Digitaria eriantha , commonly known as digitgrass  or Pangola-grass ,  is a grass grown in tropical and subtropical climates. It grows relatively well in various soils, but grows especially well in moist soils. It is tolerant to droughts, water lodging, suppresses weeds and grows relatively quickly post grazing. This grass demonstrates great potential for farmers in Africa in subtropical and tropical climates, mostly for livestock feed. Digitaria eriantha is a monocot and in the family of Poaceae.

Digitaria eriantha Steud. Digitaria decumbens Stent, Digitaria eriantha subsp. Digitaria umfolozi is not recognized by major taxonomic authorities, but is sometimes described as a stoloniferous species with hairy leaves, up to 70 cm tall, from KwaZulu-Natal, South Africa, and is probably synonymous with Digitaria eriantha.
Pangola grass Digitaria eriantha Steud is a tropical grass widespread in many humid tropical and subtropical regions, used extensively for grazing, hay and silage. It is often considered to be one of the higher quality tropical grasses Cook et al. Digitaria eriantha is a perennial grass. This taxon comprises many morphologically different types that were once and sometimes still are considered to be separate species.
Its culms are simple or branched, 35 to cm tall. The leaf blades are cm long, mm wide, glabrous or hairy. The stolons spread over the surface of the ground and develop roots at the nodes. The stolons and stems are hairy. The inflorescence is a digitate single whorl or subdigitate 2 or more whorls panicle comprising racemes, cm long.
Very few viable seeds are produced Cook et al. Pangola grass is used extensively for pasture, hay and silage. It withstands very heavy grazing FAO, Regular grazing week intervals at cm to cm height is necessary to maintain the quality of pangola grass Cook et al. Pangola grass is native to tropical Southern Africa and is nowadays distributed to many humid subtropical and tropical areas.
It is tolerant of drought but low rainfall is the main limiting factor for production range and yield. The best yields have been recorded on full sun or well-drained moist soils. Nevertheless, good growth can be obtained on soils ranging from sands to heavy clays. It is generally considered to have low shade tolerance Ecocrop, Dry matter yields vary with genotype, environmental and management conditions.
The production of pangola grass pasture is sensitive to photoperiodism. Pangola grass pastures are also more productive during the warm season, and they can withstand high stocking density, trampling, and day rotations.
During the cool season, especially at higher elevations, the productivity of pangola grass is very low, and a rotation cycle of 60 days or more is recommended Fukumoto et al.
Pangola grass is one of the higher quality tropical grasses. Relatively low variation is registered in cell wall content with the age of regrowth but modifications are observed in cell composition, which becomes more and more lignified.
Like all tropical grasses, chemical and nutritive value of pangola grass vary with several factors including age of regrowth, season, fertilizer and genotype. The age of regrowth is the main factor of variation.
Pangola grass has relatively high concentrations of sodium in its tissues, compared with many other tropical grasses. The variations of the nutritional values of pangola grass according to the age of regrowth are presented in the table below:.
