INTRODUCTION
To properly evaluate a soybean variety it should 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 cli-
matic conditions that occur throughout the State. The most common
limiting factor in soybean production is inadequate moisture during
pod development and filling. It is important that varieties from more
than one maturity group be evaluated. 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.
EXPERIMENTAL PROCEDURES
A randomized block design in 4 replications was used at each of
8 locations. One to three planting dates were used at each location
with the first planting at the optimal time for maximum yield. All
locations were on units of the Auburn University Agricultural Experi-
ment Station. Plots were 4 rows wide and 20 feet long with 16 ft. of
2 center rows harvested for yield determinations. All plots were
planted with conventional planters with a cone hopper to distribute
seed. Row width varied from 36 inches to 42 inches depending on
location.
SEASONAL CONDITIONS
Early in the 1973 season moisture was good and even in excess in
some locations. Adequate stands were obtained at all plantings. Mois-
ture was good during the early growth periods at all locations for the
early planting dates except at the Wiregrass Substation. Severe drought
conditions existed in 1973 during pod filling of mid to late season
varieties in the central part of the State. Good yields were obtained
for full season varieties in southern Alabama.
Rainfall for the period of August 15 through September 30 was
quite variable for the year 1971, 1972, and 1973 at each location
(Table 1). This is the period of pod development and fill for mid
to full season varieties.
Heavy rains caused delay in harvesting of some tests. Part of
the 1973 Brewton Field variety x date of planting test was not har-
vested due to late November and December rains.

DATA RECORDED
Yield of soybeans was determined by hand cutting the 2 center rows of
each plot and threshing with a plot thresher. 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 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 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 18% shattering.
5 - over 20% shattering.
Plant hei~gh was determined as the average length of plants from the
ground to the top extremity at time of maturity.
Height of first po
d 
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 gram/per 100 seeds.
Seed quality was based on a rating from 1 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 damage, and brightness. Much of the poor quality reported
* was due to late harvesting and to excessive rain.
upl stain ratings were given to seed samples on a scale 
of I to 5
as follows:
1 - no purple staining. 4- 9 to 19% staining
2 - I to 3% purple staining. 5 - over 20% staining
3 - 4 to 8% purple staining

were varieties released prior
to 1973 and a number of unreleased strains in the late stages 
of develop-
ment from the USDA Regional Testing Program. 
These strains were all
yielding above standard varieties in their maturity 
group and all have
good nematode resistance.
