Growing Cowpeas in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Bomet County is a challenging environment for Cowpeas (soil-match score 40/100) and will need significant amendment before planting. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 5–8 band Cowpeas prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 mg/kg) all meet Cowpeas's requirements, so a maintenance fertilizer programme is enough. Cowpeas prefers sandy soils, while Bomet is largely clay loam, so drainage and organic-matter management matter more here. Cowpeas's full potential is about 450 kg/acre (~KES 29,250/acre at KES 65/kg), but at Bomet's 40/100 suitability a realistic target here is closer to 225 kg/acre (~KES 14,625/acre) unless the constraints above are addressed.
