Rye, town (1991 pop. 4,127), East Sussex, SE England, on the Rother River. It is a tourist resort and small port with boatbuilding and netmaking industries. Rye was one of the "ancient towns" added to the Cinque Ports. It had a thriving trade in the 17th cent. but decayed after the recession of the sea early in the 19th cent. There are remains of an ancient friary, a large Norman and Early English church, the 12th-century Ypres Tower, and the Thomas Peacocke school (1636). The dramatist John Fletcher was born in Rye.

Rye, city (1990 pop. 14,936), Westchester co., SE N.Y., a suburb of New York City, on Long Island Sound; settled 1660, inc. as a city 1942. It is chiefly residential, with a cancer-research center, a hardware and locks manufacturing company, and several corporate offices. In colonial times, Rye was the first stop on the Boston Post Road after New York City. The old Square House, an inn where many Revolutionary notables stayed, is now a museum. Playland, a large county-owned amusement park, is on the beach there. Chief Justice John Jay is buried in Rye.

rye, cereal grain of the family Gramineae (grass family). The grain, Secale cereale, is important chiefly in Central and N Europe. It seems to have been domesticated later than wheat and other staple grains; cultivated rye is quite similar to the wild forms and no traces of it have been found among Egyptian ruins or Swiss lake dwellings. Where it grows well, wheat is preferred, but rye will produce a good crop on soil too poor or in a climate too cool to produce a good crop of wheat. The standard schwarzbrot, or pumpernickel, of Europe was formerly the major rye product. A bread of lighter color, called rye bread, is made of rye flour mixed with wheat flour. Today rye is used mostly as a stock feed (usually mixed with other grains), for hay and pasturage, for green manure, and as a cover crop. Russia leads in world production. Rye is much used as a distillers' grain in making whisky and gin. The tough straw of rye is valued for many purposes, e.g., thatching for roofs and stuffing for horse collars. Ergot is a fungus disease of rye; the fungus is poisonous and may make the rye unsafe to use. Wild rye and lyme grass are names for several grasses of the genus Elymus, some of which are occasionally planted as ornamentals or used for binding sand. Rye is classified in the division Magnoliophyta, class Liliatae, order Cyperales, family Gramineae.

Rye (Secale cereale) is a grass grown extensively as a grain and forage crop. It is a member of the wheat tribe (Triticeae) and is closely related to barley and wheat. Rye grain is used for flour, rye bread, rye beer, some whiskies, some vodkas, and animal fodder. It can also be eaten whole, either as boiled rye berries, or by being rolled, similar to rolled oats.

Rye is a cereal and should not be confused with ryegrass which is used for lawns, pasture, and hay for livestock.

History

Rye is one of a number of species that grow wild in central and eastern Turkey, and adjacent areas. Domesticated rye occurs in small quantities at a number of Neolithic sites in Turkey, such as PPNB Can Hasan III, but is otherwise virtually absent from the archaeological record until the Bronze Age of central Europe, c. 1800-1500 BC. It is possible that rye travelled west from Turkey as a minor admixture in wheat, and was only later cultivated in its own right. Although archeological evidence of this grain has been found in Roman contexts along the Rhine Danube and in the British Isles, Pliny the Elder is dismissive of rye, writing that it "is a very poor food and only serves to avert starvation" and wheat is mixed into it "to mitigate its bitter taste, and even then is most unpleasant to the stomach" (N.H. 18.40).

Since the Middle Ages, rye has been widely cultivated in Central and Eastern Europe and is the main bread cereal in most areas east of the French-German border and north of Hungary.

Claims of much earlier cultivation of rye, at the Epipalaeolithic site of Tell Abu Hureyra in the Euphrates valley of northern Syria, remain controversial. Critics point to inconsistencies in the radiocarbon dates, and identifications based solely on grain, rather than on chaff.

Agronomy

Winter rye is any breed of rye planted in the fall to provide ground cover for the winter. It actually grows during any warmer days of the winter, when sunlight temporarily brings the plant to above freezing, even while there is still general snow cover. It can be used to prevent the growth of winter-hardy weeds, and can either be harvested as a bonus crop, or tilled directly into the ground in spring to provide more organic matter for the next summer's crop. It is sometimes used in winter gardens and is a very common nurse crop.

The flame moth, rustic shoulder-knot and turnip moth are among the species of Lepidoptera whose larvae feed on rye.

Rye is grown primarily in Eastern, Central and Northern Europe. Main rye belt stretches from northern Germany through Poland, Ukraine, Belarus, Lithuania and Latvia into central and northern Russia. Rye is also grown in North America (Canada and the USA), in South America (Argentina), in Turkey, in Kazakstan and in northern China.

Production levels of rye are falling in most of the producing nations due to falling demand. For instance, production of rye in Russia fell from 13.9 million tons in 1992 to just 3.4 Mt in 2005. Corresponding figures for other countries are as follows: Poland - 5.9 Mt in 1992 and 3.4 Mt in 2005; Germany - 3.3 Mt & 2.8 Mt; Belarus - 3.1 Mt & 1.2 Mt; China - 1.7 Mt & 0.6 Mt; Kazakhstan - 0.6 Mt & 0.02 Mt.

Most of rye is consumed locally, and is exported only to neighbouring countries, but not worldwide.

Diseases

Rye is highly susceptible to the ergot fungus. Consumption of ergot-infected rye by humans and animals results in a serious medical condition known as ergotism. Ergotism can cause both physical and mental harm, including convulsions, miscarriage, necrosis of digits, and hallucinations. Historically, damp northern countries that have depended on rye as a staple crop were subject to periodic epidemics of this condition. There have been "occurrence[s] of ergotism with periods where there were high incidents of people persecuted for being witches. Emphasis was placed on the Salem witch trials in Massachusetts in 1692, where there was a sudden rise in the number of people accused of being witches, but earlier examples were taken from Europe, as well.

Uses

Rye bread, including pumpernickel, is a widely eaten food in Northern and Eastern Europe. Rye is also used to make the familiar crisp bread. Rye flour has a lower gluten content than wheat flour, and contains a higher proportion of soluble fiber.

Some other uses of rye include rye whiskey and use as an alternative medicine in a liquid form, known as rye extract. Often marketed as Oralmat, rye extract is a liquid obtained from rye and similar to that extracted from wheatgrass. Its benefits are said to include a strengthened immune system, increased energy levels and relief from allergies, but there is no clinical evidence for its efficacy.

Rye straw is used to make corn dollies.
