Origin and geographic distribution Originally from the American tropics, Paspalum conjugatum is naturalized throughout South-East Asia and in many tropical countries of the world. It is abundant in Indonesia, the Philippines and the Pacific Islands.

Uses Paspalum conjugatum is used as a forage for grazing or in cut-and-carry systems, and is rated as very important as a natural pasture grass in coconut plantations. It is occasionally used as a lawn grass and is also regarded as an important weed in rice and plantation crops.|The Iban of Borneo use leaf decoctions in the treatment of wounds and sores, and in the Sepik area of Papua New Guinea crushed spikelets are used for the same purpose.

Properties At the pre-flowering stage, the N concentration in Paspalum conjugatum ranges from 1—2.2%. It is stated that only the young stage of the grass is suitable for grazing since the fruits tend to stick in the throats of livestock and choke them. The presence of a haemostatic glucoside, which reduced the time for blood clotting by 50%, has been reported for this species. Wet fruits may become very irritating as they easily stick to one's legs and clothing.

Ecology Paspalum conjugatum grows from near sea-level up to 1700 m altitude in open to moderately shaded places. It is adapted to humid climates. It is found under plantation crops and also along stream banks, roadsides and in disturbed areas on a variety of soils, often growing gregariously.

Prospects Because of the wide distribution of Paspalum conjugatum, research on agronomic aspects, such as improving DM yield and seed production, is desirable.
