Growing Pumpkin in Nandi

Soil suitability analysis based on Nandi's nutrient profile

Nandi County is well suited to Pumpkin, scoring 82/100 on ShambaIQ's soil-match model. Local soils average pH 6.17 — slightly acidic to near-neutral and inside the 5.8–7.5 band Pumpkin prefers, so no lime is usually required. Nitrogen (1.37 g/kg), phosphorus (26.4 mg/kg) and potassium (207 mg/kg) all meet Pumpkin's requirements, so a maintenance fertilizer programme is enough. Pumpkin prefers sandy loam soils, while Nandi is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 30/kg) and a typical 10,000 kg/acre yield, a well-managed Pumpkin crop here can gross roughly KES 300,000 per acre.
