The crop yield data used in this study were secured from the soil experiment fields operated by the Illinois Agricultural Experiment Station. Most of these fields were established during the years 191o to 1915. The crops considered in the discussion are those of the 15-year period ending in 1935 ;4 hence, the plats were well established by several years of preliminary cropping prior to 192o, the first season from which data for this particular study were used. Substitute crops or other irregularities occurred once during the period on five of the .fields and an earlier year’s yields were used to complete the i5-year sample. This shift seemed justified because it was possible to secure an income by growing a crop other than corn. The fields were laid out so that each crop of the rotation used was represented each year. Most of the plats were one-tenth acre in size. A few fifth-acre and a few twentieth-acre plats were used.
