=Timothy= (_Phleum pratense_) is a popular and most widely used hay plant in America, and also extensively seeded with other grasses for pasture, prospering best in moist loams. It yields the year following its sowing, grows from one and a half to four feet high, and twelve to fifteen pounds of seed are sown per acre. The chief timothy region is the northern half of the United States, east of the 100th meridian, where it is usually sown in the fall with winter wheat, or in the spring with oats. Forty-five pounds of seed make a bushel.
=Wheat= (_Triticum vulgare_), does not grow as high as the rye, but has a thicker stalk and thicker ears, which are composed of several small ears. In each little ear there are generally four seeds. There are, as a rule, no beards; but, on the other hand, there is often a short spur at the top of the ears. It grows in temperate climates, the largest crops being raised in United States (especially in Minnesota, North Dakota, Ohio, South Dakota and Kansas); Central Europe (Russia, France, Austria-Hungary and Italy); India, Argentina, Canada and Australia. The area of wheat production is steadily increasing and wheat raising has become an important industry in newly developed countries, such as parts of British America, West Australia and Manchuria.
CULTIVATION.--The soil conditions in the Middle West are most favorable for giving quality. Its rich prairies contain large amounts of decaying vegetable matter, and because of the lime and alkaline substances in these soils, the elements of plant food are readily available, particularly the nitrogen in the soil, that contributes so largely to the glutinous character of the wheat.
Wheat is more than ordinarily adapted to machine farming and the invention of the successful reaper was largely responsible for the rapid increase of wheat acreage in America. In many parts of the wheat region immense plows drawn by traction engines and turning six to twelve and more furrows are employed. In other portions where operations are large many fields are plowed only once in two or three years. For various reasons, among which may be mentioned the control of weeds and the conserving of moisture in the soil, early plowing for winter wheat is preferable, and where the rainfall is scant very satisfactory conditions are obtained by stirring the surface soil with disc harrows only.
