 . Kentucky Soybean Performance
_ Tests- 1974
By D. B. Egli, Charles Tutt and ]. M. Wood
The objective of the Kentucky Soybean Performance
Tests is to provide an estimate of the relative performance of
soybean varieties in Kentucky. This information may be used
by growers and seedsmen in selecting the variety that will give
  the highest total production for a specific situation. Experi-
· mental strains of soybeans provided by the U. S. Regional Soy-
bean Laboratory are also tested at several locations in Ken-
tucky.
. Soybean tests in 1974 were conducted at four locations
in the major soybean—producing areas of the state and at
Lexington. The testing locations, soil types, planting date and
row width are shown on the opposite page. Each variety was
planted in three plots (replications) at all locations, with
· individual plots being 3 rows wide and 20 feet long. The seeding
rate was approximately 8-10 viable seed per foot of row.
A 16-foot section from each of the center rows was
_ harvested for yield. Plants were cut by hand and threshed with a
. small nursery thresher. All branches and lodged plants were
harvested from each plot. The yield of the varieties is reported
as bushels per acre at 13% moisture.
Lodging
i Lodging was rated on a scale of 1 to 5; l = almost all
plants erect; 2 = all plants over slightly or a few down; 3 = all
3

 plants over moderately or 25% down; 4 = all plants over con- _
siderably or 50-80% down; 5 = all plants over badly. ,
Maturity Date
This is the date when the pods are dry and most of the ,
leaves have dropped. Stems are also dry, under most conditions.
Maturity may also be expressed as days earlier   or later (+) ‘
than that of a standard variety. Maturity dates were not record-
ed at all locations.
Height
Plant height was measured in inches from the soil K
surface to the tip of the main stem. .
INTERPRETATION
An important step to profitable soybean production is ».
to select good seed of the best variety. The Kentucky Soybean
Performance Tests are conducted to provide information useful
in making this selection.
Performance of soybean varieties is affected by many
factors including season, location, soil type, and time of plant-
ing. A particular soybean variety is adapted for full—season
growth in a band approximately 100 miles wide from north to
south. Thus, the best variety in northern Kentucky may not be
the best in southern areas. For this reason the Kentucky Soy-
fbean Perfonnanee Tests are conducted at several locations in
the major soybean-producing areas of the state. Data from the a
location nearest to a particular soybean grower’s farm probably
provide the best estimate of the potential of the soybean
varieties in that area.
Performance of the varieties will vary from year to year.
The average performance of a variety over a period of years
provides a better estimate of its potential than its performance
in a particular year.
4

 Small differences in yield are usually of little impor-
, tance. The yield of two varieties at a single location may differ
 _ because of chance factors (difference in soil characteristics,
fertility, or availability of moisture) even though the inherent
‘ yielding ability is the same. To decide if an observed yield
difference is real, use the LSD (least significant difference) value
C quoted at the bottom of the tables. If the difference in yield is
A greater than the LSD value, you may be reasonably certain that
( the entries actually do differ in yielding ability.
RECOMMENDED VARIETIES
The soybean varieties recommended by the Kentucky
Agricultural Experiment Station for use in Kentucky are listed
in Table 1. These varieties have been tested for a minimum of 3
years in Kentucky and have been shown to be superior in yield
and other agronomic characteristics. Varieties not on the recom-
V mended list are included in the tests to evaluate their potential,
- and some may eventually be added to the recommended list.
Table 1 also lists the characteristics and disease reactions of the
recommended varieties.
Variety Adaptation
Early—maturing varieties (Group III), such as Calland and
- Williams, are best adapted in areas of Western Kentucky north
‘ of the Western Kentucky Parkway. Late—maturing varieties
(Group V), such as Dare, York, and Hood, are best adapted in
areas south of the West Kentucky Parkway. Mid-season varie-
ties (Group IV), such as Cutler 71, Custer and Kent, can be
successfully grown in most areas in Western Kentucky.
Certified Seed
Always plant high quality seed of recommended varie-
ties. Certified soybean seed is a reliable source of good seed.
Certified seed has passed rigid field and laboratory standards for
genetic identity and purity of a variety. Certified soybean seed
also has good germination and freedom from noxious weed seed
