Fillyploppy or whatever your name is, cite your references! I will report you.

Wheat is indeed from Iraq/Iran.

Sunflowers were originally domesticated in North America.

According to Wikipedia alfalfa is found wild in Iran and probably came from there.

Answer 3

Wheat and barley were the first cereals known to have been domesticated. Wheat originated in Southwest Asia in the area known as the Fertile Crescent. The genetic relationships between einkorn and emmer indicate that the most likely site of domestication is near Diyarbakir in Turkey [9]. These wild wheats were domesticated as part of the origins of agriculture in the Fertile Crescent. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the domestication of wheat through selection of mutant forms with tough ears which remained intact during harvesting, larger grains, and a tendency for the spikelets to stay on the stalk until harvested [10]. Because of the loss of seed dispersal mechanisms, domesticated wheats have limited capacity to propagate in the wild.[11]

The cultivation of wheat began to spread beyond the Fertile Crescent during the Neolithic period. By 5,000 years ago, wheat had reached Ethiopia, India, Ireland and Spain. A millennium later it reached China.[11] Agricultural cultivation using horse collar leveraged plows (3000 years ago) increased cereal grain productivity yields, as did the use of seed drills which replaced broadcasting sowing of seed in the 18th century. Yields of wheat continued to increase, as new land came under cultivation and with improved agricultural husbandry involving the use of fertilizers, threshing machines and reaping machines (the 'combine harvester'), tractor-drawn cultivators and planters, and better varieties (see green revolution and Norin 10 wheat). With population growth rates falling, while yields continue to rise, the acreage devoted to wheat may now begin to decline for the first time in modern human history.[12] But now in 2007 wheat stocks have reached their lowest since 1981 and 2006 was the first year in which the world consumed more wheat than the world produced - a gap that is continuously widening as the requirement for wheat increases beyond production. The use of wheat as a bio-fuel will exacerbate the situation.

Sunflowers are native to the Americas. There is some debate about where the sunflower was first domesticated. The earliest known examples of a fully domesticated sunflower were found at the Hayes site in Tennessee and date back to around 2300 B.C. There were also other remains found at the Olmec site of San Andrés dating some time before 2100 B.C. The Incas used the sunflower as an image of their sun god. Gold images of the flower, as well as seeds, were taken back to Europe early in the 16th century.

The Giant sunflower (Helianthus giganteus) is native to the Eastern United States. They can grow to be between 3 and 12 feet tall. They can grow from Ontario to Minnesota and Kentucky to Georgia. Their flower heads can be between 2 to 3 inches wide. They are most commonly found in valleys with wet meadows or swamps. The Giant sunflower grows between July and October.

To grow well, sunflowers need full sun. They grow best in fertile, moist, well-drained soil with a lot of mulch. In commercial planting, seeds are planted 45 cm (1.5') apart and 2.5 cm (1") deep.

Sunflower "whole seed" (fruit) are sold as a snack food after roasting within heated ovens with or without salt added. Sunflowers can be processed into a peanut butter alternative, Sunbutter, especially in China, Russia, the United States, the Middle East and Europe. It is also sold as food for birds and can be used directly in cooking and salads.

Sunflower oil, extracted from the seeds, is used for cooking, as a carrier oil and to produce biodiesel, for which it is less expensive than the olive product. A range of sunflower varieties exist with differing fatty acid compositions; some 'high oleic' types contain a higher level of healthy monounsaturated fats in their oil than even olive oil.

During the 18th Century, the use of sunflower oil became very popular in Europe, particularly with members of the Russian Orthodox Church because sunflower oil was one of the few oils that was not prohibited during Lent.

The cake remaining after the seeds have been processed for oil is used as a livestock feed. Some recently developed cultivars have drooping heads. These cultivars are less attractive to gardeners growing the flowers as ornamental plants, but appeal to farmers, because they reduce bird damage and losses from some plant diseases. Sunflowers also produce latex and are the subject of experiments to improve their suitability as an alternative crop for producing hypoallergenic rubber.

For farmers not intending to grow it, the sunflower is considered a noxious weed. The wild variety will grow unwanted in corn and soybean fields which can have a negative impact on yields.

Alfalfa (Medicago sativa), also known as Lucerne, Purple Medic and Trefoil (Arabic: البرسيم الحجازي), is a perennial flowering plant cultivated as an important forage crop.

Alfalfa is one of the most important legumes used in agriculture. The US is the largest alfalfa producer in the world. The leading alfalfa growing states (within the U.S.A.) are California, South Dakota, and Wisconsin. The upper Midwestern states account for about 50% of US production, the North eastern states 10%, and western states 40% of US production, the latter mostly under irrigation. Alfalfa is not very important in the Southeastern states. However, alfalfa has a wide range of adaptation and can be grown from very cold northern plains to high mountain valleys, from rich temperate agricultural regions to Mediterranean climates and searing hot deserts.

Alfalfa lives from three to twelve years, depending on variety and climate. It is a cool season perennial legume, growing to a height of 1 meter. It resembles clover with clusters of small purple flowers. It also has a deep root system sometimes stretching to 4.5 metres. This makes it very resilient, especially to droughts. It has a tetraploid genome.

Alfalfa is native to Iran, where it was probably domesticated during the Bronze Age to feed horses being brought from Central Asia. It came to Greece around 490 B.C. being used as a horse feed for Persian army. It was introduced from Chile to the United States around 1860. It is widely grown throughout the world as forage for cattle, and is most often harvested as hay. Alfalfa has the highest feeding value of all common hay crops, being used less frequently as pasture. Like other legumes, its root nodules contain bacteria, like Rhizobium, with the ability to fix nitrogen, producing a high-protein feed regardless of available nitrogen in the soil.

Its wide cultivation beginning in the seventeenth century was an important advance in European agriculture. Its symbiotic relationship with nitrogen-fixing bacteria and use as animal feed greatly improved agricultural efficiency. When grown on soils where it is well-adapted, alfalfa is the highest yielding forage plant.

Alfalfa is a plant that exhibits autotoxicity, which means that it is difficult for alfalfa seed to grow in existing stands of alfalfa. Therefore, it is recommended that alfalfa fields be cleared or rotated before reseeding.

Its primary use is for dairy production, followed by beef, sheep, horses and goats, but it is sometimes used for human consumption. Alfalfa sprouts are used as a salad ingredient in the United States, Australia and New Zealand. Tender shoots are eaten in some places as a leaf vegetable. Human consumption of older plant parts is limited primarily by very high fiber content. Dehydrated alfalfa leaf is commercially available as a dietary supplement in several forms, such as tablets, powders and tea. Alfalfa is believed to be a galactagogue.
