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
periodof years. This will subject the variety to differences in soil and
climatic conditions that occur throughout the State. The most common limit-
ing factor in soybean production is inadequate moisture during pod develop-
ment and filling. Thus, it is important that varieties from 
more than one
maturity group be evaluated at each location. 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. Continued testing and evaluation of soybean 
varieties and experimental
strains by agricultural experiment stations is essential 
if farmers, county
Extension agents, seedsmen, and other agricultural workers are to be pro-
vided with information to help them select varieties best adapted to their
locality and individual requirements.
EXPERIMENTAL PROCEDURES
All tests were conducted at outlying units of the Alabama 
Agricultural
Experiment Station of Auburn University. A randomized block design with 4
replications was used at each of 10 locations. Where possible several plant-
ing dates were used at each location with the first plantings made at the
optimum time for maximum yield. Plots were planted with regular commercial
soybean planters equipped with a special seed hopper adapted for small plots.
Plots were four rows wide and 23 feet long with 16 feet of the two center
rows harvested for yield determinations. 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 750 F. All plot areas were fertilized
according to soil test.
The entries in these tests included varieties released prior to 1977,
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. Varietal
performance may vary from year to year because of variation in rainfall,
temperature, diseases, and nematodes. Therefore, the longer term yield
averages are more reliable in evaluating varietal performance.
Differences in yield data for 1977 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 (C.V.) 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 1977.
Northern Alabama had sufficient moisture early for good stands and adequate
early growth, but midsummer drought was quite severe. There was a dry period
of 64 days in July and August at Belle Mina which resulted in pod drop and
consequently low yields. Similar dry conditions were evident at the other
locations in Northern Alabama but were not as drastic as at the Tennessee
Valley Substation. The heavy rains in September after the dry August re-
sulted in very poor quality beans from early harvested varieties.
Rainfall in central and southern Alabama was below normal in April,
May, and early June, which resulted in stand problems and very slow early
growth. Tests were abandoned at Lower Coastal Plain Substation and Wire-
grass Substation because of very poor stands. A dry period early in July
at the Black Belt Substation caused severe iron chlorosis on varieties
in all three planting dates as shown in table 34.
Highest yields were obtained from tests in southern Alabama at Brewton
and Monroeville Experiment Fields where 25 and 23 inches of rainfall re-
spectively was measured during the period of July, August, and September.
Yields varied from 33 to 62 and 37 to 58 for the two locations respectively.
The early Group V maturity varieties were the lowest yielding varieties and
the highest yielding varieties were full season varieties in Maturity Groups
VII and VIII.
The mid- to late-season varieties have tended to yield the best in
central and southern Alabama locations for the past 5 years as is evident in
the 5-year average tables. This was also true for the early plantings
in northern Alabama due to the early summer drought; however, early varieties
yielded well at later planting dates as is evident at the Sand Mountain
Substation.
Lodging was not a problem at any location or planting date in 1977 due
to early summer drought. Seed quality was very poor in northern Alabama for
all early maturing varieties when planted early.

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 first pod, maturity, lodging, and size and quality of seed.
Yield of soybeans was determined by cutting the two center rows of
each plot and threshing with a plot thresher (or small plot combine). Plot
yields 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. Harvest
date was approximately 7-10 days later than maturity date.
Lodging was based on a scale of 1 to 5 according to the following
criteria, see page 5 for illustrations:
1 - almost all plants erect.
2 - either all plants leaning slightly (less than 45
?
) or a few plants
down.
3 - either all plants leaning moderately (approximately 450) or 25 to
50% of the plants down.
4 - either all plants leaning considerably (more than 45
?
) or 50 to 80%
of the plants down.
5 - all plants down.
Shattering ratings were based on shattering of the border rows 14 days
after maturity. The visual estimates were rated on a scale of 1 to 5 as
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 given planting date and location. Seed size is reported
as grams per 100 seeds.
Seed quality 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 development of seed, wrinkling due to late har-
vesting and to excessive rain.
Purple stain ratings were given to seed samples on a scale of 1 to
5 as follows:
1 - no purple staining 4 - 9 to 19% staining
2 - 1 to 3% purple staining 5 - 20% or more staining
3 - 4 to 8% purple staining

Northern Alabama
The test locations in northern Alabama were 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 southern loca-
tions. Thus, lodging may be a problem for Group VII varieties in northern
Alabama; however, lodging was not a problem in 1977. Lodging has been
a problem for 3 of the past 5years at both Crossville and Belle Mina and
the taller varieties have not yielded well. It has been the shorter var-
ieties 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 35 and 46 bu/A, respectively, out-
yielding the second variety Tracy at Crossville and Forrest at Bell Mina.
The best Group VI maturity variety was Tracy in the early plantings
at Crossville. At Winfield McNair 600, Lee 74, Davis, and Tracy yielded
best for mid-May plantings.
New early lines that have looked good in northern Alabama for the
past 2 to 3 years are Coker 842, Coker 136, Lancer, and Centennial. Coker
842 was the highest or second highest yielding variety in four of the six
locations in northern Alabama.

Central Alabama
The test locations in Central Alabama were on Sumter clay at
Marion Junction, Lucedale sandy loam at Prattville, and Forkland sandy
loam at Camden. The Camden test was dropped due to very poor stand. Soy-
beans of Maturity Group VII are full season varieties in this area. Var-
ieties of maturity groups V and VI are very early and early, respectively.
Maturity Group V varieties were approximately 10 inches shorter in central
than northern Alabama locations in 1977.
Coker 136 and Forrest are the tallest Group V varieties planted in
the central tests. Their yields are not as good as the full season varieties,
but could be used for early harvest varieties as they mature bewteen Sep-
tmeber 20 and 30. Essex has produced slightly better yields at Prattville than
either Coker 136 or Forrest, but its leaf deop tends to be very erratic in
central and southern locations.
The maximum yielding varieties when planted mid-May at central Ala-
bama locations for the past 4 to 5 years are: Group V varieties Essex,
Forrest, and Coker 136; Group VI varieties Davis, FFR 666, McNari 600, Lee
74, and Tracy for mid-May plantings and Davis and Tracy at later plantings
at Marion Junction; Group VII varieties Bragg, and Ransom, particularly
at the late May and early June plantings; Group VIII varieties Coker 338,
Hutton, and Cobb performed well at later planting at Marion Junction and Pratt-
ville.
Lines that have looked good for 3 years were Coker 842 and Green Soy
74-64 at Marion Junction and Prattville. New lines that performed well in
1977 at both gentral Alabama locations were Ga. Soy 17 and D&PL 5.

Southern Alabama
The tests in southern Alabama were on a Benndale sandy loam at
Brewton, Malbis fine sandy loam at Fairhope, Lucedale sandy loam at Mon-
roeville, and Dothan sandy loam at Headland. Soybean of Maturity Group
VIII are full season varieties in the southern Alabama loaations. For a
full season variety to yield well it must have good rainfall during podfill
period (usually during September and early October). As can be seen by
table i, there has been excellent rainfall at all southern locations for
the past 5 years at Bewton, Fairhope, and Headland and the past 2 years
at Monroeville. Because of excellent rainfall during pod fill the lead-
ing three or four varieties at each location are Maturity Group VII or
VIII varieties.
Hutton has been the most consistent yielder at both Brewton and
Fairhope. Other Group VIII varieties that yield well are Coker 338
and Cobb.
Ransom and Bragg were frequently in the 'top five or six yielding
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 lcoations.
Lines that have performed well for the past 3 years were Coker 842
at Fairhope and Brewton and for the past 2 years McNair 3131 was a high
yielding line at Brewton early planting and Monroeville.
New lines that performed well in southern Alabama in 1977 were Coker
73-370, Ga. Soy 17, Agripro AP7O, and McNair 3183. These lines were in the
top three yielding varieties in one or more of the three southern locations
with Coker 73-370 yielding over 62 Bu/A at Brewton.
