Abstract
The competitive ability of agricultural farms depends on the efficiency of the utilization of production factors. The elaboration presents the differentiation of the production factors use in agricultural farms located in four regions within the framework of the FADN system. The period of farm investigation covers the years 2004-2006. The research deals with the accepted agricultural types of farms: field crops, milk and granivores. A relatively large differentiation of agricultural farms was observed between regions in respect of cropland area, economic size and current financial liquidity. The share of the debts in farms was not significant and remained at a relatively similar level in the regions analysed. The greatest differentiation between the regions concerned the yield of equity. Farms of "granivores" agricultural type, especially those situated in the Pomorze and Mazury regions, were characterized by the highest efficiency of the use of production factors and also by the economic power. The lowest efficiency of these factors appeared in arable farms.
