Abstract: Nitrogen fertilizers had significant effects on the dry herb yield, of one-year-old
of Agastache foeniculum plant. The results of hydro distillation of the dry herb of A. foeniculum in
the Clevenger-type apparatus showed the following results: The highest essential oil content
(2.88 %) was extracted from the herb of plants which received 100 kg/ha nitrogen and the lowest
essential oil content (2.1 and 2.3 %) isolated from the herbs that received 50 kg/ha nitrogen and
control treatment (0 kg/ha nitrogen) respectively. According to the GC and GC-MS analyses, it could
be concluded that nitrogen fertilizers significantly affected on the essential oil compositions of
Agastache foeniculum such as camphen, p-cymene, β-pinene and α-guaiene. Amount of methyl
chavicol as the main composition of the essential oil was 95, 94.5, 94.2, 94.5 and 95.5 % from the herb
which received 0, 50, 100, 150 and 200 kg/ha nitrogen fertilizer respectively.
