tie oat smut appeared during the variety test, and the smut resistance 

 of Markton was not a factor in influencing yield. 



Midseason varieties were uniformly unproductive. Swedish Select, 

 the only midseason variety grown continuously, produced 17.6 bushels 

 per acre during the 10-year period as compared with 28.1 bushels for 

 Sixty-Day over the same period. 



Brunker appears to be the variety best suited to this section, and 

 its increase is recommended.

White Smyrna (C. I. 658) was outstandingly more productive than 

 other varieties. During the period 1926-32, its average yield was 4.2 

 bushels per acre higher than that of any other variety. Ace, a variety 

 grown from 1928 to 1932, equalled White Smyrna in yield. This 

 variety is a selection of White Smyrna and was grown under the 

 impression that it was taller, but it proved to be shorter than White 

 Smyrna. As one of the principal objections to White Smyrna is its 

 short straw, Ace appears to be no improvement. 



Vaughn barley, a short, stiff -str awed, six-rowed variety, produced 

 yields approaching those of White Smyrna during the 4 years it was 

 grown. It may be valuable for replacing White Smyrna on soils 

 where that variety lodges. Without production data during good 

 years, it is impossible to tell to what extent Vaughn will respond to 

 more favorable conditions. 



In nearly all years a good quality of grain was obtained from 

 White Smyrna, even in years when many other varieties produced 

 shriveled grain. The dependable production and good quality of
