SILAGE AND SILAGE CROPS
By J. B. THOMPSON
In some respects silage is especially suited to Florida con-
ditions. The proper curing of hay is more or less dependent upon
dry weather at harvest time, which condition is not essential for
the preparation of good silage. As a supplement to the grain
ration, silage is highly valuable as a feed for livestock, especially
The crops that have proved most satisfactory for silage in
this State are corn, the saccharine sorghums, and Japanese cane.
From the standpoint of quality, corn is unquestionably superior
to all other crops for silage. Because it contains less sugar it
undergoes less fermentation than do either the sorghums or Jap-
anese cane, and consequently is less acid and more palatable than
is the silage from either of these crops.
It has been shown that of the total digestible food constitu-
ents in a crop of corn, 63% is stored in the grain and 37% in
the fodder. This plainly indicates the high value of corn fodder
when converted into a good grade of silage. Usually the varieties
that are found to produce the best yields of corn will also be
found most desirable for silage purposes. Planting and culti-
vation differs little from that where the usual grain crop is the
prime object, tho for silage a little closer planting should be
practiced. The crop is ready to harvest as soon as the grain
has reached the glazed condition, and in order to obtain best
results it is important that the work of filling the silo be done
promptly at this time.
Sorghum produces a feed only a little inferior to that of
corn silage. Its greater drought resistant qualities and ability to
succeed on relatively poor land often insures better yields on
light dry soils than could be had from corn. As in the case of
corn, the proportion of grain directly influences the quality of

the feed. There are a number of varieties that are satisfactory
for silage purposes, but those that return the heaviest yields
of green feed are usually preferable. Early Amber and Orange
are quick maturing sorts, but for general planting in Florida
this is no particular advantage, and the yields are considerably
less than are those from some kinds that require a little longer
season. Red Top or Sumac is a well known variety that is one
of the best for planting in Florida. During the past year this
variety yielded in a plot test at the Florida Experiment Station,
a little more than 14 tons of green feed against less than 91/2
tons from the Early Amber variety. These figures are intended
to indicate the relative yields of these varieties and are con-
siderably more than average yields. Sorghum may be planted
from March until June. Sumac sorghum requires from 100 to
120 days to make the first crop, and two crops may be secured
from early plantings.
Japanese cane will yield much heavier crops than either
corn or sorghum; and where it is allowed to mature well and is
carefully packed in the silo, the results will usually be found
satisfactory. Japanese cane produces no grain and will not,
therefore, be equal in feeding value to either corn or sorghum.
In feeding it an allowance of grain should be given to counter-
balance this deficiency. The feeding value of Japanese cane
lies largely in its high content of sugar, much of which develops
late in the season as the crop approaches maturity. For this
reason it should not be cut until well mature. Furthermore
there is a tendency for the immature growth to undergo ex-
cessive fermentation which may result in sour, highly acid silage
of poor quality.
Thoro packing in the silo is a precaution that should be
observed in the preparation of all silage, regardless of its source.
In the case of Japanese cane this is especially important, for
owing to its more leafy nature it is less easily packed than either
corn or sorghum.
