Growing Pumpkin in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Yes, with the right inputs — Kisii is moderately suited to Pumpkin. Kisii's soil (pH 5.21, strongly acidic) gives Pumpkin a suitability score of 58/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Pumpkin can be grown in Kisii County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.21 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 1.09 g/kg, P 13.1 mg/kg, K 151 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 Kisii is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Pumpkin is the #55 soil match of the 106 crops we assess for Kisii County. Pumpkin's full potential is about 10,000 kg/acre (~KES 300,000/acre at KES 30/kg), but at Kisii's 58/100 suitability a realistic target here is closer to 7,250 kg/acre (~KES 217,500/acre) unless the constraints above are addressed.
Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
