Why Grow Cashew in Nigeria?
Cashew is one of Nigeria's most important agricultural export commodities. Nigeria consistently ranks among Africa's largest cashew producers, and demand for Nigerian cashew — both raw and processed — continues to grow on international markets.
For smallholder farmers, cashew offers several attractive qualities: it is a relatively hardy tree, it produces fruit and nuts annually for decades once established, and it requires less intensive management than many other crops once mature.
Key fact: A well-maintained cashew tree can produce for 20–30 years. The upfront investment in planting and early care pays dividends over a very long productive life.
Climate and Soil Requirements
Cashew trees (Anacardium occidentale) thrive in tropical climates with distinct wet and dry seasons. Nigeria's North-Central and South-West regions provide near-ideal conditions.
Climate Needs
- Temperature: 24–28°C average is ideal. Cashew tolerates heat well but is sensitive to frost (not typically a concern in Nigeria)
- Rainfall: 1,000–2,000mm annually, with a pronounced dry season during flowering and nut development
- Altitude: Below 1,000m above sea level is best — most of Nigeria's cashew belt falls well within this range
- Dry season: A clear dry period of 3–5 months is important — it coincides with the critical flowering and fruiting stage
Soil Requirements
- Well-drained, deep soils — cashew does not tolerate waterlogging
- Sandy loam to lateritic soils are ideal
- Slightly acidic to neutral pH (5.0–6.5)
- Avoid heavy clay soils or areas with high water tables
Key Cashew Producing States in Nigeria
Nigeria's cashew belt runs across several states, each with somewhat different conditions. The main producing states include Kogi, Oyo, Enugu, Kwara, Niger, Anambra, Cross River and Ondo. Kogi State is often cited as one of Nigeria's largest cashew producers, with significant production across its local government areas.
Planting Cashew
Varieties
Nigeria cultivates a mix of local and improved cashew varieties. Improved dwarf varieties tend to start producing earlier (3–4 years vs 7–8 years for tall varieties) and often have higher nut yields. Seek advice from your state's Agricultural Development Programme (ADP) on which varieties perform best in your specific area.
Spacing
Standard spacing for cashew in Nigeria is typically 8m × 8m (156 trees per hectare) or 10m × 10m (100 trees per hectare) for taller varieties. Proper spacing allows each tree enough light and nutrients to produce well and makes harvest easier.
Planting Time
Plant at the beginning of the rainy season so young trees have time to establish before facing their first dry season. In most of Nigeria's cashew belt, this means planting between April and June.
Planting Method
- Prepare planting holes (60cm × 60cm × 60cm) before planting
- Mix the topsoil with compost or well-decomposed organic matter
- Plant cashew seeds (2–3 per hole) directly or transplant nursery-raised seedlings
- If planting seeds, thin to the strongest seedling after 4–6 weeks
- Mulch around young plants to retain moisture
Caring for Cashew Trees
Weeding
Young cashew trees (first 2–3 years) need regular weeding to reduce competition for water and nutrients. As trees mature and canopy closes, weeding becomes less critical.
Pruning
Remove dead branches, crossed branches and water shoots. Light annual pruning after harvest helps shape the tree and improves light penetration, leading to better fruit set the following season.
Fertilisation
In nutrient-poor soils, applying NPK fertiliser during the early growing years (years 1–3) improves establishment. In mature orchards, consider organic matter addition through mulching with cashew shells or other organic material.
Pest and Disease Management
Key pests affecting Nigerian cashew include thrips (which damage flowers and young nuts), stem and root borers, and powdery mildew. Monitor trees regularly — especially during flowering — and consult your local agricultural extension officer for appropriate management approaches.
Harvest
Cashew season in Nigeria typically runs from February to May, peaking in March–April across most producing areas. Trees begin flowering in December–January, with nuts maturing 2–3 months later.
Harvesting Method
The most common harvest method in Nigeria is natural drop — allowing ripe cashew apples (with nuts attached) to fall from the tree naturally and collecting them from the ground daily. This is gentler on the nuts than knocking or pulling.
Post-Harvest Handling
After harvest, separate the cashew nut from the apple quickly (within hours of collection). Sun-dry the raw cashew nuts for 2–3 days to reduce moisture content to 8–10%. Proper drying is critical — high-moisture nuts spoil quickly and attract mould. Store dried nuts in clean, dry sacks in a well-ventilated store.

Join Our Farmer Network →Selling Your Cashew
Most Nigerian cashew farmers currently sell to middlemen (local aggregators) who then sell to larger buyers or exporters. While convenient, this route typically returns only a fraction of the final market price to the farmer.
Alternatives worth exploring include: selling directly to certified processors and exporters (who may pay better prices for quality-graded nuts), forming or joining farmer cooperatives (which give better bargaining power), and accessing market price information before selling so you know whether the offered price is fair.
