Maize, Zea mays L. (corn), is the most abundantly produced cereal in the world. Maize, which was domesticated in central Mexico around 1500 BC, was introduced into Africa around 1500 AD, and spread to every corner of the continent within a relatively short period and is now Africa’s most important cereal crop.
It is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits.
