Fertilizing Value.--A heavy growth of the cowpea is worth as much to
the soil as a good crop of red clover. When the equivalent of two tons
of hay is produced, the roots and vines contain nearly as much
plant-food as the roots and first crop of medium red clover that makes
two tons of hay. Some analyses show a higher percentage of protein in
cowpea hay than in clover hay, and the experience of many stockmen
indicates that such is the case. The roots and stubble have somewhat
less fertilizing power than in the case of the clover, and all thin
soils should have the entire plant, or the manure from the hay, saved
without loss.
Comparison is made on the basis of equal adaptability of soil and
climate to clover and the cowpea. Going southward, the cowpea has the
advantage, and northward the clover gains. It is in the overlapping
belt that both should be freely used. The cowpea has distinct advantage
over the clover in its ability to supply nitrogen and organic matter
within a few months, and in its adaptation to very poor soils where
clover would not make much growth. As a catch crop it has great value.
Affecting Physical Condition.--The cowpea has marked influence upon the
physical condition of heavy soils, even when the vines are not plowed
down. This is due in some degree to the roots, and probably more to the
mulching effect of the vines during their growth. Heavy soils are made
much more mellow by the cowpea, and when the crop is removed for hay,
the stubble-land is easily prepared for a seeding to grass or small
grain. When the growth is plowed down, the soil may be made too loose
for seeding to small grain, but is put into prime condition for a
tilled crop.
Planting.--The land should be fitted as it is for corn. Light, sandy
soils require little preparation, and too often the seeding is made in
a woefully careless manner, the chief dependence being placed upon
sufficiently deep covering to insure germination. The ground should be
fitted as well as it is for a cash crop, being made fine and smooth. A
grain drill makes the seeding in a satisfactory manner, and the seed
may be drilled solid or in rows for cultivation. When the crop is grown
as a fertilizer or for hay, solid drilling is good, and about five
pecks of seed gives a good stand of plants if peas are sound. Much
cowpea seed is low in germination power, and the buyer should exercise
caution. When a seed crop is wanted, two to three pecks of seed per
acre, placed in drills 28 to 32 inches apart, make an excellent
seeding, as cultivation can be given. The amount of seed varies with
the variety. In northern latitudes a warm soil is to be desired, and
cultivation gives better results when a seeding to wheat will be made
on the pea-stubble.
