The country’s climate and soil conditions make it an ideal location for walnut farming.

This guide provides a step-by-step approach to walnut farming in Nigeria, including insights on planting, maintenance, harvesting, and market visibility to maximize income.

Step-by-Step Guide to Walnut Farming in Nigeria

1. Choosing the Right Walnut Variety

Walnuts come in several varieties, each suited to specific climates and soil types. The most common varieties suitable for Nigeria include:

• African Walnut (Tetracarpidium conophorum) – Native to West Africa, widely cultivated in Nigeria for its medicinal and nutritional properties.
• English Walnut (Juglans regia) – Though not native to Nigeria, it can be grown in cooler regions with proper care.
• Black Walnut (Juglans nigra) – Used mainly for timber and specialty products, but requires deep and fertile soils for optimal growth.

2. Selecting the Ideal Location

Walnut trees thrive in well-drained, deep loamy soil with a pH level between 6.0 and 7.5. The ideal climate should have distinct dry and wet seasons, with moderate temperatures for proper tree development. Suitable states for walnut farming in Nigeria include:

• Ogun State
• Ondo State
• Edo State
• Cross River State
• Benue State

3. Land Preparation and Planting

• Soil Preparation: Conduct soil testing to determine nutrient levels and pH adjustments.
• Spacing: Trees should be planted 40-50 feet apart to allow proper canopy development.
• Planting: Best done in late rainy season or early dry season when the soil is moist but not waterlogged.
• Propagation Methods: Walnut trees can be propagated through seeds or grafting, with grafted varieties yielding faster results.

4. Irrigation and Fertilization

• Watering: Young trees require consistent watering, especially in dry conditions. Drip irrigation is highly recommended for commercial walnut farming in Nigeria.
• Fertilization: Apply balanced fertilizers with nitrogen, phosphorus, and potassium to promote growth. Organic compost and manure can also be used to enrich the soil.

5. Pruning and Disease Management

• Pruning: Necessary in the early years to shape the tree and encourage strong branch structure.
• Common Diseases: Watch out for walnut blight, root rot, and anthracnose. Use organic or chemical treatments accordingly.
• Pest Control: Protect trees from rodents and insects like walnut husk flies using organic pesticides and good farm hygiene practices.

6. Harvesting and Post-Harvest Processing

• Harvesting: Walnuts are ready for harvest when the outer husk splits and falls off naturally. In Nigeria, the best harvest period is between August and November.
• Drying: Proper drying is essential to prevent mold and preserve quality. Sun drying is common, but using mechanical dryers can improve efficiency.
• Storage: Store in cool, dry conditions or refrigerate for extended shelf life. Proper packaging ensures better market value.
