Abstract

This research was carried out to examine the effect of phosphorus fertilizer applications on the essential oil ratio and essential oil components of Origanum vulgare subsp. Hirtum. Experiment randomized parcels were planned in 4 replicates according to experiment design and four different doses of phosphorus fertilizer (0, 0.5, 1 and 1.5 Kg P2O5 ha-1 ) were applied. Plants grown in greenhouse conditions were harvested at the end of the seven month cultivation period. At the end of the harvest, the effect of phosphorus applications on the essential oil content of the plants was found to be statistically insignificant. No significant change was observed with phosphorus applications in the rate of carvacrol which is the main component of the essential oil of the plant. While a positive change was observed in the ratio of cymene, one of the essential oil components of the plant, with phosphorus applications, a negative change was observed in the ratios of some essential oil components such as β-ocimene and α-farnese.
