h a view of aiding in the
better preservation of the ensilage and of making a better balanced
ration. Good alfalfa silage is more easily made when the alfalfa has
been run through a cutting-box than when in the uncut forms.
=Harvesting for Hay.=--The best time to harvest alfalfa for hay is just
after the blossoms begin to appear. Ordinarily, not more than one-third
of the blossoms are out when the harvesting should begin, but when the
hay is to be fed to horses the cutting may be deferred until more than
half the blooms are out. If cut earlier, the loss of weight in the crop
will be considerable, as much as 30 to 45 per cent., as compared with
cutting when in full bloom. If cut later, the stems become over-woody,
and the loss of leaves in curing will be much greater. When the cutting
is delayed beyond the period of early bloom, the growth of the next
cutting is retarded, and when it is deferred until some of the leaves
turn yellow or until some seed is formed, in many situations the
influence on the succeeding crop is seriously adverse, and in some
instances this influence would seem to react against the vigorous growth
of the plant during the remainder of the season. In other instances, as
where the conditions are quite favorable to the growth of the plant,
these results are not present in so marked a degree. When large areas of
alfalfa are to be harvested, the importance of beginning early cannot
easily be overestimated. It would be much better to sacrifice something
in loss of weight in the hay, through cutting too early, than to meet
with greater loss in weight in the next crop or crops by cutting too
long deferred.
Much that has been said about the harvesting of medium, red clover
will apply equally to alfalfa. (See page 95.) The mowing should begin as
soon as the dew has lifted in the morning. The tedder should follow
after the hay has wilted somewhat, and later, the horse rake, the aim
being to get the crop made into winrows, preferably small, before
nightfall, and when the weather is uncertain, the aim should be also to
put the hay up into small cocks the same evening. This may not always be
practicable. If the loss of leaves is likely to be considerable when
raking the hay, raking should be deferred until the influence of evening
dews begins to be felt. After the hay has become wilted it should not be
stirred or handled any more than is really necessary, that loss of
leaves and of the tips of the stems and b
