1996 KANSAS CORN PERFORMANCE TESTS
INTRODUCTION
TEST OBJECTIVES AND PROCEDURES
Corn Performance Tests, conducted annually by
the Kansas Agricultural Experiment Station,
provide farmers, extension workers, and private
research and sales personnel with unbiased
agronomic information on many of the corn
hybrids marketed in the state. Entry fees from
private seed companies help finance the tests.
Seed companies receive test announcements
and entry forms in late January each year;
deadlines for receipt of completed entry forms
and seed are in early March. Because entry
selection and location are voluntary, not all
hybrids grown in the state are included in tests,
and hybrids are not grown uniformly at all test
locations.
In 1992, several short-season corn performance
tests were added. Procedures for these tests
were similar to those for the full-season tests,
except where noted. This series of tests targets
evaluation of corn hybrids for use in earlyplanted,
short-season,
cropping
systems.
Hybrids with adequate heat and drought
tolerance are needed for these systems. These
hybrids often will be subjected to severe heat and
drought stress in July and August.
These
systems typically are utilized on soils with poor
water-holding capacities. Early-maturing hybrids
often are able to escape a good portion of the
typical stress if they can be planted early.
Utilization of short-season hybrids under irrigation
often is related to the desire to reduce irrigation
inputs or to facilitate specific crop rotations.
A summary of growing-season weather data is
given in individual test discussions. These data
are from the nearest weather-reporting station
and often are supplemented with information
from the test site. Precipitation graphs include
cumulative lines for 1996 and the 30-year normal
in addition to the daily rainfall amounts since last
fall. Temperature graphs include daily maximum
and minimum temperatures compared with
normal.
Growing degree graphs include
cumulative lines for 1996 and normal. All graphs
include vertical lines indicating planting, silking,
and harvest dates, if available. General trends in
precipitation and rainfall relative to normal are
readily observed in the graphs.
For more
detailed information, a table is included with
monthly totals and averages for the growing
season.
Comparisons of the current year's
weather with long-time averages often help
explain unusual plant development patterns and
inconsistent performance of individual hybrids
over years.
Explanatory information is given preceding data
summaries for each test. Tables 1-14 contain
results from individual locations of the standard
corn performance tests. Hybrids are no longer
separated into groups based on hybrid maturity
because of the difficulty in accurately assigning a
maturity class before the growing season.
Rather, hybrids are now listed in order of
increasing days to half silk and increasing grain
moisture for the current year so hybrids of similar
maturity appear together.
A yield summary
(Table 15) presents yields as a percent of the
average for each location. Tables 16-18 contain
results from the short-season tests. Table 19
lists yields expressed as a percent of the test
averages from the short-season tests. The 1996
entrants, entries, and some additional descriptive
information are listed in the Appendixes.
Beginning in 1995, most corn tests were planted
at a rate 10% to 20% above the desired
population and only minimally thinned. Planting
to stand enables evaluation of product
performance for the entire growing season. The
performance of the marketed product includes
stand establishment as well as genetic yield
potential.
Tractor-powered, modified, White air-planters
were used for nearly all tests. Except for the
Finney County test where space was limited, four
plots (replications) of each hybrid were grown at
each location in a randomized complete block

1996 STATEWIDE GROWING CONDITIONS
Generally favorable conditions during the critical
parts of the growing season set the stage for a
record corn crop. The season started out with
low soil moisture, but timely rains during the
remainder of the summer provided sufficient
moisture for high yields in much of the state
(Figure 1).

comparison of hybrids of like maturity. Maturity
can be critical when considering a corn hybrid for
a specific cropping system.

The number of LODGED and DROPPED EARS
is reported, when appropriate. Plants broken over
below the ear were considered LODGED,
although many were harvestable with modern
machinery. Severely lodged stalks or dropped
ears that could not be picked up by normal
harvest procedures are not included in yield.
Because harvest often is delayed until latest
maturing entries are ripe, early and mid- season
hybrids could lose ears simply because they must
wait well past their optimum harvest date. In
most years, dropped ears do not significantly
affect yields.
Small differences in yield or other characteristics
should not be overemphasized. Least significant
differences (LSD's) are shown at the bottom of
each table. Unless two entries differ by at least
the LSD shown, little confidence can be placed in
one being superior to the other. The coefficient of
variability (CV) can be used to estimate the
degree of confidence one may have in published
data from replicated tests. In this testing program,
CV's below 10% generally indicate reliable,
uniform data, whereas CV's of 10 to 15% are not
uncommon and usually indicate that data are
acceptable
for
the
rough
performance
comparisons desired from these tests. Tests with
CV's over 15% still may be useful, but hybrid
comparisons lack precision.

GRAIN YIELDS are reported as bushels per acre
of shelled grain (56 lbs/bu) adjusted to a moisture
content of 15.5%. BUSHEL YIELDS are given
but also are converted to YIELDS AS
PERCENTAGES OF THE TEST AVERAGE to
speed recognition of highest-yielding hybrids
(more than 100%, the test average). The actual
test average in bushels per acre is listed as the
test average in the YIELD AS % OF TEST
AVERAGE columns as a guide to actual yields.
Hybrids yielding more than 100% of the test
average year after year merit consideration, but
adaptation to individual farms for appropriate
maturity, stalk strength, and other factors also
must be considered.
follows: Take the maximum temperature plus the
minimum temperature for each day, divide by 2,
and then subtract a base temperature of 50 each
day. Any temperature below 50F was considered
to be 50, and any temperature over 86F was
called 86. Growth unit accumulations for the
current year are compared with the long-term
average or 'normal' for each test.

design. In one test (Thomas Co. dryland), fourrow plots were used.
Each harvested plot
consisted of two rows trimmed to a specific
length ranging from 20 to 45 feet at the different
locations. Tests were harvested with Gleaner-E
combines equipped with automatic weighing and
sampling devices.

Most of the crop experienced favorable
conditions during the bulk of the growing season.
At all times, at least 55% of the crop rated good
or excellent, and from July on, over 80% was in
those categories (Figure 2).
Warm temperatures early in the summer enabled
timely planting and caused rapid growth and
development.
However,
relatively
cool
temperatures in August slowed maturation and
dry down. As a result, harvest was later than it
was in 1995 even though crop development had
been ahead of last year for much of the season.

Figure 2. 1996 Corn crop condition.
Although other insect pests were present in
1996, most of the damage was done by the same
insects that typically cause problems for the
Kansas corn crop. Occasional fields suffered
serious cutworm damage, but injury was not
widespread. European corn borer moths began
appearing in early June in eastern Kansas.
Southwestern corn borer moths appeared in midlate June in south central and southwest Kansas.
First-generation populations of both pests
appeared lighter than normal, but the second
generation tended to be more plentiful and to
cause more damage. Growers in south central
and southwestern areas treated many fields.
Corn rootworms caused serious damage in some
southwestern fields in July.
Spider mite
populations increased in many western fields;
however,
natural
predators
often
kept
populations in check.

Disease problems were above normal in the
1996 Kansas corn crop. Frequent rains in May
caused significant amounts of Pythium seedling
blight in many parts of the state. Additionally,
eastern Kansas corn less than 12 inches in
height was plagued by yellowing leaves and
crown decay problems. The cause was identified
as oxygen deprivation and was associated with
continuously wet soils. Corn plants less than 12
inches in height have a low tolerance to wet or
flooded soils. Significant levels of gray leaf spot
developed in many fields in northeast, south
central, and southwest Kansas. Many fields
reached economic treatment levels and required
spraying. Known areas of infestation spread at
least 90 miles westward in 1996, with known
outbreaks as far west as Lakin in southwest
Kansas and Kensington in northwest Kansas.
Stalk rot levels were generally low, but some hot
spots developed around the state. The areas in
extreme northeast and southwest Kansas that
had significant gray leaf spot problems also
developed significant levels of anthracnose stalk
rot. Fusarium stalk rot problems occurred in
many fields affected by the early season crown
damage.
ACKNOWLEDGMENTS
Cooperation of Research Center and Experiment Field
personnel who furnished land and performed many or
all of the field operations is sincerely appreciated.
Technicians Edward O. Quigley and James R.
Cochrane packaged seed and performed field
operations for some of the tests. Student workers
Linsay Allison and Matt Franko helped with seed
counting, sign painting, and plot maintenance. Mary
Knapp of the Weather Data Library provided much of
the
climatological
information.
Ear mold levels were above average as well in
1996. Aflatoxin development, caused by the
fungus Aspergillus flavus, has been reported
primarily from northeast Kansas, but also from
southeastern areas. Gibberella, Fusarium and
Diplodia ear rots also have been frequent, with
several reports coming in from both southwest
and northwest production areas. These molds
are associated with the frequent rains and hail
damage that occurred in many areas during the
grain filling period. Gibberella and Fusarium can
produce vomitoxin and zearalenone, and feeders
should test suspect grain for toxins especially if
destined for swine feeding. (From Doug Jardine,
Extension Plant Pathologist, Kansas State
University Department of Plant Pathology.)
The October 11 Kansas Agricultural Statistics
report predicted a record 340.8 million bushel
crop, up 39% from 1995. This production is from
2.35 million harvested acres, up 19% from last
year. The predicted average yield of 145 bushels
per acre is 21 bushels above that in 1995. (From
October 11 Crops Report, Kansas Agriculture
Statistics.)

Good planting conditions resulted in good stands, but
heavy May rains slowed early growth. The rest of the
season was ideal for corn production, with adequate heat
and timely rains. Gray leaf spot and possibly anthracnose
moved in late in the season and may have decreased
yields slightly.

Good moisture at planting resulted in generally good
stands. Ideal growing conditions prevailed for most of the
season. A wind storm on July 8 when the corn was silking
caused most of the root lodging noted in the table.

Rainfall immediately following planting caused some
uneven emergence, but early season growth was generally
good. Excellent growing conditions combined with the
deep, river-bottom soils resulted in high yields. Some corn
borer damage below the ear caused scattered lodging.
However, most lodging was due to weak stalks and wind
damage.

Favorable planting conditions resulted in good stands.
Initial dryness in April gave way to good precipitation in
May. Dry conditions returned in June, but good rainfall in
July and August helped the test produce outstanding
dryland yields. Diseases and insects presented no
problems.

Favorable planting conditions resulted in excellent stands.
A preirrigation to fill the soil profile was required because
of the very dry spring. The relatively cool, wet summer
minimized the need for later irrigations. Warm
temperatures in September and October facilitated
complete grain fill and excellent yields.

Early irrigations helped stand establishment and early
growth. Above-normal rainfall during May, July, and
August minimized the need for late-season irrigation.
Corn borer damage likely caused some of the noted
lodging.

Cool soils delayed planting somewhat and may have
slowed emergence. Soil conditions were dry at planting.
Heavy rains alternated with dry periods for most of the
growing season. The test did not appear to be subjected
to moisture stress. The precipitation received at silking
around July 4 enabled the test to produce decent grain
yields.
