Growing Passion Fruit in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Quick answer

Yes, with the right inputs — Nyandarua is moderately suited to Passion Fruit. Nyandarua's soil (pH 5.38, strongly acidic) gives Passion Fruit a suitability score of 73/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Nyandarua County is a solid choice for Passion Fruit, with a soil-match score of 73/100. At an average pH of 5.38 the soil is moderately acidic, below Passion Fruit's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 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 Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Passion Fruit is the #22 soil match of the 106 crops we assess for Nyandarua County. At current prices (about KES 70/kg) and a typical 8,000 kg/acre yield, a well-managed Passion Fruit crop here can gross roughly KES 560,000 per acre.
