The root crop Nigeria shouldn’t ignore is the sweet potato, a humble yet nutritionally potent and economically rewarding plant that has long remained in the shadow of cassava and yam.
Despite its superior nutritional profile, climate resilience, and quick maturity, the sweet potato is often overlooked in national agricultural policies and commercial investments.
Yet, across the globe, it is being repositioned as a critical crop for food security, economic growth, and rural empowerment.
In Nigeria, the untapped potential of sweet potato remains vast and promising, especially at a time when the country seeks to diversify its economy beyond oil and tackle rising food insecurity.
Sweet potato, botanically known as Ipomoea batatas, is a root tuber with a sweet taste and soft texture when cooked.
It is cultivated in many parts of Nigeria, particularly in the Middle Belt and Northern regions such as Benue, Plateau, Nasarawa, Kaduna, and Kwara States.
Although it requires relatively low input, it yields generously and matures within a short period—typically between three to five months.

This early maturity offers an excellent opportunity for smallholder farmers to achieve multiple planting and harvest cycles within a year, thereby increasing their income streams.
One of the most compelling attributes of sweet potato is its nutritional profile.
The orange-fleshed varieties, known globally for their high beta-carotene content, play a crucial role in combating vitamin A deficiency—a major public health issue in Nigeria, especially among children and pregnant women.
The crop is rich in dietary fiber, complex carbohydrates, antioxidants, and essential vitamins and minerals.
Beyond consumption, sweet potato leaves are also edible and packed with nutrients, making the crop a complete food source with both economic and nutritional value.
In terms of global recognition, sweet potato is experiencing a renaissance.
Countries like China, the United States, and Uganda are aggressively investing in its production and value chain.
International organizations such as HarvestPlus, USAID, and the International Potato Center (CIP) have continued to promote the orange-fleshed sweet potato (OFSP) in Africa due to its potential to eradicate hidden hunger.

Nigeria, with its favorable agro-ecological zones and large farming population, is uniquely positioned to become a leader in sweet potato production, processing, and export if deliberate steps are taken.
Unfortunately, despite these advantages, the sweet potato remains marginalized in national agricultural planning.
Most government interventions and subsidies continue to focus on cassava, maize, and rice, while sweet potato cultivation is largely left in the hands of peasant farmers with minimal extension support.
This neglect has led to poor yields, lack of improved varieties, inadequate storage facilities, and minimal investment in processing and packaging infrastructure.
Yet, sweet potato holds enormous commercial potential.
The crop can be processed into a variety of products including flour, starch, chips, puree, baby food, pastries, and even alcohol.
Its flour is gluten-free, making it an excellent alternative for people with celiac disease or those on specialized diets.

Its starch is used in textiles, pharmaceuticals, and adhesives. Furthermore, the dried roots and vines serve as excellent feed for livestock.
These value addition opportunities, if properly developed, can stimulate agribusinesses, create jobs, and increase Nigeria’s export earnings.
Modern agriculture is not merely about production, but about value chains—systems that connect farming to processing, marketing, and distribution.
The sweet potato value chain in Nigeria remains rudimentary, but ripe for development.
Entrepreneurs, agritech innovators, cooperatives, and processors must recognize the economic viability of this crop.
Establishing cottage industries for sweet potato flour and chips, investing in cold storage systems, and training farmers on post-harvest handling techniques can drastically reduce losses and improve profitability.
Furthermore, the global market for sweet potato products is expanding rapidly.
Countries in Europe and North America are increasing their imports of dried and processed sweet potato due to its health appeal.
Nigeria can plug into this market by meeting international standards on quality, hygiene, and packaging.
To do this, public-private partnerships and deliberate policy shifts are essential.
Government agencies must provide improved varieties, offer training on good agricultural practices, and incentivize mechanization to boost productivity.

The role of research institutions is also critical. Organizations such as the National Root Crops Research Institute (NRCRI) must intensify efforts to develop and distribute high-yielding, pest-resistant, and climate-smart sweet potato varieties.
These varieties should be accessible to farmers at affordable rates, along with complementary training in agronomic practices.
In addition, universities and polytechnics can drive innovation by encouraging research into sweet potato processing technologies, product diversification, and export readiness.
The sweet potato revolution must also be inclusive. Women and youth, who form a significant portion of Nigeria’s rural farming population, should be strategically engaged in the value chain.
Targeted empowerment programs, financial access, and market linkages can position sweet potato farming as a dignified and profitable venture for unemployed graduates, widows, and young entrepreneurs.
Cooperatives and community-based organizations can further enhance access to markets, inputs, and shared processing facilities.
Another dimension that must be explored is the climate-smart nature of sweet potato.
As Nigeria continues to face the brunt of climate change—marked by irregular rainfall, flooding, and drought—sweet potato offers a resilient alternative.
Its relatively short growing cycle and adaptability to various soils make it a viable crop even in marginal conditions.
Promoting its cultivation can serve as a climate adaptation strategy while simultaneously ensuring food availability during off-seasons.

To fully unlock the potential of this crop, awareness campaigns must be launched across traditional and digital platforms.
Sweet potato should not only be promoted as food but as a business, a health solution, and a development catalyst.
Government agencies, non-governmental organizations, the media, and influencers must contribute to this rebranding effort.
When more Nigerians understand the full benefits of this crop, both its consumption and investment appeal will rise significantly.
The path forward is clear: Nigeria must reimagine its agricultural priorities to include crops that are climate-resilient, nutritionally superior, and commercially viable. Sweet potato checks all these boxes.
By neglecting it, we risk missing a strategic opportunity to tackle malnutrition, create jobs, grow exports, and uplift rural livelihoods.
In conclusion, the sweet potato is not just another root tuber—it is a silent giant waiting to be awakened. Its time has come.
As Nigeria strives to achieve food sovereignty, economic diversification, and improved public health, the country must harness the power of this underrated crop.
With strategic investment, farmer education, and value chain development, sweet potato farming could very well be one of the keys to unlocking Nigeria’s agricultural future.
