Irrigation and Drainage 141 
with a single irrigation was in the beets irrigated when 
about two inches in diameter. 
The average weight of beets under the different treat- 
ments is given in Figs. 18 and 19, which show that the 
size of beets follows closely the relationships that have 
already been pointed out for yield. This was to be ex- 
pected, since the stand on all plats was practically the 
same in the spring and yield was largely, but not entirely, 
an expression of size. The size of beets irrigated only at 
the fourth state was proportionately smaller than the 
yield would indicate. 
The length of beets is also given in Figs. 18 and 19. 
Figure 18 illustrates that when seven and one-half inches 
of water were given each week, the length of beets averaged 
slightly less than those receiving no water. The longest
