Growing Tree Tomato (Tamarillo) in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Vihiga County is well suited to Tree Tomato (Tamarillo), scoring 75/100 on ShambaIQ's soil-match model. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Tree Tomato (Tamarillo)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. 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 Tree Tomato (Tamarillo), which favours loam. At current prices (about KES 80/kg) and a typical 8,000 kg/acre yield, a well-managed Tree Tomato (Tamarillo) crop here can gross roughly KES 640,000 per acre.
