It has been found that A. annua is relatively easy to grow and that very high biomass yields (35t/ha) can be obtained in the Midwest. Plant spacing had a highly significant affect on biomass yield and plant architecture. Wide variation in artemisinin content has been found in our germplasm collection with accessions reaching 0.21%, and individual plants as high as 0.39% (dry weight basis). This suggests that high artemisinin yields lines could be developed by further selection and breeding. The commercialization of A. annua in this country is dependent upon whether artemisinin or its derivatives will be approved for use in the treatment of malaria. Domestic production of A. annua for the extraction and processing of artemisinin for export should be considered as overseas markets develop and if they will purchase imported materials.
Artemisia has potential as a source of essential oils and we have obtained oil yields of 85 kg/ha. Uses of the essential oil from A. annua in the fragrance industry would provide an additional market and a new use for this species.
