Growing African Nightshade in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for African Nightshade (soil-match score 35/100) and will need significant amendment before planting. Local soils average pH 6.55 — neutral and inside the 5.5–7.5 band African Nightshade prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.97 g/kg, P 20.6 mg/kg, K 257 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit African Nightshade, which favours loam. Kajiado receives approximately 500 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 #81 soil match of the 106 crops we assess for Kajiado County. African Nightshade's full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Kajiado's 35/100 suitability a realistic target here is closer to 2,188 kg/acre (~KES 109,400/acre) unless the constraints above are addressed.

Better matched to Kajiado's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
