Barley



Barley (''Hordeum vulgare'') is a major food and animal feed crop, a member of the grass family Poaceae. Barley is the fifth largest cultivated cereal crop in the world (530,000 km² or 132 million acres). Its germination time is anywhere from 1-3 days. == History == Cultivated barley is descended from Hordeum (''Hordeum spontaneum''), which still can be found in the Middle East. Both luder forms are diploid (2n=14 chromosomes). All variants of barley produce viable seed when crossed and are thus considered to belong to one and the same species today. The major difference between wild and domesticated barley is the brittle rachis of the former, which is conductive to self-propagation. The earliest finds of barley come from Epi-Paleolithic sites the Levant, beginning in the Natufian. The first domesticated barley has been found in the aceramic neolithic layers (PPN B) of Tell Abu Hureyra in Syria. The domestication seems to be contemporaneous to that of wheat. Barley, seen as an ancient and central gift of the earth, had ritual significance, probably from the earliest stages of the Eleusinian Mysteries. The preparatory ''kykeon'' or mixed drink of the initiates, prepared from barley and herbs, was referred to in the Homeric hymn to Demeter, who was also called "Barley-mother". Greek practice was to dry the barley groats and roast them before preparing the porridge, according to Pliny's ''Natural History'' (xviii.72). This produces a malt that soon ferments and becomes slightly alcoholic. ==Cultivars== Barley may be divided into two major cultivar, fall and spring, to which may be added a bastard variety called bear or bigg, which affords similar nutriment or substance, though of inferior quality. The spring is cultivated like oats; the fall, like fall wheat. Early barley, under various names, was formerly sown in Britain upon lands that had been previously summer-fallowed, or were in high condition. The most proper seed season for spring barley is any time in March or April, though good crops have been produced by seeds sown at a much later period. Barley can be divided by the number of kernal rows in the head. Three species have been cultivated; two-row barley (''Hordeum distichum''), four-row (''Hordeum tetrastichum'' L. and six-row barley (''Hordeum vulgare'') according to the traditional terminology. In two-row barley only one flower is fertile, two in the four-row variety, in the six-row variety all three; modern barley growing largely uses ''H. vulgare''. Two-row barley is the oldest form, wild barley having two rows as well. Two-row barley has a lower protein content than six-row barley but a higher enzyme content. High protein barley is best suited for animal feed or malt that has a large adjunct content. Two-row barley is best suited for pure malts. Four-row is unsuitable for brewing. There are naked and hulled barleys, the hulled barleys being the older forms. Barley is widely adaptable and is currently a major crop of the temperate and tropical areas. ==Production== Major barley producers are :
Russia 72,000 km²
Canada 45,000 km²
Ukraine 37,000 km²
Turkey 36,000 km²
Spain 33,000 km²
Australia 30,000 km²
Morocco 23,000 km²
USA 21,000 km²
Iraq 12,000 km²
Iran 10,000 km²
==Uses== Barley is a staple food for humans and other animals. It is more tolerant of salts than wheat, which might explain the increase of barley cultivation on Mesopotamia from the 2nd Millennium BC onwards. Barley can still thrive in conditions that are too cold even for rye. Malting barley is a key ingredient in beer and whiskey production. The 1881 ''Household Cyclopedia'' adds:
Next to wheat the most valuable grain is barley, especially on light and sharp soils. It is a tender grain and easily hurt in any of the stages of its growth, particularly at seed time; a heavy shower of rain will then almost ruin a crop on the best prepared land; and in all the after processes greater pains and attention are required to ensure success than in the case of other grains. The harvest process is difficult, and often attended with danger; even the threshing of it is not easily executed with machines, because the awn generally adheres to the grain, and renders separation from the straw a troublesome task. Barley, in fact, is raised at greater expense than wheat, and generally speaking is a more hazardous crop. Except upon rich and genial soils, where climate will allow wheat to be perfectly reared, it ought not to be cultivated.

Preparation of ground

Barley is chiefly taken after turnips, sometimes after peas and beans, but rarely by good farmers either after wheat or oats, unless under special circumstances. When sown after turnips it is generally taken with one furrow, which is given as fast as the turnips are consumed, the ground thus receiving much benefit from the spring frosts. But often two, or more furrows are necessary for the fields last consumed, because when a spring drought sets in, the surface, from being poached by the removal or consumption of the crop, gets so hardened as to render a greater quantity of ploughing, harrowing and rolling necessary than would otherwise be called for. When sown after beans and peas, one winter and one spring ploughing are usually bestowed: but when after wheat or oats, three ploughings are necessary, so that the ground may be put in proper condition. These operations are very ticklish in a wet and backward season, and rarely in that case is the grower paid for the expense of his labor. Where land is in such a situation as to require three ploughings before it can be seeded with barley, it is better to summer-fallow it at once than to run the risks which seldom fail to accompany a quantity of spring labor. If the weather be dry, moisture is lost during the different processes, and an imperfect braird necessarily follows; if it be wet the benefit of ploughing is lost, and all the evils of a wet seed time are sustained by the future crop.

The quantity sown is different in different cases, according to the quality of the soil and other circumstances. Upon very rich lands eight pecks per acre [110 kg/ha] are sometimes sown; twelve [160 kg/ha] is very common, and upon poor land more is sometimes given.

By good judges a quantity of seed is sown sufficient to ensure a full crop, without depending on its sending out offsets; indeed, where that is done few offsets are produced, the crop grows and ripens equally, and the grain is uniformly good.

Barley



"a malt that soon ferments and become slightly alcoholic." Isn't malt germinated grain that has been roasted? You would need some sugar to get alcohol. --User:Yak 08:57, 26 Aug 2004 (UTC) ::I've never made beer. Does one add sugar? User:Wetman 09:02, 26 Aug 2004 (UTC) :::no. In the germination process, the starch of the grain is changed into maltose, a form of sugar, and that is changed into alcohol during fermentation. Ungerminated grain only contains starch, no sugar. --User:Yak 09:09, 26 Aug 2004 (UTC) ---- From the language, it appears certain that it wasn't just one paragraph quoted from the 1881 book, but the next three as well. I have assumed that to be so, and made the following changes *moved the blockquote down *changed Wiki header to html header *enclosed conversion in brackets and rounded them appropriately, on assumption that they were not in original I did not check earier edits to see if changes have been made in the quoted material. This should not be edited freely; snipping and ellipsis marks might be approriate. User:Gene Nygaard 13:16, 13 Dec 2004 (UTC) ---- What is "braird" supposed to be in that quote? User:Gene Nygaard 13:28, 13 Dec 2004 (UTC) ---- And what is 'luder' in the History section?
