Growing African Nightshade in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Taita Taveta County is a challenging environment for African Nightshade (soil-match score 16/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 5.5–7.5 band African Nightshade prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit African Nightshade, which favours loam. Taita Taveta receives approximately 500 mm/year — well below African Nightshade's minimum of 800 mm — so supplemental irrigation would be essential for this crop. 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.
