DEKALB, 111. By the time
' com plants are shoulder high
they’ve formed all the potential
kernel sites they’ll ever have,
claims Wayne Fowler, Agronomic
Education Director for DEKALB.
“Management for high yield
strives to maintain, first, high
kernel survivaT and, second, full
“fill” of the survivors,” states
Fowler. "Afterall, grain yield is
the product of how many kernels
end up in the bin and how much
each one weighs.”
Considermg everything that’s
necessary for a plant to live and
reproduce successfully, it’s a
wonder it works so well.
The products of photosynthesis
have to be moved about in the
plant, destroyed and reformed—in
some cases several times—to form
roots, stalks, leaves, cobs, husks,
silks, pollen, and (finally) grain.
The process has to be maintained
for 120 to 140 days in order to
develop kernels to the maximum
weight. „ ,

What affects corn kemal numbers?
Timing of events in relation to
plant development is very im
portant. An early planted field
might'be adversely affected by
early drought while a later planted
field of the same hybrid escapes
because rains came.
Conversely, the early field might
be far enough advanced to be little
affected by a stress condition that
proves to be severe to a later field
with younger plants. Two hybrids
planted the same day and growing
under .the same conditions are not
necessarily in exactly the same
stage of development at any given
time.
The nature of kernel develop
ment on an individual ear is that
those toward the tip are the last to
develop, hence the youngest. Plant
stress will cause abortion of
kernels at the ear tip, starting with
the very youngest. The more
severe or long lasting the stress,
the greater number of aborted
kernels.
OPEN HOUSE
This abortion of young kernels
occurs because plants have been
unable to translocate sufficient
products of photosynthesis to the
ear. There are many reasons why
this may occur, including nutrient
availability, soil pH, soil moisture,
temperature, liphr and others.
NEWARK, Del. - As cold
weather heads this way, the season
for pesticide use is over for most
people. Leftover pesticides should
be stored properly so they’ll
present no hazards and will be fit
for use next season. .Improperly
stored pesticides can contaminate
animals, food, feed; or fertilizers.
Be sure each pesticide container
has a proper label before you store
it, says John McDaniel, Extension .
pesticide specialist. Reading this
label is the only safe way to know
which pesticide is in the container.
It carries the precautions and

A final comment of Fowler’s that
may be pertinent this fall in areas
where growing conditions have
been favorable: there may be
some concern about unexpected
“poor tip fill.” “This may simply
be due to continued cob growth and
directions needed to use the
product properly.
Do not store leaky containers,
and be sure all caps are tightened
securely. Weed killers should not
be stored near other pesticides or
fertilizers. Vapors escaping from
them may be absorbed by other
pesticides or fertilizers and
damage next year’s plants when
the contaminated pesticide is used.
The storage area should be cool,
dry, and secure. The ideal storage
place is a locked room or cabinet,
safely out of reach of children and
other non-suspecting people and

animals. Certain pesticides should
not be stored where the tem
perature is apt to drop below 40
degrees Fahrenheit, points out
McDaniel. Below this point some
pesticide products separate and
cannot be mixed. Excessive heat
can cause other pesticides to
decompose.
After the pesticides are carefully
put away for the winter, prepare
the sprayer for storage. For power
equipment follow the manufac
turer’s suggestions. A hand
sprayer should be rinsed inside
and out, and sprayed through with
dear water. Oil the leathers in the

with the pump out of the tank. Hus
