rm of
years than any of the clovers, it is relatively more important that the
seed shall be sown with a view to seek a uniform and sufficient stand of
the plants.
Whether the seed is sown by hand, or by any of the hand machines in use,
the results will usually prove satisfactory, but in climates where
moisture is deficient, decidedly better results are obtained from sowing
the seed with some form of seed drill. A press drill is preferred in
soils so light and open as to dry out easily or to lift easily with the
wind. Under conditions of ample moisture, a light covering with a harrow
will suffice, but under conditions the opposite, more covering is
necessary. In areas where spring and early autumn showers are frequent,
the roller will provide a sufficient covering, especially where the
soils are well charged with a clay content. On other soils, as those
which cover much of the prairie, the seed should be buried from 1 to 2
inches deep.
Where alfalfa is much sown on soils well supplied with humus, and on the
soils which prevail in the Rocky Mountain region, many growers sow the
seed with the grain drill, and before sowing they first mix the seed
with some material, as earth, some kind of coarse meal, bran or other
substance to make it feed out more regularly. In some instances one-half
of the seed is sown the first time the drill is driven over the land,
and the balance is sown by driving again over the same at right angles
to the drill marks previously made. When thus sown, the plants are more
evenly distributed over the soil, and produce, it is thought, a more
uniform quality of stalk. This method meets, in part, at least, the
objection sometimes made to drill sowing, that it does not distribute
the plants sufficiently in the soil.
In the Northern and Atlantic States, also west of the Cascade Mountains,
and in some parts of the South, alfalfa is frequently sown with a nurse
crop, and under favorable conditions the results are usually
satisfactory, if the nurse crop is not sown too thickly. The best nurse
crops in the areas named are barley and winter rye, but oats will answer
also, if sown thinly and cut for hay. It has also been sown quite
successfully along with winter wheat in the spring and also with spring
wheat. When sown with winter wheat or winter rye, it is usually
advantageous to cover the seed well with the harrow. In many instances,
however, even in these areas, it is thought better to sow the seed
