Growing Banana in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Banana (soil-match score 12/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Banana's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Banana, which favours loam. Kitui receives approximately 500 mm/year — well below Banana's minimum of 1200 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 12/kg) and a typical 7,500 kg/acre yield, a well-managed Banana crop here can gross roughly KES 90,000 per acre.
