Growing Passion Fruit in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Passion Fruit (soil-match score 14/100) 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 0.74 g/kg, P 30.5 mg/kg, K 339 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. Kitui receives approximately 500 mm/year — well below Passion Fruit's minimum of 900 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 70/kg) and a typical 4,500 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 315,000 per acre.
