There is a lack of consistent differences in the production by differ- 
ent methods from year to year and of any wide variation in the aver- 
age results for the whole period of years. Marked responses to 
cultural conditions indicated in certain seasons are balanced by dif- 
ferent reactions in other seasons. If no marked benefit attends the 
use of any method, greater freedom is left in the choice of methods. 
With the values of grain and fodder and the comparative cost of 
production as here computed, the corn crop shows a profit by all 
methods under which it has been grown. The least profit, $6.53 per 
acre, has been from summer-tilled land. Greater profits have been 
realized from corn after small grain than from corn after corn. Only 
small differences are exhibited in the profits realized by fall plowing 
and spring plowing. 
A study of other crops at this station has shown them to be more 
responsive than corn to differences in cultural conditions. The place 
of corn in the rotation should therefore be subordinated to the in- 
terest of the other crops. 
The comparatively small-growing varieties of corn which are 
planted in this section produce a high percentage of leaves, which 
give a high value to the fodder. When grain is produced it makes 
the feed all the more valuable. The production of a large supply of 
good feed per acre, together with the fact shown in other studies that 
corn is one of the best crops to precede small grain, should give this 
crop an important place in the farm economy of this section.
