Though controls are limited, all
factors affecting yields must be
known to evaluate intensive
management systems.
Weed control
-Control weeds. In winter
grains, control is available in fall
and in spring. Alley says fall
control is superior because it
lessens competition and potential
damage to the crop. “I like to see
control in the fall with a
bromoxynil application,” Alley
explains, “because there is less

potential for damage than with

-Carefully manage nitrogen.
Raws and timing are critical to
high yields; in Europe rates are as
high as 200 kg/hectare (178 lbs.
N/acre) and timing is between
growth stages five and six, or near
the time the first node of the stem
is visible. But even in Europe the
amount and timing of nitrogen is a
debated point-the system is not
yet perfected.
The basic change in nitrogen
recommendations, Alley sees, is
the application of the single largest
amount of N at jointing, or stem
elongation. In Virginia tests with
120 pounds of spring-applied N,

yields have been increased by
splitting. Nitrogen management
work is continuing but our
research group currently believes
that the major spring N ap
plication should be near the
jointing stage with the late winter
application adjusted to promote
any needed tillering,” Alley says.
“That is, 30-40 lbs. N/acre would
be applied during tillering if the
population is adequate, or this
would be increased to 60 lbs.
N/acre if the population is not
adequate.”
Growth regulator
The goal is 600-700 head-bearing
tillers per square meter at harvest
and judgment may allow for need
to stimulate tillering. “A major
point of fertilization,” says Alley,
“is that high-yielding wheat cannot
be produced just by increasing the
N and especially not by applying
large amounts of N at tillering.
Management of the nitrogen is
essential to avoid lodging and
unnecessary input costs.”
-Use a plant growth regulator to
control lodging. Increased
nitrogen levels, residual nitrogen
on rotated fields, and weather
conditions all can contribute to a
lodged gram crop. “Management
of all inputs does not include just
increasing nitrogen and expecting
a plant growth regulator like
Cerone (TM) ethephon to control
lodging. The plant growth
regulator has a place in the in
tensive management system,”
says Alley, “to regulate plant
height and strengthen wheat
stems, making the stand more
resistant to lodging."
Europeans apply even higher N
rates and get lodging control with a
plant growth regulator, Alley says
of his observations in England,
France and Germany. But their
soils are not super where they are
producing the high yields and
that’s encouraging to me....1f they
can grow 10-ton crops on those
soils, we can too.” - And that
would be a 150-bushel per acre
wheat crop!
