Cassava is one of Nigeria’s most ubiquitous crops, a staple food eaten daily as garri or fufu. But for Yemisi Iranloye, cassava became much more than just a dependable source of sustenance. She transformed it into an industrial powerhouse. This is the story of how the cassava industry in Nigeria was revitalized through science-driven entrepreneurship and rural value-chain investment.

From Weekend Hobby to Industrial Vision

Iranloye first experimented with cassava as a weekend hobby; buying a small plot in Oyo State, multiplying superior cassava stems and sharing them with neighboring farmers to raise yields. Her formal scientific training informed her vision: a degree in food biochemistry and nutrition and years of work at a Lagos glucose syrup plant gave her deep insight into root crop chemistry. This blend of academic knowledge and grassroots practice laid the foundation for Psaltry International, the company she built by placing industrial processing where cassava is grown.

In 2011, at age 40, Iranloye left her salaried work, moved onto her farm and used a loan to build a 20-tonne-per-day cassava starch mill with equipment imported from China. Her decisive innovation was logistical: cassava spoils quickly after harvest, so building processing adjacent to smallholder production cut spoilage, improved quality and shortened the supply chain. That locational advantage helped Psaltry pass demanding quality tests and secure Nestlé as its first major customer; multinational buyers such as Unilever, Nigerian Breweries and Promasidor followed as Psaltry expanded its product range.

Growing the Cassava Industry in Nigeria

Across Nigeria, cassava is better used for garri or fufu, essential starchy accompaniments for soups and stews. But its industrial potential is broad: cassava roots can be refined into starch, ethanol, glucose syrup, flour and sweeteners. Food manufacturers use cassava starch as a binder and thickener. Packaging companies use it in corrugation. Rising demand for gluten-free products has given cassava flour new markets. By treating cassava as an industrial feedstock rather than merely a subsistence crop, Iranloye helped displace some imports and created higher-value market channels for farmers who previously sold raw roots into low-margin chains.

The company’s success shows how value addition can transform national supply chains. By embedding processing in the zones where cassava is grown, Psaltry boosted efficiency, raised quality standards and helped build the cassava industry in Nigeria into a more resilient and globally competitive sector.

Turning Infrastructure Challenges Into Competitive Advantage

When Psaltry set up its first mill, it was “in the middle of nowhere,” without an access road, unreliable power and a seasonal stream that ran dry. The company built its own road, installed generators until grid connections arrived and drilled boreholes for community and factory use. Financially, Iranloye blended loans and public credit schemes to buy equipment and scale operations; operationally, Psaltry invested in farmer training, traceability and stem multiplication so suppliers could meet industrial quality standards. Those investments turned logistical constraints into competitive advantages, delivering higher quality, faster processing and a dependable supply chain that appealed to major buyers.

Scaling Farmer Partnerships and Cassava Products

What began with 17 smallholders grew into a network of roughly 16,000 farmers supplying Psaltry. Expansion came in phases: after the initial starch mill, Psaltry opened a second factory in 2015 to produce cassava flour; in 2022 it added a sorbitol plant after Unilever sought a reliable local supplier. Producing sorbitol domestically helped reduce dependence on imports from Asia and showcased how downstream processing can capture more value within national borders. At each stage, Psaltry emphasized quality control, traceability and predictable procurement, lifting suppliers into market-grade production rather than subsistence selling.

The expansion of the cassava industry in Nigeria not only boosted local manufacturing, it helped reinforce Nigeria’s agricultural economy by creating jobs, reducing import reliance and solidifying new export pathways.

Competition, Economic Shocks and New Crop Frontiers

As Psaltry’s success became visible, competitors proliferated: Nigeria now hosts dozens of cassava processors. But local demand rose too, particularly after naira volatility made imports costlier and import substitution more attractive. Iranloye views this as an opening for broader agricultural industrialization: sweet potatoes (high starch and naturally gluten-free) and coconuts (where nearly every part has commercial value) are promising next wave crops for similar processing approaches. Her perspective mirrors broader development prescriptions: diversify local value chains, encourage agro processing and link smallholders to paying markets to create jobs and build resilience.

Entrepreneurship Lessons From the Farm

Iranloye’s reflections are practical and pointed. Passion for agriculture is nonnegotiable: the sector rewards persistence when markets and infrastructure lag. Deferred gratification matters. She counsels entrepreneurs to reinvest earnings rather than treat early revenues as personal paychecks, separating personal finances from business growth. Finally, iterative learning and persistence were crucial; Iranloye admits she did not have a perfect plan at the start, but steady experimentation revealed viable products and markets.

Why This Story Matters

Psaltry’s rise from experimental stems and a makeshift rural mill to multi-product processing supplying multinational companies shows how applied science, strategic location and farmer partnerships convert staple crops into industry. For policymakers and development practitioners, the lessons are concrete: invest in rural infrastructure, de-risk finance for processors and farmers and scale extension services so smallholders can meet industrial quality. For entrepreneurs, the takeaway is equally clear: patient mission-driven reinvestment and proximity to raw materials can turn agribusiness into a durable engine of local jobs and import substitution.
