Growing rye in the western half of the United States

"The production of rye in the United States has increased rapidly within the past few years. This increase is illustrated by the maps (Figs. 1 and 2) showing the distribution of rye in this country in 1909 and 1919. the increase in production is due chiefly to a heavy foreign demand, high-priced labor, low yields of wheat, and the development of improved varieties of rye, including Rosen, Dakold, and several others. The hardiness, vigor, earliness and low production costs of winter rye have permitted it to compete successfully with spring wheat. Recent low prices for rye, however have made the crop less profitable than formerly. If rye is to maintain its importance in the future it must be fitted into its proper place in the farming system. suitable cultural methods and good varieties are equally essential. A continued foreign market for our surplus also is necessary. These problems are discussed in this bulletin."--Introduction.
