IFAS CAPS ARE HERE! Unit directors and administrators should submit all orders by
letter to the Vice-President's office, accompanied by $3.50 for each hat. Make checks to the
University of Florida Foundation, for deposit in the Student Agricultural Council account.
Orders may be picked up in Gainesville or be delivered via the IFAS Mail Delivery Service.
In the fall, further purchases go through the Student Agricultural Council, which sponsors
the project.

important for efficient metabolism, possibly year-round. Research by D. K. Beede (Dairy
Science) suggests that Florida cows need more sodium and potassium in summer and possi-
bly year-round. He is currently refining data for Florida conditions.

PILOT STUDIES ON HORSES may change worm treatment schedules for horses, says
Charles Courtney (Preventive Medicine). Research thus far indicates colic-causing worms
may best be controlled with seasonal worming instead of monthly doses year-round as
current practices recommend. Research discovery: worms gathered off two UF pastures are
100 times worse in winter. Courtney will retest at another location to confirm first results,
then try field studies.

FLORIDA 302 WHEAT ranked as highest yielding wheat variety in 1982 and 1983 regional
trials in 14 states. Due for release this year, 302 is a late maturing variety that provides a
longer grazing season for beef cattle, says R. D. Barnett (North Florida, REC). Barnett says
302 answers the need to diversify wheat varieties and is excellent for milling. Foreseen: a
high demand for the seed in southern states. In final approval stages: a new special purpose
rye, Florida 401, which gives good, early forage, says Barnett.

"SAVE WATER," A FOUR-YEAR water consciousness-raising effort underway in Boynton
Beach already has trained 15 volunteers. The joint Extension, water management district
and city project seeks to train volunteers for demonstrations, provide conservation litera-
ture, assess water use surveys, hold mini-exhibits and distribute water flow restrictors during
the first year, says Carol Ann Schiller (Boynton Beach), project coordinator. Midge Smith
(Program Evaluation and Organizational Development) currently is assessing survey data.
Thus far: about 500 families have requested educational pamphlets and volunteers will assist
in a water plant Open House this month. Schiller is monitoring water use in one condomini-
um in which all units have installed water flow restrictors.

plants, says T. J. Sheehan (Ornamental Horticulture). Research with graduate student Lee
Barnes involves growing explants from microcuttings of Rhododendron chapmanii, the only
leatherleaf-type rhododendron native to the state. Sheehan says more of the endangered
plants now can be found in IFAS labs than exist in the wild throughout Florida. Next stage:
refining the tissue culture process and rooting plants for release to the trade.

THE EXTENSION FORAGE TESTING pilot program will expand for use statewide this
summer, says Bill Kunkle (Animal Science). The near infrared (NIRS) equipment at AREC-
Ona provides Florida livestock producers with a quick, inexpensive forage quality evaluation.

J gagMOM.=

Koburger (Food Science and Human Nutrition) and marine agents Leigh Taylor Johnson
(Brevard County) and Scott Andree (Franklin County). Research thus far indicates refriger-
ated water and temporary wet storage improve survival rates, but that handling is only one
facet of the problem. Otwell believes results from this research should benefit commercial
and recreational clam fisheries and initiate support for water pollution research programs..

4-H and Other Youth Programs: Jim Northrop coordinated Florida's six-county participa-
tion in a nationwide study of early adolescents and their families. Northrop and Michelle
Luzier (Hillsborough County) attended the recent conference in Nashville where results
were presented... ."Rural Crime in Florida:" A Victimization of the Rural Nonfarm Popu-
lation", co-authored by Bo Beaulieu and Keith Carter, is now in monograph form, published
by the Southern Rural Development Center. Limited copies of the summary report which
investigates the nature and extent of crime in 33 rural Florida counties are available upon
request by calling Beaulieu .... .B. J. Allen is co-chairman of this year's National 4-H Con-
gress Tours Committee.
Bill F. Brown (AREC, Ona) won first place in the Invitational Research Paper Competi-
tion of the Midwestern Section meeting of the American Society of Animal Science held in
Chicago in late March. Topic: "Computer Simulation of Animal Growth and Animal-Plant
Interactions in a Grazing Situation."
Patricia A. Wagner (Extension Home Economics and Food Science and Human Nutrition)
participated as a witness in a Miami field hearing conducted by a U. S. House of Representa-
tives Agriculture subcommittee. Testimony addressed nutrition problems associated with
poverty, food resources and the role of education in nutritional programs.
Gary Elmstrom (Leesburg, AREC) was elected chairman of the Experimental Station
Superintendents' Section of the Southern Association of Agricultural Scientists at the
February meeting of the SAAS in Nashville.
Joe Joyce (Center for Aquatic Plant Research) and Bill Haller (Agronomy) went to Ecua-
dor this month to advise the Ecuadoran government about a water hyacinth problem in a
hydroelectric reservoir there.
Richard Miles (Poultry Science) recently returned from a two-week lecture trip in Central
America. He spoke to representatives of the poultry industry in Mexico, Guatemala, Costa
Rica and Panama on the use of fats and full-fat soybeans in poultry diets.
From Dairy Science: David Beede was an invited speaker at the International Conference
on Milk Production.in Developing Countries early this month, held at the Center for Tropi-
cal Veterinary Animpl Health in Edinburgh, Scotland. After presenting a paper on the effect
of tropical and subtropical climates on milk yield and composition, Beede visited the
famous Rowett and Hannah research centers .... H. H. Van Horn attended the Holstein-
Friesan Association of America in Guatemala City this month to judge a dairy show and give
nutritional seminars .... Barney Harris received an appreciation award from the North Flor-
ida Dairy Goat Club for his work in the dairy goat industry... .David Beede, Robert Collier,
William Thatcher and Charles Wilcox recently were awarded a four-year, $300,000 BARD
Agency grant to study the "Hyperthermal and Nutritional Effects on Milk Production."
Speaking at the May meeting of the Interamerican Dairy Congress were Robert Collier
and David Webb (Dairy Science), James Jezeski (Food Sciences and Human Nutrition).
Joseph Conrad (Animal Science) was elected vice-president of the World Association of
Animal Production at the fifth World Conference on Animal Production in Tokyo recently.

HIGHER PROTEIN DIETS FOR FORCE-RESTED layers during recovery bring laying hens
back into production with a quality product four to five days sooner, says Bruce hitmas
(Chipley Poultry Evaluation Center). His research indicates that adding higher protein
during the recovery period resulted in good shell quality and high total egg numbers what-
ever force-resting method was used. Christmas won the Kathryn Harms Poultry Publication
Award last month for his research. Now under study: shorter resting periods, which he says
may significantly reduce the non-productive period between laying cycles.

"A BIT OF A RACE," is how George Fitzpatrick (Ft. Lauderdale, REC) describes parallel
research he and colleague Ted Batterson (Ft. Lauderdale, REC) are conducting. Projects
raise terrestrial and aquatic plants for biomass production in composted sewage sludge, irri-
gated with treated sewage effluent. In the friendly competition, Fitzpatrick reports good
first-year yields for acacia and Leucaena leudocephala, or "jumbay." Batterson is similarly
pleased with yields from phragmites, or common reed. Latest 24-month samples were
recently sent to A. Shiralipour (Microbiology and Cell Science) to evaluate methane poten-
tial. Ken Portier (Statistics) will help evaluate data. Projects proceed with the cooperation of
several Broward County departments and the county's environmental quality control board.

common loon die-off last winter, according to Don Forrester (Preventive Medicine) and
graduate student Lourdes Bielsa, who are researching reasons for the die-off. Hypothesis
under test: strain of migratory flight, moulting and a dietary change due to a shortage of the
loons' favorite fish all combined to increase exposure and susceptibility to the parasites.
Origin of the mercury is still undetermined. Researchers now are collecting dietary informa-
tion from healthy loons, analyzing tissue samples from last winter's die-off and comparing
them with samples from a similar 1972-73 incident.

EXPERIENCE SHOWS THAT chlorine is critical for adequate dump tank sanitation, but no
data is available to support the need for its use, says Jerry Bartz (Plant Pathology). Bartz
and Mark Sherman (Vegetable Crops) are developing a database for chlorine use and
attempting to find alternatives adequate for dump tank sanitation.

RAPID COMMUNICATION OF cabbage marketing information contained in the Federal-
State Market News Service is the goal of a pilot project developed by John VanSickle and
Suzanna Morris (Food and Resource Economics). Though containing vital shipping and pric-
ing information, the reports often arrive by mail too late to be valuable, according to
VanSickle. Project loads the service's information onto IFAS computers for free use at
county extension offices immediately after publication in Washington. Project is already up
and going, says VanSickle. Planned: training workshops with growers and other marketing
people this month.

SHREDDED MELALEUCA SHOWS GOOD POTENTIAL to substitute for pine bark in pot-
ting media mixes for foliage plants, say Charles Conover and R. Poole (AREC, Apopka).
Melaleuca has application for woody plant potting media, too, according to Dewayne
Ingram and Charles Johnson (Ornamental Horticulture), provided the mix has no more than
50 percent melaleuca. All agree grinding the whole tree is simpler and more economical than
using only the bark. Several companies are exploring the commercial potential, says Con-
over. Jay Huffman (Forest Resources and Conservation) cooperated in both projects.

HARD CLAM SURVIVAL RATES SHOW TREMENDOUS differences according to harvest
season and bed locations, says Steve Otwell (Food Science and Human Nutrition). East
coast hard clams survived far better than those from west coast waters, and survivability
increases "dramatically" during fall and winter harvesting, Otwell says. Sea Grant project
involves three species of Florida hard clam and is conducted with the cooperation of Jack

Thomas Sheehan (Ornamental Horticulture) directed and spoke at the Eleventh World
Orchid Conference in Miami in late March. Among the 67 speakers at the three-day seminar
were W. Zettler and Nan-Jing Ko (Plant Pathology). Over 3,000 scientists registered for the
internationally-attended seminar. About 50,000 people visited the accompanying orchid
Seven IFAS graphic illustrators were among those donating art work to the Child Abuse
Prevention Project, KIDSTUFF. Those contributing: Darrae Noding, Wendy Mahon-Hils,
