n sown to produce
hay, it is nearly always sown in mixtures, but to this there are some
exceptions; when sown to produce pasture, it is almost invariably sown
with something else; and when sown to enrich the land, it is, in all,
or nearly all, instances, sown without admixture.

When sown primarily to produce seed, there are no good reasons why
timothy and probably some other grasses may not be sown with medium red
and mammoth clover, when pasture is wanted from the land in the season
or seasons immediately following the production of seed.

The presence of these grasses may not seriously retard the growth of the
clover plants until after they have produced seed, and subsequently they
will grow more assertively and produce pasture as the clover fails.
Moreover, should they mature any seed at the same time that the clover
seeds mature, they may usually be separated in the winnowing process,
owing to a difference in the size of the seeds. But timothy should not
be sown with alsike clover that is being grown for seed, since the seeds
of these are so nearly alike in size that they cannot be separated.

When hay is wanted, the practice is very common of sowing timothy along
with the medium red, mammoth and alsike varieties of clover. Timothy
grows well with each of these; supports them to some extent when likely
to lodge; matures at the same time as the mammoth and alsike clovers;
comes on more assertively as the clovers begin to fail, thus prolonging
the period of cropping or pasturing; and feeds upon the roots of the
clovers in their decay.

Next to timothy, redtop is probably the most useful grass to sow with
these clovers, and may in some instances be added to timothy in the
mixtures. Some other grasses may also be added under certain conditions,
or substituted for timothy or redtop. In certain instances, it has also
been found profitable to mix certain of the clovers in addition to
adding grass seeds when hay is wanted. The more important of these
mixtures will be referred to when treating of growing the different
varieties in subsequent chapters. When growing them, the aim should be
to sow those varieties together which mature about the same time. The
advantages from growing them together for hay include larger yields, a
finer quality of hay, and a more palatable fodder.

In the past it has been the almost uniform practice to sow alfalfa
alone, but this practice is becoming modified to some extent, and is
likely t
