2012 GRAIN SORGHUM CROP REVIEW
Statewide Growing Conditions
Diseases
The 2012 Kansas grain sorghum growing season was
extremely challenging for most of the state for the second
year in a row. Although grain sorghum is well suited for hot,
arid growing conditions, the 2012 crop was stressed beyond
its limit of endurance in many regions of the state with
extended periods of high heat and very limited rainfall.
(Figure 1). Heat stress was a statewide problem that affected
pollination and grain-filling, either forcing the sorghum to
develop at an accelerated pace or causing the plants to stop
growth altogether. Many fields failed to make a crop. The
dryland grain sorghum performance tests at Beloit, Assaria,
Hutchinson, Hays, Tribune, and Colby were abandoned
because of acute drought conditions. The irrigated test at
Hutchinson was lost to bird feeding.
As was the case in 2011, disease pressure in 2012 was very
low. Early planted sorghum that received some rain before
the drought suffered significantly from Fusarium
seedling blight. Sooty stripe, the most common foliar
disease of sorghum in Kansas, was very difficult to find
except in a few irrigated fields.
The quality of the grain sorghum crop was directly affected
by the adverse conditions; less than 10% of the crop was
rated in good or excellent condition by the end of the
growing season (Figure 2).

The most significant disease present in 2012 was stalk rot.
Both Fusarium stalk rot and charcoal rot were present at
above normal levels, resulting in occasional lodging. Even
where lodging did not occur, the heads on stalk rot-infected
plants generally are smaller and result in reduced yields.
No other diseases were a significant issue in 2012. Other
diseases observed included Fusarium neck rot, rough spot,
head smut, crazy top downy mildew, and bacterial streak.
(Doug Jardine, Kansas State University Department of Plant
Pathology)
Insects
Seedling plants struggled throughout much of the state due
to the hot, dry weather. Because the plants were already
subjected to enormous stress, chinch bug feeding heavily
impacted many fields. Even those fields with what would
usually be considered non-economic infestation levels were
negatively impacted because of the stress already created by
the weather, and either eventually died or seemed to be in
a state of suspended growth, neither dying nor
producing any grain.
Many fields that did produce grain did have sorghum
headworm infestations, but those were not as common as in
previous years. (Jeff Whitworth, Kansas State University
Department of Entomology)

The Kansas Agricultural Statistics Service predicted a 82.5
million-bushel crop in the October 11 Crops Report, down
24% from last year (Figure 3). The number of acres
harvested was down 100,000 acres from last year, at 2.1
million. The average yield estimate of 40 bushels per acre is
15 bushels lower than last year’s yield. Kansas leads the
nation in sorghum acreage planted and harvested but is
second behind Texas in production. (Kansas Agricultural
Statistics Service, Topeka)

Total bushels
Figures 4 through 6 graphically summarize yield and
maturity information over the past 3 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.
Symbols beside each bar indicate if performance of a hybrid
was significantly greater (+) or lower (-) than the average
performance 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 tests were planted at a rate 25 to 30% greater than the
desired population and thinned only to remove doubles.
Planting to stand enables evaluation of product performance
for the entire growing season.

2012 PERFORMANCE TESTS
Objectives and Procedures
Three or four plots (replications) of each hybrid were grown
in a randomized complete block design at each location.
Each harvested plot consisted of two rows trimmed to a
specific length ranging from 20 to 30 feet at the different
locations.
Grain Sorghum 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 grain
sorghum hybrids marketed in the state. 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 at all test locations.
Grain yields are reported as bushels per acre of shelled grain
(56 lb/bu) adjusted to a moisture content of 12.5%. Yields
also are presented as a 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.
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 2012 and the 30-year normal in addition
to 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. A table with monthly totals and averages for the
growing season also is included.
The percentage of lodged stalks is reported when
appropriate. Both broken stalks and stalks leaning more
than 45 degrees from vertical were considered lodged,
although most were harvestable with modern machinery.
Severely lodged stalks or dropped heads 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 lodge simply because they must wait well past their
optimum harvest date.
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 growing
degree day accumulation, add the maximum temperature and
the minimum temperature for each day, divide by 2, and
subtract a base temperature of 35°F. Any temperature below
35°F was considered to be 35°F.
Explanatory information precedes data summaries for each
test. Tables 2 through 12 contain results from the individual
performance tests. Hybrids are listed in order of increasing
days to half bloom when that information is available, so
hybrids of similar maturity appear together.
Relative maturity is measured both in terms of number of
days from planting to half bloom and grain moisture at
harvest. Maturity can be critical when considering a
sorghum hybrid for a specific cropping system.
Small differences in yield or other characteristics should not
be overemphasized. Least significant differences (LSD) 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.
-2-
The coefficient of variability (CV) can be used to estimate
the degree of confidence one can have in published data
from replicated tests. In this testing program, a CV of less
than 10% generally indicates reliable, uniform data, whereas
a CV of 10 to 15% is not uncommon and usually indicates
that data are acceptable for the rough performance
comparisons desired from these tests. Tests with a CV
greater than 15% still may be useful, especially in situations
with low yields.

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 1077, ‘2012 Kansas Performance Tests with Grain Sorghum Hybrids,’
or the Kansas Crop Performance Test website, www.agronomy.ksu.edu/kscpt, for details. Endorsement or recommendation by Kansas
