Milo is one of the non-saccharine sorghums especially adapted to dry regions, and the most successful summer grain crop for the southern half of the plains country. It does not rank with the sweet sorghums and Kaffir corn as forage, being principally valued for its seed, which makes a satisfactory substitute for Indian corn.
Jerusalem Corn is also a non-saccharine sorghum. It is cultivated mostly in the cooler climates of the dry regions. It will mature in a short season, and is quite productive of seed, but its fodder yield is light.
Broom-Corn, a non-saccharine sorghum, is grown only for its brush for making brooms. It is a hardy plant, withstanding dry weather well, and is grown chiefly in Oklahoma, Illinois and Kansas. There are two varieties—the Standard and Dwarf, the former growing taller and producing the longer brush.
In adaptability sorghums cover about as wide a range of soils and climate as corn, and are noted for their drought-resisting powers. Kaffir corn is especially adapted to hot, dry and semi-arid portions of the West, where corn is uncertain, and there it is regarded with increasing appreciation.
In some places the juice of sorghum is boiled down to make sirup or sugar. Common brooms are made of the tops of the Broom-corn.
Spelt (Triticum Spelta) is chiefly cultivated in south Germany, but is also grown in a small way in some of our northwestern states. It is sown in both fall and spring, dealt with the same as other wheats, and some authorities recommend it as a very hardy drought-resistant grain for semi-arid regions. About seven pecks of seed are sown to the acre, and the yield is from twenty-five to sixty bushels per acre. The small ears are arranged on a brittle stalk, and consist of three or four blooms, of which, as a rule, only two are fruitful. Spelt is, generally, not bearded. The corn furnishes a white bread. When unripe, it is manufactured into a soup, which is highly esteemed.
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 [128] 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.
