Growing African Nightshade in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Kilifi County is a challenging environment for African Nightshade (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–7.5 band African Nightshade prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit African Nightshade, which favours loam. At 150 m, the county sits below African Nightshade's preferred altitude range (1000–2200 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, African Nightshade is the #89 soil match of the 106 crops we assess for Kilifi County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Kilifi's 1/100 suitability a realistic target here is closer to 63 kg/acre (~KES 3,150/acre) unless the constraints above are addressed.

Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.
