During the 8-year period, 1912 to 1919, inclusive, the White 

 Eussian variety averaged 51.7 bushels per acre. This was higher 

 than anj^ of the other varieties grown during the period. The aver- 

 age yield of White Eussian during the 5-year period, 1915 to 1919, in- 

 clusive, was 57.9 bushels per acre. A panicle and spikelets of the 

 White Russian oat 

 are shown in figure

 same period the Sil- 

 vermine variety av- 

 eraged 58.2 bushels 

 per acre. Panicles 

 and spikelets of the 

 Silvermine and 

 Swedish Select vari- 

 eties are shown in 

 figure 17. The 

 Sixty - Day variety 

 averaged only 47.3 

 bushels. These 

 yields are shown 

 graphically in fig- 

 ure 18.

land. Because of its slow maturity the White Russian, a late side 

 or horse-mane oat, is able to utilize the soil moisture and to occupy 

 more of the growing season. Of the midseason varieties, Silvermine 

 has given the highest yields and is perhaps the best variety for the 

 irrigated lands. Several other midseason varieties, such as Cana- 

 dian and Swedish Select, produce large, plump grains, but the 

 average yields have been less than "VATiite Russian and Silvermine.
