VARIETAL EXPERIMENTS. 
During the 12-year period from 1908 to 1919, inclusive, 19 varie- 
ties and strains of spring oats have been grown in plats. It was 
soon found that only the early varieties were well adapted to the 
region, but a few midseason and late varieties were continued in the 
experiments for comparison. Only three varieties of oats were grown 
during all of the 12 years. Several early varieties and strains were 
added to the experiment in 1910. 1912. and 1916. The annual and 
average vields of the oat varieties are shown in Table XVIII.

Table XVIII shows that good yields of oats were obtained from 
all early varieties in 1908, 1915. 1916, 1917, and 1918. Fair yields 
were grown in 1909 and 1913, and poor yields or failures in the 
other years. In 1909, 1912, and 1918, the midseason and late varieties 
were somewhat favored by ample moisture late in the season. In 
years such as 1910, 1914, 1917, and 1919. when the season was very 
dry. the early varieties yielded better than the later ones. The 
Kherson variety, C. I. No. 459, gave the highest average yield. 29.7 
bushels per acre, during the 12-year period. A panicle and spikelets 
of Kherson oats are shown in figure 9. The Swedish Select and
