Origin and geographic distribution Ruzi grass has its origin in the Ruzizi valley in eastern Zaire and Burundi. It is widely distributed on farms and experiment stations in most tropical countries including South-East Asia and the Pacific region.

Uses Ruzi grass is used as a forage for direct grazing of permanent pastures, in the open or under coconuts, and for feeding tethered or stalled ruminants.

Properties Ruzi grass is palatable and of excellent quality, with N concentrations ranging from 1.5—2.5% and in vitro DM digestibility from 50—75% (4—16 weeks old regrowth). It tolerates shade moderately, and drought fairly well. It has a high seed production potential. There are 230—250 seeds/g.

Ecology Ruzi grass is well adapted to the warm tropics with annual rainfall in excess of 1000 mm; it can withstand up to 5 dry months. It tolerates a range of soils but requires very fertile soil. It thrives best on well-drained sites.

Prospects The main value of ruzi grass lies in its reasonably high nutritive value and high seed production potential, but it is markedly less productive than Brachiaria decumbens. Its importance will decrease rapidly as current Brachiaria selection programmes result in alternatives which combine the above mentioned attributes with adaptation to low-fertility soils.
