In medicinal plants increasing both essential oil yield and herbs yield are important. For this purpose open field soilless culture can be used. In this method soilless culture and conventional culture advantages combined together to increase yields, especially in medicinal plants. In this research two systems: Trench culture and Bag culture designed. These systems were different in sun light exposure. The treatments were three media included: coco peat 100%, perlit 100% and perlit-cocopeat 50-50 V/V used in each system. After system setting up, nutrient solution used for each plant equally. In conventional culture manure mixed with the soil before planting. Statistical design was split plot in randomized complete block design. The main plot was systems (in two levels) and subplot was media (in three levels). Each treatments had 3 replicate. Generally in most growth factors, coco peat media had most values. Because of inability of Perlit media for water and nutrient adsorbing between irrigations, caused the plants growth limitated. Therfore, most growth factors in both were lowest in perlit. Water use per plants in conventional culture was 18.6 times more than soilless culture. Essential oil yield in conventional culture for growth limitation was lower than all media in soilless culture systems.
