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 mois-
ture during pod development and filling. It is important that varie-
ties from more than one maturity group be evaluated.since soybeans
are highly photoperiodic, the blooming period, period of pod develop-
ment and fill, and maturity date of a particular variety do not vary
greatly from year to year. Continued testing and evaluation of soy-
bean varieties and experimental strains by agricultural experiment
stations are essential if farmers, county Extension agents, seeds-
men, and other agricultural workers are to be provided with infor-
mation to help them select varieties best adapted to their loca-
lity 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 8 locations.
One to three planting dates were used at each location with the
first plantings made at the optimal 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 30 feet long with 15 feet of two center rows harvested for
yield determinations. Row width varied from 36 to 42 inches depending
on location. Seeding rates were 10 viable seed per foot of row based
on germination at 750F.
The entires included in these tests were varieties released
prior to 1974 and a number of unreleased strains in the late stages
of development from the USDA Regional Testing Program. These strains
were all yielding above standard varieties in their maturity group
and have good nematode resistance.
DISCUSSION OF DATA
Since field plot research is subject to inherent fertility
differences, and soil and soil moisture variations, it is not
possible to determine the exact yield 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, long
term studies are necessary in order to properly evaluate varietal
performance.
Differences in the yield for 1 year's data, which may be due to
chance, have been computed using Duncan's Multiple Range Test (5%)
level of probability. Yields followed by a common letter are not
considered to be different, however means not associated by a common
letter are considered to be different. Coefficients of variation
(C.V.) are footnoted in the table. This value reflects the rela-
tive precision of the experiment, a small C.V. indicating more
precision in estimating the relative performance of varieties.
SEASONAL CONDITIONS
Early season moisture was good at all locations and good stands
were obtained in all tests. Due to a lack of moisture in the southern
part of the State in late June and early July, plants were shorter
than normal and lodging was not a problem in these tests. Lodging
was, however, a problem in North Alabama at Belle Mina for the
second straight year. This may be why the early maturing and shorter
varieties produced higher yields at this location than the full season
and later maturing varieties.
Later maturing varieties, Maturity Group VI, VII, and VIII, were
also killed by frost, October 3, 1974, which occurred approximately
14 days before normal in North Alabama.
Late season moisture (Table 1) was good at all locations in the
southern part of the State and resulted in yields of 47 to 62 bu/A
for the better varieties planted at the optimum planting time.
Table 1 also shows rainfall data from each location for the period
August 15 through September 30 over the past 4 years.

DATA RECORDED
In order to select the proper variety many factors must be consi-
dered. The yield of a crop is the primary factor of production when
profits are to be maximized. Other characteristics which are impor-
tant are date of first bloom, plant height, 
height of 1st pod, maturity,
lodging, shattering and size of quality seed. Also soybean varieties
grown in this area are photoperiodic plants and therefore are effected
by planting date.
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 bushel (60
lb.) per acre.
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.
Lodging was based on a scale of 1 to 5 according to the following
criteria.
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 (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.
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 follows:
1 - no shattering
2 - 1 to 3% shattering
3 - 4 to 8% shattering
4 - 9 to 19% shattering
5 - over 20% shattering
Plant heg 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
following scal.: (1) very good, (2) good, (3) fair (4) poor, and
(5) very poor. The factors considered were development of seed
wrinkling to late harvesting and to excessive rain.
Purple stain ratings were given to seed samples on a scale of
I to 5 as follows-. .
1 no purple staining
2 1 to 3% purple staining
3 -4--8% purple staining
4 9 to 19% staining
5- over 20% staining
