Urochloa Sabi grass is native to Africa. A perennial, loosely tufted grass sometimes rooting and branching from the lower nodes, variable in size and habit, occasionally with stolons and rarely rhizomes. It is mostly used as a permanent pasture but also makes good hay. It is effective for erosion control and other applications where rapid establishment and good ground cover is advantageous.
Management / Agronomy
Sabi grass can tolerate very heavy grazing, stock will selectively graze it when young and still find it more palatable than many other warm-season grasses when mature. It also recovers well from fire. Sabi grass combines well with legumes, although it can dominate in the short term if well fertilised. Good ground cover and rapid seedling development contribute to suppression of annual weeds. Despite growing naturally on soils with low available phosphorus, large responses to applied P have been measured. On very low fertility soils, applications of up to 35 kg/ha P may be necessary to maximise production. A critical P level in the tissue of 0.2% of the DM is proposed. It can also survive on low N soils by virtue of non-symbiotic nitrogen fixation in the rhizosphere. However, it does respond well to applied N.
