Growing Taro (Nduma) in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for Taro (Nduma) (soil-match score 22/100) and will need significant amendment before planting. At an average pH of 6.55 the soil sits above Taro (Nduma)'s preferred 5.5–6.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 mg/kg) all meet Taro (Nduma)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Taro (Nduma), which favours loam. Kajiado receives approximately 500 mm/year — well below Taro (Nduma)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Taro (Nduma) is the #91 soil match of the 106 crops we assess for Kajiado County. Taro (Nduma)'s full potential is about 7,000 kg/acre (~KES 630,000/acre at KES 90/kg), but at Kajiado's 22/100 suitability a realistic target here is closer to 1,925 kg/acre (~KES 173,250/acre) unless the constraints above are addressed.

Better matched to Kajiado's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
