Growing Eggplant in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Quick answer

Yes — Nairobi is well suited to Eggplant. Nairobi's soil (pH 6.85, near-neutral) gives Eggplant a suitability score of 84/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.

Nairobi County is well suited to Eggplant, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.5–7 band Eggplant prefers, so no lime is usually required. The main gap is nitrogen — measured at N 1.1 g/kg, P 22.1 mg/kg, K 236 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Eggplant, which favours loam. On ShambaIQ's soil-match model, Eggplant is the #59 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 50/kg) and a typical 10,000 kg/acre yield, a well-managed Eggplant crop here can gross roughly KES 500,000 per acre.

Nairobi's nitrogen (1.1 g/kg) is 92% of the 1.2 g/kg Eggplant needs, so the standard 1.5 bags/acre is raised to 2. Split it across two applications to limit leaching.
