One of the important requirements in agronomic planning is the use of various non-chemical plant systems. In order to investigate the effects of vermicompost and humic acid on Myrtus communis, an experiment was conducted in a factorial experiment in a randomized complete block design with 16 treatments and 3 replications at the Alborz Research Station, Research Institute of Forests and Rangelands of Iran. Treatments included vermicompost (9, 18, 27, 36 and 45 t/ha), Hiumic acid (5, 7.5, 10, 12.5 and 15 l/ha), five combinations of them (V9+H15, V18+H12.5, V27+H10, V27+H7.5) and control. There was significant diference between treatments in shoot, leaf, essential oil yields and essential oil percentage. The highest leaf yield (356 kg ha-1), shoot yield (773kg/ha) essential oil percent (1.86%) and essential oil yield (14kg/ha) acheaved in treatment of 45 tons per hectare vermicompost. The main components of the essential oil were α-pinene (5.63-48.5%), limonene (3.4-22.6%), 1.8-cineole (2.2-18.7%), linalool (7.96-26.7%), myrtenol (2.1-19.2%), trans- carveol (0.1-2.5%) and α-terpinyl acetate (1.8-7.7%) .
