If quick tests indicate that the soil is moderately or strongly acid
use ground limestone at rate of 2 or 3 tons per acre respectively; if low in
available phosphorus use fertilizers to supply up to 80 pounds of P205 per acre;
and if low in available potassium use fertilizers to supply up to 80 pounds of
X?O per acre. Apply limestone and fertilizers either before or after plowing.
T6 avoid injury to seedling soybeans, do not drlll fertilizer in contact with
the seed. Soybeans respond well to the use of needed lime and fertilizers on
other crops in the rotation ahead of the soybean crop.
 
The soybean variety tests reported herein were designed for the evalu— 4
ation of varieties which are commonly grown or appear promising for use in Xen-
tucky. The fertilizer test was designed to test the response of soybeans to the
addition of lime, phosphorous, and potassium to the soil, either singly or in
various combinations and according to the need as indicated by rapid chemical
~ tests of the soil. The results of the uniform tests of experimental strains of
soybeans conducted at Henderson and Lexington in cooperation with the U. S.
Regional Soybean Laboratory, Urbana, Illinois, are reported in their Progress
Report, RSIM 178, March, 1956. _
The locations of the various tests are indicated in Hg. l. The Hen-
derson county and Hicknsn county tests were located ln the mln soybean-pro-
ducing areas of the state on bottomlands of streams which are tributary to the
Ohio and Mississippi Rivers respectively. The Fayette county test was located
on upland soil of central Kentucky.
Method; Used
The variety tests were planted in *4-row plots with three replications
and in a randomized block design. The rows were 19 feet long and 36 inches
apart in the Fayette and Henderson County tests and no inches apart in the
Hickman county test. A 16-foot section was harvested from each of the two
center rows. Beans were planted at a rate of l2 seeds per foot of row. The
2

 fertilizer test at Henderson was planted with Clark variety in the e ae manner
as the variety test at that location except that rows were no feet long, and
the treatments were in quadruplicate. Commercial inoculant was used on seeds
at time of planting ln all tests except that in Fayette county where inoculated
beans had been grown on the land the preceding year. The attempt was made to
follow best cultural practices at all locations.
zgglgpg Seed weights were recorded after the seed of all plots
had reached a uniform moisture content.
Oil cgntent: Percent of oil was determined from a composite sample
of seed from all repllcatlons in each test. Analyses were made at the lxperiment
Station chemical laboratory. Percent oil is expressed on moisture-free basis.
Seed Sgze is reported as weight in grams per 100 seeds.
Lggg;gg_ngpgg were recorded at or near maturity according to the
scale shown in footnote to each table.
Height of plants was determined as the average length of plants in
a plot from ground to the top extremity at time of aaturity.
ygtgplgy ls taken as the date when the pods are dry and most of the
leaves have dropped. It is expressed as days earlier (-) or later (+) than
Perry as a reference variety.
Sged Quallty is rated from l to 5 according to the scale shown as
a footnote to each table.
Lnterpretgtgog gf Data
The difference in yield between varieties or soil treatments necessary ‘
for reasonable assurance that such an inherent yield potential exists, has been
calculated and is given in a footnote to each table. Unless the yields of the
two varieties or the two soil treatments being compared differ by as much as or
more than the figures shown, little confidence can be placed in the apparent
superiority of one variety or soil treatment over the other under the conditions
of the particular test.
Data on agronomlc characteristics other than yield have not been ana-
lyzed statistically: however, small differences between any two varieties or
treatments are likely to be of little importance and should not be considered
strongly indicative of a true difference.
Duratigg of Tests: The results of evaluating varieties or soil treat-
ments over a period of several years are more trustworthy than those from a
single year. A glven variety may be outstanding in performance one year and
_ show less desirable characteristics another year. Results over a period of
years tend to average these fluctuations. Where available, yield data for
more than a single year are given in the tables along with those of 1955.
