Setaria sphacelata is a tall African grass, also known as South African pigeon grass [2] and African bristlegrass. [3] It is native to tropical and subtropical Africa, and is extensively cultivated globally as a pasture grass and for cut fodder. [2] [4] This is a rhizomatous perennial grass producing flattened, hairless, blue-green stems up to 2 m tall. The inflorescence is a dense, narrow panicle of bristly, orange-tinged spikelets up to 25 cm long. [2]

In Africa, Setaria sphacelata seed heads are an important food source for several bird species, including the long-tailed widowbird. [5]

Commercial cultivars have been developed for various climates and soil conditions. All cultivars are high in oxalate, making them generally unsuitable for horses. Recognised pests in cultivation include the buffel grass seed caterpillar (Mampava rhodoneura) and the fungus Pyricularia trisa. [6]

Setaria sphacelata is a good quality forage for ruminants such as cattle, sheep and goats. It can be fed fresh and ensiled. [7]

Setaria sphacelata has become naturalised in many countries and is a significant environmental weed in three Australian states. [2] [4] [8]

<i>Centrosema pubescens</i>

Brachiaria ruziziensis or Congo grass is a forage crop that is grown throughout the humid tropics. With fast growth at the beginning of the wet season due to strong seedling vigour, ease of establishment, good seed production and yield and the ability to suppress weeds it has the ability to become developed into the most important forage crop planted in the tropics. With the aid of genomic tools to research the genotype and gain more information there is the ability to increase breeding programs which are currently rather limited.

<i>Digitaria eriantha</i> Species of grass

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.
