144 FORAGE CROPS 
at the proper time, it is a very useful crop, al- 
though the experience of careful experimenters 
shows that, on the whole, the yield of feed is 
relatively very much less than from the regular 
field varieties, the range being from four to ten 
tons per acre, with an average of about six tons. 
A variety of sweet corn that gives a satisfactory 
yield is rather slower in development than other 
corn, owing largely to the fact that the seed does 
not germinate quickly nor the young plants grow 
vigorously until the season is well advanced. Of 
the suitable varieties, Stowell Evergreen is one 
of the most generally satisfactory, since it is a 
large, rank grower, with abundant foliage. It 
should not be planted until the season is well 
advanced, say the latter part of May, for the Cen- 
tral States, and the land should be thoroughly well 
prepared, as pointed out for other kinds of maize. 
When used primarily for forage, sweet corn may 
be fertilized or manured, as indicated for the 
Thoroughbred White Flint, and cultivation should 
be practically.the same. 
A great advantage that many dairymen find in 
the growing of sweet corn is that they may sell 
a large proportion of the ears, when the prices 
are satisfactory, and still have a very good for- 
age left, as the stalk remains palatable for a con- 
siderable time after the ears have been removed. 
There is no question as to the superjority of the
