The cost-effectiveness of production is a notion describing the economic efficiency of the activity of each farm. Cost-effectiveness is presented as the relationship of the value of production achieved versus costs incurred. This relationship forms a variant of effectiveness measure known as the cost-effectiveness indicator. The value of the cost-effectiveness indicator in agricultural practice depends not only on the results obtained through the work of the farmer him- or herself, but also on a series of objective conditions influencing production value. Analysis of cost-effectiveness indicators for cultivation forming the basis of production on purposely selected organic farms, both certified and in the course of conversion, is performed in the article. The research encompassed 26 small and medium-sized farms in the świętokrzyskie region specialising in horticultural and permanent cultivations in the economic year 2006.
