The annual and average yields of the two early yellow varieties, 

 Sixty-Day and Seventy-five Day, and of eight other varieties of oats 

 grown at the North Dakota Agricultural Experiment Station at 

 Fargo during six or more years of the 8-year period from 1901 to 1908, 

 inclusive, are shown in Table XV. These results were obtained in 

 cooperation with the Office of Cereal Investigations.

1 S. P. I. No. 5168, similar to Sixty-Day. 



2 Probably the same as White Russian. 



The data in Table XV show that the early yellow varieties of the 

 Sixty-Day group considerably outyielded all others at Fargo in the 

 seven years for which data are available, the Sixty-Day exceeding 

 the Big Four, the best of the midseason varieties, by 3.7 bushels, and 

 the Tartarian, a late side oat, by 2.7 bushels. While these differ- 

 ences are not large enough to be regarded as significant, the yields 

 indicate that in this section of the Red River Valley the early oats 

 are at least as good as the midseason and late varieties. The so- 

 called ''Seventy-five Day" oat, an earlier importation from Russia, 

 probably identical with the Sixty-Day, has outyielded the latter 

 at Fargo by 8.5 bushels in a 6-year period. 



Under date of December 7, 1917, Prof. R. C. Doneghue, agronomist 

 of the North Dakota station, writes : 



It is my opinion, based on the trials here at Fargo, that the Sixty-Day oats are very 

 well suited to the Red River Valley. They stand up very well, yield well and will
