The report is a part of the research topic Calculation of gross margins for selected agricultural products and classification of agricultural holdings according to EU standards. The aim was to assess the economic results of selected agricultural products. The surveys conducted allowed to show the trends of production costs, income from activity and the degree of remuneration of family labour inputs in the last few years. It was important to examine the differentiation of the results obtained in groups of farms, i.e. the best, the average and the weakest holdings. The determinants of the value of agricultural production and agricultural income were identified, and the relationship between specific costs and total costs as well as between the gross margin and income from activity was analysed.
