is to analyze the reasons for the still continuing organizational restructuring and for the transition of Bulgarian agriculture from collective cooperative forms to prevailing sole proprietors and small size collective partnerships based on stake principle. The conclusions and assessments in the paper are based on the data from 2003 Census of agricultural holdings and on results from two research regional projects: "The Land-leasing model of agriculture in Dobrich region" and "Integrated development of rural regions in Haskovo area".
