Growing African Nightshade in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Bomet County is well suited to African Nightshade, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 5.5–7.5 band African Nightshade prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet African Nightshade's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit African Nightshade, which favours loam. At current prices (about KES 50/kg) and a typical 3,500 kg/acre yield, a well-managed African Nightshade crop here can gross roughly KES 175,000 per acre.
