Origin and geographic distribution The origin and natural distribution of Brachiaria humidicola extends throughout eastern and southern Africa. During the past 2—3 decades, it has been introduced to other tropical regions and has become a fairly widespread species in South-East Asia and the Pacific region.

Uses Koronivia grass is mainly used as a forage in permanent pastures that are grazed, and for erosion control. It has also proved to be useful as grazed ground cover in tree plantations.

Properties Koronivia grass has a reputation as a palatable forage with very low N concentrations, even during the growing season (0.6—1.0%), which can severely limit forage intake by ruminants. In vitro DM digestibility values range from 50—70%. The grass tolerates shade and poor drainage and is an effective seed producer. There are 200—260 seeds/g.

Ecology Koronivia grass is well adapted to the humid tropics but also thrives under sub-humid tropical conditions where it withstands 3—4 dry months. It grows well on a range of soils, including moist, poorly drained sites. It is particularly well adapted to acid, highly Al-saturated soils of low fertility.

Prospects Because of its aggressive, weed-suppressing growth, tolerance of overgrazing, adaptation to poorly drained sites, and low requirements regarding soil fertility, the present Koronivia grass cultivars will continue to play an important role in tropical pasture development. Their importance will only decline when new cultivars or other species become available which combine the above-mentioned features with better forage quality.
