US Pacific Northwest bread wheat variety acreages 1919 to 2011

This dataset has common wheat variety acreage data for the three U.S.
Pacific Northwest states of Idaho, Oregon, and Washington from 1919 to
2011. The variety acreage data were compiled from the five-yearly
Distribution of the Varieties and Classes of Wehat in the United States
reports and the data provided by the USDA National Agricultural Statistics
Services. Acreages of only named varieties have been included, i.e.,
acreage reported under undefined names such as "others" have
been excluded. Acreages of variety mixtures, when reported in the orignal
sources, were evenly split to the component varieties.
