Growing African Nightshade in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a solid choice for African Nightshade, with a soil-match score of 70/100. At an average pH of 5.23 the soil is moderately acidic, below African Nightshade's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. African Nightshade prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, African Nightshade is the #42 soil match of the 106 crops we assess for Nyeri County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Nyeri's 70/100 suitability a realistic target here is closer to 4,375 kg/acre (~KES 218,750/acre) unless the constraints above are addressed.
