The experiment was carried out in the split plot based on randomized complete block design with three replications in 2018-2019 growing season. The main plots were consisted of irrigation interval at three level (3, 6 and 9 day) and subplots were consisted of foliar application of Bombardier at four levels (control, 2,4 and 6 ml/L). In the three and six day irrigation interval, the highest and the lowest dry matter yield was obtained in 6ml/L and control treatments respectively. Dry matter yield was decreased by incretion of irrigation interval days. The amount of essential oil decreased, by increasing of irrigation interval. It was identified 29 compounds in the essential oil extracts from plant. The most compounds of essential oil of dragonhead were consisted of linalool formate, geranyal and geranyl acetate. Three day irrigation interval and application of 4 ml/L produced the most of linalool formate. The amount of geranyal (10.92%) was increased by increasing of irrigation interval and the highest amount was observed with application of 6ml/L fertilizer in six days irrigation interval. The lowest amount of geranyl acetate (29.66%) was observed with no application of fertilizer in three days irrigation interval. By increasing of irrigation interval at level of 6 day, the geralnyl acetate compound was produced highest amount of geranyl acetate (71.99%).
