Тhe study focus on the Total Factor Productivity (TFP) for selected agricultural sectors (fruit growing, viticulture and dairy cattle breeding). The methodology used to determine TFP is according to Regulation (EU) 834/2014 laying down monitoring and evaluation framework for CAP 2014-2020. The Laspeyers index was applied to analyze the development of agricultural production and to explore the influence of different factors on the production output during the CAP implementation. The change was reviewed in comparison to a basis period and TFP was estimated as an index coefficient represented as industry output and the driving inputs (including labour, capital, land, variable production costs and subsidies).The study reveals a significant change in TFP indexes over the period after Bulgaria's accession to the EU. The results show the TFP indexes decrease for fruits and cow's milk and increase for grapes (due to improved efficiency). There is a drop in production for grapes and cow's milk but a significant increase in production quantities for fruits. Meanwhile, the TFP index for fruit growing is slumping down, which is explicated by tangible enhancement in investment and capital costs during the covered period, which deems to improve the productivity and efficiency in the coming years. There is a need to increase and target the financial support for viticulture and dairy farming in order to hoist up the productivity and production outputs.
