AGRICULTURAL EDUCATION
BY DR.. ANDREW M. SOULE @@~

SOO1 cs.t>.5a',
has not been very satisfactory. Most
of the cCWpea silage we have seen
has been black and dark in color
and was unpalatable at least in ap-
pearance. We believe cowpeas can
be used in some of the ways indicat-
ed in this article to better advantage
than in the form of silage. We
think that other crops can be used
for the purpose of filling the silo at
a lower cost, and that cheaper
roughage can thus be provided for
the live stock of the farm than will
be afforded through ansiloing cow
peas.
1t seems unnecessary to further
emphasize the coWpea as a soil
builder or for general soil improve
ment purposes. 1t is too bad that
it is not mere extensively utilized
in the manner indicated. We can
make this crop yield profitable re-
turn by grazing it down and then
turning it under. Our southern
soils need nitrogen. All our crops
are benefited by heavy applications
Of this element. It is very costly
and apparently we cannot afford to
purchase and utilize it in CONNER
cial forms to the extent desirable.
We can, however, enrich and build
UP our lands materially by utilizing
the coWpea more extensively as q
green manure crop.
Will Varieties of Beans Mix?
E. v. L., Culberson, N. c.,
writes: Will soy, velvet or
mung beans mix if planted near
each other? I desire to plant
some chufas for seed this year.
I also wish to plant Mammoth
Russian sunflower seed. When
should both of these crops be
planted and how cultivated?
/ have never heard of the, velvet
bean and. the mung bean crossing,
and I do not think this would be
likely to occur. 1 think, in other
words, you could plant the velvet
bean and the mung bean relatively
close together without any danger of
their hybridizing.
Chufas or earth almonds are re-
garded by many as crop of value
for fattening hogs. This ground
nut is easily grown and ought to
be cultivated more extensively for
the purpose of fattening hogs. 1t
can be planted any time from April
to June. The cultivation is identi-
cal with that practiced in the case
of peanuts. The crop as q rule ma.
lures about September Is. 1t may
be left in the ground for a long
period of time. The yield of chufas
varies anywhere from 100 to 200
bushels per acre. There are records
of much higher yields, but prob
ably the figures presented Indicate
a fair average. Plant the crop in
2.5 to 3-foot rows, dropping the
seeds about one foot apart, and COW
quires one to one and a half pecks
of chufas to seed an acre.
The Mammoth Russian sunflower
is probably the best to grow for
grain production. Yields Of so BUSH
els and upward per acre are often
obtained. This crop may be plant
ed any time after the soil warns
up sufficiently to induce the rapid
termination Of the seed. Prepare
the land and plant the sunfiowers in
much the same manner you would
handle a corn crop. When the seeds
are mature they are as a rule har-
vested and dried out and threshed,
and then used as poultry feed.
Controlling Irish Potato Bugs
T. r. H, Tallulah Lodge, Ga,
- writes: wish to know how to
keep Irish potato bugs in check
so they will not do any damage
to the crop. have Paris green
on hand, and wish to know with
what to mix it and in what pro-
portion.
Irish potato bugs can be effective
ly controlled by proceeding as fol-
lows: Apply Paris green or arse
nate Of lead as soon as the plants
get started out of the ground. 1t
is important to destroy the seed crop
of bugs, as it were, to prevent their
laying large number Of eggs. This
material should be applied once ev-
cry three weeks. It may be neces-
sary to put it on oftener, as it should
certainly be re-applied after every
rain. The spray should be made
up in the proportion Of one pound
of arsenate of lead to 25 gallons Of
water. This mixture will be found
specially effective to use against the
young larvae. AS the season adj
vances and the insects become older
they are more, difficult to kill, there
fore it is generally advised in the
later stages Of growth and devel-
opment of the crop to use one pound
Of Paris green, 2 pounds Of arsenate
of lead, and so gallons of water.
Arsenate of lead is preferable to use
as compared with Paris green alone,
because it does not injure the pota-
the tops to some considerable extent
if used in too large a proportion.
Another method of applying the
Paris green is to use it in the dry
or powdered form. In that event
it should be mixed with about 16
pounds Of well dried road dust or
low grade flour. Slaked lime may
also be used for a small patch of
potatoes. This method of applica.
ton is very effective, as any Of the
combinations suggested my be dust
ed on the plants while the dew is still
on them.
The Weight of Bushel of Peanuts
S, E. D., Warrenton, Ga,
writes: How many pounds Of
peanuts in the shell in bushe1?
What is the standard for Geor-
gia?. ...... 49, ..
