CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION. TAT 
MIDSEASON VARIETIES. 
Seven of the eleven varieties under discussion may be classed as 
medium in maturity. The average date of ripening of these varieties 
for the seven years ranges from August 2 to 5, 101 to 103 days being 
required from seeding to maturity. Six of these varieties have 
yielded more than any of the early or late oats, while the seventh, 
Swedish Select, has yielded less than the two stocks of White Russian. 
All are open-panicled varieties and all have white hulls except Prob- 
steler, which 1s yellowish white. 
The farmer in the locality of Williston who grows any of these 
varieties, with the possible exception of Swedish Select, will make no 
mistake. The average yields here reported show that there is little 
choice between them, though Abundance, Lincoln, Siberian, and 
Silvermine have slightly exceeded the others in average yield, due in 
part to their extremely high yields in 1914. The weight per bushel 
of the Silvermine is higher than that of any of the other varieties in 
the test. : 
LATE VARIETIES. 
The White Russian and Tartarian are very similar, if not identical, 
varieties of late oats. They mature about August 6 to 9 at Williston, 
requiring from four to six days more from seeding to maturity than 
the midseason varieties just discussed. The heads are long, com- 
pact, and turned to one side (side, or horse-mane, oats). The kernels 
are white, long, and slender. In favorable seasons they usually 
yield well, but in ordinary or particularly unfavorable years they 
usually fall far below the earlier varieties. 
The 7-year average yield of the best White Russian (C. I. No. 732) 
is 74 bushels lower than that of Abundance, the best open-panicled 
variety. Both stocks of White Russian have yielded more than the 
Tartarian, though the difference is largely due to the low yield of the 
latter in 1914. The yield of the Tartarian was low in 1914 because of 
poor germination and the poor stand which resulted. 
Except where large acreages of oats are grown, so that it is doce nle 
to have the maturity of the crop extend over a considerable period 
to prevent losses in harvesting, the growing of side oats in this dis- 
trict is not recommended. 
RATE-OF-SEEDING TEST -WITH OATS. 
A rate-of-seeding test with oats has been conducted for four years 
(1911 to 1914) at Williston. The Swedish Select variety has been 
used in this test, in which the rates of seeding were 2, 4, 6, 8, and 10 
pecks. The 10-peck rate of seeding was discontinued in 1914. The 
results of this experiment are shown in Table XIV.
