How Many Weeks or Months Before Corn Is Ready for Harvest in Nigeria?
A Simple Guide for Young Farmers
Corn (maize) is one of the fastest-growing crops in Nigeria, and knowing how long it takes to mature helps you plan your planting, weeding, fertilizing, and harvesting properly.
1. How Long Before Corn Is Ready for Harvest?
In Nigeria, corn usually takes between 10 to 14 weeks (that is 2½ to 3½ months) from planting to harvest, depending on the variety and your farming conditions.
Breakdown by Corn Variety:
- Early-maturing varieties:
- Maturity: 8–10 weeks
- Examples: Oba Super series, early hybrid maize
- Best for farmers who want quick harvests
- Medium-maturing varieties:
- Maturity: 10–12 weeks
- Late-maturing varieties:
- Maturity: 12–14+ weeks
- Usually produce bigger yields but take longer
2. Week-by-Week Growth Stages
Understanding these stages helps you know what to expect:
Week 0–1: Germination
- Corn seeds sprout 3–7 days after planting.
- Keep soil moist for good germination.
Week 2–4: Early Vegetative Growth
- Plant grows fast.
- First weeding should be done here.
Week 5–7: Rapid Growth
- Corn height increases sharply.
- Apply fertilizer (NPK or Urea) at knee-height.
Week 8–10: Tasselling & Pollination
- Plant forms tassels (top flowers) and silks (on the cob).
- Proper rainfall is important.
Week 10–14: Grain Filling
- Kernels swell and harden.
- Watch out for pests like stem borers and armyworms.
Week 12–14+: Harvest Time
- For fresh/green corn: harvest at 10–12 weeks.
- For dry maize grain: harvest at 12–14+ weeks when cobs are fully dry.
3. How to Know When Corn Is Ready for Harvest
For Fresh (Green) Corn
- Silks turn brown.
- Kernels are filled with milky juice.
- Usually between 70–85 days.
For Dry Grain
- The husk becomes dry and brown.
- Cobs feel hard and dry.
- Kernels no longer produce milk when pressed.
- Usually 90–110 days.
4. Important Tips for Young Farmers
- Plant at the start of the rains for best results (April–June for major season).
- Use good seed varieties from certified agro-shops.
- Weed early so weeds don’t compete with your corn.
- Apply fertilizer at the right time (2–4 weeks after planting).
- Avoid waterlogging—maize hates standing water.
- Harvest early if you want fresh corn for boiling or roasting.
- Dry properly if you want to store as grain.

| Type of Corn | Time Before Harvest |
