Sweet Potato Boom Lifts Incomes In Zaka And Bikita
By 6am along the dusty road between Zaka and Bikita, the verges are already alive. Bakkies grind to a halt, pushcarts creak into place, and heaps of freshly dug sweet potatoes turn the roadside into an open-air market. For many families here, these tubers now pay school fees, drill boreholes, and keep food on the table.
Sweet potato farming is fast becoming one of the most important cash earners for smallholders in Zaka and Bikita districts in Masvingo Province. What began as a traditional food crop has shifted into a commercial venture that is improving household livelihoods, strengthening food security, and nudging rural economies into a higher gear.
How Sweet Potatoes Became Cash In Zaka
In the Rumwanda Resettlement Area of Zaka, the Rwatirera family has turned sweet potatoes into a business plan.
This season, they put four hectares under the crop and are expecting an average of eight tonnes per hectare – a scale many smallholders once associated only with maize or tobacco.
“We have been growing sweet potatoes for some time, but we started increasing our hectarage of late,” said Ms Irene Rwatirera, pausing between customers at her homestead. “This season we did four hectares, and we expect eight tonnes per hectare. We have been surviving through this venture, and we are managing to send our children to school. We also managed to drill two boreholes, and now we are also into horticulture and poultry farming, but our main source of income is sweet potato farming.”
The Rwatireras now use income from sweet potatoes to irrigate vegetables, keep poultry, and cover day-to-day costs. It is a picture of the kind of diversified rural enterprise that aligns with Zimbabwe’s National Development Strategy 1 (NDS1) and the African Union’s Agenda 2063 goal of modern, productive agriculture.

Sweet potatoes are a drought-tolerant root crop that can produce reasonable yields with less rainfall than maize. They mature in a few months, provide both food and income, and can be grown in small plots or larger fields. Because they are relatively hardy, they are an attractive option for smallholders facing erratic rainfall and rising input costs.
Why Sweet Potato Production Matters For Food Security
Agricultural officers working in Masvingo Province point to sweet potatoes as one of the crops that can anchor climate-smart food systems. In years when maize fails, families that planted sweet potatoes often still harvest something edible and sellable.
That dual role – as food and cash – is what gives the crop outsized power in districts like Zaka and Bikita, where many households still rely on rainfed agriculture and have limited access to formal credit.
Farmers in Zimbabwe and across the region increasingly see sweet potatoes as part of a diversified crop mix that can cushion households against price shocks and poor rainfall, while contributing to national efforts under the UN Sustainable Development Goals to end hunger and reduce poverty.
How Farmer Field Schools Are Raising Yields
Inspired by families like the Rwatireras, farmers in Rumwanda formed the Goldenbite Tubers Farmer Field School, a learning group supported by agricultural extension officers from Agritex.
FFA Explainer:
A farmer field school is a group of farmers who meet regularly in their fields to learn by doing, often guided by an extension officer. They experiment with different practices, share results, and agree on what works best in their local conditions. The model has been used across Africa to spread practical knowledge quickly among smallholders.
“Our group of sweet potato farmers has brought us together to learn and support each other,” said farmer Mr Peter Mukarati. “We are a group with membership of nearly 50 farmers, and we work with Agritex officers who train us on improved farming methods, pest and disease management, and proper crop handling. Because of this knowledge, our yields have improved, and many households are now earning a decent income from sweet potato farming.”
Field school members compare varieties, test planting densities, and learn simple grading and packaging techniques that make their tubers more attractive to buyers. They also share information on local markets, from township vendors to buyers coming from as far as Harare and Bulawayo.
These peer groups mirror similar initiatives in other parts of Zimbabwe, where farmers have organised around crops such as biofortified maize and groundnuts to improve quality and bargaining power.
What Holds Farmers Back From Scaling Up?
Despite the progress, farmers say several barriers are limiting how far they can go with sweet potato commercialisation.
“We are happy with the progress we have made so far, but drought remains one of our biggest challenges,” said Ms Joyce Matereke, another farmer in the area. “If only we can irrigate our fields, then we can have improved yields. We also need tractors to prepare our land on time and support in acquiring export licences so that we can access bigger markets. With those opportunities, we believe we can increase production and improve our incomes even further.”
Her concerns echo a wider set of constraints facing smallholders across Zimbabwe:
- Limited access to small-scale irrigation and water harvesting.
- Shortage of affordable tillage services and mechanisation.
- Weak links to formal buyers and processing companies.
- Complex, often costly, processes to access export markets.
For women and youth in particular, accessing finance for pumps, drip kits, or even improved planting material can be difficult. Yet these groups are central to the sweet potato story in Masvingo – they do much of the planting, weeding, harvesting, and selling.
Government programmes under NDS1 that promote irrigation rehabilitation, mechanisation, and rural agro-processing offer an opening. The challenge is to ensure districts like Zaka and Bikita are not last in the queue and that women and young agripreneurs can participate directly, not only as labour but as business owners.
Roadside Markets Turn Tubers Into Cash
On the tarmac linking Zaka and Bikita, the sweet potato economy is most visible. Makeshift stalls, sacks piled high, children sorting tubers by size – this is where farmers turn harvests into hard cash.
“Sweet potato farming is now our source of livelihood,” said vendor Ms Bianca Mugwera, arranging mounds of washed roots under a shade structure. “We bring our produce here every day and sell it to motorists and traders. The money we earn helps us buy food, pay school fees, meet medical expenses and support our families.”
These informal markets might look chaotic, but they are highly organised systems in their own way. Farmers arrive at dawn to secure the best spots. Buyers know which vendors usually have consistent quality. Prices fluctuate with supply, school term dates, and public holidays.
For many households, especially those without bank accounts or formal jobs, these daily cash sales are their financial system. They save in livestock, building materials, or school uniforms instead of deposit slips.
Similar sweet potato trading spots are emerging in other districts, from Nyanga to Gokwe, as farmers look for reliable products with strong demand. Many of these hubs connect into broader value chains that include town markets, supermarkets, and emerging agro-processors.
Can Value Addition Unlock More Income?
Agricultural experts in Masvingo say Zaka and Bikita now have enough production to justify investments in processing and packaging, which would help farmers capture more value and reduce post-harvest losses.
“Our vision is to see this area moving beyond primary production of sweet potatoes into value addition,” said Mr Bright Chanakira, an Agriculture Business Advisor in the Ministry of Agriculture, Mechanisation and Water Resources. “The community and we from the government are looking forward to the establishment of a sweet potato processing centre that will create employment, reduce post-harvest losses and enable farmers to realise more value from their produce.”
A local processing centre could produce flour, chips, dried slices, or even animal feed from off-grade roots. It could also create jobs in washing, slicing, packaging, and logistics, particularly for young people who do not have land.
Across Africa, projects supported by organisations such as the FAO and the African Development Bank have shown that once farmers can supply consistent volumes, processors are more willing to invest in rural areas. Zimbabwe’s own thrust towards rural industrialisation under NDS1 points in the same direction.
For Zaka and Bikita, the building blocks are taking shape: organised farmer groups, rising production, local trading hubs, and a clear interest from government advisors. What is missing are the catalytic investments – in storage, processing equipment, business training, and market linkages – that could turn this momentum into an anchor industry for the districts.
Lessons For Smallholders Across Zimbabwe
The sweet potato story unfolding in Zaka and Bikita carries lessons for other rural communities across Zimbabwe and the wider region.
- Diversification pays. Families like the Rwatireras are using sweet potatoes to finance other ventures – from horticulture to poultry flocks. That mix spreads risk and multiplies income streams.
- Organised learning lifts productivity. The Goldenbite Tubers Farmer Field School shows that when farmers learn together, yields and quality improve.
- Women’s leadership is central. Many of the visible faces in production and marketing are women like Irene, Joyce, and Bianca, whose decisions shape how income is used in the household.
- Local markets matter. Before big exporters arrive, roadside markets and town vendors often provide the first real commercial opportunity.
For policymakers, the message is clear: support to sweet potato systems – from seed to storage to processing – fits squarely within food security goals and rural development targets under Agenda 2063 and the SDGs. For banks and agribusinesses, the steady stream of tubers on the Zaka–Bikita road is a signal that there is volume, organisation, and appetite for growth.
Back in Rumwanda, as the dry season dust settles on another truckload of harvested roots, Irene Rwatirera looks across her four hectares with quiet confidence. The crop beneath the soil is no longer just subsistence. It is school fees, clean water, chickens in the run, and a reason for young people to stay connected to the land.
If the vision of a local processing centre becomes reality, the sweet potato boom now transforming family budgets in Zaka and Bikita could yet power a new chapter of rural industry – one sack, one roadside sale, one season at a time.
