15 Economic importance of maize to man

Maize, also known as corn, is a staple food crop grown in many parts of the world. It is one of the most important cereal crops, providing food and income to millions of people. Maize is also used in a variety of other applications, including animal feed, industrial products, and biofuels. In this essay, we will explore 15 economic importance of maize.

Economic importance of Maize/Corn

Food security

Maize is a major source of food for millions of people in Africa, Latin America, and Asia. It is a versatile crop that can be grown in a range of climates and soil types, and it can be stored for long periods of time without spoiling. As such, it plays a critical role in ensuring food security in many parts of the world.


Maize farming creates jobs for millions of people around the world. From planting to harvesting, maize farming requires a significant amount of labor, and the processing and distribution of maize products also provide employment opportunities. In many rural communities, maize farming is a major source of income for families.

Livestock feed

Maize is an important ingredient in animal feed, particularly for poultry and pigs. It is a high-energy feed that helps to promote growth and improve the health of livestock. The demand for maize as animal feed is increasing as the demand for meat products grows around the world.

Ethanol production

Maize is a key ingredient in the production of ethanol, a biofuel that is used to power vehicles. The use of ethanol as a fuel source is growing as countries seek to reduce their reliance on fossil fuels and lower their carbon emissions. The production of maize-based ethanol creates jobs and contributes to economic growth.

Industrial uses

Maize is used in the production of a variety of industrial products, including adhesives, paper, and textiles. It is also used in the manufacture of plastics, pharmaceuticals, and cosmetics. As such, the demand for maize as an industrial raw material is increasing.

Export earnings

Many countries earn significant amounts of foreign exchange through the export of maize and maize products. The global market for maize is large, and countries with a comparative advantage in maize production can earn substantial income from exporting the crop.

Drought tolerance

Maize is a relatively drought-tolerant crop, meaning it can survive in areas with low rainfall or during periods of drought. This makes it an important crop in regions with unpredictable weather patterns or limited access to water resources.

Crop rotation

Maize is often used as part of a crop rotation system, in which different crops are grown in the same field in successive seasons. This helps to improve soil health, prevent soil erosion, and reduce pest and disease pressure. As such, maize farming can contribute to sustainable agriculture practices.

Genetic diversity

Maize is a highly diverse crop, with thousands of different varieties grown around the world. This genetic diversity is important for ensuring the resilience of maize crops in the face of pests, diseases, and changing environmental conditions.

Research and innovation

The study of maize genetics, breeding, and cultivation has led to significant advances in agricultural science and technology. Research into maize has led to the development of new varieties with improved yield, drought tolerance, and disease resistance, as well as new farming techniques and technologies. This ongoing research and innovation are critical for ensuring the continued success of maize farming in the future.

Contribution to GDP

Maize is a major contributor to the gross domestic product (GDP) of many countries. In some countries, such as Mexico and Zimbabwe, maize accounts for a significant portion of the national GDP. The income generated from maize farming and processing supports local economies and helps to drive economic growth.

Food processing industry

Maize is an important ingredient in many food products, including corn flakes, corn syrup, and corn oil. The food processing industry relies on a steady supply of maize to meet the demand for these products. This industry creates jobs and contributes to economic development.

Human nutrition

Maize is a good source of carbohydrates, fiber, and certain vitamins and minerals. It is an important part of the diet for millions of people around the world, particularly in regions where other food sources may be limited. The availability of maize can have a significant impact on the health and wellbeing of local populations.


Maize is a bio secured crop, meaning it is less susceptible to contamination by pathogens and pests than some other crops. This makes it an important crop for regions where biosecurity is a concern, such as areas affected by plant diseases or pests.

Climate resilience

Maize is a relatively resilient crop that can tolerate a range of growing conditions. As such, it is well-suited to the changing climate patterns that are affecting many parts of the world. By providing a stable source of food and income in areas affected by climate change, maize can help to improve resilience and adaptability.

In conclusion, maize is an important crop with many economic benefits. From food security to industrial uses, from employment to genetic diversity, maize plays a critical role in the global economy. As such, efforts to support and improve maize farming can have far-reaching benefits for millions of people around the world.
