Growing Tree Tomato (Tamarillo) in Kisumu
Soil suitability analysis based on Kisumu's nutrient profile
Possible but challenging — Kisumu is only marginally suited to Tree Tomato (Tamarillo). Kisumu's soil (pH 5.54, slightly acidic) gives Tree Tomato (Tamarillo) a suitability score of 41/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.
Kisumu County is a challenging environment for Tree Tomato (Tamarillo) (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 5.54 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 0.91 g/kg, P 12.5 mg/kg, K 166 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 Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Tree Tomato (Tamarillo) is the #96 soil match of the 106 crops we assess for Kisumu County. Tree Tomato (Tamarillo)'s full potential is about 8,000 kg/acre (~KES 640,000/acre at KES 80/kg), but at Kisumu's 41/100 suitability a realistic target here is closer to 4,100 kg/acre (~KES 328,000/acre) unless the constraints above are addressed.
Better matched to Kisumu's soil: Cassava, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Kisumu's nitrogen (0.91 g/kg) is 76% of the 1.2 g/kg Tree Tomato (Tamarillo) needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
