Growing African Nightshade in Bungoma

Soil suitability analysis based on Bungoma's nutrient profile

Quick answer

Yes — Bungoma is well suited to African Nightshade. Bungoma's soil (pH 5.56, slightly acidic) gives African Nightshade a suitability score of 78/100. Match fertilizer to Bungoma's nitrogen and phosphorus levels for the best result.

Bungoma County is well suited to African Nightshade, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 5.56 — 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 — measured at N 1.12 g/kg, P 15.7 mg/kg, K 161 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit African Nightshade, which favours loam. On ShambaIQ's soil-match model, African Nightshade is the #35 soil match of the 106 crops we assess for Bungoma County. At current prices (about KES 50/kg) and a typical 5,000 kg/acre yield, a well-managed African Nightshade crop here can gross roughly KES 250,000 per acre.
