The Kubanka produced relatively low yields at all stations. This 
was caused by the sterility of the florets, probably induced by a 
combination of drought factors. 1 The Ghirka ranked first in yield 
at Moccasin, Williston, Dickinson, and Newell; second at Edgeley 
and Brookings; and fourth at Highmore. The results of this year 
showed that the Ghirka variety possessed real value as a drought- 
resistant wheat. For all stations the Ghirka ranked first, Kysting- 
Glyndon second, Haynes third, and Kubanka fourth.
