Growing Eggplant in Uasin Gishu

Soil suitability analysis based on Uasin Gishu's nutrient profile

Quick answer

Yes, with the right inputs — Uasin Gishu is moderately suited to Eggplant. Uasin Gishu's soil (pH 6.39, slightly acidic) gives Eggplant a suitability score of 68/100. Match fertilizer to Uasin Gishu's nitrogen and phosphorus levels for the best result.

Uasin Gishu County is a solid choice for Eggplant, with a soil-match score of 68/100. Local soils average pH 6.39 — slightly acidic to near-neutral and inside the 5.5–7 band Eggplant prefers, so no lime is usually required. Nitrogen (1.56 g/kg), phosphorus (25.3 mg/kg) and potassium (227 mg/kg) all meet Eggplant's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Eggplant, which favours loam. On ShambaIQ's soil-match model, Eggplant is the #69 soil match of the 106 crops we assess for Uasin Gishu County. Eggplant's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Uasin Gishu's 68/100 suitability a realistic target here is closer to 8,500 kg/acre (~KES 425,000/acre) unless the constraints above are addressed.
