Abstract

Preservative qualities of caraway, known from ancient times, have regained importance as 21<sup>st</sup> century food safety issues predominate. Essential oil content and its composition of annual caraway varies significantly when row spacing and nutrient supply are manipulated under experimental conditions. During 2006–2007, Carum carvi var. annua cultivar ‘SZK-1’ was sown in small plots in three replications with two factors in split plot design. The row spacings were 24 cm, 36 cm, and 48 cm, and six nutrient application rates were applied (Control, N0K80, N80K0, N80K80, N80+70K0, N80+70K80). The results show that the percentage of essential oil content is influenced by the row space. Furthermore, our data show that increased potassium level enhances the amount of d-carvone in the oil. Every treatment of potassium produced higher d-carvone levels (53.34%) than those found in the control. In 2006, the first year of the two-year study, the highest carvone level (66.25%) was measured in the treatment of N80+70K80, whereas in 2007 the highest level occurred in the N80K80 (49.216%) treatment.
