Tomato farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow tomato in Kenya, aim for soil pH 6–7 (loam soils); the best-suited counties are Nakuru, Elgeyo Marakwet, Narok, Baringo, West Pokot. Apply DAP or NPK at planting and top-dress with CAN at Week 3, 6, and 9. A well-managed crop yields about 15,000 kg/acre (~KES 750,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing tomato, certified seed varieties, seasonal fertilizer guidelines, and a detailed per-acre production budget to set you up for a successful harvest.
Soil requirements
Growing conditions for Tomato
Tomato does best with 600–1,400 mm of rainfall a year at 0–1,800 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 Tomato in Kenya
To achieve maximum yields when farming tomato in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 6 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. Tomato 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), ensures high crop quality and protects your overall farm investment.
How to grow tomato in Kenya
- 1Prepare the soilEnsure soil pH is between 6 and 7. Preferred texture: Loam. Apply agricultural lime if your pH is below 6, ideally 30 days before planting.
- 2Plant at the right timePlant tomato during Long Rains (Nursery Preparation & Transplanting–Harvesting & Disease Management) or Short Rains (Nursery & Transplanting & Basal Fertilizer–Harvesting) or Dry Season (Land Preparation & Irrigation Setup–Transplanting & Basal Fertilizer), timed to the start of the rains.
- 3Apply basal fertilizerTomato needs high nitrogen, high phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 3, 6, and 9, apply 0.5 bag(s) per acre of CAN. Split into 3 applications. Add foliar potassium at fruiting stage.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 15,000 kg/acre at roughly KES 50/kg.

Frequently asked questions about tomato farming in Kenya
What soil pH is best for growing tomato in Kenya?
Tomato grows best in soil with a pH of 6 to 7. If your soil is more acidic than pH 6, 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 tomato farming in Kenya?
By soil suitability, the top counties for tomato are Nakuru, Elgeyo Marakwet, Narok, Baringo, West Pokot. A full ranking of all 47 counties, each with a suitability score, is shown above.
What fertilizer does tomato need?
Tomato 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.
When should I plant tomato in Kenya?
Plant tomato during Long Rains (Nursery Preparation & Transplanting to Harvesting & Disease Management) or Short Rains (Nursery & Transplanting & Basal Fertilizer to Harvesting) or Dry Season (Land Preparation & Irrigation Setup to Transplanting & Basal Fertilizer), timed to the start of the rains in your area.
How much can I earn from tomato per acre in Kenya?
Tomato yields about 15,000 kg per acre. At a market price of roughly KES 50/kg, that is around KES 750,000 per acre in gross revenue, before input and labour costs.
