Cassava Farming in Nigeria: A Practical Season Guide

14 July 2026 · 8 min read · AgroForth agronomy team

Cassava is the most forgiving staple most Nigerian farmers can plant, which is exactly why margins are so often thin — everyone can grow it, so the money sits in variety choice, weed control and what you do with the roots after harvest.

Choose the variety for your end market, not the yield table

Improved varieties released through IITA and NRCRI breeding programmes differ mainly in starch content, maturity window and disease tolerance. High-starch types suit garri and industrial starch buyers; lower-dry-matter types are easier to sell fresh into urban markets.

Decide the buyer first. If a processor within 40 km takes roots at a fixed price, match the variety they pay a premium for. If you are selling fresh into a town market, earliness matters more than starch.

Land preparation and spacing

On ridges, 1 m × 1 m spacing gives roughly 10,000 stands per hectare and remains the practical default for most rain-fed plots. Tighter spacing raises stand count but reduces individual root size, which hurts you if the buyer pays per big root rather than per tonne.

Plant cuttings of 20–25 cm at a slant with two-thirds buried, at the start of steady rains. Late planting into a shortening rainy season is the single most common cause of disappointing first-year yields.

The first 12 weeks decide the harvest

Cassava competes poorly with weeds early. Two to three clean weedings in the first three months typically make a bigger difference than any fertiliser decision. After canopy closure, the crop largely defends itself.

Watch for cassava mosaic and bacterial blight symptoms in the first weeks; rogue out badly affected stands rather than trying to treat them.

Harvest timing and the processing decision

Most improved varieties reach harvest between 9 and 12 months. Roots deteriorate within 48–72 hours of lifting, so harvest only what can be moved or processed immediately.

Processing into garri, fufu flour, or high-quality cassava flour usually adds more value per hectare than selling fresh roots — but it needs a reliable grater, press and drying space. Cost the equipment against a full season before committing.

Frequently asked

How many cassava stems do I need per hectare?

At the standard 1 m × 1 m spacing you need roughly 10,000 cuttings per hectare, plus about 10% extra to replace failures.

When should I harvest cassava?

Most improved varieties are ready between 9 and 12 months after planting. Lift only what you can process or sell within two to three days.
