Corn Planting
Considerations
Planting corn seed to a depth of 1 ½” – 2” is optimum.
Planting too shallow inhibits nodal root development and
can lead to lodging. It also risks greater exposure of the
emerging plant to herbicide residue. Planting too shallow
can effect both brace and crown root development, which
are responsible for stabilizing young plants and help with
Other considerations:
• Good seed to soil contact is essential, as the corn seeds
require 1/3 of their kernel weight of moisture to germinate.
• Slower planting speeds produce more uniform seed
placement.

emergence. Achieving the maximum potential number
of heat units is critical for the success of corn in Western
Canada. Planting into cold soil does not increase the
potential for more corn heat units, waiting as long as you
can until soils warm up will ensure more even and faster
germination & emergence.
The growing point of the corn plant remains below the
surface until the sixth leaf appears. A slight frost prior to the
Plant population
An initial target of 32,000 plants/acre is a good starting
point. However, this may need to be adjusted depending
on field conditions. For example, under dry conditions use
lower target seeding rates to allow plants more access to
available moisture.
Use the following table to check seeding rates:
emergence of the sixth leaf will lead to leaf loss but should
not kill the plant.
Timing of herbicide application is an important factor in the success of your corn crop.
Weed control
Corn is planted in wide rows and its growth is slower at the
early stages versus other crops. Thus, early weed control
is very important. Row spacing between 15-30 inches

Consult your local Crop Protection Guide for herbicide
choices and recommendations. Be aware, corn hybrids
have different levels of herbicide tolerance to different
broadleaf herbicides. Your local Pioneer Hi-Bred sales
representative can help you select the best herbicide
options for the corn hybrids you are growing.
“In order to maximize yield potential, it is extremely important to keep the early
stage of corn development free of weeds.”

The DuPont Pioneer
Goss’s wilt advantage
The DuPont Pioneer Goss’s wilt advantage
Pioneer Hi-Bred has been screening and breeding for Goss’s wilt resistance for decades in the western U.S. Once this
bacterial disease spread into the northern corn belt over the last few years, Canadian researchers were able to leverage
the vast experience and knowledge available within Pioneer Hi-Bred to diagnose, characterize, and select resistant early
maturity genetics. This work will lead to improved Goss’s wilt resistance in the corn hybrids sold in Western Canada.
DuPont Pioneer currently conducts an industry leading corn hybrid screening program to select hybrids that are resistant
to Goss’s wilt. This will help growers in Manitoba to best manage this devastating disease and to prevent the spread of
Goss’s wilt to other areas. Contact your local Pioneer Hi-Bred sales representative for more information on testing corn for
Goss’s wilt infections. DuPont Pioneer researchers select corn hybrids for resistance to Goss’s wilt. Corn hybrids are rated
against known susceptible and resistant hybrids using Pioneer Hi-Bred’s rating system
(1 = susceptible, 9 = resistant).

How a corn plant develops: Growth and
development through the vegetative stages
All corn follows a similar pattern of development with variations based on hybrids, seasons, planting dates and locations. This
illustration shows the key phases of corn development through the vegetative (V) stages.

to emerge. The growing
point (stem apex) is 1
to 1.5 inches below the
surface. The seminal root
system is growing from
the seed. The seminal
roots do much of the early
work, but growth slows
after VE as nodal roots
begin to grow.
20
V6 Stage
V9 Stage
The growing point and
tassel rise above the soil
surface at about the V6
stage. The stalk begins
to elongate. The nodal
root system grows
from the three to four
lowest stalk nodes. Some
ear shoots or tillers are
visible. Tiller (or sucker)
development depends on
the specific hybrid, plant
density, fertility and
other conditions.
Dissection of a V9 plant
shows many ear shoots
(potential ears). These
develop from every aboveground node except the
last six to eight nodes
below the tassel. Lower ear
shoots grow fast at first,
but only the upper one or
two develop a harvestable ear. The tassel begins
to develop rapidly. Stalks
lengthen as the internodes
grow. By V10, the time
between new leaf stages
shortens to about every
two to three days.
V12 Stage
V15 Stage
V18 Stage
VT Stage
The number of ovules
(potential kernels) on
each ear and the size of
the ear are determined
at the V12 stage. The
number of kernels per
row isn’t determined
until about a week before
silking, at about V17.
The top ear shoot is still
smaller than the lower ear
shoots, but many of the
upper ears are close to
the same size.
This is the start of the
most crucial period for
determining grain yield.
Upper ear shoot development overshadows lower
ear shoot development.
Every one to two days, a
new leaf stage occurs.
Silks begin to grow from
the upper ears. By V17,
the tips of upper ear
shoots may be visible
atop the leaf sheaths. The
tip of the tassel also may
be visible.
Silks from the basal ear
ovules elongate first. Silks
from the ear tip ovules
follow. This illustration
represents about eight to
nine days of reproductive
organ development.
Brace roots (aerial nodal
roots) grow from the
nodes above the soil
surface to help support
the plant and take in
water and nutrients
during the reproductive
stages.
The VT stage arrives
when the last branch of
the tassel is completely
visible. VT begins about
two to three days before
silk emergence. The plant
is nearly at its full height.
Pollen shed begins, lasting
one to two weeks. The
time between VT
and R1 can fluctuate
considerably depending
on the hybrid and the
environment.
21
How a corn plant develops:
Reproduction through maturity
R1 stage: Silking
The R1 stage begins when silk
is visible outside the husks.
Pollination occurs when these
moist silks catch falling pollen
grains. Pollen takes about 24 hours
to move down the silk to the ovule
where fertilization occurs. The
ovule becomes a kernel. Generally,
all silks on an ear are pollinated in
two to three days. The silks grow
1.0 to 1.5 inches each day until
fertilized. The R1 kernel is almost
engulfed in cob materials and is
white on the outside. The inner
material is clear with little fluid
present.
22
R2 stage: Blister
(10-14 days after silking)
R3 stage: Milk
(18-22 days after silking)
R2 kernels are white on the
outside and resemble a blister. The
endosperm and its nowabundant inner fluid are clear. The
embryo is still developing, but it
now contains a developing miniature corn plant. Much of
the kernel has grown out from
the surrounding cob materials. The
cob is close to full size. Silks are
darkening and beginning to dry
out. Starch has just begun
to accumulate in the watery
endosperm. Kernels are beginning
to accumulate dry matter.
Seed-fill is beginning.
The R3 kernel is yellow outside,
while the inner fluid is now milky
white due to accumulating starch.
The embryo is growing rapidly.
Most of the R3 kernel has grown
out from the surrounding cob.
Silks are brown and dry or
becoming dry.
R4 stage: Dough
(24-28 days after silking)
R5 stage: Dent
(35-42 days after silking)
Continued starch accumulation
in the endosperm causes the
milky inner fluid to thicken to a
pasty consistency. Usually four
embryonic leaves have formed
as the embryo has grown
dramatically from the R3 stage. The
shelled cob is a light red to pink.
Toward the middle of R4, the
embryo will stretch across more
than half of the width of the kernel
side. Just before R5, kernels along
the length of the ear begin to dent
or dry. The fifth (last) embryonic
leaf and the lateral seminal roots
have formed. If this seed is planted,
these five embryonic leaves will
appear the following season after
germination and VE.
At R5, all or nearly all kernels
are dented or denting. The shelled
cob is dark red. The kernels are
drying down from the top, where
a small hard layer of starch is
forming. This starch layer appears
shortly after denting as a line
across the back of the kernel (the
non-embryo side). With maturity,
the hard starch layer and line
will advance toward the cob.
Accumulated starch is hard above
the line but still soft below the line.
R6 stage:
Physiological maturity
(55-65 days after silking)
By the R6 stage, kernels have
attained their maximum dry
weight or dry matter accumulation.
The hard starch layer has
advanced completely to the cob.
A black or brown abscission layer
forms, moving progressively from
the tip ear kernels to the basal
kernels of the ear. It’s a good
indication of physiological
maturity and signals the end of
kernel growth. The husks and
many leaves are no longer green,
although the stalk may be.
23
Match Hybrid Maturity
to Available CHUs
In Western Canada, especially in areas new to growing corn, it is very important that the maturity of your selected hybrid
matches the available growing period. Growers should make hybrid selections that correspond to the corn heat unit (CHU)
