Growing African Nightshade in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for African Nightshade (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above African Nightshade's preferred 5.5–7.5 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/medium demand — so the fertilizer plan below prioritises closing that deficit. African Nightshade 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 African Nightshade's minimum of 800 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, African Nightshade is the #96 soil match of the 106 crops we assess for Garissa County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Garissa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/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.
