Seed yam is costly, and can carry pests and diseases. To reduce costs and to manage seed health, in the 1970s, the Yam Minisett Technique (YMT) was developed, which involved cutting yams into small pieces to be used as seed. Few farmers adopted the technique, in part because of the high labor req...
