_ ANNUAL REPORT
of the
DIRECTOR OF THE
KENTUCKY AGRICULTURAL EXPERIMENT STATION
For the Year 1921
The demands upon the Experiment Station have greatly
increased during the past year as evidenced in many ways and
particularly by the increased number of requests for specific
information and for bulletins. Frequently these requests have
arisen through the pressure of new problems, and in meeting
them the Experiment Station has been taxed to the utmost in
the use of its men, buildings and equipment. In many in-
stances, it has been found impossible to enter upon promising
' lines of investigation because of insufficient funds and equip-
ment. The effect of this inability will inevitably be reflected
in the progress of farming in the state, for in many lines of
. farm endeavor, progress halts for lack of information or farm-
ers suffer heavy losses in attempting individually to meet their
problems.
Agricultural extension work undoubtedly has been rc-
sponsiblc for a part of the increased demands upon thc Ex-
periment Station. Also as farmers become interested in the
possibilities of improving their income through better opera-
tion of land a11d livestock, they find many problems in which
they need help. Some of the questions that arise are old and
easily answered. In others, new problems become apparent
and require careful and extensive investigation. The intro-
duction of new crops, the use of improved methods in the feed-
ing of livestock, the revision of methods of rational and per-

 `K; 2
. 12 Thirty-Fourth Amzzzal Report
manent soil building, bring to farmers an early recognition of
the fact that the only institution in a position to help in the _
study of the essentials of these problems is the Experiment
, . Station. Its usefulness to them is largely dependent upon its
forwardness in anticipating the agricultural problems that will
T require solution. Similarly the livestock farmer and the veter-
t - inarian are largely dependent upon,the Experiment Station for
careful and det·ailed diagnosis and treatment of new epidemics
p and diseases. As an illustration, the veterinarians of the Ex-
  periment Station, during the year, located three herds in-
i fected with the fatal Johnc’s disease, a disease reported to be
E common in the Jersey Isles, but unfamiliar to the breeders in
this country. Prompt diagnosis and advice as to preventive
treatment have probably resulted in saving the owner a large
part of a valuable herd. Similar examples of the practical ap-
plication of the scientific work of the Experiment Station may
be cited in every Held of agriculture. The only limit to the as-
sistance that may be given agriculture in the state is the limit
, of the support given to the Experiment Station.
, The present support of the Experiment Station is entirely
inadequate to enable it to meet even the more pressing prob-
lems. The area of farm lands owned by the Experiment Sta-
tion should be increased to at least six hundred acres. liittle
f additional progress may be made in the conduct of soil and
, crop experimental work at the Kentucky Experiment Station
  until more land is available.
  During the past year, the more pressing needs of new in-
vestigations in the state have been '-analyzed. The following
; problems are state-wide or almost so but may not be fully un-
, dertakcn or are awaiting action until added support is avail-
v able.
1. Investigation of the method of control of diseases affect-
ing tobacco and corn.
` 2. Investigation to develop more economic methods of ap-
plying the principles and practices of soil building.
3. A detailed soil survey of all important agricultural coun-
ties. —

ay Consideration of the needs of tl1e Experimentl Station
  should proceed upon tl1e premises that {lll appropriation to ther
nit Experiment Station is not 2111 expenditure but an investment
t»hat brings constantly increasing returns to tl1e farmers and
qlv citizens of the state. For example. the average annual ex-
  penditure for soil fCl.’l1lll}' ·ll1)V(‘SllQ`2lll<)1lS is approximately-
dm- $13,000. I As a result of t·l1e influence of o11e expernnent field
HO &ll1(l tl1e information it gave upon methods of S0ll·l)llll(l1I'1jg', one
1 county that had not previously used limestone. 111 a period of
tm tl1ree years limed 7000 acres. lf this lime was used without
Km phosphate, the increase in crop yields for a period of 4 years,
based 11pon tl1e results obtained 011 tl1e experiment field, would 1
lll‘ — have been worth, upon very conservative estimate, $84,000
lll? above tl1e cost of tl1e limestone.
ull- lt is not known how nnich ot the limed land was also treat-
ml- `ed with phosphate, but if tl1e entire acreage had been so treat-
ed. tl1e val11e of tl1e increase i11 crops over the cost of the lime-
<"ll‘ stone Hll(l ])llOS]}ll2`tl'(‘ would ll2lV(‘ been, npon conservative esti-
mate, $154,000 for a -L-year period. as nineh as tl1e soil fertility
?lll’ investigations as a \\`ll1'1l(‘ have cost the state for twelve years.
The1·e is no means of estimating aeenrately the acreage of
mn- farm land in the state that is being treated according to the
i findings 2lll(l reeoinniedations of the lixperinient Station. It is-

 1 A   1 A
14 Tlzirtey-Fourth A·mz.ual Report
known, however, that the acreage is large and that following
the recommendations has given an increased wealth produc-
. tion. Approximately two-thirds ot the area of the state devot-
ed to staple crops requires, for best results, the lime and phos-
phate treatment. recommended by the Experiment Station.
This acreage if treated according to the findings will return ,
annually a net profit above the cost of treatment of twenty
, million dollars or an average of almost $75.00 for each farm in
l the state. On the basis ot present appropriations. assuming
4 . . 4 '
{ that iarm values carry about one-halt the taxes ot the state,
i each farm is taxed about ten cents annually for the Experi-
ment Station.
Legislation Required. An amended pure seed act should
be passed that will give greater enforcement authority and
carry an appropriation tor its administration. The present
seed law is detective in that it does not provide funds for ad-
, ministration and in instances is not; tully enforceable.
The nursery inspection act also is inadequately financed.
An appropriation should be made that will enable a tull service
to the nurserymen and farmers. Under present conditions, it
A is an additional financial burden to the Experiment Station.
t New Projects. The following projects have been initiated
¤ during the year: i
Y The pathology and bacteriology ot the reproductive or-
. . . · . .
gans of the mare and their relation to sterility.

Dairy Cattle. Valentine ’s Ashburn Baronet, 100041, bred
by the Kentucky Agricultural Experiment Station and sold
d_ to J. M. Dickson and Son, Shedd, Oregon, was recently award-
ed a gold medal by the American Jersey Cattle Club, because
of the excellence of the heifers sired by him. Only fourteen
Jersey bulls have been awarded such an honor and of this num-
ber, Valentines Ashburn Baronet is the only one ever bred by
an Agricultural College or lixperiment Station. This bull is a
s grandson of Dollie’s Valentine, the foundation cow of the Ex-
periment Station herd. The average production of his 16 test-
ed daughters is 8222 pounds of milk and 470 pounds of butter
fat. His three highest daughters produced an average of 739
pounds of butter fat.
