Growing Sesame (Simsim) in Trans Nzoia
Soil suitability analysis based on Trans Nzoia's nutrient profile
Possible but challenging — Trans Nzoia is only marginally suited to Sesame (Simsim). Trans Nzoia's soil (pH 5.93, slightly acidic) gives Sesame (Simsim) a suitability score of 49/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.
Sesame (Simsim) can be grown in Trans Nzoia County, but the soil scores 49/100 and needs targeted management to reach full potential. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.5–7 band Sesame (Simsim) prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Sesame (Simsim)'s requirements, so a maintenance fertilizer programme is enough. Sesame (Simsim) prefers sandy soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sesame (Simsim) is the #92 soil match of the 106 crops we assess for Trans Nzoia County. Sesame (Simsim)'s full potential is about 250 kg/acre (~KES 87,500/acre at KES 350/kg), but at Trans Nzoia's 49/100 suitability a realistic target here is closer to 153 kg/acre (~KES 53,550/acre) unless the constraints above are addressed.
Better matched to Trans Nzoia's soil: Kale (Sukuma Wiki), Finger Millet, and Sweet Potato — each scores higher on the same soil.
