Sorghum is a genus of flowering plants in the grass family Poaceae. Seventeen of the 25 species are native to Australia,with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized, in pasture lands. Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae (the tribe of big bluestem and sugarcane).
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses, commonly referred to collectively as grass. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns and pasture. Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath. With around 780 genera and around 12,000 species, Poaceae are the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae.
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth and Adelaide.
Africa is the world's second largest and second most-populous continent, being behind Asia in both categories. At about 30.3 million km2 including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Isthmus of Suez and the Red Sea to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognised sovereign states (countries), nine territories and two de facto independent states with limited or no recognition. The majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere.
One species, Sorghum bicolor ,native to Africa with many cultivated forms now, is an important crop worldwide, used for food (as grain and in sorghum syrup or "sorghum molasses"), animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are especially important in arid regions, where the grain is one of the staples for poor and rural people. These varieties form important components of forage in many tropical regions. S. bicolor is an important food crop in Africa, Central America, and South Asia, and is the fifth-most important cereal crop grown in the world.
Sorghum bicolor, commonly called sorghum and also known as great millet, durra, jowari, or milo, is a grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley. S. bicolor is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for forage, syrup production, and ethanol; they are taller than those grown for grain.
Food is any substance consumed to provide nutritional support for an organism. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth.
Sweet sorghum is any of the many varieties of the sorghum grass whose stalks have a high sugar content. Sweet sorghum thrives better under drier and warmer conditions than many other crops and is grown primarily for forage, silage, and syrup production. Although, in most of the United States the term molasses refers to a sweet syrup, made as a byproduct of sugarcane or sugar beet sugar extraction, sweet sorghum syrup is known as "sorghum molasses" in some regions of the U.S.
In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates which are lethal to grazing animals. When stressed by drought or heat, plants can also contain toxic levels of cyanide and nitrates at later stages in growth.
Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F). HCN is produced on an industrial scale and is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals.
Hordenine (N,N-dimethyltyramine) is an alkaloid of the phenethylamine class that occurs naturally in a variety of plants, taking its name from one of the most common, barley. Chemically, hordenine is the N-methyl derivative of N-methyltyramine, and the N,N-dimethyl derivative of the well-known biogenic amine tyramine, from which it is biosynthetically derived and with which it shares some pharmacological properties. Currently, hordenine is widely sold as an ingredient of nutritional supplements, with the claims that it is a stimulant of the central nervous system, and has the ability to promote weight loss by enhancing metabolism. In experimental animals, given sufficiently large doses parenterally, hordenine does produce an increase in blood pressure, as well as other disturbances of the cardiovascular, respiratory, and nervous systems. These effects are generally not reproduced by oral administration of the drug in test animals, and virtually no scientific reports of the effects of hordenine in human beings have been published.
Global demand for sorghum increased dramatically between 2013 and 2015 when China began purchasing US sorghum crops to use as livestock feed as a substitute for domestically grown corn. China purchased around $1 billion worth of American sorghum per year until April 2018 when China imposed retaliatory duties on American sorghum as part of the trade war between the two countries.
China, officially the People's Republic of China (PRC), is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometers (3,700,000 sq mi), it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, and the special administrative regions of Hong Kong and Macau.
A cereal is any grass cultivated for the edible components of its grain, composed of the endosperm, germ, and bran. The term may also refer to the resulting grain itself. Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. Edible grains from other plant families, such as buckwheat (Polygonaceae), quinoa (Amaranthaceae) and chia (Lamiaceae), are referred to as pseudocereals.
Many species once considered part of Sorghum, but now considered better suited to other genera include: Andropogon, Arthraxon, Bothriochloa, Chrysopogon, Cymbopogon, Danthoniopsis, Dichanthium, Diectomis, Diheteropogon, Exotheca, Hyparrhenia, Hyperthelia, Monocymbium, Parahyparrhenia, Pentameris, Pseudosorghum, Schizachyrium, and Sorghastrum .
Andropogon is a widespread genus of plants in the grass family, native to much of Asia, Africa, and the Americas as well as southern Europe and various oceanic islands.
Arthraxon, commonly known as carpetgrass, is a genus of Asian, African and Australian plants in the grass family, Poaceae, containing the following species:
Bothriochloa is a common and widespread genus of plants in the grass family native to many countries on all inhabited continents and many islands. They are often called beardgrass or bluestem.
The 3-Deoxyanthocyanidins and their glycosides are molecules with an anthocyanidins backbone lacking an hydroxyl group at position 3 on the C-ring. This nomenclature is the inverse of that which is commonly used in flavonoids, where the hydroxy-group is assumed absent if it is not specified, e. g. flavan-3-ol, flavan-4-ol, flavan-3,4-ol and flavonol.
Apigeninidin is a chemical compound belonging to the 3-deoxyanthocyanidins and that can be found in the Patagonian plant Ephedra frustillata and in the soybean. Apigeninidin is one of the principal pigments found in sorghum. Extremely high level of apigeninidin (49 mg/g) has been documented in sorghum leaf sheath. Like all anthocyanidins it exists in a variety of tautomers depending on pH and hydration, several of these bare the distinctive pyrylium core.
Baijiu, also known as shaojiu, is a category of at least a dozen Chinese liquors made from grain. Báijiǔ literally means "white (clear) alcohol" or liquor.
Millets (/ˈmɪlɪts/) are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food.
Panicum miliaceum is a grain crop with many common names including proso millet, broomcorn millet, common millet,, hog millet, Kashfi milletred millet, and white millet,. Archeological evidence suggests that crop was first domesticated before 10,000 BCE in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where approximately half a million acres are grown each year. The crop is notable both for its extremely short lifespan, with some varieties producing grain only 60 days after planting, and its low water requirements producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet Croatian: proso). Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass sub-family Panicoideae. While all of these crops utilize C4 photosynthesis, the others all employ the NADP-ME as their primary carbon shuttle pathway while the primary C4 carbon shuttle in proso millet is the NAD-ME pathway.
Eleusine coracana, or finger millet, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.
Lolium is a genus of tufted grasses in the bluegrass subfamily of the grass family. It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera.
Pearl millet is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. Cultivation subsequently spread and moved overseas to India. The earliest archaeological records in the Indian subcontinent date to around 2000 BC, and it spread rapidly through Northern Indian subcontinent reaching South India by 1500 BC, based on evidence from the site of Hallur. Cultivation also spread throughout eastern and southern parts of Africa. Pearl millet is widely grown in the northeastern part of Nigeria. It is a major source of food to the local villagers of that region. The crop grows easily in that region due to its ability to withstand harsh weather conditions like drought and flood. Records exist for cultivation of pearl millet in the United States in the 1850s, and the crop was introduced into Brazil in the 1960s.
Pennisetum is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. They are known commonly as fountaingrasses
Sorghum × drummondii (Sudangrass), is a hybrid-derived species of grass raised for forage and grain, native to tropical and subtropical regions of Eastern Africa. The plant is cultivated in Southern Europe, South America, Central America, North America and Southern Asia, for forage or as a cover crop.
Foxtail millet is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most important in East Asia. It has the longest history of cultivation among the millets, having been grown in India since antiquity. According to recent research, it was first domesticated in China around 6,000 BC. Other names for the species include dwarf setaria, foxtail bristle-grass, giant setaria, green foxtail, Italian millet, German millet, and Hungarian millet.
The Sudanian Savanna is a broad belt of tropical savanna that runs east and west across the African continent, from the Atlantic Ocean in the west to the western lowlands in the east. The Sahel, a belt of drier grasslands and acacia savannas, lies to the north, between the Sudanian Savanna and the Sahara Desert. To the south the forest-savanna mosaic is a transition zone between the Sudanian Savanna and the Guinean moist forests and Congolian forests that lie nearer the equator.
Johnson grass or Johnsongrass, Sorghum halepense, is a plant in the grass family, Poaceae, native to the Mediterranean region, but grows throughout Europe and the Middle East. The plant has been introduced to all continents except Antarctica, and most larger islands and archipelagos. It reproduces by rhizomes and seeds.
Dhurrin is a cyanogenic glycoside produced in many plants. Discovered in multiple sorghum varieties in 1906 as the culprit of cattle poisoning by hydrogen cyanide, dhurrin is most typically associated with Sorghum bicolor, the organism used for mapping the biosynthesis of dhurrin from tyrosine. Dhurrin's name is derived form the Arabic word for sorghum, transliterated to "Dhura."
Commercial sorghum is the cultivation and commercial exploitation of species of grasses within the genus Sorghum. These plants are used for grain, fibre and fodder. The plants are cultivated in warmer climates worldwide. Commercial Sorghum species are native to tropical and subtropical regions of Africa and Asia.
Ascochyta sorghi is a fungal plant pathogen. It causes Ascochyta leaf spot on barley that can also be caused by the related fungi Ascochyta hordei, Ascochyta graminea and Ascochyta tritici. It is considered a minor disease of barley.
Chitemene, from the ciBemba word meaning “place where branches have been cut for a garden”, is a system of slash and burn agriculture practiced throughout northern Zambia. It involves coppicing or pollarding of standing trees in a primary or secondary growth Miombo woodland, stacking of the cut biomass, and eventual burning of the cut biomass in order to create a thicker layer of ash than would be possible with in situ burning. Crops such as maize, finger millet, sorghum, or cassava are then planted in the burned area.
The Angoumois grain moth is a species of gelechioid moth. It is the type species of its genus Sitotroga, placed in the subfamily Pexicopiinae of the twirler moth family (Gelechiidae). Formerly, it was included in the "Chelariinae", which more recent authors do not separate from the Pexicopiinae and usually even do not consider a distinct tribe ("Chelariini") within them.
Pelopidas lyelli, the Lyell's swift, is a butterfly of the family Hesperiidae. It is found in New South Wales, the Northern Territory, Queensland and Western Australia, as well as Irian Jaya, Maluku, Papua New Guinea, the Solomon Islands and Vanuatu.
Sorghum is a cultivated cereal. The genus Sorghum contains the crop and its wild relatives:
Sorghum is an important staple crop for more than 500 million people in sub-Saharan Africa and South Asia, including many people in Nepal. In statistics collected from 1992-1994 about general millet, Nepal had an area of 0.21 million ha, with a yield rate of 1.14 (t/ha), and produced around 0.24 million tons of sorghum. The entirety of the crop is highly valued, with both the grain and the stem being utilized. The Terai region of Nepal tends to be more tropical which is ideal for the growth of sorghum. It tolerates hot climates better than maize or soybeans. For subsistence farmers, like those in Nepal, fertilizers are not necessary and the crop is frequently harvested by hand.
