Seed yam production by minisett technique

Abstract

Yams (Dioscorea spp.) are cultivated in many tropical countries including Papua New Guinea (PNG). Cultivated species of major importance in yam growing areas of PNG are D. alata (Greater yam) and D. esculenta (Lesser yam). In these areas the traditional system of seed yam production involves the use of large planting setts which could have otherwise been used for food. A rapid multiplication technique of producing seed yams using minisetts was adopted and proved successful at Laloki Agricultural Research Station, in the Central Province. The technique in seed yam production using minisetts is discusse.
