Abstract
Nitrogen significantly increased essential oil yield of chamomile and influenced its composition. Phosphorus did not have similar effects but low rates of P (17.47 kg P/ha) tended to increase essential oil yield. High phosphorus rates decreased essential oil yield. Application of 17.47 kg P/ha at transplanting and top-dressing later with 50 kg N/ha gave the best results.
