Growing Green Grams in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Possible but challenging — Kisumu is only marginally suited to Green Grams. Kisumu's soil (pH 5.54, slightly acidic) gives Green Grams a suitability score of 48/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.
Green Grams can be grown in Kisumu County, but the soil scores 48/100 and needs targeted management to reach full potential. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (0.91 g/kg), phosphorus (12.5 mg/kg) and potassium (166 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. Green Grams prefers sandy loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. Green Grams's full potential is about 400 kg/acre (~KES 48,000/acre at KES 120/kg), but at Kisumu's 48/100 suitability a realistic target here is closer to 240 kg/acre (~KES 28,800/acre) unless the constraints above are addressed.
