Growing Pumpkin in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Homa Bay County is a solid choice for Pumpkin, with a soil-match score of 67/100. At an average pH of 5.27 the soil is moderately acidic, below Pumpkin's preferred 5.8–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.05 g/kg, P 13.8 mg/kg, K 147 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Pumpkin prefers sandy loam soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. Pumpkin's full potential is about 10,000 kg/acre (~KES 300,000/acre at KES 30/kg), but at Homa Bay's 67/100 suitability a realistic target here is closer to 8,375 kg/acre (~KES 251,250/acre) unless the constraints above are addressed.
