Oregano essential oil is rich in carvacrol and is recently the subject of a great interest for its use in the production of feed additives, mainly for his antimicrobial properties. The French region of Franche-Comté launched a project to determine the economic potential of this new culture. Three commercial varieties of oregano, Carva, Origalia and Bolier were evaluated on three sites with very different soil and climate conditions in the departments of Jura and Haute-Saône, from 2004 to 2006. This lamiacea revealed very well suited to relatively hard climatic conditions in this region. Cultivars Carva and Origalia proved to be the richest in essential oil (7.5 %). They are also better suited to the altitude sites. The good strength of Carva is even an advantage in the 1st year of harvest, with higher average yields. With a potential production within two years of 400 l/ha of essential oil with a carvacrol content of 75_80 %, oregano culture can be considered as a valuable source of natural carvacrol for the industry.
