1994 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
early-planted, 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.
Beginning in 1994, standard corn performance
tests were divided into groups based on hybrid
maturity. The early group included hybrids with
110 or fewer days to black layer. The medium
group included hybrids with 111-115 days to
black layer. Hybrids listed as greater than 115
days to black layer were included in the late
group. This minimizes competitive effects caused
by maturity and emphasizes comparisons
between hybrids of similar maturity. Maturity
groupings were made within each replication to
provide valid comparisons between hybrids within
a maturity group and between hybrids in different
maturity groups.
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 1994 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 1994 and normal. All graphs
include vertical lines indicating planting, silking,
and harvest date 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 1-15 contain
results from individual locations of the standard
corn performance tests. A yield summary (Table
16) presents yields as a percent of the average
for each maturity at each location. Tables 17-22
contain results from the short-season tests.
Table 23 lists yields expressed as a percent of
the test averages from the short-season tests.
The 1994 entrants, entries, and some additional
descriptive information are listed in the Appendix.
In most tests, corn was planted at a heavy rate
and thinned to desired populations several weeks
after planting. This reduced the chance that seed

vigor and germination of particular seed lots
might influence yield and increased the
probability that genetic yield potential would be
measured instead. Some short-season tests
were planted to stand with no thinning.
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
design. In most of the standard tests, hybrids of
similar maturity were grouped with each other in
each replication.
In two tests (Greeley Co.
dryland and Thomas Co. dryland), four-row plots
were used and hybrids of all maturities were
randomized within each block. 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.
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). In tests with
maturity groupings, percent of test average was
calculated using the average of each group rather
than the average of the entire test. Hybrids
yielding more than 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.
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, but the
level of lodging and ear droppage was very low in
most tests, minimizing this potential problem.
Percent GREEN BREAK is reported for some
tests. This is an estimate of the percent of plants
broken off prior to grain filling and senescence.
Most of the green break in 1994 was related to a
July 1 windstorm that moved through northcentral and northeast Kansas.
Relative maturity is measured in terms of both
GRAIN MOISTURE AT HARVEST and NUMBER
OF DAYS FROM PLANTING TO SILKING at
most locations. Relative moisture at harvest
usually is a better maturity indicator, unless
harvest is delayed. Hybrids are listed first from
lowest to highest grain moisture and then from
fewest to most days to silking within each
moisture level. This emphasizes the maturity
differences of the hybrids in addition to yield
performance.
Maturity can be critical when
considering a corn hybrid for a specific cropping
system.
The GROWTH UNIT or GROWING DEGREE
DAY concept was developed to measure the
amount of heat available for growth and
maturation. The formula used to generate the
monthly totals in individual test discussions
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.
Small differences in yield or other characteristics
should not be overemphasized. Least significant
differences (L.S.D.'s) are shown at the bottom of
each maturity group for comparisons within that
group and at the bottom of each performance test
table for comparisons between maturity groups.
Be sure to use the correct L.S.D. for the
comparison of interest. Unless two entries differ
by at least the L.S.D. shown, little confidence can
be placed in one being superior to the other. The
coefficient of variability (C.V.) can be used to
estimate the degree of confidence one may have
in published data from replicated tests. In this
testing program, C.V.'s below 10% generally
indicate reliable, uniform data, whereas C.V.'s of
-2-

10 to 15% are not uncommon and usually
indicate that data are acceptable for the rough
performance comparisons desired from these
tests. Tests with C.V.'s over 15% still may be
useful, but hybrid comparisons lack precision.
1994 STATEWIDE GROWING CONDITIONS
Favorable growing conditions over most of the
state made 1994 a record-setting year. After a
warm March, April's below-normal temperatures
slowed initial growth. Replanting was necessary
in the southeast after heavy rains in mid-April and
in other areas after late-April freezes. Many other
fields suffered freeze damage but were able to
recover without replanting. Warm temperatures
enabled rapid vegetative growth during May and
June. Surface soil moisture was short over much
of the state in late May and early June, but
subsoil moisture was usually adequate during
that time period. Cooler temperatures and timely
rains in July and August facilitated good seed set,
setting the stage for high yields. Harvest was
underway in early September. Clear weather
during most of September and October enabled
farmers to harvest the crop under ideal
conditions. All of the crop was out of the field by
mid-November, well ahead of the 5-year average.
For most of the season, nearly 99% of the crop
was rated fair or better. From late July through
the end of the season, 75% or more of the crop
was rated good or excellent except for one report
at the end of August. (From Crop-Weather
reports, Kansas Agricultural Statistics, Topeka.)
The usual complement of insects was found in
Kansas corn fields in 1994. Wireworms caused
some seedling damage in south central fields.
Cutworms damaged areas within fields in eastern
Kansas. European corn borers began showing
up in late May in the east. This pest was often
present, but typically not in damaging
populations. Southwestern corn borers caused
damage in many south central corn fields, but
were present in relatively light populations in
southwestern and western areas. Spider mite
infestations reached treatment levels in the
southwest in July. Treatment for this pest moved
north in subsequent weeks.
Western corn
rootworms occasionally damaged fields in
western Kansas. (Insect information from
Cooperative Economic Insect Survey Report,
Kansas State Board of Agriculture.)
Disease damage was light across most of the
state this year. Some damping off was noted
early in the season. The April freezes may have
made these fields more susceptible to this
disease. Foliar diseases such as common maize
rust, viral mosaic, Stewart's wilt, northern leaf
blight, and gray leafspot were present, especially
in central and eastern areas, but caused little
large-scale damage. Rapid maturation of the
corn crop in late August further limited the
potential damage from these diseases. High
Plains tenui virus was found in association with
wheat streak mosaic virus in mid July in a field
near St. John. By late July, the disease was
noted at several locations scattered across
western Kansas. In mid-August, American wheat
striate mosaic was found for the first time in corn
in Kansas. Toward the end of the season,
charcoal rot was found in some fields. Several
ear rots also were noted, especially in the
southeast. These included Rhizopus ear rot,
Fusarium kernel rot, Cladosporium, and
Penicillium ear rot. (Disease information from
Plant Disease Survey Report, Kansas State
Board of Agriculture.)
The November 9 Kansas Agricultural Statistics
report predicted a record 321.0 million bushel
crop, up 49 percent from 1993. This production
is from 2.14 million harvested acres, up 340,000
acres from last year. The predicted average yield
of 150 bushels per acre matches the record set in
1992. (From Crops Report November 9, Kansas
Agriculture Statistics.)

1994 GROWING CONDITIONS:
All hybrids established good stands and produced
acceptable yields. Timely rainfall and a full soil
profile from last year's rains prevented poor yields
during a growing season characterized by several
extended dry periods at this location. Disease and
insect damage was minimal.

1994 GROWING CONDITIONS:
This test emerged somewhat slowly, but good stands
eventually were established. Some plants broke off
during the July 1 windstorm, but the lodging listed in
the table occurred later in the season. Yields were
quite good for dryland corn at this location.

1994 GROWING CONDITIONS:
This test looked good until the July 1 windstorm.
Plot yields for the early group were so variable that
no yield estimates were obtained. Green break was
not correlated to yield, but it did introduce additional
variability and likely reduced yields. Please keep
this in mind when examining the results from this
test.

1994 GROWING CONDITIONS:
This test was off to a good start when it was severely
damaged by a windstorm just prior to silking in early
July. The damage was so extensive that yields were
determined more by the level of breakage than by
the hybrids' performance potential. For that reason,
no yield data for 1994 are presented in the table.

1994 GROWING CONDITIONS:
April rains delayed planting of this test by nearly a
month. Growing conditions were favorable for most
of the season with no visual evidence of moisture
stress. Severe winds in early June caused many
plants to lean severely, but most of these plants
recovered with little permanent damage. The
medium group had the highest yields, but differences
between hybrids within this group were not significant
according to statistical tests.

SILK DATES:
1994 GROWING CONDITIONS:
This test was planted originally on April 4, but 9
inches of rain on April 11 caused flooding of the test
site. After replanting, conditions were favorable for
outstanding corn yields. Two early hybrids were
damaged severely by raccoons. Several other
hybrids suffered only occasional damage.
Undamaged portions of the affected plots were
harvested to provide yield estimates that reflected
hybrid performance rather than raccoon preference.
Leaf rust was noted late in the season but probably
reduced yields very little.

1994 GROWING CONDITIONS:
The hybrids in this test performed very well thanks to
above-normal rainfall in June and July. August and
September were relatively dry, but stored soil
moisture was sufficient to produce outstanding yields
for hybrids of all maturities. Insect and disease
damage was inconsequential.

1994 GROWING CONDITIONS:
Aside from a July 1 windstorm, this test experienced
excellent growing conditions. Yields for eight hybrids
that suffered severe green break during that storm
are not reported. All other hybrids had little or no
long-term damage from that storm. August
irrigations helped to maintain leaf tissue during dry
weather and extended the grain filling period.

* L.S.D. for comparing hybrids within a maturity grouping.
** L.S.D. for comparing hybrids in different maturity groups.
Unless two varieties differ by more than the L.S.D., little confidence can be placed in one being superior to the other.
Yields of 8 hybrids with severe green break from the July 1 windstorm are not reported. Yield estimates for
these hybrids were not included in the summary statistics or analysis.

1994 GROWING CONDITIONS:
The test was planted into 1993 wheat stubble. Some
rows that fell directly on last year's wheat rows were
delayed in germination and emergence. This likely
contributed to variability in final yields. However,
yields in general were excellent for dryland corn
production at this location because of above-normal
precipitation through July. Hot, dry, windy conditions
in August and September prevented even higher
yields. (Weather data and graphs presented with
irrigated test information, page 31.)

1994 GROWING CONDITIONS:
Above-normal precipitation in June and July enabled
even the full-season hybrids to set seed and produce
excellent yields for this dryland location. Yields for
short-season check C4327 are not included because
of extensive raccoon damage.

1994 GROWING CONDITIONS:
All hybrids established good stands and produced
adequate yields. As might be expected under
irrigation in a normal growing season, the early
hybrids yielded less than the medium or late hybrids.
Little difference in yield occurred between the
medium and late groups, although the medium group
had lower grain moisture and higher test weight
averages. Insect and disease damage was minimal.

EAST CENTRAL KANSAS
SHORT-SEASON CORN TEST
ON SILT LOAM SOIL
LOCATION: East Central Kansas Experiment Field
South of Ottawa in Franklin County
COOPERATORS: Keith Janssen, agronomist
Edwin Horstick, technician
TEST SITE: Woodson silt loam
Soybeans in 1993, corn in 1992
FERTILIZATION: 102 lbs N/acre preplant
48 lbs P2O5/acre preplant
24 lbs K2O/acre preplant
PLANTING DATE: April 20
SILKING DATES: June 27 - July 5
HARVEST DATE: September 15
PEST CONTROL: Good
Bicep herbicide
POPULATION:
Desired:
20,000 plants/acre, 10.5 in. spacing
Thinned:
Overplanted by 10%, not thinned
Final stand:
88% of desired
TEST YIELDS: Slightly variable
Average:
92 bu/acre
Range:
47 to 121 bu/acre
L.S.D.:
15.4 bu/acre
C.V.:
11.9%
1994 GROWING CONDITIONS:
Heavy rain and cold temperatures after planting
reduced emergence and final stands for some
hybrids. Those hybrids with lower stands tended to
have lower yields as well. Dry weather during May
and late June reduced yield potential. A windstorm
in early June caused most plants to lean severely.
Most hybrids were fully mature by mid to late August.
(Weather data and graphs presented with standard
test results, page 17).

1994 GROWING CONDITIONS:
Several conditions contributed to high yield
variability. An April freeze killed the plants to the soil
surface, delaying early-season growth. Moisture and
heat stress during silking and pollen shed prevented
full pollination of several hybrids. Continued
moisture stress later in the season caused severe
ear drop for some hybrids. For these reasons, 1994
yields are not reported.

IRRIGATION:
1994 GROWING CONDITIONS:
The test was planted originally on April 15, but
freezes in late April caused sufficient stand loss to
necessitate replanting. Final stands in the second
planting were 12-27% lower than the target stand.
However, stands for all hybrids were within 10% of
the average. Stand differences likely contributed
little to hybrid yield differences. The growing season
was very hot and dry. Infestations of southwestern
corn borer and european corn borer may have
contributed to some of the lodging.
(Weather data, graphs, and growing conditions
presented with standard test, page 27).

Excerpts from the
UNIVERSITY RESEARCH POLICY AGREEMENT WITH COOPERATING SEED COMPANIES*
Permission is hereby given to Kansas State University to test our varieties and/or hybrids designated on
the attached entry forms in the manner indicated on the test announcement. I understand that all results
from Kansas crop performance tests belong to the University and to the public and shall be controlled by
the University so as to produce the greatest benefit to the public. It is further agreed that the name of the
University shall not be used by the company in any commercial advertising either in regard to this
agreement or any other related matter.
* This agreement must be signed by an authorized individual before results involving the company's
entries can be published by the Experiment Station. Except for the limitation that the name "KANSAS
STATE UNIVERSITY" cannot be used in advertising (you may use something like "official state tests" or
"state yield trials"), this does not preclude the use of data for advertising, if done in a fair manner.
