Growing Passion Fruit in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Kwale County is a challenging environment for Passion Fruit (soil-match score 2/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 5.5–7.5 band Passion Fruit prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Passion Fruit, which favours loam. At 200 m, the county sits below Passion Fruit's preferred altitude range (1200–2500 m), which limits yield potential due to heat stress. Passion Fruit's full potential is about 8,000 kg/acre (~KES 560,000/acre at KES 70/kg), but at Kwale's 2/100 suitability a realistic target here is closer to 200 kg/acre (~KES 14,000/acre) unless the constraints above are addressed.
