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 feedmg. 



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
