Abstract : The effects of zeolite (0, 20, 25 and 30 g/kg of soil) and soil water discharge (50, 60 and 70%) levels on the growth, development and essential oil content of D. moldavica were studied in a pot experiment. The delay in flowering was most pronounced under 0 and 30 g zeolite/kg with 70% soil humidity discharge (160 days). The earliest flowering was obtained with 25 g zeolite/kg and 50% soil humidity discharge (150 days). Zeolite had a significant effect on the number of flowers, but humidity discharge had no marked effect on this parameter. The number of internodes and plant height were not significantly affected by both the treatments. In the absence of zeolite and increasing soil humidity discharge, the essential oil content decreased; a similar trend was observed under a zeolite level of 25 and 30 g/kg and decreasing soil humidity discharge. The highest essential oil content was recorded for 25 g zeolite/kg with 50% humidity discharge, whereas the lowest was registered for 30 g zeolite/kg and 70% humidity discharge.
