Diseases
Several diseases had economic effects on the 2008
Kansas corn crop. Most notable was gray leaf spot
(GLS). This disease was prevalent over a wide area of
the state; the most significant levels were reported
from the Kansas River valley and south central
Kansas. In some fields planted to susceptible hybrids,
GLS lesions could be found on leaves above the ear at
silking.
2008 CORN CROP REVIEW
Statewide Growing Conditions
The 2008 growing season was delayed by widely
spread rains and wet soil conditions until later in the
spring (Figure 1). Frequent rains and cooler than
normal temperatures continued through June and July.
The end of July brought drier weather, causing some
stress to the rapidly developing corn. Rains and cool
weather returned in October, and many acres of corn
were subjected to freezing temperatures before
reaching maturity. Harvest was delayed into
November for some areas of Kansas. Condition of the
2008 corn crop was, for the most part, rated as good or
fair throughout the growing season (Figure 2).
Southern rust was also of economic significance in
2008. This disease, which blows in from the South
each year, arrived at least 2 weeks earlier than normal.
Fungicide applications were needed in late fields
planted to susceptible hybrids.

80%
Common rust was also present at levels far above
normal. Research on this disease, however, indicates
that fungicide control is rarely beneficial because of
its relatively small effect on yield.

Other diseases reported in 2008 included Physoderma
brown spot, wheat streak mosaic virus, anthracnose,
head smut, common smut, Diplodia ear rot and Goss’s
bacterial wilt. Though perhaps important in individual
fields, none of these diseases occurred on a
widespread basis. (Doug Jardine, Kansas State
University Department of Plant Pathology)

Problems from early season corn pests were scattered

the eastern half of the state.

Spider mite populations started to become apparent in
early July in western Kansas, but cooler weather
settled in and populations seemed to decline.
Figure 2. Condition of 2008 Kansas corn crop
(Crop Weather Reports, Kansas Agricultural Statistics
Service, Topeka)
Many reports of fall armyworm problems were
received from late planted corn, but overall, corn
insect pests were about average, or even a little less,
throughout the state. For the most part, corn producers
seem to be doing a good job of managing perennial
corn insect pests. (Jeff Whitworth, Kansas State
University Department of Entomology)
Harvest Statistics
The October 10 Crops Report predicted a 493.2
million-bushel crop, down 5% from last year. In 2008,
3.6 million acres were harvested for grain, down 3%
from 2007. The predicted average yield of 137 bushels
per acre is 3 bushels less than the previous year.

2008 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 finance the tests.
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. 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 in Table 16 is included to help interpret yield
results.
A table with monthly totals and averages for the
growing season is also included.
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.
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.
Grain yields are reported as bushels per acre of shelled
grain (56 lb/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.
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.
Explanatory information is given preceding data
summaries for each test. Tables 2 through 15 contain
results from the individual performance tests. Hybrids
are listed together by company name.
The percentage of lodged stalks is reported when
appropriate. 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 can 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.
Figures 3 through 9 graphically summarize yield and
maturity information over the past few years for each
region. Relative maturity is measured in terms of both
number of days from planting to silking and grain
moisture at harvest and can be critical when
considering a corn hybrid for a specific cropping
system. 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 whether a hybrid
was significantly greater (+) or less (-) than the
average of the check hybrids.
Small differences in yield should not be
overemphasized. Relative ranking and large
differences are better indicators of performance. Least
significant differences (LSD) are shown at the bottom
of each table. Unless two hybrids 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 displayed 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.
A summary of growing season weather data is given
for individual test discussions. Precipitation graphs
include cumulative lines for 2008 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.
General trends in precipitation and temperature
relative to normal are readily observed in the graphs.

Excerpts from the University Research Policy Agreement with Cooperating Seed Companies
Permission is hereby given to Kansas State University (KSU) 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 1000, ‘2008 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.”
