Abstract
Thymus syriacus Boiss., is a narrowly distributed species from Middle East having high content of carvacrol. In the present study, field experiment was conducted to study the influence of organic and mineral fertilizers on essential oil content and components of T. syriacus in East Mediterranean Region of Turkey. The treatments were as follows control (no fertilizer), mineral, vermicompost and manure. In the first year of experiment, control and manure has same significance effect on essential oil while, vermicompost and mineral fertilizer increased essential oil content. Second year of experiment, all fertilizer applications had significantly improved essential oil content compared with control. Essential oil composition was determined with Gas Chromatography Mass Spectrometry Method (GC/MS). Carvacrol and o-cymene were found as main components with their rate depending on the year and application. Carvacrol content were ranged between 62.98-84.56%, while highest content was found ate second year vermicompost applied samples. As a result, for essential oil content and components fertilizers application and especially vermicompost organic fertilizers could be use for cultivation of T. syriacus.
