On the whole, only small differences are exhibited in the yields 
from different methods of preparation for the corn crop. There is a 
slight advantage in favor of spring plowing over fall plowing on both 
corn ground and small-grain stubble. The yields of both grain and 
stover were somewhat better when the corn followed small grain 
than when it followed corn. The relative response to these sequences 
was the same on both fall and spring plowing. 
The four preparations for corn — fall and spring plowing following 
corn and fall and spring plowing following small grain — rank in order 
of yield obtained as follows: (1) Spring plowing on small-grain 
stubble, (2) fall plowing on small-grain stubble, (3) spring plowing on 
corn ground, and (4) fall plowing on corn ground. Average profits 
ranging from $1.38 to $2.74 per acre have been realized by these 
methods. The difference exhibited in the results attending the use 
of these methods is not great enough to be in itself a determining 
factor in the choice of rotations or in the management of the farm and 
its work. Summer tillage as a preparation for corn has given poorer 
results than any other method. In only one year has it been pro- 
ductive of the largest crop. The average yield of both grain and 
stover by this method is less than by any other method under study. 
The value of the average corn crop on summer-tilled land has been 
$3.79 per acre less than the cost of its production as crop values and 
comparative costs are here computed.
