Growing Passion Fruit in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Passion Fruit. Wajir's soil (pH 8.4, alkaline) gives Passion Fruit a suitability score of 0/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir 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 8.4 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 0.52 g/kg, P 39.3 mg/kg, K 396 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 Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 mm/year — well below Passion Fruit's minimum of 900 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Passion Fruit is the #90 soil match of the 106 crops we assess for Wajir County. Passion Fruit's full potential is about 8,000 kg/acre (~KES 560,000/acre at KES 70/kg), but at Wajir's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Wajir's nitrogen (0.52 g/kg) is 43% of the 1.2 g/kg Passion Fruit needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
