Growing Cowpeas in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Possible but challenging — Kisumu is only marginally suited to Cowpeas. Kisumu's soil (pH 5.54, slightly acidic) gives Cowpeas a suitability score of 51/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.
Cowpeas can be grown in Kisumu County, but the soil scores 51/100 and needs targeted management to reach full potential. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5–8 band Cowpeas prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Cowpeas's requirements, so a maintenance fertilizer programme is enough. Cowpeas prefers sandy soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cowpeas is the #83 soil match of the 106 crops we assess for Kisumu County. Cowpeas's full potential is about 450 kg/acre (~KES 29,250/acre at KES 65/kg), but at Kisumu's 51/100 suitability a realistic target here is closer to 287 kg/acre (~KES 18,655/acre) unless the constraints above are addressed.
Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Kisumu's nitrogen reads 0.91 g/kg, but the rate stays at zero: Cowpeas is not top-dressed, for the crop-specific reason above.
