Efficiency of economic results in rapeseed production is formed by many components, which can be grouped according to several features depending on the research aim, hypothesis and tasks. Economic aspects of rapeseed production are significantly influenced by productivity dynamics of oilseed rape sowings, changes in productivity levels, regional aspects of cultivation conditions, size of farms, and specialisation and concentration of production. Three methods were used in the research: dynamic time-row analysis method to estimate crop productivity and growth of other parameters in a longer period of time, grouping method to investigate the influence of production concentration, and logical construction method. It is recognised that large agricultural holdings are the most important rapeseed producers. Three fourths of the total rapeseed areas are concentrated in these enterprises accounting for 82% of the total yield produced by all rapeseed-production farms together. One fifth of the total area under oilseed rape belong to medium-sized farms; however the proportion of the total rapeseed yield obtained in this group of farms is by one third lower than that produced by large agricultural holdings. Insignificant number of small-scale farms is engaged in oilseed rape cultivation. Significant differences observed in rapeseed productivity levels among particular regions except natural (soil, climatic, etc.) factors are greatly affected by the applied amount of fertilisers and crop protection products. In meteorologically unfavourable years, yield decline in farms high in seed yields is considerably lower compared with lower productivity farms.
