Growing Sesame (Simsim) in Busia
Soil suitability analysis based on Busia's nutrient profile
Possible but challenging — Busia is only marginally suited to Sesame (Simsim). Busia's soil (pH 5.29, strongly acidic) gives Sesame (Simsim) a suitability score of 50/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Sesame (Simsim) can be grown in Busia County, but the soil scores 50/100 and needs targeted management to reach full potential. At an average pH of 5.29 the soil is moderately acidic, below Sesame (Simsim)'s preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 mg/kg) all meet Sesame (Simsim)'s requirements, so a maintenance fertilizer programme is enough. Sesame (Simsim) prefers sandy soils, while Busia is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sesame (Simsim) is the #78 soil match of the 106 crops we assess for Busia County. Sesame (Simsim)'s full potential is about 250 kg/acre (~KES 87,500/acre at KES 350/kg), but at Busia's 50/100 suitability a realistic target here is closer to 156 kg/acre (~KES 54,600/acre) unless the constraints above are addressed.
Better matched to Busia's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
