Coffee
Coffea arabica / C. canephora
About Coffee
Coffee is the world's most traded tropical agricultural commodity and supports the livelihoods of over 125 million people worldwide. Two species dominate: Arabica (C. arabica, 60% of production, highland, superior flavor) and Robusta (C. canephora, 40%, lowland, higher caffeine, disease resistant). Brazil is the world's largest producer, followed by Vietnam, Colombia, Indonesia, and Ethiopia. In Africa, coffee is a critical export earner for Ethiopia, Uganda, Kenya, Tanzania, and Rwanda. The crop is shade-tolerant and traditionally grown under forest canopy or planted shade trees. Climate change is reducing suitable Arabica growing area, while coffee leaf rust epidemics have devastated production in Central America and Africa.
Growing Conditions
Partial shade to full sun — Arabica prefers 40-60% shade, Robusta tolerates full sun
1,500-2,500 mm annually for Arabica, evenly distributed. Distinct dry period (2-3 months) triggers synchronized flowering.
Deep, well-drained, volcanic or forest soil. pH 5.0-6.5. Rich in organic matter. Arabica prefers acidic soils.
Arabica: 15-24°C (highland). Robusta: 22-30°C (lowland). Frost kills both species.
Moderate to high. Very high humidity promotes coffee leaf rust and coffee berry disease.
Perennial — first harvest 3-4 years after planting. Main harvest annually, with some regions having a secondary (fly) crop.
Step-by-Step Growing Tips
Maintain shade trees (Grevillea, Inga, Erythrina) at 40-60% canopy cover for Arabica
Apply organic mulch (4-6 cm) around plants — coffee has shallow roots
Prune to maintain open bush structure — coffee bears on 1-year-old wood
Apply balanced NPK + micronutrients (Zn, B) annually after harvest
Pick only ripe (red) cherries for highest quality — avoid strip picking
Process cherries within 24 hours of picking (washed method) for premium quality
