Growing Courgette (Zucchini) in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Courgette (Zucchini) (soil-match score 14/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Courgette (Zucchini)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Courgette (Zucchini) prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Courgette (Zucchini)'s minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Courgette (Zucchini) is the #32 soil match of the 106 crops we assess for Garissa County. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Garissa's 14/100 suitability a realistic target here is closer to 2,100 kg/acre (~KES 105,000/acre) unless the constraints above are addressed.

Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
