Capsicum farming guide — Kenya

Soil requirements, top counties, seed varieties, fertilizer plan & economics

Quick answer

To grow capsicum in Kenya, aim for soil pH 5.57 (loam soils); the best-suited counties are Nakuru, Narok, Baringo, Elgeyo Marakwet, West Pokot. Apply DAP or NPK at planting and top-dress with CAN at Week 3, 6, and 9 after transplanting. A well-managed crop yields about 6,000 kg/acre (~KES 540,000 gross per acre).

Capsicum does best with 6001,200 mm of rainfall a year at 02,000 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 Capsicum in Kenya

To achieve maximum yields when farming capsicum in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.5 to 7. 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. Capsicum has a high nitrogen requirement, high 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 Week 3, 6, and 9 after transplanting), ensures high crop quality and protects your overall farm investment.

How to grow capsicum in Kenya

  1. 1
    Prepare the soil
    Ensure soil pH is between 5.5 and 7. Preferred texture: Loam. Apply agricultural lime if your pH is below 5.5, ideally 30 days before planting.
  2. 2
    Plant at the right time
    Select certified capsicum seed varieties suited to your altitude zone and plant at the onset of the rains.
  3. 3
    Apply basal fertilizer
    Capsicum needs high nitrogen, high phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
  4. 4
    Top-dress
    At Week 3, 6, and 9 after transplanting, apply 0.5 bag(s) per acre of CAN. Split into 3 applications. Add foliar potassium at fruiting stage for fruit size and quality.
  5. 5
    Monitor and harvest
    Scout regularly for pests and disease. Expected yield is about 6,000 kg/acre at roughly KES 90/kg.

Frequently asked questions about capsicum farming in Kenya

What soil pH is best for growing capsicum in Kenya?

Capsicum grows best in soil with a pH of 5.5 to 7. If your soil is more acidic than pH 5.5, apply agricultural lime about 30 days before planting to raise the pH and free up nutrients. The preferred soil texture is loam.

Which counties are best for capsicum farming in Kenya?

By soil suitability, the top counties for capsicum are Nakuru, Narok, Baringo, Elgeyo Marakwet, West Pokot. A full ranking of all 47 counties, each with a suitability score, is shown above.

What fertilizer does capsicum need?

Capsicum has high nitrogen, high phosphorus, and high potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 0.5 bag(s) per acre of CAN at Week 3, 6, and 9 after transplanting.

How much can I earn from capsicum per acre in Kenya?

Capsicum yields about 6,000 kg per acre. At a market price of roughly KES 90/kg, that is around KES 540,000 per acre in gross revenue, before input and labour costs.
