Beans farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow beans in Kenya, aim for soil pH 6–7 (loam soils); the best-suited counties are Uasin Gishu, Nakuru, Elgeyo Marakwet, Kajiado, Nairobi. Apply DAP or NPK at planting and top-dress with None at None required. A well-managed crop yields about 800 kg/acre (~KES 104,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing 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 Beans
Beans does best with 500–1,600 mm of rainfall a year at 0–2,500 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 Beans in Kenya
To achieve maximum yields when farming beans 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. Beans has a low nitrogen requirement, medium phosphorus requirement, and low 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 None at None required), ensures high crop quality and protects your overall farm investment.
How to grow beans 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 beans during Long Rains (Sowing & Basal Fertilizer (DAP)–Flowering Stage & Pest Control) or Short Rains (Sowing & Basal Fertilizer–Flowering Stage) or Dry Season (Post-Harvest Storage–Seed Selection), timed to the start of the rains.
- 3Apply basal fertilizerBeans needs low nitrogen, medium phosphorus, and low potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt None required, apply 0 bag(s) per acre of None. Beans fix their own Nitrogen. Do NOT apply CAN — it will reduce yield.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 800 kg/acre at roughly KES 130/kg.

What fertilizer does beans need?
Beans has low nitrogen, medium phosphorus, and low potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 0 bag(s) per acre of None at None required.
When should I plant beans in Kenya?
Plant beans during Long Rains (Sowing & Basal Fertilizer (DAP) to Flowering Stage & Pest Control) or Short Rains (Sowing & Basal Fertilizer to Flowering Stage) or Dry Season (Post-Harvest Storage to Seed Selection), timed to the start of the rains in your area.
How much can I earn from beans per acre in Kenya?
Beans yields about 800 kg per acre. At a market price of roughly KES 130/kg, that is around KES 104,000 per acre in gross revenue, before input and labour costs.
