The work deals with the possibility of improvement of qualitative and quantitative parameters of caraway (Carum carvi L.). The yield of the achenes is not satisfactory during last years and qualitative demands are clarify in correspondence to the market. The possibilities of this variation can be found in growing technology and in variety spectrum. The influence of weather is inconsiderable. Therefore, the experiments with three varieties were found (PROCHAN, KEPRON and REKORD). They were cultivated in cover crop and as pure growth on three sites. The yield components were evaluated in all variants: the yield of the achenes from m2, HTS (the weight of thousand seeds in g), the essential oil content in % and essential oil yield in kg.ha–1. On the basis of the results from the experiments we can make following conclusions. The highest yield was recorded in Šumperk site with cover crop. The varieties did not affect the yield. HTS was different on the sites, the highest HTS had the achenes from Telč. The differences were determined between vegetative periods. Also the essential oil content, similarly as the HTS, was influenced by the vegetative period and by the site. The essential oil yield corresponded with the essential oil content and with the yield of the achenes. The vegetative period almost always affected yield and the quality of caraway fundamentally. There were no differences among the varieties for all studied traits.
