Introduction
Maize, also known as corn (Zea mays), is one of the most widely cultivated cereal crops in Nigeria and across the world. It plays a vital role in Nigeria’s agriculture sector, serving as both a staple food and a major industrial raw material. Maize is grown by millions of smallholder and commercial farmers across all geopolitical zones in Nigeria, making it a cornerstone of food security and economic development.
Importance of Maize in Nigeria
Maize is important in Nigeria for several reasons:
- Food Security: It is a staple consumed in various forms, including pap (ogi/akamu), roasted corn, maize flour, and maize porridge.
- Animal Feed: It is a major ingredient in livestock feed production, especially for poultry and piggery.
- Industrial Use: Used in the production of flour, starch, oil, alcohol, and even ethanol fuel.
- Employment and Income: Supports millions of rural households through farming, processing, and marketing activities.
- Export Potential: Nigeria occasionally exports maize to neighboring countries, boosting regional trade.
Suitable Conditions for Maize Farming in Nigeria
Maize thrives under the following conditions:
- Climate: Requires warm weather with temperatures between 21°C and 30°C.
- Rainfall: Optimal rainfall of 600mm to 1,200mm during the growing period.
- Soil Type: Grows best in well-drained loamy or sandy-loam soils with good organic content and a pH range of 5.5 to 7.0.
- Sunlight: Needs full sunlight throughout its growth cycle.
- Topography: Flat or gently sloping land is preferred to prevent erosion.
Planting Season for Maize in Nigeria
The planting season varies depending on the region and rainfall pattern:
- Southern Nigeria: Planting begins from March to April, marking the start of the first rainy season.
- Middle Belt and Northern Nigeria: Planting usually starts from May to June. In regions with short rainy seasons, early maturing varieties are used.
- Dry Season Farming (Irrigation): With access to irrigation, dry season maize is cultivated between November and February, especially in parts of northern Nigeria.
Farmers are advised to begin land preparation before the rains and plant when the soil is moist enough for germination.
Steps in Maize Cultivation in Nigeria
Maize farming involves several steps, which must be followed carefully for successful production:
a. Land Preparation
Clear the land, plough or hoe to loosen the soil, and remove weeds. Beds or ridges may be prepared depending on soil type and region.
b. Seed Selection
Choose high-yielding, disease-resistant hybrid or open-pollinated varieties suitable for the region. Popular varieties in Nigeria include SAMMAZ, Oba Super, and EVDT maize lines.
c. Planting
Plant maize seeds 2 to 5 cm deep. Space plants 25–30 cm apart in rows 75–90 cm apart. Usually, one or two seeds per hole are planted.
d. Fertilization
Apply NPK (15:15:15) fertilizer two weeks after planting and urea (or organic compost) 6 weeks later. Soil testing is advised for proper nutrient balance.
e. Weeding
Weed the farm 2 to 3 times during the crop cycle. Use manual methods or selective herbicides for weed control.
f. Pest and Disease Control
Apply insecticides or use biological controls to manage pests such as armyworms, stem borers, and aphids. Fungal diseases like maize rust and leaf blight should be treated promptly with fungicides.
g. Harvesting
Maize is harvested 90 to 120 days after planting, depending on the variety. Dry maize is harvested when the cobs are dry and the grains are hard and can be threshed easily.
Economic and Nutritional Value of Maize
- Economic Value:
Maize is an affordable source of income and raw material for agro-industries. It drives rural employment and supports poultry and livestock sectors. - Nutritional Value:
Maize contains carbohydrates, dietary fiber, vitamins (especially B-complex), and minerals such as magnesium and phosphorus. Yellow maize also provides beta-carotene, a source of Vitamin A.
Challenges in Maize Production in Nigeria
Despite its importance, maize farming in Nigeria faces several obstacles:
- Unpredictable Rainfall: Climate variability affects planting time and yield.
- Pests and Diseases: Outbreaks like fall armyworm can destroy entire fields.
- High Cost of Inputs: Seeds, fertilizers, and pesticides are expensive.
- Storage Losses: Poor post-harvest practices lead to mold, weevil damage, and aflatoxin contamination.
- Limited Access to Finance: Smallholder farmers lack capital to scale production.
- Poor Market Access: Farmers struggle to access stable markets and fair prices.
Solutions and Best Practices for Maize Cultivation in Nigeria
To improve maize production in Nigeria, the following strategies are recommended:
- Use of Improved Seeds: Adopt early-maturing, drought-tolerant, and pest-resistant varieties.
- Proper Timing: Plant early with the onset of rain to maximize growth period.
- Irrigation Farming: Expand access to dry season maize cultivation using affordable irrigation tools.
- Integrated Pest Management (IPM): Combine cultural, biological, and chemical controls for pest management.
- Storage Facilities: Use airtight bags, silos, or cribs to reduce post-harvest losses.
- Government and NGO Support: Provide subsidized inputs, training, and access to credit facilities.

Conclusion on maize cultivation in Nigeria
Maize cultivation remains one of Nigeria’s most promising agricultural ventures, contributing to both food security and economic growth. With favorable climatic conditions, fertile land, and a large domestic market, Nigeria has the potential to become not only self-sufficient in maize production but also a major exporter in West Africa. However, maximizing this potential depends on addressing critical challenges such as pest management, irrigation, market access, and modern farming practices. With improved policy support and farmer empowerment, maize farming in Nigeria can truly thrive.
