Maize

Maize is South Africa’s second-largest field crop after sugarcane. Article 1 records a gross value of production that topped R20 billion in 2007/08, with roughly 60% of output going to human consumption and the balance feeding livestock, and with the Free State, Mpumalanga and North West producing around 83% of the crop on the 2012/13 baseline. It is grown overwhelmingly on dryland, which ties output directly to summer rainfall.

The region shares the same summer-rainfall maize belt. Zimbabwe harvested 2,824,110 tonnes from 1,928,505 hectares in 2025/26 according to the Cabinet briefing of June 2026, the highest in its history, although ZimStat’s post-harvest survey for the previous season recorded 1,819,819 tonnes against an in-season projection of 2.3 million, a reminder that early estimates run high. Zambia projected 4.9 million tonnes of maize grain for 2025/26, its largest crop on record. Botswana and Namibia are structural importers: Botswana’s local production averages under 10,000 tonnes a year against demand above 100,000 tonnes, and Namibia’s formal white maize production was 69,541 tonnes in 2025, covering 31% of supply.

Article 3 adds the strategic fork that shapes every maize plan: white maize is food, sold to millers for meal; yellow maize is feed, sold to the poultry, pork and dairy chains. They grow the same way and lead different economic lives.

Article 1 explains how South Africa escaped the regional cycle of bumper harvest followed by export ban: it let a market find the price. Maize trades on SAFEX, where a farmer can sell forward and hedge. North of the Limpopo the price is largely announced. Zimbabwe’s GMB set US$364.75 a tonne for 2025/26, down from US$376.48 the season before and US$390 in 2023/24. Zambia’s FRA set a 2026 floor of K6.94 a kilogram, K347 a 50kg bag, and aimed to buy at least 500,000 tonnes. Namibia’s NAB sets a white maize floor that follows the SAFEX price fortnightly, with local white maize averaging N$6,385 a tonne in 2025 against N$5,040 for imports. Botswana’s BAMB prices at import parity with South Africa.

Seasonality follows the harvest. Prices are lowest from May to July when everyone sells and rise toward the end of the year as stocks are drawn down. The farmer who can store and wait often earns more than the farmer who sells at harvest, provided the storage cost and the cost of waiting for the money are less than the price gain. T-M1-04 runs exactly that comparison.

Next: U3. Imports and exports

Maize moves across the region according to who had rain. South Africa exports in surplus years and imports in drought years. Zimbabwe has been the largest buyer of South African maize in recent seasons. Zambia’s record 2025/26 crop left an expected commercial export surplus, with the DRC, Zimbabwe and Malawi its natural markets. Namibia imported 155,218 tonnes of white maize in 2025 and Botswana imports most of its needs.

For the farmer, trade flows set the ceiling and the floor on local prices. In a deficit market the price tends toward import parity, the cost of bringing maize in from South Africa. In a surplus market it falls toward export parity, the price a buyer abroad will pay less the cost of getting it there. Governments in the region respond to surpluses and shortages with export bans and import permits, which is why a maize plan must name the policy risk alongside the weather risk.

Next: U4. The value chain and who buys

The chain runs from seed and fertiliser suppliers through the farmer to the buyer: a marketing board or reserve agency, a trader, a miller or a feed manufacturer. Article 2 shows that the funnel narrows sharply at milling: many thousands of farmers grow maize but a handful of large millers turn it into the meal families buy, and that is where pricing power concentrates. Article 68 shows the other branch: cheap, reliable maize is the foundation of every poultry and pork industry, because feed is the largest cost in producing meat.

For a small farmer the strongest positions in the chain are rarely in bulk grain. They are in seed maize grown under contract to a seed company, in green mealies sold fresh to urban markets at a premium, in feed supplied directly to nearby poultry and pig producers, and in small-scale hammer milling that sells meal locally and keeps the bran as feed.

Next: U5. Market access and barriers

Maize is a lightly certified crop, but the barriers are real. Buyers grade on moisture, foreign matter, broken kernels and disease, and pay less for anything below grade. Aflatoxin, a toxin produced by moulds in poorly dried grain, can make a load unsaleable. Genetically modified maize is grown commercially in South Africa, while Zambia and Zimbabwe have banned it, so seed choice is also a market-access choice. Cross-border maize needs permits and phytosanitary certificates, and export bans can close a border overnight. Namibia closes its border to white maize imports during its local marketing season, which protects its producers until the local crop is sold.

Next: U6. The entry route

Real minimum capital. Zimbabwe’s commercial gross margin guide puts the cost of growing a hectare of maize at about US$1,200 to US$1,300 from cultivation to harvest, before transport and irrigation. At the GMB price of US$364.75 a tonne, that needs roughly 3.3 to 3.6 tonnes a hectare simply to break even, well above the national average yield. On two hectares the gross income at a good yield of five tonnes a hectare is about US$3,650, which leaves a small margin and no return on the land. Bulk maize on a small plot does not beat the land’s opportunity cost from Module C1.

Input choke points. Certified seed and fertiliser must be in hand before the first rains, which means cash or credit three to five months before any income. Late planting cuts yield. Tillage must be hired in time or done by hand.

Offtake options. The marketing board or reserve agency is the buyer of last resort; private millers and feed manufacturers may pay faster; seed companies contract growers for seed maize at a premium; urban traders buy green mealies.

Who to call. In Zimbabwe, the GMB for grain and its input swap, and seed companies for seed-maize contracts. In Zambia, the FRA and private millers. In Botswana, BAMB for contract buying. In Namibia, the NAB and the registered millers. In South Africa, a grain trader or cooperative and SAFEX prices as the benchmark.

The verdict for a small holding. Grow maize on a small plot only as seed maize under contract, as green mealies for a premium fresh market, or as feed for the student’s own poultry or pigs. As a bulk commodity, maize needs scale the small farm does not have.
