In 1914 the spring wheat was again grown in replicated fiftieth-acre 
plats. The seeding was done on April 20. The precipitation in May 
and June was above normal. Hot, dry weather hi July and August 
caused the wheat to ripen early and reduced the yields. 
The year 1915 was marked by abnormally high rainfall and low 
temperatures during most of the growing season. The spring wheat 
was sown in replicated plats on April 9. The yields were the highest 
recorded at the substation. 
SUMMARY OF SPRING-WHEAT YIELDS. 
Table XV gives the annual and average yields of 25 varieties of 
spring wheat grown in plat tests at the Judith Basin substation dur- 
ing periods of varying length from 1908 to 1915, inclusive. 
This table shows that the Galgalos (C. I. Xo. 2398) has produced 
the highest average yield both for the 4-year period (1908-1911) 
and the 7-year period (1908-1911 and 1913-1915). This wheat is a 
soft variety and is of less value for milhng purposes than the hard 
wheats. The next highest yielding variety is a durum wheat, the 
Pelissier (C. I. Xo. 1584). This variety has a 7-year average yield 
of 27.2 bushels per acre, which is only 0.4 of a bushel less than the 
yield of the Galgalos. The durum group, as a whole, has yielded 
higher, on the average, than any other group.
