Dichanthium annulatum is a species of grass in the family Poaceae. It is commonly used as a forage for livestock.
Common names include marvel grass, Diaz bluestem, Kleberg bluestem, Hindi grass, ringed dichanthium, sheda grass, medio bluestem (var. papillosum), [1] jargu grass, Delhi grass, vuda bluegrass, two-flowered golden-beard, [2] Santa Barbara grass.
It is native to tropical Asia, the Middle East, and parts of Africa. In India, it is very important in agriculture. [3] It has been introduced to many other parts of the world for cultivation, and it has become naturalized in some places, such as Australia. [1]
This species is quite variable. [3] [4] In general, it is a perennial grass often with stolons. The stems spread outwards, then grow erect at the ends. A stem may be a meter long and reach about 60 centimeters in erect height. [5] Each node on the stem is encircled with a ring of hairs. [2] The rough-haired leaf blades are up to 30 centimeters long. [5] The inflorescence is an array of purplish or green branches each up to 7 centimeters long. There are generally 2 to 9 branches, but sometimes up to 15. [2] The spikelet may be well over 2 centimeters long, including its long awn. The awn is twisted and has two bends in it. [5] The root system goes no deeper than one meter. [2] [6]
This grass often reproduces by apomixis, producing seeds without fertilization. It does reproduce sexually at times. Plants can be diploid, tetraploid, or hexaploid. [2]
This is a popular pasture grass in many areas. It can be used in fields for grazing livestock, and cut for hay and silage. It is tolerant of varied soil conditions, including soils high in clay and sand, poorly drained soils, and soils that are somewhat alkaline and saline. It forms a turf that can stand up to grazing pressure. It can recover from fire and drought, but it is less tolerant of frost and shade. It does not require fertilizer but it does respond well to a small amount of supplemental nitrogen. [2] Horses and cattle find it very palatable. [3]
While it can aggressively outcompete many other plants, it thrives with some types of companion species, such as the grasses Bothriochloa insculpta , Dichanthium aristatum , and D. caricosum , and the legumes Medicago sativa , Stylosanthes hamata , and S. seabrana . [2]
The grass can also be used to revegetate degraded grasslands. [2] It is a very effective binding plant for erosion control. [7]
This is an especially favored pasture grass species in India. There it is familiar, widely planted, and successful. [4] [6] [7]
This grass is host to a number of fungus species, such as Balansia sclerotica , Cerebella andropogonis , Chaetostroma atrum , Cochliobolus cymbopogonis , Curvularia andropogonis , C. lunata , C. robusta , Ellisiella caudata , Jamesdicksonia obesa , Phyllachora ischaemi , Physoderma dichanthicola , Pithomyces graminicola , Puccinia cesatii , P. duthiae , P. propinqua , Sclerospora dichanthicola , Sphacelotheca annulata , S. andropogonis-annulati , Tolyposporella obesa , Uredo susica , Uromyces andropogonis-annulati , U. clignyi , and Ustilago duthiei . Most are not very destructive to the grass, but it is susceptible to ergot (Claviceps spp.). [2]
It is also a host for the parasitic plant Striga lutea . [2]
This grass can escape cultivation and take hold in the wild. It is able to grow in harsh and disturbed habitat types, such as roadsides. It can become a weed. [4] It is an invasive species in Fiji, Hawaii, and New Caledonia and has displaced native grasses in large areas of south Texas. [8] It is cited as a factor in the decline of the slender rushpea (Hoffmannseggia tenella) a federally listed endangered plant of the United States. [9]
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible cellulose within grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming.
Andropogon gerardi, commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot.
Holcus lanatus is a perennial grass. The specific epithet lanatus is Latin for 'woolly' which describes the plant's hairy texture. Common names include Yorkshire fog, tufted grass, and meadow soft grass. In North America, where it is an invasive species, names include velvet grass and common velvet grass.
Macroptilium atropurpureum, commonly referred to as purple bush-bean, or siratro is a perennial legume recognized by its climbing, dense, green vines and deep purple flowers. The plant is indigenous to the tropical and subtropical regions of North, Central, and South America, as far north as Texas in the USA and as far south as Peru and Brazil. It has been introduced for use as a food for stock to many tropical regions around the world. It has become an invasive pest plant in a number of areas, including the north-eastern coast of Australia. Rich in protein, M. atropurpureum is commonly used for cattle pastures intercropped with grass, used in hay, or as a ground cover to prevent soil erosion and to improve soil quality.
Bothriochloa barbinodis is a species of grass known by the common name cane bluestem. It is native to the Americas, including most of South and Central America, Mexico, and the southernmost continental United States from California to Florida.
Chloris gayana is a species of grass known by the common name Rhodes grass. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species.
Dichanthium, known commonly as bluestem or bluegrass, is a genus of African, Asian, and Australian plants in the grass family.
Setaria sphacelata is a tall African grass, also known as South African pigeon grass and African bristlegrass. It is native to tropical and subtropical Africa, and is extensively cultivated globally as a pasture grass and for cut fodder. 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.
