Growing Eggplant in Samburu
Soil suitability analysis based on Samburu's nutrient profile
Generally not ideal — Samburu is poorly suited to Eggplant. Samburu's soil (pH 8.28, alkaline) gives Eggplant a suitability score of 16/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.
Samburu County is a challenging environment for Eggplant (soil-match score 16/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Eggplant's preferred 5.5–7 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/high/high demand — so the fertilizer plan below prioritises closing that deficit. Eggplant 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 Eggplant's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Eggplant is the #60 soil match of the 106 crops we assess for Samburu County. Eggplant's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Samburu's 16/100 suitability a realistic target here is closer to 2,000 kg/acre (~KES 100,000/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.
