Growing Passion Fruit in Samburu
Soil suitability analysis based on Samburu's nutrient profile
Generally not ideal — Samburu is poorly suited to Passion Fruit. Samburu's soil (pH 8.28, alkaline) gives Passion Fruit a suitability score of 4/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.
Samburu County is a challenging environment for Passion Fruit (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 8.28 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 0.67 g/kg, P 42.1 mg/kg, K 387 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 Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 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 #94 soil match of the 106 crops we assess for Samburu County. Passion Fruit's full potential is about 8,000 kg/acre (~KES 560,000/acre at KES 70/kg), but at Samburu's 4/100 suitability a realistic target here is closer to 400 kg/acre (~KES 28,000/acre) unless the constraints above are addressed.
Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Samburu's nitrogen (0.67 g/kg) is 56% 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.
