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.
