The use of medicinal plants has long been common in Iran and other countries. In order to investigate the application of zeolite to improve water use efficiency of Salvia officinalis in different irrigation regimes, a split plot experiment was conducted in a randomized complete block design with three replications in 2018. The experiment consisted of two levels of irrigation regime (normal irrigation (30% of available moisture depletion) and water deficit stress (60% of available moisture depletion) and two levels of zeolite (without zeolite and 10 t ha-1 zeolite). The results showed that in irrigation treatment, the highest essential oil content was 0.88% in irrigation after 60% moisture depletion and in zeolite application the lowest essential oil percentage was 0.81% at 10 t ha-1 zeolite. The highest water use efficiency was obtained 17.68 g L-1 for water deficit stress and 10 t ha-1 zeolite. So depending on the purpose of the study, application of zeolite under water stress can be used to increase the essential oil content and water use efficiency.
