French Beans farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow french beans in Kenya, aim for soil pH 5.8–7 (loam soils); the best-suited counties are Uasin Gishu, Nakuru, Elgeyo Marakwet, Nandi, West Pokot. Apply DAP or NPK at planting and top-dress with CAN at Week 2-3 after emergence. A well-managed crop yields about 3,500 kg/acre (~KES 280,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing french beans, 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 French Beans
French Beans does best with 900–1,500 mm of rainfall a year at 1,000–2,100 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 French Beans in Kenya
To achieve maximum yields when farming french beans in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.8 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. French Beans has a low nitrogen requirement, high phosphorus requirement, and medium 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 2-3 after emergence), ensures high crop quality and protects your overall farm investment.
How to grow french beans in Kenya
- 1Prepare the soilEnsure soil pH is between 5.8 and 7. Preferred texture: Loam. Apply agricultural lime if your pH is below 5.8, ideally 30 days before planting.
- 2Plant at the right timePlant french beans during Long Rains (Sowing & DAP Basal Fertilizer (at planting)–Pod Fill & Harvesting starts) or Short Rains (Sowing & Basal Fertilizer–Harvesting & Grading for export) or Dry Season (Harvesting remaining pods & Land Preparation–Seed multiplication & storage), timed to the start of the rains.
- 3Apply basal fertilizerFrench Beans needs low nitrogen, high phosphorus, and medium potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 2-3 after emergence, apply 1 bag(s) per acre of CAN. Apply when seedlings have 2-3 true leaves, then a second light dose at flowering for pod fill
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 3,500 kg/acre at roughly KES 80/kg.
