SCOPE OF THE INVESTIGATIONS. 
Extensive varietal experiments with Kherson and Sixty-Day oats 
have been conducted in the United States during the past 15 
years. Prior to 1900 these varieties were practically unknown in 
this country, but to-day they are probably more generally grown than 
any of the older varieties. In this comparatively short time they have 
become widely distributed and are now of great commercial im- 
portance. 
The general popularity of these oats must be attributed largely to 
their early maturity and their ability to produce high yields. In 
sections where oats are grown primarily for market they have not 
met with favor because of their yellow color, but the small thin-hulled 
grains are highly regarded by farmers for feeding. 
Varietal experiments including the Kherson and the Sixty-Day oats 
have been conducted by the State agricultural experimental stations 
and the United States Department of Agriculture for periods varying
