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 photoperiodic, the
blooming period, period of pod development 
and fill, and maturity date of
a particular variety do not vary 
greatly from year to year. 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 essen-
tial 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 best suited 
to meet individual require-
ments.
EXPERIMENTAL PROCEDURES
Tests in.1978 were conducted at outlying units 
of the Alabama Agri-
cultural Experiment Station of Auburn University 
and two locations on cyst
infested fields on Henninger-Brothers Farm, 
Stephenson, Alabama, and Engel
Farm, Summerdale, Alabama.. A randomized block design 
with 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 K.E.M. 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 759 F. All plot areas 
were fertilized according to soil
test.
The entries in these tests included 
varieties released prior to 1978,
a number of unreleased strains in the late 
stages of development from the
USDA Regional Testing Program, and some 
commercial lines. Sources of seed
are listed on pages 6 and 7.
DISCUSSION OF DATA
Since results of field plot research are influenced by inherent 
soil
differences and soil moisture availability, 
it is not possible to deter-
mine exactly the yield potential of a variety 
at a given location. Varie-
tal performance may also vary from year to year 
because of variation in
rainfall, temperature, diseases, and nematodes. Therefore, 
long term yield
averages are more reliable in evaluating 
varietal performance.
Differences in yield for 1978 have 
been computed using Duncan's New
Multiple Range Test at the 5% level 
of probability. Yields followed 
by
the same letter are not considered 
to be significantly different. Co-
efficients of variation (CV,) 
are footnoted in the tables. This 
value
reflects the relative precision 
of the experiment; a small C.V, 
indicates
more precision in estimating the 
relative performance of varieties.
SEASONAL CONDITIONS
Early season moisture was quite variable during the growing season
in 1978. Northern Alabama had sufficient moisture early for good stands
and early growth, but midsummer drought was quite severe. Late June and
early July were dry at both Crossville and Winfield, whereas Belle Mina
had adequate moisture during this period. These conditions resulted in
tall plants with considerable lodging at Belle Mina, whereas at the drier
locations plant growth was limited and lodging was not a problem. All
northern Alabama locations were without rain from mid August almost through
September. Only light showers occurred from September 10 through 15 with
1.2 and 1.8 inches total for Winfield and Belle Mina, respectively. How-
ever, Crossville had 2.43 inches during this period, which probably accounts
for the difference in yields of the three locations.
Rainfall in central Alabama was deficient in late June and early July
at Prattville and Camden; however, Marion Junction had adequate moisture
throughout the vegetative period. Prattville and Camden were severely
drought stressed in late August and September during the pod fill stage
of full season varieties. The tests at Marion Junction had a similar
rainfall pattern but did not suffer as much at the early planting date.
This was probably due to the greater reserve of moisture held in the
heavy clay soil.
Rainfall in southern Alabama during early plant growth was about 
normal
for June at Monroeville and Headland, but was above normal at Brewton
and Fairhope. June and July rainfall for Brewton and Fairhope was 18.9
and 36.0 inches, respectively. Rainfall in pod fill stage (late August
and September) was limited at Brewton, Monroeville, and Headland. However,
Fairhope had good August moisture but only .25 inches from August 29 until
September 23. All Southern locations had good rains in latter part of
September which may explain in part the good performance of the full season
varieties at these locations.
Highest yield for two consecutive year's eere in southern Alabama at
Fairhope, where average yields of 43.7 bu/A were recorded for 30 cultivars.
In central Alabama on the heavy clay soils of the Black Belt Substation,
average yields were 33.4 bu/A across first two planting dates and 63 culti-
vars. The early maturity varieties (Group V) were the best yielding vari-
eties at the early planting dates in northern Alabama and Prattville in
tentral Alabama. However, the full season and late varieties were the high-
est yielding varieties in late planting dates in northern, central, and
southern Alabama, with the exception of Prattville Field.
The full- to late-season varieties have tended to yield the best in
central and southern Alabama locations for the past 4 to 5 years. At Pratt-
ville Field, however, the early varieties of maturity Groups V and VI have
out yielded the full- and late-season varieties at the early May planting
date.
Lodging was a problem only at Belle Mina where excessive plant height
was obtained. Seed quality and purple stain were not a problem due to the
dry weather during early pod development and very dry conditions at harvest
time.

DATA RECORDED
The yield of a crop is the primary factor of production when profits
are to be maximized. Other characteristics which are important 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. 1ot4y7eld' were
adjusted 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. Har-
vest date was approximately 7-10 days later than maturity date.

15 through
Loding was based on a scale o1 1 to 5 according to the following
criteria, see page 5 for illustrations:
I - almost all plants'erect .
2 either all plants leaning seligtly (less than 450) -or a few plants
3 either all plants leaning moderately (approximately 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.
Sterin ratings were based on shattering of the border rows 14 days
after maturity. The visual estimiates were rated on a scale of,1 to 5 as
follows:
I - ro shattering
2 1 to 3% shattering
3 4 to 8% shattering
4 - 9 to 19% shattering
5 - 20 or more shattering
Pl~t height was determined as the average length of rlants from the
ground to the top extremity at time of maturity.
Ahht: 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 given.planting date and location. Seed size is reported
as grams per 100 seeds.
Sed l ty was based on a rating from 1 to 5 according 
to the follow-
ing scale: (1) very good, (2) good,. (3) fair, (4) poor, 
and (5) very poor.
The factors considered were developmtont of seed, 
wrinkling duie to late hair-
vesting and to exce'ssive rain.

Northern Alabama
The tests in northern Alabama were located on Decatur clay loam
at Belle Mina, Hartsells fine sandy loam at Crossville, and Savannah
fine sandy loam at Winfield. Soybeans of Maturity Group VI are full-
season varieties for this area. Varieties of Group VII maturity tend
to be taller and later maturing in northern Alabama than at more sou-
thern locations. Thus, lodging may be :expected for Group VII varieties
in northern Alabama; however, lodging was not a problem in 1978 at Cross-
ville or Winfield. Lodging has been severe four 2 and 3 of the past
5 years at both Crossville and Belle Mina, respectively, and the taller
varieties have not yielded well. It has been the shorter varieties of
Group V maturity that have been the best-yielding varieties in early
plantings at Crossville and Belle Mina.
Essex has been the highest yielding variety for the past 5 years
at Crossville and Belle Mina with 36 and 41 bu/A, respectively, out-
yielding the second variety Tracy at Crossville and Forrest at Belle
Mina by 3 and 6 bu/A, respectively.
The best Maturity Group.lVI variety was Tracy in the early plantings
at Crossville and Belle Mina. At Winfield McNair 600, Lee 74, and Davis
yielded best for mid-May plantings.
New early lines that have performed well in northern. Alabama for the
past 2 to 4 years are Coker 156, Lancer, and Centennial. Coker 156 was
the highest or second highest yielding variety at five of the six 6xperi-
meios in northern Alabama for the 4-year average.

Central Alabama
The tests in central Alabama were located on Houston clay at Marion
Junction, Lucedale sandy loam at Prattville, and Forkland sandy loam at
Camden. Soybeans of Maturity Group VII are full season varieties in
this area. Varieties of maturity Groups V and VI are very early and
early, respectively. Maturity Group V varieties were approximately 5
inches shorter in central than northern Alabama locations in 1978.
Coker 136 and Forrest are the tallest Group V varieties planted in
the central tests. Their yields are not as high as the full season vari-
eties, but they could be used for early-harvest varieties as they mature
between September 20 and 30. At Prattville, Essex has produced slightly
better yields than either Coker 136 or Forrest, but its leaf drop tends
to be erratic in central and southern locations.
When planted mid-May at central Alabama locations, the maximum
yielding varieties for the past 4 to 5 years are: Group V varieties Essex,
Forrest, and Coker 136; Group VI varieties Coker 156, Davis, and Lee 74
at Prattville and Coker 156, FFR 666, and Tracy at Marion Junction. Davis
and Coker 156 performed better than other Group VI varieties at later
plantings at Marion Junction; Group VII varieties Bragg, and Ransom, were
superior at the late May and early June plantings; Group VIII varieties
Coker 338, Hutton and Cobb performed well at later plantings at Marion
Junction and Prattville.
New lines that performed well in 1978 at Marion Junction were 
Coker 488,
Coker 237, McNair 500, F71-1180, and NK Blend 100 for early plantings; and
Agripro 70, F71-1180, McNair 3129, Terra Vig 708 when planted at later
dates.

Southern Alabama
The tests in southern Alabama were on Benndale sandy loam at
Brewton, Malbis fine sandy loam at Fairhope, Lucedale sandy loam at
Monroeville, and Dothan sandy loam at Headland. Soybean of Maturity
Group VIII are full season varieties in the southern Alabama locations.
For a full season variety to yield well it must have good rainfall during
pod fill period (usually during September and early October). As can be
seen by Table 1, there has been excellent rainfall at all southern 
loca-
tions for 4 of the past 5 years at Brewton and Headland, 2 of the 
past
3 years at Monroeville, and for each of the past 5 years at Fairhope.
Because of excellent rainfall during pod fill the leading 
4 or 5 vari-
eties at each location are Maturity Group VII or VIII varieties.
Hutton, Coker 338, and Cobb have been consistent high 
yielders
at both Brewton and Fairhope.
Ransom and Bragg were frequently among 
the five or six top yield-
ing varieties in the southern locations for the past 5 years.
McNair 600, Davis, and Tracy have been the best 
yielding Group VI
varieties in southern locations.
Lines that have performed well 
for the past 3 years were Coker 156
at Fairhope, Brewton and Monroeville. For the past 2 years 
Ga Soy 17,
McNair 3183, Coker 237, and Agripro 70 were 
high yielding lines at
Brewton (early planting), Fairhope, and Monroeville.
New lines that performed well in southern Alabama in 1978 were
Dowling, F71-1180, F70-2060, FFR 668, and FFR 6143. These lines were
among the top three yielding entries in one or more of the four south-
ern locations with Dowling yielding 41 bu/A at Brewton in late planting.

Soybean Yields on Cyst Nematode Infested Fields
The soybean cyst nematode, Heterodera glycines, is a small 
micro-
scopic round worm which attacks the root systems 
of soybeans, snapbeans,
lespedeza, common vetch, and lupine.
In July of 1972 the Alabama State Department 
of Agriculture and Indis-
tries indicated that the soybean cyst nematodes had 
been found in a soy-
bean field in Escambia County. By October, 
1977 Dr. F. A. Gray of the
Alabama Cooperative Extension Service had indicated 
the soybean cyst nema-
tode had been found in soybean fields in 23 counties 
in Alabama.
In 1978 three field tests using from 8 to 12 soybean 
varieties were
placed on two fields on which the soybean cyst nematodes 
had been found.
Two tests were planted June 15, 1978 on the Henninger 
Brothers farm near
Stephenson in Jackson county and one test 
was planted June 16, 1978 on the
Engle Farm near Summerdale in Baldwin County. 
The tests contain 4 and 6
replications of each variety at each location 
respectively, and plots were
four. rows with 36-inch spacing wide 
and 23 feet long. The varieties used
are listed in tables 59 and 60. The 
three varieties that have resistance
to the cyst nematodes are Centennial 
(Group VI maturity) and Bedford 
and
Forrest (Group V maturity). The 
yields from the Jackson county 
location
shown in Table 59 were low due to an 
extended drought during late August
and early September. However, the very 
low yields in the Baldwin county
field, Table 60, were due to a severe problem 
of root-knot nematode Mel-
oidogyne arenaria. The variety Centennial 
is not resistant to this nema-
tode. Bedford and Forrest have a fair amount of resistance 
to this root-
knot nematode but are not well adapted to southern 
Alabama.

Soybean Protein and Oil
Soybean protein and oil contents were determined on samples
taken from the 1977 variety by planting date studies in northern,
central, and southern Alabama. These are shown in tables 61 through
65. Protein and oil content of soybeans grown at Crossville, Ala-
bama were 43 and 22%, respectively, at the early May planting date
and decreased to 41 and 20%, respectively, by late June date. With
the exception of the early planting date at Crossville and the
three planting dates on the Marion Junction all locations and plant-
ing dates had similar protein and oil content. The protein contents
of varieties grown on the Black Belt soil were similar to those 
at
the early planting at the Sand Mountain Substation, which average
43.4 to 44.4%. However, the oil content at the Marion Junction
varied from 18.6 to 19.8%, which was considerably less than the 22%
average for the early planting in northern Alabama.
