Growing Bambara Nuts in Kakamega
Soil suitability analysis based on Kakamega's nutrient profile
Possible but challenging — Kakamega is only marginally suited to Bambara Nuts. Kakamega's soil (pH 5.63, slightly acidic) gives Bambara Nuts a suitability score of 47/100. Match fertilizer to Kakamega's nitrogen and phosphorus levels for the best result.
Bambara Nuts can be grown in Kakamega County, but the soil scores 47/100 and needs targeted management to reach full potential. Local soils average pH 5.63 — slightly acidic to near-neutral and inside the 5–6.5 band Bambara Nuts prefers, so no lime is usually required. Nitrogen (1.01 g/kg), phosphorus (14 mg/kg) and potassium (147 mg/kg) all meet Bambara Nuts's requirements, so a maintenance fertilizer programme is enough. Bambara Nuts prefers sandy soils, while Kakamega is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Bambara Nuts is the #68 soil match of the 106 crops we assess for Kakamega County. Bambara Nuts's full potential is about 400 kg/acre (~KES 60,000/acre at KES 150/kg), but at Kakamega's 47/100 suitability a realistic target here is closer to 235 kg/acre (~KES 35,250/acre) unless the constraints above are addressed.
Better matched to Kakamega's soil: Soybeans, Rice (Lowland/Paddy), and Sweet Potato — each scores higher on the same soil.
