Growing African Nightshade in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Yes, with the right inputs — Nyamira is moderately suited to African Nightshade. Nyamira's soil (pH 5.58, slightly acidic) gives African Nightshade a suitability score of 71/100. Match fertilizer to Nyamira's nitrogen and phosphorus levels for the best result.
Nyamira County is a solid choice for African Nightshade, with a soil-match score of 71/100. Local soils average pH 5.58 — 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 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit African Nightshade, which favours loam. On ShambaIQ's soil-match model, African Nightshade is the #29 soil match of the 106 crops we assess for Nyamira County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Nyamira's 71/100 suitability a realistic target here is closer to 4,438 kg/acre (~KES 221,900/acre) unless the constraints above are addressed.
