Growing Tree Tomato (Tamarillo) in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

Murang'a County is a solid choice for Tree Tomato (Tamarillo), with a soil-match score of 61/100. At an average pH of 5.03 the soil is moderately acidic, 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 phosphorus and potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tree Tomato (Tamarillo) prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Tree Tomato (Tamarillo) is the #58 soil match of the 106 crops we assess for Murang'a County. Tree Tomato (Tamarillo)'s full potential is about 8,000 kg/acre (~KES 640,000/acre at KES 80/kg), but at Murang'a's 61/100 suitability a realistic target here is closer to 6,100 kg/acre (~KES 488,000/acre) unless the constraints above are addressed.
