Thymus daenensis is a medicinal plant endemic to semi–arid regions of Iran. A field experiment using a randomized complete block design with four replications was conducted to evaluate the effect of 20, 50 and 80% soil water depletion on morpho–physiological traits, essential oil content and composition and water use efficiency of T. daenensis during 2010–2011. Water stress reduced growth, herbage roduction, chlorophyll and carotenoid content, while increased proline, K +, essential oil content and irrigation water use efficiency based on essential oil yield (IWUE eso). Thymol was the highest essential oil composition (63.3–73.5%) followed by carvacrol (3.6–16.0%), ρ–cymene (3.8–7.4%), γ–terpinene (3.3–4.7%), β –caryophyllene (2.8–4.0%) and borneol (1.4–3.4%), respectively. Thymol, ρ–cymene and γ–terpinene were increased, while the other compositions decreased under water stress. It is concluded that irrigation of T. daenensis based on 50% water depletion should be an appropriate choice for first growing season and 80% water depletion for the second growing season in semi–arid climatic conditions.
