Growing Jute Mallow (Mrenda) in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Jute Mallow (Mrenda) (soil-match score 17/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Jute Mallow (Mrenda)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Jute Mallow (Mrenda) prefers loam soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Jute Mallow (Mrenda)'s minimum of 600 mm — so supplemental irrigation would be essential for this crop. Jute Mallow (Mrenda)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Samburu's 17/100 suitability a realistic target here is closer to 1,063 kg/acre (~KES 53,150/acre) unless the constraints above are addressed.
