Abstract: Excerpts from the Preface: Rainfall and crop yields fluctuate widely in the Great Plains, making predictions of production difficult. In 1951, E. Lloyd Barber of the U. S. Department of Agriculture wrote a report entitled, "Variability of Wheat Yields by Counties in the United States." It contained average wheat yields and coefficients of yield variability by counties in the United States for 1926-48. The period covered years of extreme drought as well as years of bountiful rainfall. Favorable weather in the Southern Plains since 1948, except during 1952-56, and great strides in technology have tended to improve and stabilize yields in the Great Plains. The study reported here extends Barber's study through 1962 and shows average wheat yields and yield variability for 1926-48 and 1940-62 in 9 Great Plains States. It also includes coefficients of yield trend and yield variability for the entire 1926-62 period.
