Growing Okra in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Okra can be grown in Nairobi County, but the soil scores 55/100 and needs targeted management to reach full potential. Local soils average pH 6.85 — neutral and inside the 6–7.5 band Okra prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Okra's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Okra, which favours loam. At 1700 m, the county sits above Okra's preferred altitude ceiling of 1300 m, where frost risk and cold nights reduce the crop's productivity. Okra's full potential is about 5,000 kg/acre (~KES 300,000/acre at KES 60/kg), but at Nairobi's 55/100 suitability a realistic target here is closer to 3,438 kg/acre (~KES 206,280/acre) unless the constraints above are addressed.
