Coffee (Robusta) farming guide — Kenya

Soil requirements

Growing conditions for Coffee (Robusta)

Coffee (Robusta) does best with 1,500–2,500 mm of rainfall a year at 0–1,200 m above sea level. In drier areas, irrigation or water harvesting closes the gap; outside the altitude band, growth and yields drop.

Optimizing soil and fertilizers for Coffee (Robusta) in Kenya

To achieve maximum yields when farming coffee (robusta) in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5 to 6.5. Soils that fall outside this range can lock out essential macro and micro-nutrients, leading to stunted growth or crop failure. For acidic soils, applying dolomitic or calcitic agricultural lime is recommended at least 30 days before planting to normalize acidity.

Fertilizer application should be calibrated based on the crop’s nutrient demands. Coffee (Robusta) has a high nitrogen requirement, medium phosphorus requirement, and high potassium demand. Using certified seed varieties suited for your specific altitude and rainfall pattern, combined with a precise basal and top-dressing program (such as applying CAN at Split 3 times per year), ensures high crop quality and protects your overall farm investment.

How to grow coffee (robusta) in Kenya

1. 1
   Prepare the soil

   Ensure soil pH is between 5 and 6.5. Preferred texture: Loam. Apply agricultural lime if your pH is below 5, ideally 30 days before planting.
2. 2
   Plant at the right time

   Plant coffee (robusta) during Long Rains (Fertilizer Application & Weed Control–Light Pruning & Pest Management) or Short Rains (Cherry Ripening & Selective Harvesting–Pruning & Stumping if needed) or Dry Season (Main Pruning & Soil Conservation–Pre-Season Fertilizer & Soil pH Check), timed to the start of the rains.
3. 3
   Apply basal fertilizer

   Coffee (Robusta) needs high nitrogen, medium phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
4. 4
   Top-dress

   At Split 3 times per year, apply 1 bag(s) per acre of CAN. Apply after harvest, at flowering, and during berry expansion.
5. 5
   Monitor and harvest

   Scout regularly for pests and disease. Expected yield is about 950 kg/acre at roughly KES 80/kg.
