Growing Pigeon Peas in Siaya

Soil suitability analysis based on Siaya's nutrient profile

Siaya County is a solid choice for Pigeon Peas, with a soil-match score of 63/100. Local soils average pH 5.33 — moderately acidic and inside the 5–8 band Pigeon Peas prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.1 mg/kg) and potassium (134 mg/kg) all meet Pigeon Peas's requirements, so a maintenance fertilizer programme is enough. Pigeon Peas prefers sandy soils, while Siaya is largely clay loam, so drainage and organic-matter management matter more here. Pigeon Peas's full potential is about 600 kg/acre (~KES 45,000/acre at KES 75/kg), but at Siaya's 63/100 suitability a realistic target here is closer to 473 kg/acre (~KES 35,475/acre) unless the constraints above are addressed.
