In performance testing of
the oat varieties, tests were
conducted at three locations
in the state. Results from
these experiments will be
used in establishing a list of
varieties recommended for
use in Pennsylvania. Ten
varieties will be recom
mended in the 1976
Agronomy Guide.

perimentation, major em
phasis was put on: (1)
variety trials to determine
feed value per acre,
especially as calculated in
conjunction with milk
production costs; (2) an
thracnose and bacterial wilt
on alfalfa; (3) forage fer
tilization; (4) forage pests
and diseases; and (4) forage
management.
Richard Cleveland,
specialist in forage crop
management, pointed out
that anthracnose can wipe
out an entire alfalfa field by

year especially where
summers are hot and humid.
"It causes a lot more
damage than is apparent,”
the scientist stated,
‘‘especially once it has gone
through a winter." He in
dicated that the signs of
anthracnose and bacterial
wilt are yellow stems and
leaves. Arc and Serenac AR
were the two varieties of
alfalfa found to be superior
in Lancaster County.
Experiments with
crownvetch are not yet as
complete as similar
research projects with other
forage crops. The plant has
been found to be excellent
when used for highway bank
stabilization and erosion
control, but comparatively
little is known so far about its
value as a feed. In yield
trials, it was found to be
equal to birdsfoot trefoil and
better than milkvetch and
Kura clover. John Shenk,
plant breeder involved in
calculating net value of
forage crops in terms of “net
income of animal products
per acre,” emphasized that
there is a growing im
portance in knowing how
much a plant is worth as a
milk or beef producer.
In other, related ex
periments, scientists worked
on finding forages which
give maximum TDN
readings thus making
maximum use of the plants
themselves. Also, ex
periments were conducted to
raise crops with higher
contents of available
magnesium to reduce the
grass tetany problem or
possibly even eliminate it.
The alfalfa blotch leaf
miner, a European insect
which was introduced into
New England, in about 1969,
and has spread to the
Keystone state and other
areas since then, is of con
siderable concern to Penn
State agronomists. The
damage caused by one mine
per leaflet, scientists ex
plained, can be measured as
a loss of 16 per cent of the
protein, 23 per cent of the
Available in four basic sizes to fit
los from 12 to 30 feet m d
carbohydrates and 13 per
cent of the weight. As many
as 25 per cent of the leaflets
can have up to three mines.
No insecticides are
registered for use against
this pest, which has the
potential of developing four
generations to a field within
one crop year. Researchers
in New York, New England,
and Pennsylvania are
working with various
materials which will
hopefully control the leaf
miner effectively and safely.
Nathan L. Hartwig, weed
specialist at Penn State,
concerned himself with
crownvetch as a perennial
legume cover crop for no
tillage corn. He reported that
crownvetch has great
potential as a means of soil
erosion control and noted
that soil losses still cost the
farmer more per year than
weeds. He estimated most
fanners lose approximately
50 dollars per acre per year
due to soil erosion as com
pared to 40 dollars per acre
per year lost to weeds.
Besides its advantages in
reducing erosion and surface
water run-off, crownvetch
has the capacity of nitrogen
fixation thus i educing the
need for large amounts of
nitrogen fertilizer. When
used with no-tillage corn, the
excess nitrogen produced by
crownvetch becomes readily
available to com.
Established crownvetch
will not be wiped out by any
of the presently recom
mended herbicides for no
tillage com, according to
studies undertaken at the
University, and after
establishment it will tolerate
suggested levels of atrazine
or simazine.
Crownvetch can best be
established for no-tillage
corn by first making sure the
field has been limed or the
soil pH is close to neutral.
There are several methods
for weed control, depending
on conditions. The simplest
way to seed crownvetch is
the same way any other
legume crop, and this may
be done anytime from just
before planting to just before
the com comes up. Early
planting up to two or three
weeks before corn planting is
not recommended since the
herbicides will not last long
enough to give effective
weed control in corn.
Penn State researchers
are also experimenting with
no-tillage or minimum
tillage winter wheal, winter
barley and spring oats in
crownvetch. “This may
indeed be the beginning of
the green revolution for
Pennsylvania and any other
place in the world having a
humid, temperate climate
similar to ours,” exclaimed
Hartwig.
How To Remove
Berry Stains
To treat berry stains,
scrape up any berry pieces
immediately and sponge the
spot with cool water. Later
blot with a detergent-water
solution and rinse in clear
water. Mrs. Ruth Ann
Wilson, Extension clothing
and textiles specialist at The
Pennsylvania State
University, says if the fabric
is colorfast and the above
method doesn’t work, try
pouring boiling water
through the fabric stretched
over a bowl or pan. On non
colorfast fabrics, work in
glycerine and let it stand for
a few hours. Apply a few
drops of vinegar and rinse in
clear, cool water.
