Growing Passion Fruit in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Passion Fruit (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Passion Fruit's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Passion Fruit prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Passion Fruit's minimum of 900 mm — so supplemental irrigation would be essential for this crop. Passion Fruit's full potential is about 8,000 kg/acre (~KES 560,000/acre at KES 70/kg), but at Mandera's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
