Growing Passion Fruit in Machakos
Soil suitability analysis based on Machakos's nutrient profile
Possible but challenging — Machakos is only marginally suited to Passion Fruit. Machakos's soil (pH 7.03, near-neutral) gives Passion Fruit a suitability score of 41/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.
Machakos County is a challenging environment for Passion Fruit (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band Passion Fruit prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.82 g/kg, P 31.4 mg/kg, K 338 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Passion Fruit, which favours loam. On ShambaIQ's soil-match model, Passion Fruit is the #81 soil match of the 106 crops we assess for Machakos County. Passion Fruit's full potential is about 8,000 kg/acre (~KES 560,000/acre at KES 70/kg), but at Machakos's 41/100 suitability a realistic target here is closer to 4,100 kg/acre (~KES 287,000/acre) unless the constraints above are addressed.
Better matched to Machakos's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.
