In 1914, three varieties, differing distinctly in size and 
length of growing season, were planted at five different rates. 
Pride of the North produced its maximum yield at the rate 
of five plants per hill. University No. 3 produced identical 
and maximum yields at both the two and the three-rate and 
then fell off sharply. Hogue's Yellow Dent produced its max- 
imum yield at the two-rate and then fell off sharply. 
The data in both Tables 23 and Table 24 indicate that 
the relative yielding power of varieties differing in growth 
habit can only be determined by planting at several rates. 
Different varieties have a different optimum rate of planting.
