Either mono-cropped or intercropped
with maize, cowpea, melon or
vegetables.
 Propagation solely by stem cutting.
 Stem cutting are not more than 10mths.
 Stem cutting are planted vertical, flat or

Tubers are processed into flour which is
high in carbohydrate.
 Leaves are used for soup and stews.
 Stem mainly for propagation.
 Tuber, Leaves, Stems and Roots are
processed into livestock feeds, starch,
chips, pellets, unfermented flour.
 Ethanol for bio-fuel, alcoholic beverage
and malt drink.

Based on variety, soil and nutrient
availability yield varies between 18-31.8
Mt/yr.
 Model prediction 35.5 – 48.4 Mt/yr.
