Growing Dolichos in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Quick answer

Yes — Homa Bay is well suited to Dolichos. Homa Bay's soil (pH 5.27, strongly acidic) gives Dolichos a suitability score of 75/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Homa Bay County is well suited to Dolichos, scoring 75/100 on ShambaIQ's soil-match model. Local soils average pH 5.27 — moderately acidic and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (1.05 g/kg), phosphorus (13.8 mg/kg) and potassium (147 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. Dolichos prefers sandy loam soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Dolichos is the #16 soil match of the 106 crops we assess for Homa Bay County. At current prices (about KES 120/kg) and a typical 600 kg/acre yield, a well-managed Dolichos crop here can gross roughly KES 72,000 per acre.

Instruction
Dolichos (njahi) fixes its own nitrogen through rhizobia. Do NOT apply CAN — it suppresses nodulation and reduces yield. A starter dose of phosphorus at planting is enough.
