146 FORAGE CROPS 
the great superiority of the former, an average 
yield per acre of field varieties furnishing: 
100 pounds of fat 
860 pounds of protein 
2,440 pounds of nitrogen-free extract 
as against: 
60 pounds of fat 
228 pounds protein 
1,536 pounds of nitrogen-free extract 
for the sweet varieties, or a gain of nearly 60 per 
cent in all the different nutrients. The cost of the 
sweet corn forage is greater, owing to the much 
higher price of seed. 
DRIED CORN FODDER 
An advantage that corn possesses, and which 
makes it superior to practically every other plant, 
is the fact that, if the crop is not required in its 
green stage, it may be dried and used for fodder. 
While it contains a high content of dry matter, it 
cures readily, and for certain classes of feeding 
furnishes roughage that is unexcelled. 
Seeding and harvesting 
The varieties used for fodder may be practically 
the same as those recommended for green forage, 
although the seeding may be slightly thicker, as
