 ' RESULTS OF EXPERIMENTAL TESTS
AT WESTERN KENTUCKY EXPERIMENT SUBSTATION
1927 - 1954 . `
At the Western Kentucky Experiment Substation
V research projects are conducted in agronomy, horti-
. culture, livestock, and poultry work. Some of the re-
sults are given in this summary. Y
AGRONOMY
The soils and crops work, conducted on approxi-
mately 1, 500 plots, consists of long -ti:ne fertility PT°'
jects with corn, wheat, hay, and tobacco as well as
anumberofvarietytests. Results offertility projects,
E located on limestone and sandstone soil, are given in
the summary. Both soils are representative of large
areas inwestern Kentucky. All variety t e s t s are con-
ducted on limestone soil. Varieties of corn, small
grains, burleytobacco, and darktobacco are compared
each year as to yield, quality, and disease resistance.
Also, numerous varieties of legumes and grasses are
being tested. Thesetests are changed somewhat from
year to year to incorporate new varieties.
In most of the experiments, the yields or other
data are the averages of from three to six replicated
` plot. The difference necessary for significance be-
tween any two treatments or varieties is computed by
statistical analysis. This difference is given at the
foot of the tables as L. S. D. (least significant differ -
ence) atthe 5-percent level. Unless the difference be-
V tween any two treatments or varieties being compared
is as much as the significant difference, little confi-
dence can be put in the superiority of one over the
other under the conditions of the particular test.
ln several of the long -time fertility projects eve ry
third plot is a check plots. These check plots all re-

 ..4-
ceive the same treatment so as to measure the varia- _
tions in the natural productivity of the soil. The re-
sults ofthe tests are given in terms of adjusted yields.
The average yield of all the check plots in an experi-
ment is given, and the yields for the treated plots are 1
adjusted yields obtained by adding the increase for the it
treatments to the average yield of the check plots.
Lime and Fertilizer Experixnents on Limestone Soil ·
From 1927 to 1944 an experiment was conducted
comparing the effect of ground limestone on crops, in
respect to different times of applications and also differ-
ent sizes of particles. A three —year rotation of(1) corn,
(2) wheat, and (3) legume and grass hay was followed. y
There was verylittle difference in drop yields, whether
the limestone (2 tons) was all applied at the beginning
of an 18-year period, 1 ton each 9 years, or l/3 ton in
each 3-year rotation. As for the l/3-ton applications,
there was no advantage in having the lirnestone finer
than 10-20 mesh. In those tests, the amount of man-
ure applied was equal to the weight of crops removed,
except wheat grain.
This projecthas now been revised. Beginning with
the 1949 corn crop, manure has been omitted from all
but tW0 Plcts Where it is now used at the rate of 8 tons .
per acre of cern- Superphosphate, fused phosphate,
and triple superphosphate are applied at the rate of 90
pounds of PZOS and rock phosphate 180 pounds PZOB
per acre ahead of wheat. Muriate of potash is applied
at the rate of 60 pounds KZO ahead of wheat. Ammon-
nium nitrate is applied at the rate of 15 poundsN spring
top -dressing on wheat and 50 pounds N broadcast ahead
of corn.
The average adjusted yields from plots of certain
treatments in the present project are shown in the fol-
lowing table. (See statenaent on page 3 concerning ad-
justed yields.)

Trace Elements for Alfalfa on Limestone Soil
A top —dressing of the trace elements ¤‘1&g¤€$iL1T¤,
` manganese, iron, coppe r, zinc, and boron on lime -
stone soil was applied May 20 following the first 1954
cutting of alfalfa sown in August 1952. One treatment
c o n s i s te d of all the trace elements. A check treat-
‘ ment with no trace elements was used and also a treat -
ment with only boron as the trace element. A fourth
treatment consisted of all the elements except boron.
» A fertilizer top-dressing of O-100-120 was applied on
all plots.
Three cuttings following treatment were made on
june 15, ]uly21, and September 9. Differences
between yields were not significant at the 5% level. This
field had previously been treated with boron at time of
seeding.

Variety Tests
Corn Varieties: This test is primarily for the e-
valuation of experimental hybrids developed by the Ken-
tucky Agricultural Experiment Station in its breeding
program. Also included are experimental and com- A V
mercially available hybrids developed by other State
and federal agencies, and several privately controlled
hybrids. Seed of privately controlled commercial hy-
of s tate or federally controlled hybrids was obtained ~
from the res ective ex eriment stations or from row- .
. . P. g .
ers of certified seed. Yields are reported as bushels
per acre of shelled corn corrected to 15.5% moisture.
Corrections are made for mi s s ing hills, but not for
minor variations in stand.

Dark Tobacco Varieties: Thirty of the best known varieties of
dark tobacco in western Kentucky have been compared in tests start-
ed in 1926. The more desirable of these have been in the tests for
periods ranging from 16 to 25 years. The testing of new varieties
is much the same as in the burley variety test in thatdisease-resis- l
tant strains are being conipared for yield and quality. R€$¤1t5 Of I
recent tests are shown in the following table:

Characteristics of burley tobacco listed:
Ky 16 — Amoderatelyroot-r0t—resistantvariety intro-
duced in 1935. It is a stand-up type and well
adapted to burley producing areas. It slows
growth during adverse weather and does not
"spindle up."

 -17-
`* Ky 57 - A varie ty highly resistant to black root rot
and resistant to m 0 s a i c. The yield is very
good, and the quality is high. It is similar in
appearance to Ky 56 but seems to be slightly
V higher yielding and of better quality.
‘ Ky 26 - This is a hybrid of Golden Burley with a high-
ly root—rot—resistant burley. lt is a stand-up
type, somewhat more resistant to black root
rot than Ky 16, of nearly equal yield, and of
very good quality. Higher in nicotine than
most widely grown varieties.
Ky 41A- Similar to Ky 16 in resistance to black root
rot. It is not a typical stand-up variety. Ky
4lA is one of the lower nicotine varieties.
Ky 35 — A stand-up type whichis moderately resistant
to black root rot and fusarium wilt, and resis-
tant to mosaic. It is subject to damage from
cool weather (may bloom prematurely), corn
pollen, and veinbanding virus transmitted by
aphids from potatoes. It is slightly higher in
nicotine than Ky 4lA.
Ky 58 - A stand-up variety, highly resistant to black
root rot and resistant to mosaic. It is mod-
erately high yielding and is lower in nicotine
than Ky 57.
The other varieties listed are all experimental va-
rieties, with various degrees of disease resistance,
which are being tested for yield and quality. Those va-
rieties preceded by the letters "WF" are wildfir€·1‘€·
sistant lines. Progress is being made in developing a
variety which has combined resistance to black root
rot, mosaic, wildfire, fusarium wilt,and black shank.
Selections are being made for lower nicotine content.

Forage Crops (on limestone soil): Variety studies
of several legumes and grasses are being made to de- `
termine the adaptability of new varieties. All yields
are given as pounds per acre of air-dry forage.
ALFALFA — S ev e ral new varieties of alfalfa are
bein  determine their value as compared with
recommended varieties. Origin and characteristics
of new and recommended varieties are given below:
Narragansett is a variety developed at the R hode
Island Agricultural Experiment Station by mass selec-
tion. It apparently has some tolerance to leaf diseases;
the foliage is dark green; the crowns are wide, and the
stems are usually e r e c t. Small amounts of certified
seed will be available in 1956.
Du Puits is avariety originatedin northern France.
It is vig or ou s, upright in growth, dark green, with
some r e s i s ta nc e to leaf diseases but susceptible to
crown rot, anthracnose and bacterial wilt. No certi-
fied seed is available. '
Williamsburg was developed at the Virginia Agri-
culturalExperiment Station. Further testing is neces-
sary to evaluate this variety.
B uf fa l o, recommended for use in Kentucky, was
developed at the Kansas Agricultural Experiment Sta-
tion by close breeding and selection out of Kansas Com-
mon. lt was selected for its resistance to bacterial
wilt(not important in Kentucky) and for its high produc-
tion. Certified seed is plentiful.
Atlantic, also recommended for use in Kentucky,
was developed at the New Jersey Agricultural Experi— .
ment Station by mass selection out of more than 100
strains and varieties. It is a variegated alfalfa, dark
green, and is somewhat tolerant of leafhopper attack.

 1 -19-
. It is the highest—yielding alfalfa thoroughly tested in
Kentucky. Certified seed is plentiful.
I Ranger is a multip1e~strain va rie ty synthesized
_ .V from Cossack, Turkistan, and Ladak at the Nebraska
Agricultural Experiment Station and is recommended
for use in Kentucky. It is resistant to bacterial wilt.
Certified seed supplies are plentiful.
Argentine and Pilca Butta do not seem to be adapted
to Kentucky and usually winter kill.

Q
RED CLOVER - Two varieties of red clove r are Q
recommended, Kenland and Ky 215. Kenland was de# r
veloped by the Kentucky Agricultural Experiment Sta-
tion in cooperation with the U. S. Department of Agri -
culture. It yields, on the average, about 15 to 20 per- (
cent more than Ky 215 and has about 25 percent better
stand in the sp ring of `fhe third year. Both varieties
are greatly superior to commercial red clover lots.

Alabama. Rebel is anon-reseeding variety developed
by the Mississippi Agricultural Experiment S t a t i o n.
The Kentucky Agricultural Experime nt Station selection,

 . -21-
which is as yet unnamed, is very well adapted to Ken-
tucky, being possibly a little more winter—hardy than

ANNUAL LESPEDEZA — Investigations are under
way at the Princeton Substation and other areas of the
state to determine which of the varieties of lespedeza
should be recommended. Or ig i n and characteristics
of the varieties in the test at Princeton are as follows:
Kobe is a later maturing variety than any of the
other varieties, and was showing a much greener color
at the time of harvest which was late. The other vari-
eties were setting seed but still held their leaves well.
Climax was developed from commercialKorean.
. It grows a little larger and requires a longer growing
season than Korean.
Rowan is a variety of Korean lespedeza developed
by the North Carolina Agricultural Experiment Station.
It cannot be distinguished from other strains of Korean

Yields were taken when the sudan reached the head-
i ing stage. Ammonium nitrate was applied after each har-
, vest at the rate of 100 pounds per acre. Leaf diseases
were very severe at the time of first cutting but much
less of a factor at the second and third cutting. The
Greenleaf va r ie ty was the one most affected, but all
the other varieties were affected to some extent, with
Piper being the least damaged. Piper made the quick-
est return g r owt h after mowing and Sweet sudan was
considered the most leafy variety, having a much wider
leaf blade than any of the others. Piper is reported to
have a lower level of pr u s sic acid content than other
varieties. Tift and Piper are not sweet sudan g r a s s
' varieties.
