Exhibits on a wide range of
agriculture - related topics
will be featured at the 1977
Ag Progress Days.
According to Harry A.
Carey, Extension exhibits
specialist, the departments
of agricultural economics
and rural sociology at Penn
State will have a display in
action that uses a computer
terminal to demonstrate the
use of linear programming
in making farm
management decisions.
Another popular Penn
State exhibit will include live
speciments of common
weeds that are a problem to
both farmers and
homeowners in Penn
sylvania. Visitors to the
exhibit tent will be able to
get assistance from experts
on how to control these weed
pests.
Also among the exhibits
will be information on
honeybees, forestry, solar
energy for greenhouses, soil

contests slated
UNIVERSITY PARK -
Pennsylvania’s best
plowmen will compete for
awards in two contests held
as part of the 1977
Agricultural Progress Days
at The Pennsylvania State
University’s Rock Springs
Agricultural Research
Center.
“On August 23, about 25
contestants will compete in
the State Plowing Contest.
All have been declared
winners in county
eliminations," said N. Henry
Wooding, Penn State Ex
tension agircultural
engineer.
The State Plowing Contest
will feature three divisions:
contour; large plow, level
land; and small plow, level
land. Plowing will start at 10
a.m. Contest awards will be

same day.
The following day, August
24, all plowmen who have
won state titles, this year
and in the past, will compete
in a special contest to
determine who will
represent Pennsylvania in
the U.S. Plowing Matches
scheduled for September 14-
15 in Illinois.
“This State Plowing
Champions Contest will get
underway at 10:30 a.m.,”
Wooding points out.
“Plowmen will compete in
small plow and large plow
divisions only and awards
will be presented at 3 p.m. at
the field days.”
The matches are under the
direction of the State
Plowing Contest Committee.

and fertility studies unearthed
possiblities and productivity
of various forage species and
varieties, according to Dr.
William C. Stringer, forage
crop management resear
cher. Shown will be ex
periments with legumes and
cool-season grasses. In
general, these studies are
managed to simulate hay
harvesting or rotational
grazing.
Stringer said tall fescue
and Reed canarygrass have
yielded best among the cool
season grasses, followed by
orchardgrass - with smooth
bromegrass and timothy
giving the lowest yields.
However, timothy is usually
the most digestible.
“Our goal is to take results
from small plots such as you
will see at Rock Springs, and
at other locations over the
state, and incorporate them
into management systems
on a large scale.
“The experiments have
agronomists, animal and
dairy scientists, economists,
and engineers working
together to determine the
feasiblity of proposed
management systems. By
using good management

he affirmed.
Visitors to Ag--Progress
Days will see plots
evaluating the effects of lime
and phosphorus on yield and
nutrient composition of no
tillage corn and alfalfa. Plots
tilled with both a moldboard
plow and a disk harrow,
versus plots with minimum
tillage from a disk harrow,
will be compared for grain
yields and nutrients in
tissues.
Heading up these ex
periments is Dr. Jon K. Hall.
Last year, said Dr. Hall,
corn yields in the studies
varied significantly with
tillage treatment but not
with application rates of

study, no-tillage and
minimum tillage corn
yielded 6 to 10 more bushels
per acre than com planted
conventionally.
Other research at Ag
Progress Days will show
studies of nitrogen sources
on no-tillage com. Surface
application of four sources of
nitrogen is being compared -
urea, nitrogen solution,
ammonium nitrate, and
ammonium sulfate. A fifth
source, anhydrous am
monia, is injected into the
soil. Dr. Richard H. Fox and
associates are. testing the
extent of nitrogen lost as
ammonia gas from the five
nitrogen sources.
Visitors August 23 to 25 will
see plots where nitrogen was

applied to no-tillage corn at
zero, 45, SO, and 180 pounds
per acre. Dr. Fox indicated
that rains falling soon after
the fertilizer is applied
reduce greatly the chance
for losing nitrogen gases.
Nitrogen sources for no
tillage corn in 1975 and 1976
were compared for 20, 65,
110, and 200 pounds of total
nitrogen per acre. There
were no yield differences
among nitrogen sources
either year because of rain
that fell within two days
after nitrogen was applied
both years. Maximum yields
were obtained with 110 and
200 pounds of nitrogen per
acre both years.
Ag Progress Days is the
largest outdoor agricultural
event of its type in the East.
