Corn standability can be improved

frequently ask why one hybrid will
stand through harvest while
another across the fence suffers
lodging and is difficult to harvest.
Cora plant standability is a

Physical influences are easy to
determine, since the damage can
be seen and examined.
Physiological stresses are more
difficult to assess since most of
them occur inside the paint and the
contributing factors are complex.
Items that can cause physical
stress to a corn plant include
things such as insects, hail, wind,
and (indirectly) herbicides. In
sects or hail can cause cavities in
the plant and reduce the stalk’s
structural strength. As the plant
matures and begins to dry down, it
naturally losses some of its
strength.
If, in addition, a borer or hail
mark has destroyed part of the
stalk, the plant may not hold itself
up under the weight of the ear or in
a wind. Stalk rind thickness and
strength is one trait that resear

potassium (K) and nitrogen (N)
levels are two commonly noted
areas. When K levels are
adequate, thicker cell walls form,
stomata are open longer, and the
plant operates more efficiently.

to let it reach its top yield potential
and maintain plant standabllity.
The pathogens commonly
associated with stalk rot are
Fusarium, Gibberella, and
Diplodia. They serve a natural
purpose of decomposing organic
matter and freeing the nutrients
for the succeeding years’ crop.
They don’t cause a problem as long
as they do their job after the crop is
harvested. They will invade and
cause deterioration in plants
already under stress.

through three retail outlets as well
as a five-state truck distribution
system. In fiscal 1963-84 Eastern’s
Dairy Products Division achieved
approximately $6.1 million in gross
sales.
“The new warehouse complex is
yet another indication of Eastern’s
commitment to the future,” said
Forwood. “Eastern is in a strong
position now and will continue to
grow in the years ahead.”
The new retail outlet occupies
the front section of the recently
completed complex. Eight persons
have been hired to staff the new
facility which will feature Penn
sylvania and New York
agricultural products as well as
milk shakes, sandwiches and ice
cream.
Bruce Buck has been named
manager of the store and
warehouse. Debbie Issacs will
serve as assistant manager.
“A gala grand opening is
planned for the warehouse com
plex” said Forwood, “The date of
this event will be announced
sometime in the future.”
