The paper is another part of the series presenting production and economic outcomes of plant and animal production in AGROKOSZTY system. The research in 2012 covered maize for dry grain, edible potatoes, bovine animals for fattening (i.e. beef cattle) and dairy cows on conventional farms, and dairy cows on organic farms. The individual farms covered by the research were purposely selected from a representative sample of farms in the field of observation of Polish FADN. Therefore average results obtained in the researched set of farms are influenced solely by the structure of this set and the results in selected groups of farms. Therefore the results should not be directly translated into average results for the country. The research aimed at showing the benefits resulting from running production activities on a large-scale farm. It was also attempted to assess effectiveness of use of inputs and activity from the angle of fulfilment of the criterion of economic effectiveness. The assessment also covered labour intensity of production and the possibility to pay for the own labour input.
