Growing Cucumber in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Quick answer

Yes — Nairobi is well suited to Cucumber. Nairobi's soil (pH 6.85, near-neutral) gives Cucumber a suitability score of 88/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.

Nairobi County is well suited to Cucumber, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.8–7 band Cucumber 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/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Cucumber, which favours loam. On ShambaIQ's soil-match model, Cucumber is the #40 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 40/kg) and a typical 12,000 kg/acre yield, a well-managed Cucumber crop here can gross roughly KES 480,000 per acre.

Bags per acre in Nairobi
0.50.4

Nairobi's nitrogen (1.1 g/kg) is 92% of the 1.2 g/kg Cucumber needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
