soils. If poor soils are Sc
lected, lower yields can be
expected. A well-prepared,
c6ep, but firm seeded is
important to corn production.
Try to flatbreak the soil at
least six inches deep and, if
possible, ten inches deep.
This will permit the roots
to go deeper and will i'm
prove the water holding ca
pacity of the soil.
Fertilization: The general
fertilizer recommendations for
corn are as follows:
Delta: Use 100 pounds of
available nitrogen per acre.
You may apply all the nitro
gen at planting or half of it
may be used at planting time
and the other as a sidedress-
ing when the corn is knee
high.
Hill and Delta Foothill
Section: Apply at planting
time a complete fertilizer in
sufficient amounts to give 36
pounds of available nitrogen
48 pounds of available phos-
phate and 40 pounds of avail
able potash. Side dress with
60 to 90 pounds of available
nitrogen when corn is knee
high.
Placement: Place these
rates of fertilizer at least
three or four inches to the
side and three to four inches
below the seed to prevent
root damage.
Spacing: On good bottom
land space plants Il to 16
inches apart on 38 to AZ inch
rows. On hill land or poorer
bottom land, space plants 10
to Is inches apart on 38 to
AZ inch rows. This will re-
quire nine to IA pounds of
seed per acre which is APP
proximately one peck. You
should increase number of
plants by about 20 per cent
when planting for silage.
Chemical Weed Control: A
good stand of fast growing
corn is one of the best weed
controls you can have. Cul-
tivation of corn should be Of
ten enough to control grass
and weeds. The last cultiva-
ton should be shallow to a.
void cutting the corn feeder
roots. For early control of
weeds and grass in corn, you
can use a -pre-emergence
chemical. Pre-emergence
chemicals recommended in
Mississippi are: l. Simazine.
It has given excellent control
Of all weeds and grasses with
the exception of Johnson
grass. 2. Duiron Karmex
KL). Apply in the same man
ner as when using duiron on
cotton, Pre-emergence of dull
ron should be avoided when
corn is planted under con-
ditions unfavorable to rapid
termination and growth. This
would be more likely to oc-
cur in early season. 8. Atra-
zine is very similar material
to Simazine. 1t is more readi-
~ soluble, therefore, it does
not require as much rain
fall following application as
Sibazine to give good results.
1t will not last in the sci
quite as long as Simazine.
When using Simazine 3r1
Atrazine follow directions On
the container.
Where using Duiron or
Karmex use from one-half to
two-thirds the amount you
would use in pre-emerging
cotton.
Duiron is not recommended
for extremely sandy soils or
heavy clay soils.
Planting Instructions: When
duiron is to be used, plant
the corn one and one-half
inches deep. This gives add
ed protection to the corn
from duiron.
P~ost-Emergence Weed Con-
troll: If weeds become a prob
lem after corn is up and
cannot be controlled by Gull
tivation, spray corn with a
broadcast application of 2,4-D
using one-third pound in ten
to 20 gallons of water per
acre. If it is necessary to
spray after the corn in II
inches high, use drop nozzles
or floodinp nozzles adjusted
that you will get q broadcast
coverage of the weeds with
out getting spray on the corn
except at the base of the
plant. One-half pound of
PAD per acre should be used
in ten to 20 gallons of water
for late spravinG Do not
srrov corn with Dad during
siltiro and tassel1ing.
24-D will do an excellent
