Growing Pawpaw in Nakuru

Soil suitability analysis based on Nakuru's nutrient profile

Nakuru County is a challenging environment for Pawpaw (soil-match score 42/100) and will need significant amendment before planting. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 6–7.5 band Pawpaw prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 mg/kg) all meet Pawpaw's requirements, so a maintenance fertilizer programme is enough. Pawpaw prefers sandy loam soils, while Nakuru is largely clay loam, so drainage and organic-matter management matter more here. At 1750 m, the county sits above Pawpaw's preferred altitude ceiling of 1200 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Pawpaw is the #100 soil match of the 106 crops we assess for Nakuru County. Pawpaw's full potential is about 12,000 kg/acre (~KES 336,000/acre at KES 28/kg), but at Nakuru's 42/100 suitability a realistic target here is closer to 6,300 kg/acre (~KES 176,400/acre) unless the constraints above are addressed.

Better matched to Nakuru's soil: Carrot, Dolichos, and Garden Peas — each scores higher on the same soil.
