BAMBARA GROUNDNUT (Vigna subterranea) - POTENTIAL FOR VALUE
CHAIN IN NIGERIABy:
ATOYEBI, O.J., ABBERTON, M., OYATOMI, O. A. OSILESI, O. and ADEBAWO, O .O.
Introduction
• Bambara groundnut (Vigna subterranea (L.) Verdc.) is an annual, creeping legume with glabrous, trifoliate leaves.
• It is cultivated primarily for its seeds, which are used as human food. In Africa, it is the third most commonly eaten legume after groundnut and cowpea (Omoikhoje, 2008).
• It’s a complete food, yet a NUS.
BG growing plant
•
.. Presently 1973 BG collections are in the IITA genebank.
. Work on 300 are being done for GD studies using morphological description and DArT.
Nutritional importance
• BG contains • 60% carbohydrate, • 20% protein, • 6% oil • It also contains micronutrients like zinc (0.81mg),• iron (2.51mg), phosphorous (0.21mg),• calcium (2.19mg) e.t.c., per 100g of the nut.• (Abdusalam and Sheriff, 2010).
Promoting Utilisation
• Promoting BG food products / utilisation needs to involve Improved value chain for the crop.
• Adequate awareness of its nutritional importance.
Promoting Utilisation
• BG do well even under extreme conditions.
• Annual world production stands at 300,000 tonnes; predominantly from W/A.
• The yield is ranging between 300 – 800 KG / Hectare.

BG Research constraints
• Hardness of the seeds.
• Long cooking time.
• Anti-nutrient factors.
• A NUS species.
Conclusion
BG and its products, due to its immense nutrient potentials, if well utilised, can serve as a future crop that can assist developing countries, towards solving the problems of malnutrition (hidden hunger) and food insufficiency.
