CEREAL EXPERIMENTS AT DICKINSON, N. DAK. 31 
Table XIV shows that the early varieties, the Kherson and Sixty- 
Day, matured in about 103 days after planting. The medium-early 
varieties, such as the Early Mountain and Victory, mature in about 
117 days, the medium-late variety, Banner, in 123 days, and the late 
variety, White Russian, in 128 days. The average date of heading 
for the medium-early varieties is July 11 and the average date of 
ripening August 138. The early varieties mature about two weeks 
earlier and the medium-late and late varieties 6 and 11 days later, 
respectively. The time of maturing is an important feature to be 
considered with the oat crop. Early varieties often escape climatic 
conditions, such as hail and hot winds, that seriously injure later 
varieties. 
The average height of the early varieties is about 28 inches, which 
gives sufficient length of straw for binding. The average height of 
the other varieties is about 36 inches. Stand notes which have been 
taken for a number of years show no definite correlation with yield 
between the different varieties. The early varieties yield less straw 
than the later ones; hence, the latter are to be preferred when the 
straw is to be used for feed. The earlier varieties also usually weigh 
less to the measured bushel. The medium-early varieties, however, 
yield well in straw and the weight per bushel is high. 
BARLEY. 
The varietal trials of barley have been conducted in much the same 
manner as those of wheat and oats. In 1907 and 1908 the barley 
varieties were grown on new land which had been broken the previous 
year. In 1909 and in succeeding years they were grown on corn land 
disked just previous to seeding. The usual date of seeding has been 
about April 20, though in 1912 the seed was not sown till May 8. 
The rate of seeding has varied from 8 pecks to the acre in 1907 and 
1908 to 5 pecks in 1912 and 1913. In 1912 the second growth, which 
was produced after the hailstorm of July 11, matured seed, but only 
four varieties were thrashed because of lack of help. 
The actual acre yields obtained from 16 varieties grown at Dickin- 
son from 1907 to 1918 are presented in Table XV.

in bushels of 60 pounds, the standard weight, would be one-fifth less.
