Dragonhead (Dracocephalum moldavica L.) is an annual, herbaceous, balm-scented and spicy medicinal plant of Lamiaceae family.An experiment was carried out during successive season to investigate the response dragonhead various sowing densities (10, 15, 20 40 cm) iron nano-fertilizer (0, 1, 2 3 g lit -1 ) applications.Iron a necessary element for plant's growth plants deficiency or deactivation show with chlorosis their leaves.Results ANOVA indicated there not any significant interaction between density.Iron levels had promoting influence on most traits accelerated essential oil accumulation.Similarly, wider spacing greatest effect some components.Generally, third rate (2 combined moderate distance (15 favorable traits.The forth level density (40 best in number flowering branches, secondary branches stem diameter while second yield.Three 1 produced long height first branch two (1 high branches.The - values total anthocyanins, chlorophyll b flavonoid traits.Two magnitudes a, chlorophyll, 270 nm, 300 nm 330 traits.It can be advised that medium ), could used achieving yield performance.
