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, the EU and Argentina (USDA, 2020).
  • The largest exporters of maize are the USA, Brazil, Argentina by a huge margin (USDA, 2020).
  • Top importers are the EU, Mexico, Japan, South Korea, Vietnam and Iran (USDA, 2020).
  • World production of maize is expected to increase from the current 1,1 billion tons to 1,23 billion tons in 2022 (Absa, 2019).

South Africa: exports and imports

Find the latest presentation and other information on the SAGIS website,

  • Most of the 800 000 tonnes of white maize exported by South Africa in 2017/18 went to SADC and other African countries. Yellow maize exports went to Japan, Taiwan and South Korea (SAGIS, 2018).
  • South African exports to Southern African countries face increased competition from Zambia which produces non-GM maize and enjoys a more favourable transport differential than SA (BFAP, 2018).

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 produced throughout South Africa with Free State, Mpumalanga and North West provinces being the largest producers, accounting for over four-fifths of total production. 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.
  • The ratio between human consumption vs animal feed, white maize vs yellow maize, is changing for a number of reasons: (i) A growing middle class population and greater demand for meat (ii) Maize production becoming less profitable in the western parts of the country, where most of the white maize is grown (iii) Yellow maize being easier to trade globally, the prices less volatile than for white maize (BFAP, 2019).
  • 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).
  • Recent drought conditions (2013, 2015, 2016 and 2019) too, have led to more frequent financial losses and debt carry-over. Farmers have looked for alternatives – cotton, soybeans, cash crops, fodder production and increasing income from livestock (BFAP, 2019).
  • The gross producer value (GPV) for maize production is expected to increase from an estimated R30 billion in 2019 to almost R44 billion in 2022, which should allow producers to decrease their levels of debt (Absa, 2019).
  • Improved maize yields over time are attributed to precision farming, mechanisation and improved seed varieties. However, South African farms are less competitive than major international role players on a cost of production basis, mainly due to lower yields and the high cost of selected inputs (BFAP, 2018).
  • 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 local consumption requirements for maize were 10 299 680 tons in the 2017/18 year (SAGIS, 2018).
  • The maize marketing season in South Africa commences on 1 May and ends on 30 April the following year.

BFAP undertook a study for the Maize Trust related to the potential of the domestic value chain to grow and diversify the production of value added goods. Refer to the report “Adding Value in the South African Maize Value Chain”.

Market value chain

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

SectorRole players

Grower points of interest


Options for when there is a maize surplus and prices are low

“There are still a lot of unexplored opportunities in the secondary maize industries e.g. ethanol production and protein extraction. If we invest in the downstream maize industries, we can retain our competitiveness in the grain sectors”, believes Andrew Makenete.


What are the options of using your harvested maize profitably?

  • Store the grain until the prices are better (see the “Grain storage and handling” chapter).
  • Clean the grain, bag it and market it to small maize buyers. Giving them exactly what they want can earn you a premium price. This can include neighbouring livestock farmers, informal traders or those wanting it for household use.
  • Use it for your own livestock.
  • Diversify into a small, on-farm milling operation of your own Long term solutions.
  • Hedge your prices.
  • Plant 50% less maize.
  • Buy (and store) maize instead of planting it! Find the articles on “Moenie mielies plant: koop jou oes” [Don’t plant maize: buy your harvest] and “Moenie mielies plant: Koop oes (deel 2)”.
  • Plant other crops like groundnuts, soybeans or cowpeas. The latter, as a legume, fixes nitrogen in the soil benefiting follow-up crops. Cowpea can be grazed, baled or turned into silage.
  • Diversify into livestock production.

The Maize Trust and assistance to emerging maize farmers

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).

  • There are approximately 3 600 black farmers in the Grain SA study groups and 58 farmers in a 250 ton maize club. More than 120 black farmers are serviced currently as part of an advanced farmer project within the Development Programme of Grain SA.
  • 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.

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.

In terms of growth in gross value of production (2013-2017) and share of total agricultural production value (2013-2017), DAFF (2018) – now DALRRD – placed green mealies and sweetcorn in the top 10 agricultural products.

In a November 2017 report, DAFF said that it was working with the different grain commodity organisations to develop a suite of financial models (production, processing and Research and Development) with state guarantees/incentives. Included was a plan to formalise the integration of smallholder farmers in the grains value chain through South African Futures Exchange 10-ton Black Economic Empowerment White Maize contracts for smallholder farmers producing grain (Parliamentary Monitoring Group, 2017). See Any further developments?

One of ten “Sectoral interventions” suggested in the Agricultural Policy Action Plan (APAP) is in the “Poultry/soya beans/maize integrated value chain”. It was envisaged that supporting the yellow maize sector would help keep animal feed costs down. This was to be done through “more targeted technical and input assistance, and encouraging stronger linkages between commercial and smallholder farmers, and feed companies via efficient market intermediaries such as cooperatives” (page 26). Maize also plays a role in animal feed for intensive beef production (feedlots) too.

Both the APAP and previous BFAP Baselines (2018, 2015) touched 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? Find the Agricultural Policy Action Plan (APAP) discussion on this in the “Fertiliser” article.
