Summary:

The main aim of the research was to present comparative analysis of organization, productivity and profitability of conventional and organic dairy farms. The research was based on statistical data in form of time series from Farm Accountancy Data Network (FADN). The study have proved that productivity and profitability of organic farms were significantly lower than in case of conventional farms. Such trend results mainly from two factors: business volume measured by farmland areas and size of stock and apparently lower milk cows yield.
