Richard Rivlin, M.D., reviews materials wtih Pamela
Rusnak, nutrition consultant for Dairy, Food and Nutrition
Council, prior to his recent presentation in Danville, on
"Calcium Research: The Latest Findings." Over 40 health
professionals including physicians, dietitians and nurses
attended the program on calcium sponsored by Geisinger
Medical Center and Dairy, Food and Nutrition Council.
Calcium Research
According to Dr. Rivlin surveys
show that as much as half of the
U.S. population over age 65 isn’t
getting the recommended amounts
of several key nutrients in their
diet including calcium.
Dr. Rivlin is a professor of
medicine and chief of the Nutrition
Division at New York Hospital -
Cornell Medical Center. He is also
the chief of Nutrition Services at
Memorial Sloan-Kettering Cancer
Center.
Broken hips and crumbling
vertebrae are among the painful
hallmarks of osteporosis, the
“brittle bone” disease associated
with too little calcium in the diet.
FLO-STAR” claw
Bou-Matic®’s Flo-Star™ milking claw
improves milk flow for:
• Better cow health
• Faster milk throughput, and
• Better milk quality.
Bou-Matic engineers designed the Flo-Star claw so milk flows
smoothly and quickly out the bottom.
Less agitation equals less chance of milk “mist” carrying bacteria
among teats. So the Flo-Star claw can mean less mastitis spread at
milking.
Prove it to yourself by calling your Bou-Matic dealer for a free, on
farm demonstration.

Dr. Rivlin noted that adequate
calcium throughout life can help
keep the bones strong and healthy.
Dr. Rivlin said, “It’s important
for everyone to realize that what
we eat in our younger years will
have a direct impact on our
health.”

Yocum Honored For 25 Years of Service
Penn State’s Southeastern Field
Research Laboratory in Lan
disville has a long history of ser
vice to regional fanners and to
university researchers. It also has
a dedicated head.
John 0. Yocum, senior research
associate in agronomy and
superintendent of the laboratory
will be honored at an awards
ceremony Nov. 21 for his 25 years
of service to Penn State and the
College of Agriculture.
As head of the field lab, he
supervises variety trials for com,
soybeans, forage crops, small
grains and tobacco and coor
dinates the research on weed
controls and fertility testing. Other
crops tested at Landisville include
potatoes, grapes, and annual
flowers. His own research is
focused on field studies of
agronomic crops and breeding •
tobacco varieties. Yocum is the
only extension specialist for
tobacco in Pennsylvania.
Penn State owns 110 acres at
Landisville for research in Penn
State’s Departments of Agronomy,
Horticulture, Plant Pathology and
Entomology. Yocum works closely
with extension agents and farmers
in the southcentral and
southeastern region of the state.
He also cooperates with other
researchers on trials and fertility
with cooperating farms in the
region.
The Landisville staff includes
two biological technicians, a
secretary, (Sandra Yocum, who
also worked at the lab for 23 years)
and field help in the summer. “I
like to hire our own Penn State
students when I can. It is a great
way for them to put their learning
to use.”
“In the early years it was stoop
and haul nearly
everything was planted and
harvested by hand, he says. “Now
most planting and harvesting is
done mechanically except some of
the corn nursery, which is still
harvested by hand.” In addition
mechanization has allowed us to
accomplish a tremendous increase
in field research. Computers have
also become a tremendous aid to
research.
Another difference he notes is
the increased use of chemical
controls. “In the future I am sure

we will see more use of integrated
pest management, en

more biological controls as the
research results of biotechnology
become available.”
Looking to the future, he says
“southeastern Pennsylvania is
dominated by animal agriculture
so I see a continuing need for our
work in com, small grains and
forage crops. However, our farm
ers are becoming more in
terested in horticultural crops as a
cash crop, especially since we are
so close to urban markets.
Muskmellons, tomatoes, peppers,
cucumbers and fall cauliflower are
grown increasingly in this area. In
response, I anticipate more hor
ticultural research involving
faculty in the College of
Agriculture.”

Agronomy. The guide is widely
used by county extension agents,
vocational agriculture teachers,
farmers and by industry for its
unbiased recommendations on
pest controls, fertility and
management practices.
He received both his B.S. and
M.S. in agronomy from Penn State
and has served as president of the
Northeast Society of Agricultural
Research Managers. He is a
member of the American and
Northeast Societies of Agronomy,
the Crop Science Society and the
North East Weed Science Society
and belongs to Alpha Zeta and
Gamma Sigma Delta, honorary
agricultural fraternities.
Yocum has been president of the
Manheim Rotary Club, vice
president of the Manheim Farm
Show and has been involved in the
local PTA and a number of young
farmers groups in vocational
agricultural programs in regional
high schools.
Not fond of commuting, he and
his wife live where they work in
a house on the field lab grounds.
“The only disadvantage,” he says,
“is that if I take a vacation at
home, I’m still at work.” The
Yocums have two daughters;
Jennifer, who received a B.S. in
plant pathology at Penn State and
is finishing her masters at the
University of Delaware, and
Jeanne, who works with the YMCA
in Lancaster.
When he’s not working with
fanners, extension agents or
researchers (which is rare), he
enjoys fishing and hunting small
game and deer. He also enjoys
landscape painting and intends to
get back to it some day.
