Abstract
Cyclea barbata Miers can be used in pharmaceutical industries and food. They are of tropical origin, and thus suitable for cultivation in many places in Vietnam. This study was conducted to evaluate the effects of different types of growing media on growth, seedling quality of root cutting of Cyclea barbata and fnancial efciency at the nursery stage. A one-factor experiment was arranged in a completely randomized design with three replicates and nine treatments which were different mixtures of sand, rice husk ash, coco peat and vermicompost with different ratios in volume. The results showed that root cutting of Cyclea barbata was planted on the mixed media of 25% rice husk ash: 50% coco peat: 25% vermicompost gave the highest number of roots (17.23 roots/cutting), shoot length (100.48 cm), number of leaves (14.70 leaves/cutting), fresh and dry root matter (3.71 and 0.48 g/cutting), fresh and dry shoot matter (5.45 and 1.50 g/cutting), seedling quality index (0.019) at 75 days after planting, the proft (3,665,800 VND/1000 cuttings) and a proft margin of (0.73 times).
