This study is a first attempt to clarify major trends and factors of changes in production and productivity in Post-Second World War Bulgarian agriculture. It incorporates an interdisciplinary approach and specifies crucial institutional, economic, organizational, technological etc. factors affecting development of agricultural production and productivity. Firstly, evolution of agricultural production and productivity is analyzed, and effect of labor, land and livestock productivity on different productions assessed. Secondly, evolution and impact of main technological factors (application of chemicals, mechanization, irrigation, introduction of new varieties etc.) are examined. Third, stages in property rights development and restructuring of farms are presented, and their effects on production and productivity evaluated. Forth, paces in modernization of public policy, its key elements (central planning, price and trade regulations, support programs etc.) and implications for agriculture are identified. Fifth, evolution and role of the demands for farm products is assessed. Next, changes in labor quantity and composition, and their impact on agricultural production and productivity are scrutinized. Finally, effects of climate changes and weather extremes on agriculture are underlined
