摘要：The changes in herbage yield, esntial oil yield and chemical composition of the esntial oil of ro-scented geranium ( Pelargonium sp.) cv. Bourbon were investigated in the prence and abnce of weeds during different periods of crop growth. The crop, which was kept weed-free for the first 30 or

Therefore, the ro-scented geranium crop should be kept weed-free, either during the first 90 days after planting or during the last 90 days before harvesting, to obtain high herbage and esntial oil yields.
