PERFORMANCE OF GRAIN SORGHUM HYBRIDS IN AIABAMA, 1990
D. L. Thurlow and W. C. Johnson

INTRODUCrION
Grain sorghum performance tests are conducted annually throughout Alabama
by the Alabama Agricultural Experiment Station. These tests give a comparison
of hybrid performance under the conditions at a particular location. The
locations used represent major soil and climatic areas of the State. The
performance of hybrids varies with location. Therefore, this report should be
carefully studied before a hybrid is selected.
XPERIMENTAL PROCEEURES
Cultural practices were uniform for all hybrids within a given test. The
experimental design for all tests was a randomized complete block with four
replications. Test plots were two 36-inch rows, 20 or 30 feet in length. The
target plant population was 60,000 plants per acre, with a seeding rate 25
percent higher to ensure a good stand. Test cultural practices are listed in
table 1.
Grain yields were obtained by harvesting the whole test plot with a plot
combine, and adjusting harvested grain weight and moisture to a standard 14
percent moisture and 56 pounds per bushel.
Lodging is given as the percentage of plants broken or leaning at an angle
of more than 45 degrees. The seedheads of lodged plants were not included in
the yields reported.
Time (days) to mid-bloom is one measure of relative maturity. This is
taken as days from planting to the date when approximately one-half of the
heads in the plot are in bloom.

Bird damage was heavy 
and relatively uniform 
in 1988 at the following
locations: Sand 
Mountain Substation, 
Crossville; Prattville 
Experiment
Field, Prattville; 
and Gulf Coast Substation, 
Fairhope. Damage in 
1989 was
heavy at Prattville 
Experiment Field, 
Prattville, and 
E.V. Smith Research
Center, Shorter. 
The test at Prattville 
Field was discarded 
because of the
bird problem in 
1989, but it had 
only moderate damage 
in 1990. There was
considerable damage 
at the Tennessee Valley 
Substation, Belle 
Mina, on a few
of the early varieties 
in 1989 and the test 
was discarded in 
1990 because of
the bird problem. 
Damage was light 
to none at the following 
locations in 1989
and 1990: Upper Coastal 
Plain Substation, 
Winfield; Monroeville 
Experiment
Field, Monroeville; and 
Wiregrass Substation, 
Headland. Bird damage 
can be a
problem in small fields. 
In selecting a hybrid, 
consideration should 
be given
to bird populations; 
if damage is anticipated, 
bird-resistant hybrids 
should
be used. Bird-resistant 
grain sorghum hybrids 
are sometimes difficult 
to
market and may have 
lower feed value than 
the non-bird-resistant 
hybrids.
VARIETIY COMPARISONS
The performance of hybrids 
varies among years 
and locations. Small 
yield
differences among 
hybrids may be the 
result of slight environmental 
or
cultural differences 
rather than differences 
in yield potential 
among hybrids.
To aid in determining 
real differences, a 
statistical analysis 
of variance was
performed on the 
data from each location. 
The L.S.D. (least significant
difference) at the 
5 percent level is 
reported to help 
determine real
differences between 
hybrid yields for each 
location. If the yield 
difference
is greater than the L.SOD. 
value between two hybrids 
at a given
location, the two hybrids 
are considered to 
be significantly different 
in
yield. The C.V. (coefficient 
of variation) is a measure 
of test variability.
-6-
An increase in its value indicates 
a decrease in the precision of 
the test
data.
The list of acceptable hybrids 
is based on 3-year-average grain 
yield and
lodging data. The list is divided 
into three regions, north, 
central, and
south. Since all acceptable 
hybrids are not equal in performance, 
a review of
the data fran several years 
at the test location similar 
to your situation is
the most reliable method for selecting 
a hybrid best suited for your farming
needs.
Anthracnose has become a 
major factor in grain 
sorghum production in
Alabama, and there were sporadic 
outbreaks of this disease during 
the 1987
growing season, but 
none were observed 
in 1988, 1989, 
or 1990. In years 
prior
to 1987, however, grain sorghum 
in many northeast and west-central 
Alabama
counties was devastated by anthracnose. 
Sane fields yielded 50 to 
75 percent
less grain than expected. Feed 
quality of much of the harvested 
grain from
diseased fields was also 
poor. Resistant grain sorghum 
hybrids have been the
best defense against anthracnose. 
Of available adapted grain sorghum 
hybrids,
Funk's G-1711 and Pioneer 
Brand 8333 have the best 
resistance to this disease.
Other hybrids with same anthracnose 
resistance are Dekalb DK-64 and 
Pioneer
Brand 8222. Good management 
plus use of disease-resistant 
grain sorghum
hybrids are necessary to reduce losses 
to anthracnose.
There was not a second or ratoon 
crop of sorghum in 1989 or 1990 
at any
location. Plant height 
of grain sorghum hybrids is 
reported as regional
averages (central, northern, 
southern) and a single location 
of Fairhope,
table 14.
The rainfall during June aid 
July in 1989 was good at 
all locations,
resulting in good yields except 
where bird damage was a problem, 
table 2.
However, rainfall in 1990 during 
these two months was quite variable.

ACENCWLED~MENTS
The performance trials 
were conducted in cooperation 
with the following
substation and experiment field 
superintendents and their 
staffs whose quality
work makes this
