Maize
Maize
Zea mays L.
A major cereal raw material with wide applications in human food, animal feed, flour and grits, starch, oil, brewing, fermentation and other industrial processing activities. Its grain, fresh cob, bran, germ and other fractions support multiple value-added opportunities across the Nigerian agricultural and industrial value chain.
Maize Overview
Maize (Zea mays L.) is an important cereal crop grown widely in Nigeria and across sub-Saharan Africa. It is used directly as food and is also an important raw material for animal feed and agro-industrial processing.
The maize value chain extends from seed and input suppliers through farmers, aggregators, traders, storage operators, processors and industrial users. Processing can produce flour, grits, meal and other food ingredients, while maize fractions can be utilized in feed, oil, starch and fermentation-related applications.
For NRMH, maize is treated as a multi-use industrial raw material rather than only a food grain.

Production Data & Data Interpretation
National maize production estimates differ between datasets because they may use different years, methodologies, production boundaries and estimation procedures. NRMH therefore avoids presenting one historical production figure as a permanently current national figure.
NAERLS has published national agricultural performance data containing maize cultivated-area and production estimates, while IITA and FAO publish additional sector-level information. These sources should be referenced according to their specific reporting year and methodology.
