186-438: 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
279-535: 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
372-409: 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
465-434: 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 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
558-470: 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
651-681: 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 )
744-450: 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
837-475: 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

The total length of automobile roads with hard surface
1302-426: 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
1395-506: 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

It has long narrow leaves, their bases sheathing 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
2232-400: 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
2325-459: 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
2418-402: 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
2511-461: Is considered that Kaluga was established as a frontier settlement to protect the Moscow principality from Lithuania's attacks. Around half of the current province with the western and southern parts and the towns of Kozelsk , Mosalsk , Meshchovsk , Serpeysk , Peremyshl and Vorotynsk were part of Lithuania in the late 14th-15th centuries. Between 1480–1481, Kaluga's territory was the place of
2604-418: 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
2697-473: 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
2790-629: 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,

2976-458: 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
3069-399: 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
3162-511: 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

There are several successful eco-settlements: the nature reserve Kaluzhskiye Zaseki, the Ugra National Park , the Tarusa natural reserve, and
6045-562: 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
6138-479: 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,

The first mentions of Kaluga's towns are associated with events in the 12th century, specifically, the feudal war between the Olegovichi and the Monomakhovichi (Kozelsk — 1146, Serensk — 1147, Vorotynsk — 1155, Mosalsk — 1231). In the 14th century, Kaluga lands were places of constant confrontations between Lithuania and Moscow . Traditionally, it
6324-519: 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
6417-483: 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
6510-568: 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
6603-488: 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
6696-473: 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
6789-405: The oblast is exposed to a substantial amount of solar radiation — around 115 Kcal per cm . The average annual air temperature varies from 3.5–4.0 °C (38.3–39.2 °F) in the north and the north-east to up to 4.0–4.6 °C (39.2–40.3 °F) in the west and the east of the oblast. The duration of the frost-free season is 113 to 127 days. The northern part of the oblast is the coldest, while
6882-543: The oblast is sometimes visited by bison that were recently released into the Orlovskoye Polesye national park. Aquatic fauna includes two kinds of lamprey and 41 species of bony fish . The diversity of fish is explained by the variety of habitats. Among 11 kinds of amphibians, the most common are crested and common newts , red-bellied, common and green toads , and various lake, pool, moor and grass frogs . Reptiles are represented by 7 species, including snakes:
6975-580: 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 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
7068-476: The province's industry is the automotive complex. The main regional transport hubs are located in Kaluga , Obninsk , and Sukhinichi . M3 "Ukraine" is the main automobile highway, with a traffic density of up to 13,800 vehicles/day, which passes through the towns of Balabanovo, Obninsk, Maloyaroslavets, Kaluga, Sukhinichi, and Zhizdra. An equally important role is played by Moscow – Warsaw federal highway, with
7161-461: 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
7254-521: The regular events that are organized for tourists: As early as the 16th century, Kaluga was a major commercial port acting as a connecting link between Lithuania and Moscow. Back then, the city exported wooden utensils known far beyond the provincial boundaries. Starting in the 1680s, stone churches were built on the sites of wooden churches. By the latter half of the 18th century, there were 183 stone and 2235 wooden buildings in Kaluga. The 17th-century Korobov mansion with its semidomes and patterned cornices
7347-399: The rest cross-pollinations . The flower is housed in a pair of small leaflike glumes . The two (male) stamens and (female) stigmas protrude outside 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;
7440-452: 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
7533-517: 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
7626-513: 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 ,
7719-654: The southeast), the Smolensk–Moscow Upland , and the Dnieper – Desna watershed. Most of the oblast is occupied by plains, fields, and forests with diverse flora and fauna. The administrative center is located on the Baryatino-Sukhinichy plain. The western part of the oblast — located within the drift plain — is dominated by the Spas-Demensk ridge. To the south is an outwash plain that is part of
7812-405: 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
7905-614: 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
7998-542: 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,
8091-805: The venomous adder and the harmless water snake and smooth snake . There are 267 types of birds registered as visiting the oblast, including 177 to nest, 58 to migrate and 32 to occasionally transit. The most significant bird-of-prey habitats are located in the Kaluzhskiye Zaseki Nature Reserve and the interfluve of the Vytebet and the Resseta . The largest populations are: waterfowl - mallard ; semi-aquatic – black-headed gull ; in forest – chaffinch , chiffchaff ; along river banks – sand martin ; in settlements – feral pigeon , common swift , rook , tree sparrow . According to
8184-455: 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 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
8277-486: 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
8370-462: 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
8463-429: 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
8556-601: 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
8649-456: 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
