THE RESPONSE OF DRACOCEPHALUM MOLDAVICA PLANT TO NITROGEN FERTILISATION AND PLANTING DENSITY

Wider spacing favoured growth parameters of dragonhead plants. More yield and higher volatile oil content was obtained by using nitrogen fertilisation at a dose of 100kg feddan (4200m²). Volatile oil was composed mainly of acyclic oxygenated monoterpenes which made up 93% of the oil. The oil content of the flowers was double that of the leaves.
