African Nightshade farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow african nightshade in Kenya, aim for soil pH 5.5–7.5 (loam soils); the best-suited counties are Nakuru, Uasin Gishu, Elgeyo Marakwet, Narok, Nandi. Apply DAP or NPK at planting and top-dress with CAN at Week 2-3 after transplanting. A well-managed crop yields about 5,000 kg/acre (~KES 250,000 gross per acre).
Interested in starting or scaling african nightshade farming in Kenya? This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing african nightshade, 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 African Nightshade
African Nightshade does best with 800–1,500 mm of rainfall a year at 1,000–2,200 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 African Nightshade in Kenya
To achieve maximum yields when farming african nightshade in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.5 to 7.5. 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. African Nightshade has a high nitrogen requirement, medium 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 transplanting), ensures high crop quality and protects your overall farm investment.
How to grow african nightshade in Kenya
- 1Prepare the soilEnsure soil pH is between 5.5 and 7.5. Preferred texture: Loam. Apply agricultural lime if your pH is below 5.5, ideally 30 days before planting.
- 2Plant at the right timePlant african nightshade during Long Rains (Transplanting & Basal Fertilizer (DAP)–Continuous Leaf Harvest) or Short Rains (Transplanting & Basal Fertilizer–Harvesting & Market) or Dry Season (Irrigation & Continuous Harvesting–Replanting if stand is old), timed to the start of the rains.
- 3Apply basal fertilizerAfrican Nightshade needs high nitrogen, medium phosphorus, and medium potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 2-3 after transplanting, apply 1 bag(s) per acre of CAN. Top dress 2-3 weeks after transplanting and after each picking to push tender leaf regrowth
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 5,000 kg/acre at roughly KES 50/kg.

Which counties are best for african nightshade farming in Kenya?
By soil suitability, the top counties for african nightshade are Nakuru, Uasin Gishu, Elgeyo Marakwet, Narok, Nandi. A full ranking of all 47 counties, each with a suitability score, is shown above.
What fertilizer does african nightshade need?
African Nightshade has high nitrogen, medium phosphorus, and medium potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 1 bag(s) per acre of CAN at Week 2-3 after transplanting.
When should I plant african nightshade in Kenya?
Plant african nightshade during Long Rains (Transplanting & Basal Fertilizer (DAP) to Continuous Leaf Harvest) or Short Rains (Transplanting & Basal Fertilizer to Harvesting & Market) or Dry Season (Irrigation & Continuous Harvesting to Replanting if stand is old), timed to the start of the rains in your area.
How much can I earn from african nightshade per acre in Kenya?
African Nightshade yields about 5,000 kg per acre. At a market price of roughly KES 50/kg, that is around KES 250,000 per acre in gross revenue, before input and labour costs.
