CORN IMPROVEMENT 
Corn-improvement studies have been in progress for five years. 
The writer conducted the experiments independently in 1918 and 
1919. In 1920, 1921, and 1922 corn-improvement work was con- 
ducted as a cooperative project between the Offices of Cereal In- 
vestigations and Dry-Land Agriculture Investigations. Starting in 
1922 a definite project was formulated by the Office of Cereal In- 
vestigations for the improvement of corn at Akron, which will be 
continued in the future. Several promising selections of Swadley 
were made by the ear-row method in 1918, 1919, and 1920. The 
most promising of these strains is Akron White, selected in 1917, 
which has outyielded the parent variety by an average of over 10 
bushels per acre during the past five years. Two or three promising 
selections were made in 1919 and several more in 1920 and 1921.
