Growing African Nightshade in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for African Nightshade (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 8.28 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 0.67 g/kg, P 42.1 mg/kg, K 387 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 Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 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 #78 soil match of the 106 crops we assess for Samburu County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Samburu's 8/100 suitability a realistic target here is closer to 500 kg/acre (~KES 25,000/acre) unless the constraints above are addressed.

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