Propagation
Seed - not normally used to propagate this species. Cuttings of tubers. Pieces of tuber, each weighing around 50 - 80g with dormant buds, are planted in situ 4 - 8cm deep with the stem pointing downwards[ 300 ]. The cut tuber is often first left in the sun for several hours to promote wound healing and reduce the risk of fungal infection

Marketing
There are approximately 600 species of yam (Ozo et al. 1984) but the species cultivated in the Philippines are Dioscorea alata or ubi and Dioscorea esculenta or tugui (BAS 2006). Annual production of ubi in the Philippines
is 26,464 metric tons for the period 2000-2005, while that for tugui is 2,702 metric tons (BAS 2006). However, consumption for the same period averaged only 5.0% for ube and 14.0% for tugui (BAS 2006).
