Yes, with the right inputs — Nyandarua is moderately suited to Dolichos. Nyandarua's soil (pH 5.38, strongly acidic) gives Dolichos a suitability score of 65/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Nyandarua County is a solid choice for Dolichos, with a soil-match score of 65/100. Local soils average pH 5.38 — moderately acidic and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. Dolichos prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Dolichos is the #34 soil match of the 106 crops we assess for Nyandarua County. Dolichos's full potential is about 600 kg/acre (~KES 72,000/acre at KES 120/kg), but at Nyandarua's 65/100 suitability a realistic target here is closer to 488 kg/acre (~KES 58,560/acre) unless the constraints above are addressed.
