Growing Taro (Nduma) in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Taro (Nduma) (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Taro (Nduma)'s preferred 5.5–6.5 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 medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Taro (Nduma), which favours loam. Kitui receives approximately 500 mm/year — well below Taro (Nduma)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 90/kg) and a typical 8,000 kg/acre yield, a well-managed Taro (Nduma) crop here can gross roughly KES 720,000 per acre.
