Abstract: 

Due to study the effect of sowing dates on Dragonhead, this research trial was carried out on randomized complete block design with three replications. The effects of sowing dates on 6 of March, 19 of March, 4 of April, 20 of April, 5 of May, 21 of May, 5 of June and 21 of June were studied on growth and herb yield of Dragonhead. The results showed that sowing dates has significant effect on growth and development of Dragonhead. The highest plant (82.5 Cm) and the largest number of branches per plant (18.14) was obtained from the plants which were sown on 19 of March and essential oil content (199.0 Kg/ha) was obtained from the plants which were sown on 4 of April. There was no significant effect among herb yield and essential oil percentage of different sowing dates. The highest essential oil content obtained from the plant were sown on 4 of April, therefore, sowing this plant is recommended.
