Figure 2. Condition of 2006 Kansas corn crop.
Some southern rust developed to high levels in many
parts of the state, but generally came in late enough that
yields were not sufficiently threatened to require
spraying.
Charcoal rot was prevalent in parts of the state where
corn was under more severe drought stress. Where the
corn died prematurely, saprophytic molds began to
develop on the dead plant tissue once the rains began,
giving the plants a blackened appearance. This resulted
in many “black clouds” following the combines.

Statewide Growing Conditions
The 2006 growing season started under less-than-ideal
conditions, when scattered rains in late March did not go
far toward alleviating the topsoil moisture deficit in 95%
of the acreage in the state (Figure 1). April, May, and
June were generally hot, dry and windy, although some
areas did receive isolated showers. Extended dry and
very hot periods in July and early August severely
stressed the corn, causing premature death or early
cutting for forage in many cases. Late-August rains and
cooler temperatures helped later-maturing fields, but
provided little benefit to the portion of the crop that had
already matured.
Figure 1. Statewide status of topsoil moisture.
The condition of the corn crop was closely tied to the
pattern of precipitation (Figure 2). Corn that was
classified as good to excellent was mostly concentrated
in the southeast portion of the state that received isolated
showers throughout the growing season. Fields in the
west and southwest were typically the most severely
stressed. The condition of all of the corn throughout the
state declined from late June until August during the
extended hot and dry period. As harvest was under way
in October, 68% of the crop was classified as fair to very
poor. (Crop-Weather Reports, Kansas Agricultural
Statistics, Topeka)
Diseases
The condition of the 2006 crop was somewhat dependent
on where the corn was grown in the state. Southeastern
Kansas had excellent growing conditions until the end of
the season and had little disease pressure. Where
environmental stress was high, such as in southwestern
Kansas, stalk rots developed late in the season, even in
irrigated corn. Because of the severity of stalk rot across
the state, disease losses were above the long-term
average.
There were scattered reports of gray leaf spot and ear
molds in the state. Some fields had aflatoxin above
threshold levels, but this was not widespread. Several
samples of Diplodia ear rot were received in the Plant
Disease Diagnostic Lab. These samples generally
originated from the northeastern part of the state.
(Doug Jardine, Kansas State University Department of
Plant Pathology)
Insects
Few early-season problems were noted. No reports of
black cutworms or European corn borers were received.
Corn rootworm populations were about average. Second
generation European corn borer infestations were more
evident in 2006 than in the previous five years, but still
remained low. Second-generation southwestern corn
borers and spider mites continued to cause problems in
southwestern Kansas. Southwestern corn borers have
successfully over wintered in north-central Kansas since
1999, and have started to cause considerable concern in
that area. Whether they will continue this overwintering success throughout the state remains to be
determined.

Entomology)

Harvest Statistics
The October 12 Crops Report predicted a 387.5-millionbushel crop, down 17% from last year (Figure 3). In
2006, 3.15 million acres were harvested, down 9% from
2005. The predicted average yield of 123 bushels per
acre is 12 bushels less than the previous year. (Kansas
Agricultural Statistics)

The growth unit or growing-degree-day concept was
developed to measure the amount of heat available for
growth and maturation. To calculate the daily
accumulation, add the maximum and minimum
temperatures for each day, divide by 2, and subtract a
base temperature of 50. Any temperature below 50°F
was considered to be 50, and any temperature over 86°F
was considered 86.
Explanatory information is given preceding data
summaries for each test. Tables 2 through 24 contain
results from the individual performance tests. Hybrids
are listed in order of increasing days to half silk and
increasing grain moisture for the current year, so hybrids
of similar maturity are shown together.
Many
companies submit seed treated with systemic insecticides
(Cruiser, Maxim, Poncho) that can affect yield in some
situations. A column listing insecticide seed treatments
for each hybrid is included to help interpret yield results.

temperature relative to normal are readily observed in
the graphs. A table with monthly totals and averages for
the growing season also is included.

2006 PERFORMANCE TESTS
Objectives and Procedures
Corn Performance Tests, conducted annually by the
Kansas Agricultural Experiment Station, provide
farmers, extension workers, and seed industry 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
the same group of hybrids is not grown uniformly at all
test locations.
Short-season corn performance tests target hybrids for
early-planted, short-season cropping systems. These
systems typically are used on soils with poor waterholding capacities, often subjecting the hybrids to severe
heat and drought stress in July and August. Earlymaturing hybrids can escape a good portion of the
typical stress if they are planted early.
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 2006
and the 30-year normal, in addition to the daily rainfall
amounts since last fall. Temperature graphs include
daily maximum and minimum temperatures compared
Figures 4 through 8 graphically summarize yield and
maturity information over the past few years for each
region.
In these figures, hybrid performance is
standardized by using the average of two check hybrids
present in every test. The number beside each bar shows
the number of tests in which a given hybrid was
compared with the check hybrids. In general, the greater
the number of comparisons, the greater confidence one
can place in the stated performance of that hybrid.
Symbols beside each bar indicate if a hybrid was
significantly greater (+) or lower (-) than the average of
the check hybrids. As with individual test results, small
differences should not be overemphasized. Relative
ranking and large differences are better indicators of
performance.
Most corn tests were planted at a rate 10% to 20% in
excess of the desired population and thinned only to
remove doubles. Planting to stand enables evaluation of
product performance for the entire growing season.
Four plots (replications) of each hybrid were grown at
each location in a randomized complete-block design.
Each harvested plot consisted of two rows trimmed to a
specific length, ranging from 20 to 30 feet at the
different locations. Four-row plots were used at some
locations where drought stress is common. Tests were
harvested with specialized plot 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%. Yields also are presented as percentage of test
average to speed recognition of highest-yielding hybrids.
Hybrids yielding more than 100% of the test average
year after year merit consideration. Adaptation to
individual farms for appropriate maturity, stalk strength,
and other factors also must be considered.
The percentage of lodged stalks is reported when
appropriate. Plants broken over below the ear and
dropped ears were considered lodged, although most
were harvestable with modern machinery. Severely
lodged stalks or dropped ears that could not be picked up
by normal harvest procedures were 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 at most locations,
dropped ears constitute a very small portion of lodging
and do not significantly affect yields.
Relative maturity is measured in terms of both number
of days from planting to silking and grain moisture at
harvest. Entries are listed in order of increasing maturity
based on days to silking and harvest moisture in the
current year to facilitate comparison of hybrids of like
maturity. Maturity can be critical when considering a
corn hybrid for a specific cropping system.
Small differences in yield or other characteristics should
not be overemphasized. Least significant differences
(LSDs) 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. Yield values in the top LSD group in each test are
highlighted in bold. The coefficient of variability (CV)
can be used in combination with the LSD to estimate the
degree of confidence one can have in published data
from replicated tests.

Excerpts from the
University Research Policy Agreement with Cooperating Seed Companies*
Permission is hereby given to Kansas State University to test varieties and/or hybrids designated on the attached
entry forms in the manner indicated in the test announcements. I certify that seed submitted for testing is a true
sample of the seed being offered for sale.
I understand that all results from Kansas Crop Performance Tests belong to the University and the public and shall
be controlled by the University so as to produce the greatest benefit to the public. Performance data may be used
in the following ways: 1) Tables may be reproduced in their entirety provided the source is referenced and data are
not manipulated or reinterpreted; 2) Advertising statements by an individual company about the performance of
its entries may be made as long as they are accurate statements about the data as published, with no reference to
other companies’ names or cultivars. In both cases, the following must be included with the reprint or ad citing the
appropriate publication number and title: “See the official Kansas State University Agricultural Experiment Station
and Cooperative Extension Service Report of Progress 968 ‘2006 Kansas Performance Tests with Corn Hybrids,’ or
the Kansas Crop Performance Test Web site, http://kscroptests.agron.ksu.edu, for details. Endorsement or recommendation by Kansas State University is not implied.”
