AGRICULTURAL EDUCATION
BY DR.. ANDREW M SOULE

| eight inches apart on poor soil tc
eighteen inches the richer soils
Thick spacing with chopping done
as early as all danger of dying i:
over usually gives the highest yields
On the college farm, land that pro
duced about two bales per acre, twt
plants per hill, eighteen inches apart
gave the highest yields in tests made
before hte advent of the weevil.
Cultivation Between Rows
| In cultivation cotton, the following
principles should be kept in mind:
1. Most Of the roots are found ir
that part of the soil broken in pre-
pairing the seed bed and the plant
food is taken from that part of tbs
soil.
2. Very little plant food is derived
from that part of the soil stirred by
the pillow during the cultivating pc
riod.
This leaves the space between the
bottom of that part cultivated and
the bottom Of the area broken, fol-
the plant to secure it's food form. II
will be seen at once that breaking
the land five inches deep and cult
waiting four inches deep leaves lit
tie room for root development and
very poor plant is to be expected
Cultivate Soon After Chopping-
Cultivation should follow chopping
as soon as possible as the plants are
left without support and can be very
easily damaged by heavy rains and
high winds. The first cultivation
may be fairly deep without damage,
but all later civilizations should
never be more than one and one
half inches deep. The scrape with
scooter going deep in the soil will
break many feeding roots, and is
the poorest type of implement that
can be used for cultivation.
A sweep that can be regulated to
run shallow is a better implement,
but is hard to use in rough land.
The single stock pillow is very slow
and inefficient, and adds greatly to
the cost of production.
Among the one-horse implements,
the Planet, Jr., type does excellent
work. It is a combination tool, and
can be used for bedding as well as
cultivating. With small sweeps at
tached, this implement covers a
larger area than single stock, and
runs shallow, being very easy to
handle with a little experience.
Two-Horse Cultivator Best Imple-
ment-A riding two.horse cultivator
Of the pivot axle type is the best
implement to use where the lay Of
the land will permit. 1t is COM
bination tool, and can be used for
laying off rows, bedding land, OPEN
ing up rows and cultivating. Disk,
spring tooth and gang attachments
for turner's and sweeps can be Sc
cured with most makes. These ma
chimes are light of draft, easy to
guide, and can be regulated to Gull
tivate as shallow as desired. The
rapidity with which fields can be
covered lowers the cost Of cultiva-
ton considerably since complete row
is worked at each passage and the
labor of one man is saved.
Cotton should be cultivated after
every rain, and no more land should
be planted in cotton than can be
gone over rapidly. Cultivation should
be very rapid in the spring to force
a rapid growth and conserve mois-
ture. When there are extremely
long, dry spells, cotton should be
cultivated before the next rain as
this aids in conserving the scanty
supply Of moisture.
In many sections there is a ten
dency to quit cultivation too early
in the summer, but cultivation
should extend late into the year and
be very shallow.
Using Calcium Arsenate Against
the Boil Weevil
Use only pure calcium arsenate in
the form of dry powder.
Apply. only in the dust form with
out mixing with anything.
Apply only with busting machine
made for busting cotton.
Dust only when the air Is still.
Best results come from night dust
ing.
Use five to seven pounds Of CAL
cium arsenate per acre for each APP
plication.
Start busting in any field as soon
as weevils are in all parts of that
field. Some fields need busting
earlier than others.
Keep cotton thoroughly covered
until weevils are under control.
This means dust every four days
after beginning until three or four
applications have been made.
Then stop poisoning until weevils
are bad again.
If you have heavy rain in few
hours after busting, dust the same
field again Immediately.
Do not expect to kill all the wee
wills, Calcium arsenate only keeps
them down enough to permit crop
to be set.
