Growing Pumpkin in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Pumpkin can be grown in Tana River County, but the soil scores 53/100 and needs targeted management to reach full potential. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.8–7.5 band Pumpkin prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Pumpkin, which favours sandy loam. Pumpkin's full potential is about 10,000 kg/acre (~KES 300,000/acre at KES 30/kg), but at Tana River's 53/100 suitability a realistic target here is closer to 6,625 kg/acre (~KES 198,750/acre) unless the constraints above are addressed.
