Growing Eggplant in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Yes, with the right inputs — Vihiga is moderately suited to Eggplant. Vihiga's soil (pH 5.62, slightly acidic) gives Eggplant a suitability score of 59/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Eggplant can be grown in Vihiga County, but the soil scores 59/100 and needs targeted management to reach full potential. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–7 band Eggplant prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Eggplant, which favours loam. On ShambaIQ's soil-match model, Eggplant is the #51 soil match of the 106 crops we assess for Vihiga County. Eggplant's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Vihiga's 59/100 suitability a realistic target here is closer to 7,375 kg/acre (~KES 368,750/acre) unless the constraints above are addressed.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.
