Vetiver (Vetiveria zizanioides (Stapf.) is grown in Burundi for its anti-erosive properties. A study to determine the effects of organic manure or a combination of organic manure and NPK fertilizer was performed. Criteria such as root yield, effect on harvest time, oil yield, oil quality and composition were examined. It was found that soil treatments increased the root yield from 1,500 kg/ha to ca 2,400 kg/ha, while harvest time effected oil quality and yield. Also the khusimol content ranged from 19.4-29.5%, and some oils were judged as having superior quality.
