Growing Pumpkin in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Quick answer

Yes — Trans Nzoia is well suited to Pumpkin. Trans Nzoia's soil (pH 5.93, slightly acidic) gives Pumpkin a suitability score of 85/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.

Trans Nzoia County is well suited to Pumpkin, scoring 85/100 on ShambaIQ's soil-match model. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.8–7.5 band Pumpkin prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Pumpkin's requirements, so a maintenance fertilizer programme is enough. Pumpkin prefers sandy loam soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Pumpkin is the #38 soil match of the 106 crops we assess for Trans Nzoia County. 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.
