The effects of four levels of nitrogen application (0, 40, 80, and 120kgha-1) on plant growth traits, biomass yield, oil concentration and oil yield of Greek oregano (Origanum vulgare ssp. hirtum (Link) Ietswaart) during three cultivation periods following field establishment were examined. The number of stems, branches and inflorescences per plant, LAI, dry matter and oil yield were significantly affected by nitrogen levels above 40kgha-1, showing an optimum mostly at 80kg of Nha-1. No nitrogen-effect on plant height and oil concentration was observed. Nitrogen-induced biomass and oil yield variations were caused by respective variations in tillering, branching, and the number of inflorescences. Cultivation periods, involving both the age- and the weather-effects, affected all traits, except the average internode length. Root surface density in the top 25cm of soil was positively affected by nitrogen with a peak at 80kgha-1, whereas leaf chlorophyll concentration (mainly chlorophyll a) was steadily increasing with nitrogen rate up to 120kgha-1. |
