Compatibility with other species
Under heavy grazing, swazi grass combines well with creeping and other native and introduced legumes, especially if superphosphate is applied. Companion species include the following legumes: Desmodium triflorum, Zornia maculata, Glycine spp., Arachis pintoi, Aeschynomene falcata, Stylosanthes guianensis, Lotononis bainesii, Chamaecrista rotundifolia and Trifolium repens.
Weed control
In Australia, swazi grass is the best pasture species competitor to control giant Parramatta grass (Sporobolus fertilis) (Officer et al., 1998).
