Some sugarcane varieties are capable of fixing atmospheric nitrogen in association with the bacterium Gluconacetobacter diazotrophicus . Unlike legumes and other nitrogen-fixing plants that form root nodules in the soil in association with bacteria, G. diazotrophicus lives within the intercellular spaces of
228-541: A choice. West Indian planters, therefore, needed new workers, and they found cheap labour in China and India. The people were subject to indenture , a long-established form of contract, which bound them to unfree labour for a fixed term. The conditions where the indentured servants worked were frequently abysmal, owing to a lack of care among the planters. The first ships carrying indentured labourers from India left in 1836. The migrations to serve sugarcane plantations led to
285-516: A country with a mechanical agriculture looking for a high production of large fields, as in North America, sugarcanes are replanted after two or three harvests to avoid a lowering yields. In countries with a more traditional type of agriculture with smaller fields and hand harvesting, as in the French island of Réunion , sugarcane is often harvested up to 10 years before replanting. Sugarcane

This snake is sometimes referred to as Niibuyaa ( ニーブヤー ) in the Okinawan language . It
399-410: A perennial tropical grass , exhibits a unique growth pattern characterized by lateral shoots emerging at its base, leading to the development of multiple stems. These stems typically attain a height of 3 to 4 meters (approximately 10 to 13 feet) and possess a diameter of about 5 centimeters (approximately 2 inches). As these stems mature, they evolve into cane stalks, constituting a substantial portion of
456-460: A process called "affination". Its purpose is to wash away the sugar crystals' outer coating, which is less pure than the crystal interior. The remaining sugar is then dissolved to make a syrup, about 60% solids by weight. The sugar solution is clarified by the addition of phosphoric acid and calcium hydroxide , which combine to precipitate calcium phosphate . The calcium phosphate particles entrap some impurities and absorb others, and then float to

The venom of Ovophis okinavensis , like that of most vipers ,
855-846: Is closely linked to the migrations of the Austronesian peoples . Saccharum barberi was only cultivated in India after the introduction of S. officinarum . S. officinarum was first domesticated in New Guinea and the islands east of the Wallace Line by Papuans, where it is the modern center of diversity . Beginning around 6,000 BP , several strains were selectively bred from the native Saccharum robustum . From New Guinea, it spread westwards to Maritime Southeast Asia after contact with Austronesians, where it hybridized with Saccharum spontaneum . The second domestication center
912-416: Is common. Billets (stalks or stalk sections) harvested by a mechanical harvester are planted by a machine that opens and recloses the ground. Once planted, a stand can be harvested several times; after each harvest, the cane sends up new stalks, called ratoons . Successive harvests give decreasing yields, eventually justifying replanting. Two to 10 harvests are usually made depending on the type of culture. In
969-587: Is eaten raw, steamed, or toasted, and prepared in various ways in Southeast Asia, such as certain island communities of Indonesia as well as in Oceanic countries like Fiji . The direct use of sugar cane to produce ethanol for biofuel is projected to potentially surpass the production of white sugar as an end product. The term sugarcane is a combination of two words: "sugar" and "cane". The former ultimately derives from Sanskrit शर्करा ( śárkarā ) as
1026-498: Is harvested by hand and mechanically. Hand harvesting accounts for more than half of production, and is dominant in the developing world. In hand harvesting, the field is first set on fire. The fire burns up dry leaves, and chases away or kills venomous snakes, without harming the stalks and roots. Harvesters then cut the cane just above ground-level using cane knives or machetes . A skilled harvester can cut 500 kg (1,100 lb) of sugarcane per hour. Mechanical harvesting uses
1083-400: Is mainly hemotoxin with cytotoxicity factors. People are bitten when they step on this sluggish snake at night, or when tending crops by day. Although venom from this snake is not life-threatening usually, people still should seek medical attention promptly if they are bitten. Because of its relatively weak venom, antivenom is not produced. Sugar cane Sugarcane or sugar cane is
1140-429: Is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea . Sugarcane was an ancient crop of the Austronesian and Papuan people . The best evidence available today points to the New Guinea area as the site of the original domestication of Saccharum officinarum . It was introduced to Polynesia , Island Melanesia , and Madagascar in prehistoric times via Austronesian sailors. It
1197-418: Is sold as a food and dietary supplement. It is also a common ingredient in animal feed, and is used to produce ethanol, rum, and citric acid . Purer molasses syrups are sold as molasses, and may also be blended with maple syrup , invert sugars, or corn syrup . Both forms of molasses are used in baking. Sugar refining further purifies the raw sugar. It is first mixed with heavy syrup and then centrifuged in

#17327725073161254-455: Is sometimes produced immediately after the first stage at sugar-extraction mills, intended for local consumption. Sugar crystals appear naturally white in color during the crystallization process. Sulfur dioxide is added to inhibit the formation of color-inducing molecules and to stabilize the sugar juices during evaporation. Refineries, often located nearer to consumers in North America, Europe, and Japan, then produce refined white sugar, which
1311-728: Is southern China and Taiwan, where S. sinense was a primary cultigen of the Austronesian peoples. Words for sugarcane are reconstructed as *təbuS or *CebuS in Proto-Austronesian , which became *tebuh in Proto-Malayo-Polynesian . It was one of the original major crops of the Austronesian peoples from at least 5,500 BP. Introduction of the sweeter S. officinarum may have gradually replaced it throughout its cultivated range in maritime Southeast Asia. From Insular Southeast Asia, S. officinarum
1368-409: Is used for several purposes: The primary use of bagasse and bagasse residue is as a fuel source for the boilers in the generation of process steam in sugar plants. Dried filtercake is used as an animal feed supplement, fertilizer, and source of sugarcane wax . Molasses is produced in two forms: blackstrap , which has a characteristic strong flavor, and a purer molasses syrup. Blackstrap molasses

An article on sugarcane cultivation in Spain is included in Ibn al-'Awwam 's 12th-century Book on Agriculture . In colonial times, sugar formed one side of the triangle trade of New World raw materials, along with European manufactured goods, and African slaves . Christopher Columbus first brought sugarcane to
1539-858: The Caribbean (and the New World ) during his second voyage to the Americas, initially to the island of Hispaniola (modern day Haiti and the Dominican Republic ). The first sugar harvest happened in Hispaniola in 1501; many sugar mills were constructed in Cuba and Jamaica by the 1520s. The Portuguese introduced sugarcane to Brazil . By 1540, there were 800 cane sugar mills in Santa Catarina Island and another 2,000 on
1596-735: The Natal region of South Africa, it is normally due to anomalous climatic conditions in the region, such as warm ocean currents that sweep down the coast. In terms of altitude, sugarcane crops are found up to 1,600 m or 5,200 ft close to the equator in countries such as Colombia , Ecuador , and Peru . Sugarcane can be grown on many soils ranging from highly fertile, well-drained mollisols , through heavy cracking vertisols , infertile acid oxisols and ultisols , peaty histosols , to rocky andisols .

1824-829: The approach to crop management embraced in the cultivation of sugarcane. Ultimately, the successful cultivation of this valuable crop demands a thoughtful integration of various factors to optimize its growth and productivity. Sugarcane is a cash crop , but it is also used as livestock fodder. Sugarcane genome is one of the most complex plant genomes known, mostly due to interspecific hybridization and polyploidization. The two centers of domestication for sugarcane are one for Saccharum officinarum by Papuans in New Guinea and another for Saccharum sinense by Austronesians in Taiwan and southern China. Papuans and Austronesians originally primarily used sugarcane as food for domesticated pigs. The spread of both S. officinarum and S. sinense
1881-445: The cane during mechanical harvesting accelerates this decline. This decline is offset because a modern chopper harvester can complete the harvest faster and more efficiently than hand cutting and loading. Austoft also developed a series of hydraulic high-lift infield transporters to work alongside its harvesters to allow even more rapid transfer of cane to, for example, the nearest railway siding. This mechanical harvesting does not require
1938-429: The carbon. The purified syrup is then concentrated to supersaturation and repeatedly crystallized in a vacuum, to produce white refined sugar . As in a sugar mill, the sugar crystals are separated from the molasses by centrifuging. Additional sugar is recovered by blending the remaining syrup with the washings from affination and again crystallizing to produce brown sugar . When no more sugar can be economically recovered,
1995-609: The crop originated in Southeast Asia. As sugar was traded and spread West, this became سُكَّر ( sukkar ) in Arabic , zúcchero in Italian , zuccarum in Latin , and eventually sucre in both Middle French and Middle English . The second term "cane" began to be used alongside it as the crop was grown on plantations in the Caribbean . G anna is the Hindi word for sugarcane. Sugarcane,
2052-648: The eighth century, Muslim and Arab traders introduced sugar from medieval India to the other parts of the Abbasid Caliphate in the Mediterranean, Mesopotamia , Egypt , North Africa, and Andalusia . By the 10th century, sources state that every village in Mesopotamia grew sugarcane. It was among the early crops brought to the Americas by the Spanish, mainly Andalusians, from their fields in
2109-442: The entire plant, accounting for roughly 75% of its composition. A fully mature cane stalk generally comprises a composition of around 11–16% fiber, 12–16% soluble sugars, 2–3% nonsugar carbohydrates, and 63–73% water content. The successful cultivation of sugarcane hinges on a delicate interplay of several factors, including climatic conditions, soil properties, irrigation methods, fertilization practices, pest and disease management,

The cane beetle (also known as cane grub) can substantially reduce crop yield by eating roots; it can be controlled with imidacloprid (Confidor) or chlorpyrifos (Lorsban). Other important pests are the larvae of some butterfly/moth species, including
2223-491: The final molasses still contains 20–30% sucrose and 15–25% glucose and fructose. To produce granulated sugar , in which individual grains do not clump, sugar must be dried, first by heating in a rotary dryer, and then by blowing cool air through it for several days. Ribbon cane is a subtropical type that was once widely grown in the Southern United States, as far north as coastal North Carolina . The juice
2280-615: The global crop production over the 2000–2021 period. The Americas was the leading region in the production of sugar cane (52% of the world total). Once a major crop of the southeastern region of the United States, sugarcane cultivation declined there during the late 20th century, and is primarily confined to small plantations in Florida , Louisiana , and southeast Texas in the 21st century. Sugarcane cultivation ceased in Hawaii when
2337-422: The highest-yielding sugarcane-cultivating regions. Sugarcane consumes 9% of the world's potash fertilizer production. Although some sugarcanes produce seeds, modern stem cutting has become the most common reproduction method. Each cutting must contain at least one bud, and the cuttings are sometimes hand-planted. In more technologically advanced countries, such as the United States and Australia, billet planting

2394-490: The last operating sugar plantation in the state shut down in 2016. Sugarcane is cultivated in the tropics and subtropics in areas with a plentiful supply of water for a continuous period of more than 6–7 months each year, either from natural rainfall or through irrigation. The crop does not tolerate severe frosts. Therefore, most of the world's sugarcane is grown between 22°N and 22°S , and some up to 33°N and 33°S . When sugarcane crops are found outside this range, such as
2451-442: The north coast of Brazil, Demarara , and Suriname . Sugar, often in the form of molasses, was shipped from the Caribbean to Europe or New England, where it was used to make rum . The profits from the sale of sugar were then used to purchase manufactured goods, which were then shipped to West Africa, where they were bartered for slaves. The slaves were then brought back to the Caribbean to be sold to sugar planters. The profits from
2508-450: The removal of organic and nutrient-rich material, which can decrease future crop yields. It can also result in sediments and other pollutants being washed into aquatic habitats, which can result in a wide range of environmental issues, including eutrophication and acidification. Sugarcane cultivation can also result in soil compaction, which is caused by the use of heavy, infield machinery. Along with impacting invertebrate and fauna within
2565-483: The removal of soil at harvest, as well as improper irrigation practices, which can result in erosion. Erosion is especially significant when the sugarcane is grown on slopes or hillsides, which increases the rate of water runoff. Generally, it is recommended that sugarcane is not planted in areas with a slope greater than 8%. However, in certain areas, such as parts of the Caribbean and South Africa, slopes greater than 20% have been planted. Increased erosion can lead to
2622-509: The sale of the slaves were then used to buy more sugar, which was shipped to Europe. Toil in the sugar plantations became a main basis for a vast network of forced population movement , supplying people to work under brutal coercion. The passage of the 1833 Slavery Abolition Act led to the abolition of slavery through most of the British Empire , and many of the emancipated slaves no longer worked on sugarcane plantations when they had
2679-420: The selection of specific varieties, and the timing of the harvest. In terms of yield, the average production of cane stalk stands at 60–70 tonnes per hectare (equivalent to 24–28 long tons per acre or 27–31 short tons per acre) annually. However, this yield figure is not fixed and can vary significantly, ranging from 30 to 180 tonnes per hectare. This variance is contingent upon the level of knowledge applied and

An alternative to this "phosphatation" technique is " carbonatation ", which is similar, but uses carbon dioxide and calcium hydroxide to produce a calcium carbonate precipitate. After filtering any remaining solids, the clarified syrup is decolorized by filtration through activated carbon . Bone char or coal-based activated carbon is traditionally used in this role. Some remaining color-forming impurities are adsorbed by
2907-414: The workers are being exposed to hazards such as: high temperatures, harmful pesticides, and poisonous or venomous animals. This occurs during the process of cutting the sugarcane manually, causing physical ailments due to constant repetitive movements for hours every work day. Traditionally, sugarcane processing requires two stages. Mills extract raw sugar from freshly harvested cane and "mill-white" sugar

The theoretical possible yield for sugarcane is about 280 tonnes per hectare per year, and small experimental plots in Brazil have demonstrated yields of 236–280 tonnes of cane per hectare. From 2008 to 2016, production of standards-compliant sugarcane experienced a compound annual growth rate of about 52%, while conventional sugarcane increased at less than 1%. The cultivation of sugarcane can lead to increased soil loss through
3078-440: Was also introduced to southern China and India by Austronesian traders around 1200 to 1000 BC. The Persians and Greeks encountered the famous "reeds that produce honey without bees" in India between the sixth and fourth centuries BC. They adopted and then spread sugarcane agriculture. Merchants began to trade in sugar, which was considered a luxurious and expensive spice, from India. In the 18th century, sugarcane plantations began in
3135-680: Was exported to the USSR , where it received price supports and was ensured a guaranteed market. The 1991 dissolution of the Soviet state forced the closure of most of Cuba's sugar industry. Sugarcane remains an important part of the economy of Cuba, Guyana, Belize , Barbados , and Haiti, along with the Dominican Republic, Guadeloupe, Jamaica, and other islands. About 70% of the sugar produced globally comes from S. officinarum and hybrids using this species. Sugarcane cultivation requires
3192-558: Was extracted with horse- or mule-powered crushers; the juice was boiled, like maple syrup , in a flat pan, and then used in the syrup form as a food sweetener. It is not currently a commercial crop, but a few growers find ready sales for their product. In 2022, global production of sugarcane was 1.92 billion tonnes, with Brazil producing 38% of the world total, India with 23%, and China producing 5% (table). Worldwide, 26 million hectares were devoted to sugarcane cultivation in 2020. The average worldwide yield of sugarcane crops in 2022
