Urochloa ramosa, (formerly Brachiaria ramosa) the browntop millet or Dixie signalgrass,[2] is an annual, millet grass belonging to the grass family (Poaceae). The native range of Urochloa ramosa is from Africa to tropical and subtropical Asia.
Description
It has
Growth
Seed germination can happen in up to 5 days and the rapidly growing crop can then be harvested in the next two months. Its fine stems and leaves allow the plant to dry sufficiently to be used as a dry hay product.[2]
Taxonomy
It was originally published as Brachiaria ramosa (L.) Stapf in D.Oliver & auct. suc. (eds.), Fl. Trop. Afr. 9: 542 in 1919, before being renamed and published and described by botanist T.Q.Nguyen in Novosti Sist. Vyssh. Rast. 3: 13 in 1966.[1][5][6]
The
The reconstructed Proto-Dravidian name for Brachiaria ramosa is *conna-l.[8]
It is named differently in Indian languages such as “korale” and “kadu-baragu” in Kannada, “andakorra” and “pedda-sama” in Telugu.[9]
Distribution
It is found in Afghanistan, Andaman Islands, Bangladesh, Benin, Burkina, Cambodia, Cameroon, Cape Verde, Chad, China, Djibouti, East Himalaya, Egypt, Eritrea, Ethiopia, Gambia, Guinea-Bissau, Gulf States, Hainan, India, Ivory Coast, Java, Kenya, Lesser Sunda Islands, Liberia, Malawi, Malaya, Mali, Mauritania, Mozambique, Myanmar, Nepal, New Guinea, Nicobar Islands, Niger, Nigeria, Northern Provinces (South Africa), Oman, Pakistan, Philippines, Saudi Arabia, Senegal, (island of) Socotra, Somalia, Sri Lanka, Sudan, Tanzania, Thailand, Vietnam, West Himalaya, Yemen and Zimbabwe.[1]
It has been introduced to parts of the United States (Alabama, Arkansas, Florida, Georgia, Hawaii, Illinois, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Texas and Virginia), South America (Peru), Africa (Madagascar, Mauritius, the island of Réunion), and parts of Australia,[10] (Christmas Island, Northern Territory, Queensland and Western Australia).[1]
In parts of America, it is considered an
Uses
In South Asia, it is traditionally cultivated as a
The grain is also used as a birdseed, and forage crop (in the US) for domestic animals and game animals (such as deer and rabbit) and for birds such as turkey, duck, dove, quail and pheasant.[2] Browntop millet can represent up to 10–25% of the diet of terrestrial and water birds.[15] Also 50% of ingested seed found in mourning dove's crops was browntop millet.[16] Urochloa ramosa is also used to suppress root-knot nematode populations in tomato and pepper crops in south-eastern states of America.[17]
Urochloa ramosa also has the ability to accumulate significant amounts of metals such as lead and zinc in its shoot and root tissues making it an important plant for remediation of contaminated soils (Lakshmi et al., 2013).[18]
Pests
It is affected by insect pests such as:[19]
- shoot flies Atherigona oryzae, Atherigona pulla, and Atherigona punctata
- caseworm Parapoynx stagnalis
- red hairy caterpillars Amsacta moorei
Within the US, army worms (Mythimna unipuncta) and grasshoppers are the common insect problems.[2]
