The data in Table XXX show that both the midseason and late 

 white oats have decidedly outyielded the Sixty-Day at the Langdon 

 substation. 



The yields of the side-oat varieties, New Zealand, White Russian, 

 and Select Tartarian, have averaged several bushels more than those 



of the midseason open-pan- 

 icled varieties. This condi- 

 tion occurs so rarely that it 

 seems worthy of special men- 

 tion. Early oats are not rec- 

 ommended for this section of 

 North Dakota. A panicle and 

 spikelets of the White Russian 

 oat are shown in figure 10. 



RESULTS AT EDGELEY. 



The annual and average 

 yields of the Sixty-Day, the 

 Kherson, and seven other va- 

 rieties of oats grown at the 

 Edgeley, N. Dak., substation 

 (45, p. 28) during three or 

 more years in the 10-year 

 period from 1903 to 1912, in- 

 clusive, are presented in Table 

 XXXI. 



According to the data given 

 in Table XXXI there is little 

 choice between the early yel- 

 low and the midseason white 

 varieties for growing in the 

 vicinity of Edgeley. Only 

 the Siberian, Sixty-Day, and 

 Swedish Select have been 

 grown during the entire period. 

 They rank in average yield in 

 the order named. In the six 

 years from 1905 to 1910, inclusive, the Abundance, Big Four, Siberian, 

 and Sixty-Day produced almost identical average yields. The results 

 appear to be slightly in favor of the midseason varieties. It is 

 probable that the rather thin soil of this section accounts for the 

 better performance of early oats at Edgeley than elsewhere in North 

 Dakota.
