Koszty ekonomiczne wybranych działalności produkcji roślinnej w latach 2005-2009

The subject of the studies was the diversity of the economic costs and income on management for the five crop production activities, namely: winter wheat, winter rye, winter rape, sugar beets and potatoes for human consumption. The surveys were conducted between the years 2005 and 2009 on the same sample of farms. It should be emphasised, however, that the results presented do not depict the situation of all such holdings in Poland, but only of those which provided farm accountancy data. Empirical data were collected and processed according to the rules of the AGROKOSZTY and Polish FADN systems. The results show that the highest economic costs (calculated per 1 ha), were involved in the cultivation of potatoes and then sugar beet, oilseed rape, winter wheat and the lowest – in the cultivation of rye. All crop production activities allowed to obtain income from management, but in the case of sugar beet in the period 2008-2009 and rye in the year 2009 was carried out exclusively thanks to subsidies, without this support a very distinct financial loss would appear. As a factor influencing income, subsidies play a prominent role. Thereby farmers got return for involvement in the production process of their knowledge, experience or taking innovative measures to achieve the best economic results.
