Agronomical and technological researches on oregano (origanum onites l.) in diyarbakir ecological conditions

Abstract

Origanum onites L. is one of the most important medicinal and aromatic plant grown in the Mediterranean area and extensively using in many traditional medicinal and culinary since ancient times. This study aims to determine the agronomical and technological characteristics of oregano at four different plant densities (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.
