Effect of foliar nutrition on the essential oil yield of Thyme (Thymus vulgaris L.)

As shown by our field experiments, targeted pre-harvest application can significantly increase the yield of EOs, resulting in a quantitative increase in the EO content of the plants, ranging from 18.76% to 42.47% compared to untreated plants. In addition, EOs obtained from the treated plants were found to contain 62.1-64.1% thymol; this range was more stable compared to untreated plants, where the thymol content ranged between 53.1% and 62.7%.
