N-fixing legume, soil fertilizer and rotation crop
Bambara groundnut is a N-fixing legume and thus a fertilizer for the soil. It is a good companion/rotation crop that returns N to the next crop. It does not require additional fertilizer. It is generally intercropped with cereals (maize, sorghum, and pearl millet), other legume grains (cowpea, groundnut), root and tuber crops, or vegetables (Brink et al., 2006).
