Growing Eggplant in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Quick answer

Generally not ideal — Kilifi is poorly suited to Eggplant. Kilifi's soil (pH 6.24, slightly acidic) gives Eggplant a suitability score of 7/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.

Kilifi County is a challenging environment for Eggplant (soil-match score 7/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–7 band Eggplant prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Eggplant, which favours loam. At 150 m, the county sits below Eggplant's preferred altitude range (500–1800 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Eggplant is the #65 soil match of the 106 crops we assess for Kilifi County. Eggplant's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Kilifi's 7/100 suitability a realistic target here is closer to 875 kg/acre (~KES 43,750/acre) unless the constraints above are addressed.

Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.

Bags per acre in Kilifi
2.251.5

Kilifi's nitrogen (0.8 g/kg) is 67% of the 1.2 g/kg Eggplant needs, so the standard 1.5 bags/acre is raised to 2.25. Split it across two applications to limit leaching.
