Özet

Dragonhead (Dracocephalum moldavica L.) is an annual herbaceous, sometimes biennial, which is aromatic, and belongs to the mint family (Lamiaceae). In order to investigate the effect of sowing date, plant density and harvest time on essential oil compounds of dragon head, a split-split plot experiment was done as base of randomized complete blocks design with three replications in turkey at spring and summer of 2018. Sowing date in three levels (5 May, 15 May, 25 May) as main plot, distance on row in three levels (15, 30, 45 cm) as sub-plot and harvest time in three levels (50% flowering, 100% flowering, seeding tame) as sub-sub plot were considered. Results of the analysis of variance revealed that Z-Citral (Neral), Geraniol, E-Citral (Geranial) and Geraniol, belonged to the oxygenated monoterpenes group, were the major compounds of dragon head essential oil. The data mean comparison indicated that Geraniol, as the main compound of essential oil, had the highest amount in first sowing date (5 may), 45 cm distance on row and seeding harvest time with mean of 40.21%.
