Growing Eggplant in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Eggplant can be grown in Nyandarua County, but the soil scores 46/100 and needs targeted management to reach full potential. At an average pH of 5.38 the soil is moderately acidic, below Eggplant's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Eggplant prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 m, the county sits above Eggplant's preferred altitude ceiling of 1800 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Eggplant is the #73 soil match of the 106 crops we assess for Nyandarua County. Eggplant's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Nyandarua's 46/100 suitability a realistic target here is closer to 5,750 kg/acre (~KES 287,500/acre) unless the constraints above are addressed.

Better matched to Nyandarua's soil: Tea, Pyrethrum, and Potato — each scores higher on the same soil.
