Field Performance of Seed Yam Dioscorea rotundata Poir) Derived from Tissue Culture and Aeroponics Seedlings
Yam plays an important role in the livelihoods of people in the yam growing regions of the yam belt in West Africa. It forms the dominant crop in these areas and serves as an important source of income to the people [1] The crop is generally cultivated from farmers' saved seed yams from previous harvests. This traditional way of cultivating yam usually leads to significantly low yields as a result of a build up of pests and diseases accumulated through recycling of infested seed yams [2] Tuber yield weight of 20 30% is lost annually at harvest as a result of pests and diseases of seed yam [3]
