Abstract

The purpose of this study was to determine the effects of different nitrogen doses (0, 6, 12 and 18 kg/da) on the plant parameters, yields and quality of Artemisia annua L. ecotype from Adana, Turkey. A two-year experiment was conducted between 1996-1998 under Adana ecological conditions. During this study, plant height (cm), number of branches per plant, fresh herb yield (kg/da), dry herb yield (kg/da), dry leaf yield (kg/da), essential oil content (%) essential oil yield (1/da), artemisinin content (%), and artemisinin yield (kg/da) were investigated, The results indicated that application of different N doses statistically affected the essential oil content and oil yield only the first year of the study. But artemisinin content and yield were not significantly affected. © 2002 by The Haworth Press, Inc. All rights reserved.
