Hard red spring wheat is grown principally in the north-central part of the United States, where the winters are too severe for the production of winter wheat. The States of North Dakota, Minnesota, and South Dakota lead in its production. About 14 million acres of this class of wheat are grown annually in the United States, comprising about one-fourth of the total wheat acreage in the last 10 years.
Wheat is a plant of vast economic importance, widely distributed over the civilized world and having a history coincident with that of the human race. The grain is used largely for human food, chiefly as food-stuffs made from its flour, and in the form of breakfast food. The by-products of its manufacture are used as stock-food. The grain, whole or ground, is also valuable for stock feeding.
