BROOM-CORN EXPERIMENTS AT WOODWARD, OKLAHOMA. 37 
from sowings at different rates in the same year and from the same 
rates in different years are not alike, owing primarily to seasonal 
conditions. It is interesting to note, however, that the highest, yield 
was produced by seedings at the intermediate rates in three years 
of the 5-year period. The thickest rate outyielded all others in 1917, 
when there was 7 inches of rainfall in August, and the thinnest rate 
ranked first in 1918, when the rainfall in August amounted to 0.7 of 
an inch only. These are the extreme rates of seeding and they can 
give best results only under extreme seasonal conditions. 
The stand has an influence on the length of the brush. Thick 
stands tend to produce short brush, and thin stands long brush- The 
difference between the length of the brush produced by the thickest 
and the thinnest stands in the 5-year period ranges from 6 inches in 
1914 to 2 inches in each of the years 1915 and 1917. In 1916 it was 3 
inches, and in 1918 there was a difference of 5 inches.
