This study aims to determine the agronomical and technological characteristics of oregano at four different plant densities insert ignore into journalissuearticles values(70x20, 70x30, 70x40, 70x50 cm); and two harvests. The effects of this application was noticed on the fifteen flowing parameters; plant height, fresh and dry herb yield, dry leaf yield, canopy diameter, essential oil content and essential oil composition etc. According to the results; significant differences were found statistically between harvests, in all properties being studied; except dry herb yield. Fresh and dry herb yield varied from 11.1 to 13.7 t ha–1 and from 3.8 to 5.0 t ha–1 per harvest, respectively in a year. Dry leaf yield varied between 1.7–2.9 t ha–1 per harvest in a year. Carvacrol, 1,8 cineole and γ-terpinene were found as major components of oreganos. Mean Carvacrol percentage determined as 53.9%, 1,8 cineole 9.7% and γ-terpinene as 5.7% respectively.
