Growing Passion Fruit in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Quick answer

Yes — Vihiga is well suited to Passion Fruit. Vihiga's soil (pH 5.62, slightly acidic) gives Passion Fruit a suitability score of 77/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.

Vihiga County is well suited to Passion Fruit, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–7.5 band Passion Fruit prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Passion Fruit, which favours loam. At current prices (about KES 70/kg) and a typical 8,000 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 560,000 per acre.
