The three grains here treated, viz.: wheat, rye and corn, belong to the vast order of plants known as the grass family (Gramineæ). This large group of plants, the members of which are so closely related as to be quickly recognized as such, contains many of the most valuable of all cultivated plants. It not only furnishes the cereals, namely: wheat, rye, corn, oats, barley and rice, which supply the world with the larger part of its starchy food, but clothes the pasture and meadow of the farmer with the herbage so essential to the sustenance of his live stock. There is a deep and weighty truth in the familiar expression: “All flesh is grass.” Blot out the grass family from existence and nearly all forms of life would suffer, and many kinds would soon perish from the earth.
The grasses are usually low and comparatively small plants—though the bamboos of the tropics are almost treelike, with jointed stems and alternate, slender leaves. The flowers are inconspicuous, usually in spikes or spreading clusters, with three stamens, anthers versatile, styles two, stigma feathery, ovary one-celled, becoming a grain.
Wheat has probably more intrinsic value than any other plant grown. It is probably a native of southwestern Asia, but like most grains and fruits cultivated from remote antiquity, its early history is extremely uncertain. Many varieties have been produced from the original Triticum vulgare—the scientific name of wheat—but they can all be placed in the two following groups: Those that are tender called spring wheats, sown in spring, and the winter sorts that are sown in autumn, remain on the ground through the winter and are harvested the subsequent summer. The winter wheats are the more valuable and bring a higher price than the spring varieties. Some wheats have long awns to the flowers, and are termed bearded, while other sorts are nearly or entirely awnless, and are sometimes styled bald. There is a great variation in the size and color of the grain. In some varieties it is long, others short; some are white, others brown, red, and amber; some are hard, others are soft. New sorts are produced yearly, and the varieties have become practically innumerable.
The area devoted to the growth of wheat in the United States is between thirty-five and forty million acres, and the yield of the present season (1884) will not be far from 500,000,000 bushels. The average yield per acre, take the whole country through, is not far from thirteen bushels per acre. Nineteen states (and territories) cultivate over a million acres each; six over two millions, and three over three millions, namely: Illinois, 3,218,542; Iowa, 3,049,288; and Minnesota, 3,044,670 acres, as given in the last census. In the order of the number of bushels produced, the leading states stand thus: Illinois, Indiana, Ohio, Michigan, Minnesota, Iowa, California. New York stands thirteenth, and Rhode Island last, with seventeen acres and 240 bushels. It will be seen that the wheat region, strictly speaking, is in the Mississippi Valley, centering around Illinois, with a secondary area in middle California. According to the report on the cereal production of the United States by Professor Wm. H. Brewer, in the statistics of agriculture in the tenth census, the yield and quality of the wheat crops is stated to depend upon five conditions: climate, soil, variety cultivated, method of cultivation and the liability to destruction by insects. The quality of the grain depends more upon the climate than the soil. A hot, dry and sunny harvest produces a grain of the highest quality. The ideal climate for wheat growing is most nearly reached during the best years in California, and it is then and there that we have records of the greatest yields of the best of wheat.
A good rich soil is needed for successful wheat growing. This may be preserved on any farm by a well regulated system of crop rotation. It must be borne in mind that wheat has a short season for its growth and needs to have food prepared and close at hand. One of the best preparatory crops is clover. The clover sod, including the vast amount of roots, furnishes a most acceptable feeding ground for the wheat. The soil itself is not one of the items most frequently overlooked in wheat growing. The importance of good plump seed of the best varieties is rarely overestimated. There is a vast deal in the sort of wheat grown, and no one can afford to grow any but the best.
The most common diseases of wheat are rust and smut, both of vegetable origin. These troubles, which appear so suddenly and are often very destructive, are minute microscopic plants of the order of fungi, and therefore related to the moulds and mildews common on various articles of food, etc. The insect enemies are somewhat numerous, but the Hessian fly, wheat midge, joint worm, chinch bug, army worms, and Rocky Mountain locust are the most destructive. There are a few insects that prey upon the grain after it is in the granary, and these are on the increase. Among the enemies we should not forget to mention various weeds that spring up in the fields and endeavor to choke out the legitimate occupants of the soil.
The nutritive value and chemical composition of wheat grain are important points worthy of consideration here, because this general article is to be followed by one upon the culinary aspects of the grain treated. The market value of a flour largely rests upon its appearance, while the nutritive value depends upon the results determined by the analytical chemist. The average of fifty-seven analyses of winter wheat in the kernel gave:
| WATER. | ASH. | ALBUMINOIDS. | FIBER. | STARCH, GUM, &C. | FAT. | |
|---|---|---|---|---|---|---|
| Winter Wheat | 11.18 | 1.70 | 11.70 | 1.66 | 71.81 | 1.95 |
| Spring Wheat | 10.50 | 1.84 | 11.97 | 1.86 | 70.64 | 2.19 |
| Wheat Flour | 11.56 | 0.59 | 11.09 | 0.17 | 75.43 | 1.14 |
It will be seen that there is very little chemical difference between winter and spring wheats. The composition of the flour shows a removal of nearly all the woody fiber, two thirds of the ash, nearly half the fat and a small reduction of the albuminoids, while the water is somewhat and the carb-hydrates (starch, gum, etc.) considerably increased. It will be interesting to here give an analysis of wheat bran and shorts:
