Growing Courgette (Zucchini) in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Yes, with the right inputs — Vihiga is moderately suited to Courgette (Zucchini). Vihiga's soil (pH 5.62, slightly acidic) gives Courgette (Zucchini) a suitability score of 59/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Courgette (Zucchini) can be grown in Vihiga County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.62 the soil is slightly acidic to near-neutral, below Courgette (Zucchini)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Courgette (Zucchini), which favours loam. On ShambaIQ's soil-match model, Courgette (Zucchini) is the #54 soil match of the 106 crops we assess for Vihiga County. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Vihiga's 59/100 suitability a realistic target here is closer to 8,850 kg/acre (~KES 442,500/acre) unless the constraints above are addressed.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.
