Maize (corn)


Maize (Zea mays L.) is the most important grain crop in South Africa and is produced throughout the country under diverse environments. See fuller discussion under “Local business environment” heading.

Successful maize production depends on the correct application of production inputs that will sustain the environment as well as agricultural production. These inputs are, inter alia, adapted cultivars, plant population, soil tillage, fertilisation, weed, insect and disease control, harvesting, marketing and financial resources.

In developed countries, maize is consumed mainly as second-cycle produce, in the form of meat, eggs and dairy products. In developing countries, maize is consumed directly and serves as staple diet for some 200 million people. Most people regard maize as a breakfast cereal. However, in a processed form it is also found as fuel (ethanol) and starch. Starch in turn involves enzymatic conversion into products such as sorbitol, dextrine, sorbic and lactic acid, and appears in household items such as beer, ice cream, syrup, shoe polish, glue, fireworks, ink, batteries, mustard, cosmetics, aspirin and paint.

International business environment

  • With strong demand for maize from food companies, livestock producers and ethanol makers, American maize (corn) production is considered a critical component in global supply and demand. The USA is the largest producer of maize, followed by China, Brazil, Argentina and the EU (USDA, 2023).
  • The largest exporters of maize are Brazil, USA and Argentina (USDA, 2023).
  • Top importers are the EU, China, Mexico, EU, Japan and South Korea (USDA, 2023).

Understanding the Economics of the Maize Industry


The maize market is an open and deregulated market. What you get for your crop is very much what the market prices at the time are.


A number of factors influence what this price is:


  • The international price of maize. People want to save money. If they can buy maize from somewhere else at a price lower than yours, they will do so.
  • The current exchange rate. The balance between the South African rand and the American dollar might make it a bad idea for a miller to buy your maize when he could be getting it cheaper somewhere else. This is the reason why the exchange rate is watched with great interest.
  • Local production (influenced by weather conditions and hectares planted to maize). If there is not a lot of maize around, you will have many people wishing to buy your maize and so the price you get will be higher.
  • Local consumption of maize. If the demand for maize were to drop, then not that many people would be wanting to buy your maize and you would have to settle for a lower price.
  • Production levels in the SADC region (South Africa is usually the main source of white maize for these countries in times of shortage). If a lot of maize has been produced, then the people who buy it will be able to buy from elsewhere if you are wanting too much for yours.
  • Stock levels (both domestically and internationally). How much maize is available? In times of surplus, the price of maize is closer to export parity, whilst in times of shortages the price of maize will be closer to import parity. It should be emphasized that information on outlook and trends of the fundamental factors influence market perceptions of traders which eventually affect the price levels. Credible and timely information, especially on crop estimates, stock levels, imports and exports, is therefore critical for the proper functioning of the market.

Local business environment

Maize is the most important grain crop in South Africa, being both the staple food for the majority of the South African population and the major feed grain. Most of the maize produced in South Africa is consumed locally; as a result, the domestic market is very important to the industry.

  • Maize is produced throughout South Africa with Free State, Mpumalanga and North West provinces being the largest producers, accounting for over four-fifths of total production (DALRRD, 2023). Maize is produced mostly on dry land with less than 10% produced under irrigation.
  • White maize is primarily for human consumption. Yellow maize is the most important ingredient in feed rations for dairy, beef, poultry and egg production. When the price of white maize falls below that of yellow maize, then white maize can also be used for animal feed (BFAP, 2023).
  • The ratio between human consumption vs animal feed, white maize vs yellow maize, is changing for a number of reasons: (i) Maize production is becoming less profitable in the western parts of the country, where most of the white maize is grown (ii) Yellow maize is easier to trade globally, the prices less volatile than for white maize (BFAP, 2020).
  • Maize is planted mainly between mid-October and mid-December. The rainfall pattern and other weather conditions of a particular season determine the planting period as well as the length of the growing season. This planting window is coming later than in previous years, and the period is shorter, placing pressure on farmers (BFAP, 2019).
  • The maize industry is important to the economy both as an employer and earner of foreign currency because of its multiplier effects (maize also serves as a raw material for manufactured products such as paper, paint, textiles, medicine and food).
  • The maize marketing season in South Africa commences on 1 May and ends on 30 April the following year.

Market value chain

The maize market value chain can be broken down into the following levels:

SectorRole players
PrimaryInput suppliers



Silo owners



Animal feed manufacturers

TertiaryTraders (hedgers, arbitrageurs and speculators)



Transporters (used throughout the chain)

For the Newcomer

The Maize Trust currently funds most of its transformation projects through the Farmer Development Programme of Grain SA and by means of the Grain Farmer Development Association (GFADA). Over and above the funding granted by means of GFADA and Grain SA, the Trust also funds transformation projects through projects of the Agricultural Research Council. Find details at

GFADA assists black emerging farmers by paying for, inter alia, soil correction, comprehensive crop insurance and the costs of mentors to assist the farmers for a five year period or longer. By not being limited to funding for one commodity only, GFADA has the added benefit of crop rotation opportunities for the farmers.

BFAP Baselines regularly touch on the comparatively high cost of fertiliser in South Africa, making the cost of producing maize under dryland conditions in South Africa is significantly higher, compared to leading global producers. When you import something like fertiliser, a host of other costs kick in: the exchange rate, deep sea freight rates, unloading- and administrative cost at ports and inland transportation. What can be done about this?
