88-636: The Chernyakhov culture territorially replaced its predecessor, the Zarubintsy culture . Both cultures were discovered by the Czech-russian archaeologist, Vikentiy Khvoyka , who conducted numerous excavations around Kyiv and its vicinity. With the invasion of Huns , the culture declined and was replaced with the Penkovka culture (or the culture of the Antes ). Similarities have been noted between

176-693: A blended culture resulting from Przeworsk and steppe interactions. Furthermore, he altogether denies the existence of Goths prior to the 3rd century. Kulikowski states that no Gothic people, nor even a noble kernel , migrated from Scandinavia or the Baltic. Rather, he suggests that the "Goths" formed in situ . Like the Alemanni or the Franks, the Goths were a "product of the Roman frontier". Other influences, such as

264-487: A cemetery site in Transylvania , Romania , spelled S î ntana de Mureș before 1993. This site is also known as Marosszentanna , the formerly official Hungarian name under which the first excavations took place. The dual name reflects past preferential use by different schools of history ( Romanian and Soviet ) to designate the culture. In the earlier half of the 20th century, scholars spent much energy debating

352-438: A combination of artificial and natural selection . This complexity and diversity of status has led to much confusion in the naming of wheats. Hexaploid species (6N) Tetraploid species (4N) Diploid species (2N) The wild species of wheat, along with the domesticated varieties einkorn , emmer and spelt , have hulls. This more primitive morphology (in evolutionary terms) consists of toughened glumes that tightly enclose

440-535: A decline in climate resilience of wheat has been observed. Hunter-gatherers in West Asia harvested wild wheats for thousands of years before they were domesticated , perhaps as early as 21,000 BC, but they formed a minor component of their diets. In this phase of pre-domestication cultivation, early cultivars were spread around the region and slowly developed the traits that came to characterise their domesticated forms. Repeated harvesting and sowing of

528-478: A decrease in the number of settlements in the original Pomeranian Wielbark heartland as evidence of a significant population movement. Combined with Jordanes' account, Heather concludes that a movement of Goths (and other east Germanic groups such as Heruli and Gepids ) "played a major role in the creation of the Cernjachove culture". He clarifies that this movement was not a single, royal-led, migration, but

616-586: A few types with general similarities to Wielbark types". Michael Kulikowski also challenges the Wielbark connection, highlighting that the greatest reason for Wielbark-Chernyakhov connection derives from a "negative characteristic" (i.e., the absence of weapons in burials), which is less convincing proof than a positive one. He argues that the Chernyakhov culture could just as likely have been an indigenous development of local Pontic, Carpic or Dacian cultures, or

704-409: A good crop of grain. The farmer may intervene while the crop is growing to add fertilizer , water by irrigation , or pesticides such as herbicides to kill broad-leaved weeds or insecticides to kill insect pests. The farmer may assess soil minerals, soil water, weed growth, or the arrival of pests to decide timely and cost-effective corrective actions, and crop ripeness and water content to select

792-543: A large pit and surrounded by food and ornaments, such as spiral bracelets and Middle to Late La-Tene type fibulae . The disintegration of the Zarubintsy culture has been linked with the emigration of its population in several directions. Density of settlements in the central region decreases, as late Zarubintsy groups appear radially, especially southward into the forest-steppe regions of the middle Dnieper, Desna, and southern Donets rivers. Influences upon local cultures in

880-470: A less reliable method based on grain size. Einkorn and emmer are considered two of the founder crops cultivated by the first farming societies in Neolithic West Asia. These communities also cultivated naked wheats ( T. aestivum and T. durum ) and a now-extinct domesticated form of Zanduri wheat ( T. timopheevii ), as well as a wide variety of other cereal and non-cereal crops. Wheat

968-681: A low quality for human nutrition, according to the DIAAS protein quality evaluation method. Though they contain adequate amounts of the other essential amino acids, at least for adults, wheat proteins are deficient in the essential amino acid lysine . Because the proteins present in the wheat endosperm (gluten proteins) are particularly poor in lysine, white flours are more deficient in lysine compared with whole grains. Significant efforts in plant breeding are made to develop lysine-rich wheat varieties, without success, as of 2017 . Supplementation with proteins from other food sources (mainly legumes )

1056-450: A major contribution to the nutritional welfare of the poor. Some wheat species are diploid , with two sets of chromosomes , but many are stable polyploids , with four sets of chromosomes ( tetraploid ) or six ( hexaploid ). Einkorn wheat ( Triticum monococcum ) is diploid (AA, two complements of seven chromosomes, 2n=14). Most tetraploid wheats (e.g. emmer and durum wheat) are derived from wild emmer , T. dicoccoides . Wild emmer

1144-475: A major contributor to increased grain output. More widely over the last 40 years, a massive increase in fertilizer use together with the increased availability of semi-dwarf varieties in developing countries, has greatly increased yields per hectare. In developing countries, use of (mainly nitrogenous) fertilizer increased 25-fold in this period. However, farming systems rely on much more than fertilizer and breeding to improve productivity. A good illustration of this

1232-552: A minority are in east–west orientation. Funerary gifts often include fibulae , belt buckles, bone combs, glass drinking vessels and other jewelry. Women's burials in particular shared very close similarities with Wielbark forms - buried with two fibulae, one on each shoulder. Like in the Wielbark culture, Chernyakhov burials usually lack weapons as funerary gifts, except in a few cremation burials reminiscent of Przeworsk influences. Although cremation burials are traditionally associated with Dacian, Germanic and Slavic peoples, and inhumation

1320-699: A minority of burials containing weapons, are seen from the Przeworsk and Zarubinec cultures. The latter has been connected with early Slavs . In 2019, a genetic study of various cultures of the Eurasian Steppe , including the Chernyakhov culture, was published in Current Biology . Out of 31 ancient individuals tested, three samples from three individuals which the authors identified with "Ukrainian post-Scythian Chernyakhiv culture" were analyzed. They "overlapped with modern Europeans, representing

1408-453: A sense of ethnic distinction was kept between the disparate peoples. Some of the autochthonous elements persist, and become even more widespread, after the demise of the Gothic elite – a phenomenon associated with the rise and expansion of the early Slavs . Whilst acknowledging the mixed origins of the Chernyakhov culture, Peter Heather suggests that the culture is ultimately a reflection of

1496-470: A source of straw , which could be used for fuel, wicker-making , or wattle and daub construction. Domestic wheat was quickly spread to regions where its wild ancestors did not grow naturally. Emmer was introduced to Cyprus as early as 8600 BC and einkorn c.  7500 BC ; emmer reached Greece by 6500 BC, Egypt shortly after 6000 BC, and Germany and Spain by 5000 BC. "The early Egyptians were developers of bread and

1584-426: A viable crop. When the use of seed drills replaced broadcasting sowing of seed in the 18th century, another great increase in productivity occurred. Yields of pure wheat per unit area increased as methods of crop rotation were applied to land that had long been in cultivation, and the use of fertilizers became widespread. Improved agricultural husbandry has more recently included pervasive automation , starting with

1672-418: A wheat plant is known as the flag leaf. It is denser and has a higher photosynthetic rate than other leaves, to supply carbohydrate to the developing ear. In temperate countries the flag leaf, along with the second and third highest leaf on the plant, supply the majority of carbohydrate in the grain and their condition is paramount to yield formation. Wheat is unusual among plants in having more stomata on

1760-506: A year's supply. Wheat grain was stored after threshing , with the chaff removed. It was then processed into flour using ground stone mortars . Bread made from ground einkorn and the tubers of a form of club rush ( Bolboschoenus glaucus ) was made as early as 12,400 BC. At Çatalhöyük ( c.  7100–6000 BC ), both wholegrain wheat and flour was used to prepare bread, porridge and gruel . Apart from food, wheat may also have been important to Neolithic societies as

1848-452: Is Australian wheat growing in the southern winter cropping zone, where, despite low rainfall (300 mm), wheat cropping is successful even with relatively little use of nitrogenous fertilizer. This is achieved by crop rotation with leguminous pastures. The inclusion of a canola crop in the rotations has boosted wheat yields by a further 25%. In these low rainfall areas, better use of available soil-water (and better control of soil erosion)

1936-574: Is a rich source (20% or more of the Daily Value , DV) of multiple dietary minerals , such as manganese , phosphorus , magnesium , zinc , and iron (table). The B vitamins , niacin (36% DV), thiamine (33% DV), and vitamin B6 (23% DV), are present in significant amounts (table). Wheat is a significant source of vegetable proteins in human food, having a relatively high protein content compared to other major cereals. However, wheat proteins have

2024-400: Is achieved by retaining the stubble after harvesting and by minimizing tillage. Pests and diseases consume 21.47% of the world's wheat crop annually. There are many wheat diseases, mainly caused by fungi, bacteria, and viruses . Plant breeding to develop new disease-resistant varieties, and sound crop management practices are important for preventing disease. Fungicides, used to prevent

2112-459: Is also important to identify periods of higher risk from the climate. Farmers benefit from knowing when the 'flag leaf' (last leaf) appears, as this leaf represents about 75% of photosynthesis reactions during the grain filling period, and so should be preserved from disease or insect attacks to ensure a good yield. Several systems exist to identify crop stages, with the Feekes and Zadoks scales being

2200-402: Is commonly used to compensate for this deficiency, since the limitation of a single essential amino acid causes the others to break down and become excreted, which is especially important during growth. Consumed worldwide by billions of people, wheat is a significant food for human nutrition, particularly in the least developed countries where wheat products are primary foods. When eaten as

2288-484: Is evidence they also traded wild animal skins with Black Sea towns. Some sites were defended by ditches and banks, structures thought to have been built to defend against nomadic tribes from the steppe. Dwellings were either of surface or semi-subterranean types, with posts supporting the walls, a hearth in the middle, and large conic pits located nearby. Inhabitants practiced cremation. Cremated remains were either placed in large, hand-made ceramic urns, or were placed in

2376-418: Is greater than for all other crops combined. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is increasing as a result of the worldwide industrialization process and westernization of diets . Wheat became a central agriculture endeavor in the worldwide British Empire in

2464-477: Is greater than for all other crops combined. In 2021, world wheat production was 771 million tonnes (850 million short tons), making it the second most-produced cereal after maize (known as corn in North America and Australia; wheat is often called corn in countries including Britain). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through

2552-473: Is itself the result of a hybridization between two diploid wild grasses, T. urartu and a wild goatgrass such as Ae. speltoides . The hybridization that formed wild emmer (AABB, four complements of seven chromosomes in two groups, 4n=28) occurred in the wild, long before domestication, and was driven by natural selection . Hexaploid wheats evolved in farmers' fields as wild emmer hybridized with another goatgrass, Ae. squarrosa or Ae. tauschii , to make

2640-629: Is likely to be prioritised in drought-adapted crops, while stem non-structural carbohydrate is prioritised in varieties developed for countries where disease is a bigger issue. Depending on variety, wheat may be awned or not awned. Producing awns incurs a cost in grain number, but wheat awns photosynthesise more efficiently than their leaves with regards to water usage, so awns are much more frequent in varieties of wheat grown in hot drought-prone countries than those generally seen in temperate countries. For this reason, awned varieties could become more widely grown due to climate change . In Europe, however,

2728-458: Is more diverse, with domesticated varieties falling into two major groups: hulled or non-shattering, in which threshing separates the whole spikelet ; and free-threshing, where the individual grains are separated. Both varieties probably existed in prehistory, but over time free-threshing cultivars became more common. Wild emmer was first cultivated in the southern Levant , as early as 9600 BC. Genetic studies have found that, like einkorn, it

2816-399: Is normally planted after tilling the soil by ploughing and then harrowing to kill weeds and create an even surface. The seeds are then scattered on the surface, or drilled into the soil in rows. Winter wheat lies dormant during a winter freeze. It needs to develop to a height of 10 to 15 cm before the cold intervenes, so as to be able to survive the winter; it requires a period with

2904-511: Is not the same as a wheat allergy . Other diseases triggered by eating wheat are non-coeliac gluten sensitivity (estimated to affect 0.5% to 13% of the general population ), gluten ataxia , and dermatitis herpetiformis . Certain short-chain carbohydrates present in wheat, known as FODMAPs (mainly fructose polymers ), may be the cause of non-coeliac gluten sensitivity. As of 2019 , reviews have concluded that FODMAPs only explain certain gastrointestinal symptoms, such as bloating , but not

2992-562: Is now attested by about 500 sites. The culture was named after finds of cremated remains in the village of Zarubyntsi  [ uk ] on the Dnieper. The Zarubintsy culture is possibly connected to the pre-Slavic ancestors of early Slavs ( proto-Slavs ), with possible links to the peoples of the Dnieper basin . The culture was influenced by the La Tène culture and the nomads of

3080-484: Is suggestive of nomadic practice, careful analysis suggests that the mixed burials were of an earlier period, whilst toward the end there was a trend toward inhumation burials without grave goods. This could be the result of the influences of Christianity, but could just as easily be explained in terms of an evolution of non-Christian beliefs about the afterlife. Pottery was predominantly of local production, being both wheel and hand-made. Wheel made pottery predominated, and

3168-493: Is valuable to impart viscoelastic functional qualities in dough , enabling the preparation of diverse processed foods such as breads, noodles, and pasta that facilitate wheat consumption. Raw red winter wheat is 13% water, 71% carbohydrates including 12% dietary fiber , 13% protein , and 2% fat (table). Some 75–80% of the protein content is as gluten . In a reference amount of 100 grams (3.5 oz), wheat provides 1,368 kilojoules (327 kilocalories) of food energy and

3256-540: The Getae - Dacians (some authors believe that the Getae-Dacians played the leading role in the creation of the culture). Both inhumation and cremation were practiced. The dead were buried with grave goods – pottery, iron implements, bone combs, personal ornaments, although in later periods grave goods decrease. Of the inhumation burials, the dead were usually buried in a north–south axis (with head to north), although

3344-631: The Wielbark culture . Originating in the mid-1st century, it spread from south of the Baltic Sea (from territory around later Pomerania ) down the Vistula in the 2nd and 3rd centuries. Wielbark elements are prominent in the Chernyakhov zone, such as typical 'Germanic' pottery, brooch types and female costume, and, in particular, weaponless bi-ritual burials. Although cultures may spread without substantial population movements, Heather draws attention to

3432-436: The extra-digestive symptoms that people with non-coeliac gluten sensitivity may develop. Other wheat proteins, amylase-trypsin inhibitors, have been identified as the possible activator of the innate immune system in coeliac disease and non-coeliac gluten sensitivity. These proteins are part of the plant's natural defense against insects and may cause intestinal inflammation in humans. In 2022, world wheat production

3520-853: The hexaploid wheats including bread wheat . A 2007 molecular phylogeny of the wheats gives the following not fully-resolved cladogram of major cultivated species; the large amount of hybridisation makes resolution difficult. Markings like "6N" indicate the degree of polyploidy of each species: Barley 2N, rye 2N/4N, and other cereals Triticum monococcum ( einkorn ) 2N × Aegilotriticum hybrids ( Aegilops x Triticum ) 6N Triticum timopheevii (zanduri wheat) and others 4N Triticum aestivum ( common or bread wheat ) 6N Triticum durum/turgidum ( durum wheat) 4N Triticum spelta ( spelt ) 6N Triticum turanicum ( khorasan wheat ) 4N Triticum dicoccum ( emmer ) 4N many other species During 10,000 years of cultivation, numerous forms of wheat, many of them hybrids , have developed under

3608-599: The steppes (the Scythians and the Sarmatians ). The Scythian and Sarmatian influence is evident especially in pottery , weaponry , and domestic and personal objects. The bearers of the culture engaged in agriculture, documented by numerous finds of sickles. Pobol suggested that the culture experienced a transition from swidden (' slash-and-burn ') to plough-type cultivation. In addition, they raised animals. Remains included sheep, goat, cattle, horses, and swine. There

3696-488: The whole grain , wheat is a source of multiple nutrients and dietary fiber . In a small part of the general population, gluten – which comprises most of the protein in wheat – can trigger coeliac disease , noncoeliac gluten sensitivity , gluten ataxia , and dermatitis herpetiformis . Wheat is a stout grass of medium to tall height. Its stem is jointed and usually hollow, forming a straw. There can be many stems on one plant. It has long narrow leaves, their bases sheathing

3784-427: The whole grain , wheat supplies multiple nutrients and dietary fiber recommended for children and adults. In genetically susceptible people, wheat gluten can trigger coeliac disease . Coeliac disease affects about 1% of the general population in developed countries . The only known effective treatment is a strict lifelong gluten-free diet . While coeliac disease is caused by a reaction to wheat proteins, it

3872-617: The 19th century, and remains of great importance in Australia, Canada and India. In Australia, with vast lands and a limited work force, expanded production depended on technological advances, especially regarding irrigation and machinery. By the 1840s there were 900 growers in South Australia . They used "Ridley's Stripper", a reaper-harvester perfected by John Ridley in 1843, to remove the heads of grain. In Canada, modern farm implements made large scale wheat farming possible from

3960-513: The 20th century, global wheat output expanded by about 5-fold, but until about 1955 most of this reflected increases in wheat crop area, with lesser (about 20%) increases in crop yields per unit area. After 1955 however, there was a ten-fold increase in the rate of wheat yield improvement per year, and this became the major factor allowing global wheat production to increase. Thus technological innovation and scientific crop management with synthetic nitrogen fertilizer , irrigation and wheat breeding were

4048-415: The 3rd century AD, central late Zarubintsy sites 're-arranged' into the so-called Kyiv culture , whilst the westernmost areas were integrated into the Wielbark culture . Wheat Wheat is a grass widely cultivated for its seed , a cereal grain that is a staple food around the world. The many species of wheat together make up the genus Triticum ( / ˈ t r ɪ t ɪ k ə m / );

4136-536: The Chernyakhov culture and the Wielbark culture , which was located closer to the Baltic Sea . The Chernyakhov culture encompassed regions of modern Ukraine, Moldova, and Romania. The spelling Chernyakhov is the transliteration from Russian for an archaeological site in the vicinity of Kyiv , modern Ukraine. Other spellings include Cherniakhiv ( Ukrainian ), Czerniachów ( Polish ), and several others. The culture has also been named after Sântana de Mureș ,

4224-408: The Chernyakhov culture with the federation of the Goths. However, the remains of archaeologically visible material culture and their link with ethnic identity are not as clear as originally thought. Today, scholars recognize the Chernyakhov zone as representing a cultural interaction of a diversity of peoples, but predominantly those who already existed in the region, whether it be the Sarmatians , or

4312-484: The Goths' domination of the Pontic area. He cites literary sources that attest that the Goths were the centre of political attention at this time. In particular, the culture's development corresponds well with Jordanes ' tale of Gothic migration from Gothiscandza to Oium , under the leadership of Filimer . Moreover, he highlights that crucial external influences that catalysed Chernyakhov cultural development derived from

4400-467: The culture, and local smiths produced much of the implements, although there is some evidence of production specialization. The Chernyakhov culture ends in the 5th century, attributed to the arrival of the Huns. The collapse of the culture is no longer explained in terms of population displacement, although there was an outmigration of Goths. Around 370, a series of events including the presence of Huns at

4488-414: The deepest of arable crops, extending as far down as 2 metres (6 ft 7 in). While the roots of a wheat plant are growing, the plant also accumulates an energy store in its stem, in the form of fructans , which helps the plant to yield under drought and disease pressure, but it has been observed that there is a trade-off between root growth and stem non-structural carbohydrate reserves. Root growth

4576-485: The domestic form comes after c.   8800 BC in southern Turkey, at Çayönü , Cafer Höyük , and possibly Nevalı Çori . Genetic evidence indicates that it was domesticated in multiple places independently. Wild emmer wheat ( T. turgidum subsp. dicoccoides ) is less widespread than einkorn, favouring the rocky basaltic and limestone soils found in the hilly flanks of the Fertile Crescent. It

4664-766: The earliest known wheat with sufficient gluten for yeasted breads was found in a granary at Assiros in Macedonia dated to 1350 BC. From the Middle East , wheat continued to spread across Europe and to the Americas in the Columbian exchange . In the British Isles, wheat straw ( thatch ) was used for roofing in the Bronze Age , and remained in common use until the late 19th century. White wheat bread

4752-495: The east Carpathian/ Podolia region, as well as, to a lesser extent, north into the forest zone are also evident. The movement of Zarubintsy groups has been linked to an increasingly arid climate, whereby the population left the hillforts on high promontories and moved southward into river valleys. This mostly southern movement brought them closer to westward moving Sarmatian groups (from the Don region) and Thracian - Celtic elements. By

4840-438: The eastern edge of the culture culminated with the death of Ermanaric , the leader of Gothic confederation , and his successor, Athanaric , found refuge south of Danube along with most of the Gothic population. Rather, more recent theories explain the collapse of the Chernyakhov culture in terms of a disruption of the hierarchical political structure that maintained it. John Mathews suggests that, despite its cultural homogeneity,

4928-534: The ethnic affinity of people in the Chernyakhov zone. Soviet scholars, such as Boris Rybakov , saw it as the archaeological reflection of the Proto-Slavs , but western, especially German, historians, and Polish archeologists attributed it to the Goths. According to Kazimierz Godłowski (1979), the origins of Slavic culture should be connected with the areas of the upper Dnieper River basin (the Kyiv culture ) while

5016-567: The farm and because of poor roads, inadequate storage technologies, inefficient supply chains and farmers' inability to bring the produce into retail markets dominated by small shopkeepers. Some 10% of total wheat production is lost at farm level, another 10% is lost because of poor storage and road networks, and additional amounts are lost at the retail level. In the Punjab region of the Indian subcontinent, as well as North China, irrigation has been

5104-456: The farmer have a detailed understanding of each stage of development in the growing plants. In particular, spring fertilizers , herbicides , fungicides , and growth regulators are typically applied only at specific stages of plant development. For example, it is currently recommended that the second application of nitrogen is best done when the ear (not visible at this stage) is about 1 cm in size (Z31 on Zadoks scale ). Knowledge of stages

5192-601: The glumes are fragile and the rachis tough. On threshing, the chaff breaks up, releasing the grains. Wheat grain classes are named by colour, season, and hardness. The classes used in the United States are: Wheat is a staple cereal worldwide. Raw wheat berries can be ground into flour or, using hard durum wheat only, can be ground into semolina ; germinated and dried creating malt ; crushed or cut into cracked wheat; parboiled (or steamed), dried, crushed and de-branned into bulgur also known as groats . If

5280-431: The glumes. The flowers are grouped into spikelets , each with between two and six flowers. Each fertilised carpel develops into a wheat grain or berry; botanically a fruit , it is often called a seed. The grains ripen to a golden yellow; a head of grain is called an ear. Leaves emerge from the shoot apical meristem in a telescoping fashion until the transition to reproduction i.e. flowering. The last leaf produced by

5368-562: The grains of wild grasses led to the creation of domestic strains, as mutant forms ('sports') of wheat were more amenable to cultivation. In domesticated wheat, grains are larger, and the seeds (inside the spikelets ) remain attached to the ear by a toughened rachis during harvesting. In wild strains, a more fragile rachis allows the ear to shatter easily, dispersing the spikelets. Selection for larger grains and non-shattering heads by farmers might not have been deliberately intended, but simply have occurred because these traits made gathering

5456-479: The grains, and (in domesticated wheats) a semi-brittle rachis that breaks easily on threshing. The result is that when threshed, the wheat ear breaks up into spikelets. To obtain the grain, further processing, such as milling or pounding, is needed to remove the hulls or husks. Hulled wheats are often stored as spikelets because the toughened glumes give good protection against pests of stored grain. In free-threshing (or naked) forms, such as durum wheat and common wheat,

5544-519: The late 1840s. By 1879, Saskatchewan was the center, followed by Alberta , Manitoba and Ontario , as the spread of railway lines allowed easy exports to Britain. By 1910, wheat made up 22% of Canada's exports, rising to 25% in 1930 despite the sharp decline in prices during the worldwide Great Depression . Efforts to expand wheat production in South Africa, Kenya and India were stymied by low yields and disease. However, by 2000 India had become

5632-420: The main drivers of wheat output growth in the second half of the century. There were some significant decreases in wheat crop area, for instance in North America. Better seed storage and germination ability (and hence a smaller requirement to retain harvested crop for next year's seed) is another 20th-century technological innovation. In Medieval England, farmers saved one-quarter of their wheat harvest as seed for

5720-442: The middle of the 21st century. Global demand for wheat is increasing because of the usefulness of gluten to the food industry. Wheat is an important source of carbohydrates . Globally, it is the leading source of vegetable proteins in human food, having a protein content of about 13%, which is relatively high compared to other major cereals but relatively low in protein quality (supplying essential amino acids ). When eaten as

5808-586: The most "western" range of variation among the groups of this study", with 64.8% of Yamnaya -like ancestry, "lacking the Altaian component entirely" and having "higher proportion" of Central European Middle Neolithic ancestry (35.2%) than historically earlier samples from the region. They suggest the culture was a multi-ethnic mix, but the samples "appear to represent its Gothic component". Their mtDNA haplogroups were H1n6, H1c and T2g1. Zarubintsy culture The Zarubintsy , Zarubyntsi or Zarubinets culture

5896-469: The most widely grown is common wheat ( T. aestivum ). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC. Botanically, the wheat kernel is a caryopsis , a type of fruit . Wheat is grown on a larger area of land than any other food crop (220.7 million hectares or 545 million acres in 2021). World trade in wheat

5984-568: The most widely used. Each scale is a standard system which describes successive stages reached by the crop during the agricultural season. For example, the stage of pollen formation from the mother cell, and the stages between anthesis and maturity, are susceptible to high temperatures, and this adverse effect is made worse by water stress. Technological advances in soil preparation and seed placement at planting time, use of crop rotation and fertilizers to improve plant growth, and advances in harvesting methods have all combined to promote wheat as

6072-488: The need to systematically remove vegetation or till the soil. They may also have exploited natural wetlands and floodplains to practice décrue farming , sowing seeds in the soil left behind by receding floodwater. It was harvested with stone-bladed sickles . The ease of storing wheat and other cereals led farming households to become gradually more reliant on it over time, especially after they developed individual storage facilities that were large enough to hold more than

6160-473: The next crop, leaving only three-quarters for food and feed consumption. By 1999, the global average seed use of wheat was about 6% of output. In the 21st century, rising temperatures associated with global warming are reducing wheat yield in several locations. Wheat is an annual crop. It can be planted in autumn and harvested in early summer as winter wheat in climates that are not too severe, or planted in spring and harvested in autumn as spring wheat. It

6248-426: The presence of Germanic groups. The Chernyakhov people were primarily a settled population involved in cultivation of cereals – especially wheat , barley and millet . Finds of ploughshares, sickles and scythes have been frequent. Cattle breeding was the primary mode of animal husbandry, and the breeding of horses appears to have been restricted to the open steppe. Metalworking skills were widespread throughout

6336-461: The raw wheat is broken into parts at the mill, as is usually done, the outer husk or bran can be used in several ways. Wheat is a major ingredient in such foods as bread , porridge , crackers , biscuits , muesli , pancakes , pasta , pies , pastries , pizza , semolina , cakes , cookies , muffins , rolls , doughnuts , gravy , beer , vodka , boza (a fermented beverage ), and breakfast cereals . In manufacturing wheat products, gluten

6424-452: The right moment to harvest. Harvesting involves reaping , cutting the stems to gather the crop; and threshing , breaking the ears to release the grain; both steps are carried out by a combine harvester . The grain is then dried so that it can be stored safe from mould fungi. Wheat normally needs between 110 and 130 days between sowing and harvest, depending upon climate, seed type, and soil conditions. Optimal crop management requires that

6512-517: The second largest producer of wheat in the world. In the 19th century the American wheat frontier moved rapidly westward. By the 1880s 70% of American exports went to British ports. The first successful grain elevator was built in Buffalo in 1842. The cost of transport fell rapidly. In 1869 it cost 37 cents to transport a bushel of wheat from Chicago to Liverpool . In 1905 it was 10 cents. In

6600-513: The seeds easier; nevertheless such 'incidental' selection was an important part of crop domestication . As the traits that improve wheat as a food source involve the loss of the plant's natural seed dispersal mechanisms, highly domesticated strains of wheat cannot survive in the wild. Wild einkorn wheat ( T. monococcum subsp. boeoticum ) grows across Southwest Asia in open parkland and steppe environments. It comprises three distinct races , only one of which, native to Southeast Anatolia ,

6688-417: The stem, one above each joint. At the top of the stem is the flower head, containing some 20 to 100 flowers. Each flower contains both male and female parts. The flowers are wind-pollinated , with over 99% of pollination events being self-pollinations and the rest cross-pollinations . The flower is housed in a pair of small leaflike glumes . The two (male) stamens and (female) stigmas protrude outside

6776-405: The temperature at or near freezing, its dormancy then being broken by the thaw or rise in temperature. Spring wheat does not undergo dormancy. Wheat requires a deep soil , preferably a loam with organic matter, and available minerals including soil nitrogen, phosphorus, and potassium. An acid and peaty soil is not suitable. Wheat needs some 30 to 38 cm of rain in the growing season to form

6864-407: The upper ( adaxial ) side of the leaf, than on the under ( abaxial ) side. It has been theorised that this might be an effect of it having been domesticated and cultivated longer than any other plant. Winter wheat generally produces up to 15 leaves per shoot and spring wheat up to 9 and winter crops may have up to 35 tillers (shoots) per plant (depending on cultivar). Wheat roots are among

6952-614: The use of threshing machines , and progressing to large and costly machines like the combine harvester which greatly increased productivity. At the same time, better varieties such as Norin 10 wheat , developed in Japan in the 1930s, or the dwarf wheat developed by Norman Borlaug in the Green Revolution , greatly increased yields. In addition to gaps in farming system technology and knowledge, some large wheat grain-producing countries have significant losses after harvest at

7040-542: The use of the oven and developed baking into one of the first large-scale food production industries." By 4000 BC, wheat had reached the British Isles and Scandinavia . Wheat likely appeared in China 's lower Yellow River around 2600 BC. The oldest evidence for hexaploid wheat has been confirmed through DNA analysis of wheat seeds, dating to around 6400–6200 BC, recovered from Çatalhöyük . As of 2023,

7128-486: Was 808.4 million tonnes, led by China, India, and Russia which collectively provided 43.22% of the world total. As of 2019 , the largest exporters were Russia (32 million tonnes), United States (27), Canada (23) and France (20), while the largest importers were Indonesia (11 million tonnes), Egypt (10.4) and Turkey (10.0). In 2021, wheat was grown on 220.7 million hectares or 545 million acres worldwide, more than any other food crop. World trade in wheat

7216-727: Was a culture that, from the 3rd century BC until the 1st century AD, flourished in the area north of the Black Sea along the upper and middle Dnieper and Pripyat Rivers , stretching west towards the Southern Bug river. Zarubintsy sites were particularly dense between the Rivers Desna and Ros as well as along the Pripyat river. It was identified around 1899 by the Czech-Ukrainian archaeologist Vikentiy Khvoyka and

7304-462: Was domesticated in southeastern Anatolia, but only once. The earliest secure archaeological evidence for domestic emmer comes from Çayönü, c.  8300–7600 BC , where distinctive scars on the spikelets indicated that they came from a hulled domestic variety. Slightly earlier finds have been reported from Tell Aswad in Syria, c.  8500–8200 BC , but these were identified using

7392-429: Was domesticated. The main feature that distinguishes domestic einkorn from wild is that its ears do not shatter without pressure, making it dependent on humans for dispersal and reproduction. It also tends to have wider grains. Wild einkorn was collected at sites such as Tell Abu Hureyra ( c.  10,700–9000 BC ) and Mureybet ( c.  9800–9300 BC ), but the earliest archaeological evidence for

7480-601: Was historically a high status food, but during the nineteenth century it became in Britain an item of mass consumption, displacing oats , barley and rye from diets in the North of the country. It became "a sign of a high degree of culture". After 1860, the enormous expansion of wheat production in the United States flooded the world market, lowering prices by 40%, and (along with the expansion of potato growing) made

7568-452: Was made of finer clay. It was reminiscent of earlier Sarmatian types, refined by Roman and La Tene influences. Hand made pottery showed a greater variety in form, and was sometimes decorated with incised linear motifs. In addition, Roman amphorae are also found, suggesting trade contacts with the Roman world. There is also a small, but regular, presence of distinct hand–made pottery typical of that found in western Germanic groups, suggesting

7656-494: Was rather accomplished by a series of small, sometimes mutually antagonistic groups. However, Guy Halsall challenges some of Heather's conclusions. He sees no chronological development from the Wielbark to Chernyakhov culture, given that the latter stage of the Wielbark culture is synchronous with Chernyakhov, and the two regions have minimal territorial overlap. "Although it is often claimed that Cernjachov metalwork derives from Wielbark types, close examination reveals no more than

7744-456: Was relatively uncommon for the first thousand years of the Neolithic (when barley predominated), but became a staple after around 8500 BC. Early wheat cultivation did not demand much labour. Initially, farmers took advantage of wheat's ability to establish itself in annual grasslands by enclosing fields against grazing animals and re-sowing stands after they had been harvested, without
