cultural Field Day" IN which %.
boys from various high schools OF
| the state took part. This day was
Z set apart so that the agriculture
pupils OF the State might observe
the experiments and other work be-
ing carried on at the Delaware Ex-
pertinent station.
The first point OF interest in the
tour at the University grounds was
the Agronomy Plots. In these plots
there were different experiments
being tried In crops. cover crops
Fertilizers. manure. lime and crop
rotations The crops included corn,
soy beans. wheat and timothy and
clover hey. This makes a good ro-
tation for this section. The corn
was followed by rye and vetch as
"a cover crop. Each OF these plots
was divided into l6 plots. cantain-
ing 1-1O acre each. and were ferti-
lized with every possible combina-
ton OF fertilizers. manures and
lime.
In the wheat experiments where
wheat was grown continuously the
12-year average. with tons OF ma
nura yielded 24.1 bushels. while the
check plot yielded only j. bushels.
with a complete fertilizer the aver
age yield was p bushels 7'he COM
plete fertilizer doubled. yielded %
bushels. In this experiment it will
be seen that doubling the amount
n complete fertilizer as not as prot
table as using half of the amount.
However. there Is no doubt that the
use OF some fertilizer is more prof
table than omitting Il altogether.
The profit realized from manure or
fertilizer depends on the farmers
conditions
In the corn experiments where
corn was grown continuously. a
complete fertilizer increased thu
yield 35 TO 40 bushels per acre over
the check plot. with the same fer
tilizer whsn crop rotation was
practical. the yield was increased 10
to 20 bushels more than the con-
tinuOus crop plot. Lime with fer
tiliZers as manure increased corn
yield 10 10 bushels per acre. with
out fertilizer lime gave negative re-
suits.
In the SOY bean experiments a
complete fertilizer or manure in
creased the yield 10 To is bushels
and hay p to / = tons per acre
over the check plot Lime with
muriate OF potash or manure in
creased SOY bean yields about y
ton per acre with or without ferti-
lizers.
One general conclusion in the ex-
periments at the University Is that
the fertility OF the soil cannot be
kept up by rotation alone. Another
is that rotation increases yield very
much.
The next point OF interest was
the dairy harms. There. we observ-
ed a fine herd OF Holstein cattle.
The breed satisfies the purpose OF
that community better than any
other breed. Also in the keeping
OF only one breed IL Is possible TO
exchange bulls with a nearby herd
and thus improve the quality Of the
stock. The barns were In a sani-
tary condition, indicating good
dairying management.
When this herd was started IL did
not contain any high record ami
mails but by the proper handling
and breeding the herd has been
greatly improved. over a half OF
the COWS have made advanced regis
try records. Two COWS have made
over 500 pounds OF butter and sew
eral have made nearly 500 pounds.
In one end Of the barn was a
first class bull. The one fault OF
this bull was that he was too fat.
We were informed that this was be-
cause he he'd been put in such con-
dition for the State Fair in which
he has won first prize for three
years. The breeding stock should
be spare fieshed. In a few years
experience Il has been proven that
t pays TO develop the young stock
-ather than buy well developed old
er stock. The bull should not be
oiled as a rule before his offspringl
has made some kind Of a record. n
lis daughter has made a high milk
-ecord and the bull has been killed /
[ is too late 10 breed again for i'm /
proved stock. This is a very good |
dea as II is much cheaper to de- I
-elop the young stock rather than /
,uy high priced herd 10 start with. /
The next place we visited was the
iog department. Here were three /
u the leading breeds. Brkshires. Po-
and Chinas and Durco Jerseys.
The hog lots are so arranged that
ape pasture may be supplied all OF
he season which il will grow. This
. a very economical way OF pro-
Iucing pork. A feed house was To-
ated in the center OF the hog lois
rom which a track led to all OF
he hog lots. over which all Of the
eed is carried TO the various lots.
mixtura OF 35 lbs. of tankage. 35
5s. Of peanut meal. 800 lbs. Of hom-
ny and $50 lbs. OF middhngs Is
ed in a self-feeder. A slop is also
cd in troughs. The water is SUD-
lied by means OF self-feeding de-
ices.
The gilts are bred only once
he first year. but after that they
Ie oieu Twice a year. breeding
vice the first year has a tendency
D stunt the gifts growth. There
re two types OF hog houses in
Sc. the A shaped and the Iowa
'pe. The Iowa type is preferable
, the A shaped. as 1t gives more
pom to work and also more air
pace. The extra expense OF the
owa type is paid for in the CON
anience q affords.
From the hog departm snts we
sited the poultry department.
here are two houses which are
Dnnected by a feed house in the
'nter. This makes Il very con-
anient in feeding and caring for
