INTRODUCTION
To properly evaluate a soybean variety it is necessary that it be
grown at a number of locations, at various planting dates, and over a
period of years. This will subject the variety to differences in soil
and climatic conditions that occur throughout the State. The most common
limiting factor in soybean production is inadequate moisture during pod
development and filling. Since soybeans are highly photo periodic, the
blooming period, period of pod development and fill, and maturity date of
a particular variety do not vary greatly from year to year for a given
planting date. Thus, it is important that varieties from more than one
maturity group be evaluated at each location. Continued testing and
evaluation of soybean varieties and experimental strains by agricultural
experiment stations are essential if farmers, county extension agents,
seedsmen, and other agricultural workers are to be provided with
information to help them select varieties best adapted to their locality
and management needs.
EXPERIMENTAL PROCEDURES
Tests in southern Alabama were conducted at four substations or
experiment fields of the Alabama Agricultural Experiment Station of
Auburn University and one location on a nematode infested field (Gottler
Farm, Elberta, Alabama). A randomized block design with 3 or 4
replications was used at each location with the first planting made at
the optimum time for maximum yield. Plots were planted with regular
commercial soybean planters equipped with special seed hoppers adapted
for small plots. Plots were four rows wide and 23 feet long with 16 feet
of the two inner rows harvested for yield determinations. Harvest was
done with a small plot combine at all locations. Row width varied from
36 to 40 inches depending on location. Seeding rates were 10 viable seed
per foot of row based on germination at 75
0
F. All plot areas were
fertilized according to soil test.
The entries in these tests included varieties released prior to
1980, a number of unreleased lines in the late stages of development from
the USDA Regional Testing Program, and some commercial lines. Sources of
seed are listed on pages 11 through 13. Varietal description and disease
resistance factors are shown in table 2.
The tests in southern Alabama were on Benndale sandy loam near
Brewton, Malbis fine sandy loam near Fairhope, Lucedale sandy loam near
Monroeville, and Dothan sandy loam near Headland. .Soybeans of Maturity
Group VIII are full season varieties in the southern Alabama locations.
Soybean varieties in Maturity Group VII are also considered well adapted
for southern Alabama. Varieties from maturity groups V and VI are
considered very early and early maturing, respectively, and usually do
not yield as well as the later maturing cultivars.
The test near Headland had supplemental irrigation applied to half
of the six-replication test. This irrigation was applied with a
traveling gun at a rate of 1.5 inches on each of the following dates:
July 10 and 15 and September 11 and 25.
DISCUSSION OF DATA
Since results of field plot research 
are influenced by inherent soil
differences and soil moisture 
availability, it is not 
possible to
determine exactly the yield potential 
of a variety at a given location.
Varietal performance may also vary 
from year to year because of variation
in rainfall, temperature, disease, and nematodes. 
Therefore, long term
yield averages are more reliable 
in evaluating varietal performance.
Differences in yield for. 1981 have been 
computed using Duncan's
Multiple Range Test at the 5% level 
of probability. Yields followed by
the same letter are not considered 
to be significantly different.
Coefficients of variation (C.V.) 
are footnoted in the tables.
Seasonal Conditions
Early season moisture was good 
in southern Alabama in 1981 and
adequate stands were obtained at 
all plantings. There was some moisture
stress in June in southern Alabama, 
table 1. Adequate plant height 
was
obtained by all cultivars except the very 
early Group IV entries in the
Wiregrass area. Rainfall amount 
and distribution was adequate at all
locations during July and Au.gust except 
a slight stress period in July at
Headland where 3 inches of water 
was supplied to the irrigated area. 
All
locations experienced a drought 
from September 8 through October 24
during the period that most entries 
were harvested. During September 
3
more inches of water was applied to the 
irrigated test at Headland.
Brewton (tables 3-11)
The highest yielding soybean cultivars 
have been those of Group VII
and Group VIII over the past 4 to 5 years with average yields of
approximately 42 bu./a. for 10 entries planted 
May 30 at Brewton Field.
The lack of rainfall after September 16 
through October 9 in 1981
resulted in the yields of Group VIII entries 
being lower yielding than
some of the earlier entries in Group VI. More 
than 50 bu./a. were
obtained from 12 cultivars at this location in 1981. Group 
VIII
cultivars were the highest yielding 
in 1981 at Brewton when planted June
25, but top yields were approximately 
10 bu./a. less than at the May 25
planting date.
Monroeville (tables 17-21)
The soybean yield pattern at MonroevillTe was similar to that at
Brewton in that the highest average yields for maturity groups were 
those
of the Group VII entries, however, the yield was generally lower 
than
Brewton. The top seven cultivars yielded more than 40 bu./a. 
with
-2-
Agripro 70 yielding 47.9 bu./a. The lack of rainfall at Monroeville
after September 16 limited the yield of Maturity Group VIII entries more
than the earlier entries.
Five-year average yields indicate that the Group VII entries Bragg
and Ransom and Group VIII Entries Coker 338, Cobb, and Hutton all yield
approximately 39 bu./a. but the Group VI entries Centennial, Coker 156,
Davis, Tracy, and Lee 74 over the same period averaged 3 bu./a. less.
Fairhope (tables 12-16)
Three of the four highest soybean yields at Fairhope in 1981 were
from very early Group V cultivars Deltapine 105, Bedford, and Forrest.
These entries had excellent soil moisture up to 10 days before maturity.
However, there was little soil moisture or rainfall after September 7
through October 24 (1.1 inches of rainfall in 48 days). Therefore, the
average yields at Fairhope in 1981 were 38.1, 34.5, 36.4, and 30.1 bu./a.
for the Group V, Group VI, Group VII, and Group VIII entries,
respectively. When the 5-year average at Fairhope is used which included
the 1979 hurricane damaged soybeans the average yields of 34.5, 37.5,
39.1, and 35.6 bu./a. were obtained by maturity groups V, VI, VII, and
VIII, respectively.
Headland (tables 22-26)
The moisture at Headland was much less for June and early July than
the other southern locations and 3 inches of water was applied in two
irrigations to half of the soybean variety test. From July 20 to
September 8, 10.4 inches of rainfall fell. Water was again applied on
September 10 followed by 2.2 inches of rainfall on September 14 to 16 and
a final irrigation of 1.5 inches of water on September 25.
Plant height was increased only slightly (1.4 inches) by the July
irrigation for the Group VIII maturity group and no change in plant
height was measured for the Group VI or Group 
VII cultivars. There were
ten entries that yielded approximately 50 bu./a. or more without
supplemental irrigation at Headland in 1981 and eight of these cultivars
were Group VII entries. The increased response to irrigation by the
Group VII cultivars was 0.5 bu./a. from 49.4 bu./a. without irrigation.
There were sixteen entries that produced 50 bu./a. or more with
supplemental irrigation in 1981 and 8 of these entries were Group VIII
cultivars. The Group VIII entries had an average yield of 52.1 bu./a.
with irrigation and the average response to irrigation was 4.5 bu./a. in
1981. The Group VI entries responded similarly to the Group VII Entries
as there was only an increase of 0.6 bu./a. due to irrigation over the
44.3 bu./a. average for non-irrigated cultivars. The greatest increase
in yield due to irrigation was 7.9 bu./a. which was from the Group V
entries, however, they had the lowest average non-irrigated yield of 30.2
bu./a. as a group. The 2-year average irrigated yield at Headland shows
that the seven Group VIII cultivars tested are averaging 50 bu./a. These
were 3, 5, and 15 bu./a. greater than the average yield of the Group VII,
Group VI, and Group V cultivars, respectively, that were.grown during the
2 years 1980 and 1981.
-3-
Effect of Planting Date on Yield
SThe highest yielding cultivars at the Brewton field over the past
5 years 1977 through 1981 were 
the Group VIII entries with 
41.8 bu./a.
when planted May 30. This group of cultivars also had the lowest
reduction in yield of approximately 14% when planting was delayed by 1
month to June 26. This compares to a 21% and 26% reduction in yield from
38.5 and 41.7 bu./a. for cultivars from Maturity Groups VI and VII,
respectively, when planting was delayed from May 30 to June 26 during the
5-year period.
Seed Quality and Purple Stain (table 30)
Seed quality .and purple stain rating are shown in table 30. Poor
seed quality was only found in 1981 on the very early entries in south
Alabama. The extended dry period in late September and October resulted
in most soybean seed being of good quality.
Seed Size (table 31)
Seed size (g/1:00 seed) is usually affected by two factors genetic
and soil moisture availability during the late stages of pod fill, table
31. The seed size was much larger at Brewton than Monroeville or
Fairhope. This was also reflected in the yield as the soil moisture was
greater at Brewton late in the season than at either Monroeville or
Fa.irhope.
USDA Regional Tests (tables 27-29)
Regional uniform tests were conducted at Fairhope in maturity groups
VI, VII, and VIII. These tests are shown in tables 27, 28, and 29.
Centennial .and Tracy M are the standard varieties in Uniform VI. Braxton
and Wright are the standard varieties in Uniform VII. Hutton and Cobb
are the standard varieties in Uniform VIII tests. In the Uniform VI test
there were, five entries (N75-2213, N77-114, R74-39K, 078-5502, and
077-6057) that gave better yields than the standard variety, Centennial.
There were not any new lines that yielded better than the. standard
entries in either..of the Group VII or VIII tests. The lower yields in
the Group VII and VIII tests were due to the severe drought with only 1.1
inches of rainfall at Fairhope from September 7 through October 24.
Soybean Yields on Nematode Infested Field (tables 32 and 33)
In 1981 two tests were conducted on the Gottler Farm near Elberta to
evaluate the effect of root-knot nematodes on growth and yield of 14
cultivars and 12 breeding lines of soybeans. The root-knot nematode
found in the field site was identified as a species of Meloidogy .:
Incognita.. Test one in table 32 was made up of breeding lines-fromDr.
Hinson,USDA Plant Breeder from Florida, and Dr. Hartwig, USDA Plant
Breeder from the Delta Branch Substation at Stoneville, Mississippi.
-4-
This test was replicated three times. The lines F77-1790 and F77-2000
yielded better than the two. standard varieties Braxton and Govan and
F77-1990, F77-1840, F77-1797 had a lower root-knot gall rating than the
standard varieties.
In the second test, table 33, the two early cultivars Forrest and
Bedford, Wright, Govan, and Coker line 80-846 were the highest yielding
in the four replication tests. The root-knotrating on the second test
was not as low as the lines in test one. The breeding lines in table 32
are also resistant to the cyst nematode Heterodera glycine, race 3.

DATA RECORDED
The yield of a crop is the primary factor of production when
profits are to be maximized. Other characteristics which are im-
portant are plant height, height of lowest pod, maturity, lodging,
and size and quality of seed.
Yield of soybeans was determined by harvesting the two center
rows of each plot with a small plot combine. Plot yields were ad-
justed to 13% moisture and converted to bushels (60 pounds) per
acre.
First bloom was taken as the date when there was one flower
at any node on 10% of the plants.
Maturity was rated as the date when the pods were dry and
most of the leaves had dropped. Under most conditions, the stems
were also dry. Harvest date was approximately 7-10 days later
than maturity date.
Lodging was based on a scale of I to 5 according to the fol-
lowing criteria, see page 8 for illustrations:
1 - almost all plants erect.
2 - either all plants leaning slightly (less than
450) or a few plants down.
3 - either all plants leaning moderately (approxi-
mately 450) or 25 to 50% of the plants down.
4 - either all plants leaning (more than 450) or
50 to 80% of the plants down.
5 - all plants down.
-6-
Shattering ratings were based on shattering of the border rows 14
days after maturity. The visual estimates were rated on a scale of I to
5 a-s follows:
1 - no shattering.
2 -.1 to 3% shattering.
3 - 4 to 8% shattering.
4 - 9 to 19% shattering.
5 - 20% or more shattering.
Plant height was determined as the average length.of plants from the
ground to the top extremity at time of maturity.
Height of first pod was determined as the average height of the
lowest pods from the ground at maturity.
Seed size for each variety was determined from a composite sample of
all replications at a gi.ven planting date and location. Seed size is
reported as g per 100 seeds. Small, medium, and large seed size will be
8-12, 13-16, and 17-20 g/100 seed, respectively, and will have
approximately 5,700 to 3.,800, 3,500 to 2,800, and 2,700 to 2,300 seeds
per pound, respectively.
Seed quality was based on a rating from I to 5 according to the
following sCale: (1) very good, (2) good, (3) fair, (4) poor, and
(5) very poor. The factors considered were development of seed,
wrinkling due to late harvesting, and to excess rain.
Purple stain ratings were given to seed samples on a scale of 1 to 5
as follows:
1 - no purple staining.
2 - 1 to 3% purple staining.
3 - 4 to 8% purple staining.
4 - 9 to 19% purple staining.
5 - 20% or more staining.

Lodging was based on a 
scale of I to 5 according
to the following criteria 
and illustrated by figures 
1
through 5 respectively.
1 - almost all plants erect.
2 - either all plants leaning 
slightly (less than 450)
or a few plants down.
3- either all plants 
leaning moderately 
(ap-
proximately 450) or 25 
to 50% of the plants
down.
4 - either all plants leaning 
considerably (more
than 450) or 50 to 80% 
of the plants down.
5 - all plants down.
