REPORT OF THE DEAN FOR RESEARCH


Agricultural Research is one of the three major
divisions of the University of Florida, Institute of Food
and Agricultural Sciences (IFAS). All research is closely
coordinated with the extension and resident instruction
divisions, the other two main divisions of IFAS. The
agricultural research program is a statewide responsibility
that no other university has in Florida. IFAS research
faculty members have responsibilities in the graduate
research programs both on and off the Gainesville campus.
Research faculty also cooperate with the extension division
to extend the new research knowledge and information to all
segments of industry and society.


Within the IFAS research program there are 20 depart-
ments at the University of Florida in Gainesville and 21
research centers located throughout the state. The many
locations make possible research on different soils, under
varying climatic conditions, and on many commodities such
as citrus, vegetables, field crops, pastures, livestock,
ornamentals, tropical fruits, forests and others. While
production research receives the most attention, time also
is devoted to research in processing, handling, marketing,
utilization, engineering, and economics, including basic
research in all disciplines. Environmental and human
resource research is being given increasing attention.

A statewide program, planning and budgeting system
(PPBS) is being extensively revised this year for the
entire research program. This Research Program Planning
Memorandum has been developed around major crops, commodi-
ties and services, rather than disciplines, and will
provide a guide for program direction which has not
previously been possible.

The entire research program of the Florida Agricultur-
al Experiment Stations is planned and conducted by use of
formal written and approved projects which document all
research. The research program is primarily a mission-
oriented effort aimed at solving the problems of agricul-
ture. As problems arise new projects are initiated. When
problems are solved, projects are terminated. At the
present time there is a continuing trend toward greater
team effort than in the past. Problems are more difficult
and require the interdisciplinary approach for best
results. As new problems arise and new projects are
planned, they are carefully screened and reviewed before
activation. Maximum coordination now is achieved by close
working relations within the entire system of campus
departments and research centers located throughout the
state.









The current research is reported to the public in many
ways, primarily through published articles, bulletins and
books. In addition, much research is reported at con-
ferences and meetings. Within the organization many tield
days, short courses and conferences are held to which the
public is invited. These are held throughout the year by
departments, and at research centers throughout the state.

A brief report is included here of all projects on
which research was performed in 1974. Projects reported
here are arranged ty departments and centers. The reader
is referred to the index in order to obtain complete and
detailed iniormaticn on a given question, topic, commodity
or process.

We hope you will find this report informative and
useful.

The Center for Environmental Programs in the Institute
of Food and Agricultural Sciences was formed in October of
1973 to bring focus and impetus to a highly relevant
problem area. The establishment of the Center followed two
years of preliminary work, redirection of existing
resources and a $500,000 appropriation from the state
legislature to expand environmental programs. The Center
for Environmental Programs has statewide responsibilities
for IFAS programs dealing with environmental problems. The
Center's main research thrusts are: non-chemical pest
control; abatement of pollution from agricultural runoff;
biological control of aquatic weeds; assessment and manage-
ment of ecosystem resources for maximum benefit to society;
abatement of pollution from agricultural drainage from
organic soils; reduction of risks to agricultural workers
re-entering groves or fields sprayed with pesticides;
reduction of non-point sources of pollution from livestock
and agricultural chemicals; the utilization and disposal of
animal wastes; the utilization and disposal of municipal
sewage effluent and digested sludge in agricultural sys-
tems; assessment of the impact of environmental restraints
upon agricultural production technology; a systematic ana-
lysis of the impact of environmental quality restraints
upon agricultural production; and the impact of research
upon environmental quality.

Both state and grant funds are used in support of the
Center programs. All research is conducted under regular
research projects and is reported by the various units.
Faculty supported by the Center are located in the appro-
priate discipline or commodity department or at the various
Agricultural Research and Education Centers. Funds from
the Center were used to initiate and support ongoing
research in eight departments and nine off-campus units.
The main goals of the Center are to: 1) minimize the
adverse effects of agricultural production technology on
the environment; 2) utilize the unique features of agricul-
tural science and technology to provide alternate solutions
to urban environmental problems, e.g. recycling municipal
secondarily treated effluent and digested sludge in the
agricultural soil-plant system; and 3) minimize the adverse
effects of non-agricultural pollutants upon agricultural
production.

The funds which supported research from the Center
have been used in part in research that has demonstrated
that a half gallon of a plastic water repellent sprayed on
the surface of the ground not only reduced nutrient
leaching from fertilizers used to produce corn, but also
increased the yield from 38 to 100 bushels per acre. A new
technique for making citrus concentrate reduces thermal
water pollution by eliminating the boiler--cutting the







energy use 25-40%. Both private industry and Center
support were used in this research. ways tp manage
pollution from non-point sources, diffuse materials, i.e.
fertilizer nutrients, pastured livestock or applied pesti-
cides, are being investigated. Production systems for
vegetables, ornamentals and cut flowers are being developed
which minimize the use and losses from agricultural chemi-
cals used in production as well as conserve water. The
Mirex fire ant eradication program was evaluated on a
systematic basis to-determine its effectiveness and cost/
benefit ratios. Preliminary information indicates a nega-
tive cost/benefit ratio. Plant nutrient losses from tile
drains, animal wastes, including those from urban pleasure
horses, wildlife .management, new techniques for pesticide
measurement, diseases of mangroves, the chemical breakdown
or organic soils, recycling drainage water from organic
soils, eliminating the need for pesticide sprays in citrus,
and wildlife disease research constitute the major parts of
the program.






CENTER FOB RURAL DBVELOPKENT


Rural Development research programs were expanded with
the provision of additional faculty positions and increased
support to existing faculty in eight departments and two
off-campus Agricultural Research Centers. These research
efforts have been largely concentrated on problems of the
North Central Florida Region and are directed to the
following program thrusts.

The first general program thrust is that of developing
production and marketing technology for small-scale,
limited-resource farmers. Production and marketing feasi-
bility information for vegetables, ornamental crops, deci-
duous fruits and nuts, agronomic crops and small-scale
livestock enterprises was initiated through a number of
research projects. Production technology including ferti-
lity, variety adaptation, irrigation, planting systems,
cultural practices, etc., based upon production conditions,
soil and climatic conditions of the region was researched
for a number of vegetables, woody ornamentals, pecans and
peanuts, both on experimental plots and on field experi-
ments in cooperation with existing producers in the region.
A small-scale, portable feeder pig production system was
designed and put into practice at the Live Oak Agricultural
Research Center.

Market research was initiated to determine market
feasibility conditions for vegetables and woody ornamentals
produced (or capable of being produced) on small farms in
the region. This research is investigating which markets
(principal cities, towns, rural areas), which marketing
outlets (roadside, curbside, farmers' markets, contract
growers, local brokers, cooperatives, etc.), and what mix
of products for vegetables and for the woody ornamentals
are most appropriate to serve small-scale producers in the
region. Detailed recommendations regarding quality needs
and quantities demanded at times and prices competitive
with present supplies, and "best" marketing strategies and
services needed will be developed from this information.

Additional research on the goals and objectives of
small farmers and their families, the diffusion and adop-
tion of new enterprises and new technology (including the
cultural, social and communal factors which influence the
process of acceptance of new agricultural enterprises) was
initiated. The research information being developed will
be used for planning production systems for small-scale
farming units sufficient to reach target levels of farm
operator and family net incomes or other objectives under
conditions of full-time farming, part-retirement farming,
and part-time farming coupled with either part-time or
full-time off-farm employment, and consistent with the







resources (acreage, soils capital, labor, management
levels, etc.) on these farms.

A second general program thrust, directed toward
another set of problems that exist for these rural people
as well as others in rural communities, is that of
substandard housing units. Research was initiated t3
determine alternatives to present forms of construction and
marketing of rural housing units for families with low-to-
moderate incomes. The research is investigating the moti-
vations, expectations, attitudes and financing ability of
these rural families relative to their housing situation.
Design and cost evaluation of various types of housing
units that meet with the income level of families and their
ability to pay for improved housing was begun. Construc-
tion of demonstration housing units at a University of
Florida operated medical clinic in the region has been
planned to acquaint families with the types of housing
units available to them.

A third research program thrust addressed itself to
the food habits, food acquisition methods and nutritional
status of the rural poor and the aged in the region.
Research was initiated to determine the nutritional compo-
sition.of these persons' diets, the nutritional value of
locally produced foods and purchased foodstuffs and the
nutritional needs and/or requirements of persons residing
in the region scaled according to age, sex, occupation,
health status, etc. The major research thrust is the
development information on low-cost menus or diets based
upon nutritional needs, availability of alternative foods,
a range of food costs, and consumer's food budgets. Such
information will ne used to develop nutrition education
programs for the target clientele as well as for practicing
physicians in the region and elsewhere in the State.

A final program thrust involved research to determine
alternatives for providing public services and facilities
to rural people and the associated land use requirements.
The research involved the general description and charac-
terization of land areas according to their agricultural
and nonagricultural use potentials; the examination of
alternative arrangements and costs of financing and produc-
ing certain public services (municipal waste disposal,
solid waste disposal, water systems and other public
service facilities); and the associated land use changes
required to meet these public service needs.

Comprehensive planning for public facilities and land
use in rural areas and communities is the major research
thrust. Information on the wide range of development
alternatives that are available to the region is required.
Private (individual) and social trade-offs among agricul-
tural and nonagricultural uses of rural land and other
resources must be identified. The incidence of private








versus social benefits and costs are being evaluated in
order to provide information to decision makers in the
region on alternatives for allocating scarce community
resources.








IUTERkATIONALQL QGjOA


All activities which build or strengthen the interna-
tional dimension of IFAS are administered by the Office of
International Programs. Major activities include adminis-
tration of contract and grant technical assistance, train-
ing of foreign nationals and supporting research in tropic-
al agriculture.

The Center for Tropical Agriculture, as a major
component of the Office of International Programs, assists
with policy determination and is responsible for coordina-
tion within IFAS of tropically-oriented research and ser-
vice projects. It provides research and travel grants to
faculty and graduate students, assists academic departments
in curricula development, supports development of library
and laboratory facilities and publishes and disseminates
results of tropical research.

International Programs serves as a liaison office for
IFAS with the Florida Department of Agriculture and agribu-
siness in carrying out international activities that com-
plement State programs. Projects administered by Interna-
tional Programs develop technology applicable to Florida,
attract agriculturally-oriented industry to the State, open
agribusiness investment opportunities for Florida private
enterprise and expand markets for Florida's gpods and
services.

IFAS is increasingly being called on to advise in the
production, marketing and processing of agricultural pro-
ducts in the tropics. Participating in international
research programs strengthens expertise in these areas. In
solving many of the problems it is beneficial to use an
interdepartmental approach. For example, in carrying out
research on tropical and subtropical livestock production
and pasture improvement, scientists from Animal Science,
Agronomy, Food and Resource Economics, Soils and the
Veterinary Science Departments are cooperating. It is
anticipated that much of the tropical research in the
future will require a multidisciplinary approach. IFAS,
through its office of International Programs, is well
prepared to accept this challenge.

Research training and technical assistance were pro-
vided through nine contracts and four grants during 1974.
Staff from almost all units of the Institute participated
in some phase of these activities.

The two contracts with the Agency for International
Development involving technical assistance for educational
institution building in El Salvador and Vietnam were
continued. The grant received in 1973 from the Institu-
tional Grants Program of the Agency for International









Development continued to provide funds to strengthen the
capabilities of the University in ruminant livestock deve-
lopment in the tropics.

Other continuing projects included a small contract
with the Central Bank of Nicaragua for technical assistance
on tropical crops and beef cattle production, the livestock
production and agricultural economics research programs in
Ecuador under loans from the World Bank and Inter-American
Development Bank to the Government of Ecuador and the
development of a food technology laboratory at the Univer-
sity of Costa Rica under a contract with the Missipn office
of the Agency for International Development in San Jose.

New contracts and grants received included a contract
for mineral research in Latin America, growing out of the
work done while developing the feed composition tables for
South and Central America. This contract is through the
Technical Assistance Bureau of the Agency for International
Development. Two small, one year grants were received from
the Rockefeller Foundation to promote the development of an
international peanut program and for southern pea cowpeaa)
research. Dr. D. E. Eccloud, former Chairmhn of the
Agronomy Department, is the principle investigator under
the peanut program and is working on the development of a
germplasm center. Dr. L. C. Hannah of the vegetable
Crops Department will be heading the research on protein
improvement of the southern pea or cowpea. Additional
funds will be received from the Rockefeller Foundation and
the Food and Agriculture Organization of the United Nations
to fund an International workshop on Peanut Production at
the University of Florida during the summer of 1975.

A small contract for short-term technical assistance
on swine production was signed with the Livestock Division
of the Banco Nacional de Foaento in Tequcigalpa, Honduras
on September 5, 1974.

The research program for development of livestock and
pasture projects in Brazil under a contract with the
Government of Brazil was continued.

Funds were provided for Dr. William Zettler of the
Plant Pathology Department to study cocoyam virus diseases
and to evaluate resistance in the edible forms. The grant
came through the efforts of the Center in acquiring funds
from the USDA-ARS allocation for tropical agricultural
cooperative research.

The Office of International Programs continues to
promote research on new horticultural varieties, plant
pests and diseases and nutritional studies of livestock
production in the tropics, feeling that increasingly in the
future the development of agriculture in the tropics and
subtropics will be of direct benefit to Florida in terms of






expanded markets for our commodities and for joint research
on pests and diseases that pose problems for future
development both in subtropical Florida and Latin America.

AGHICULTJHAL ENGjNEERING DEPARTMENT


Research was conducted under fourteen projects and
nonprojected preliminary research was conducted in seven
areas. New research was begun on the use of solar energy
in agricultural systems, pollution in runoff from nonpoint
sources, the etfect of shade on dairy cows, energy conser-
vation in heating/cooling buildings and drip irrigation for
fruit and vegetable crops.

A construction project in Frazier Rogers Hall to
greatly expand laboratory facilities and add four faculty
offices was begun during the year. Five modern labora-
tories for conducting research on soil and water engineer-
ing, processing of agricultural crops, physical properties
of agricultural products, agricultural structures and
environment, and agricultural machinery are included in the
approximately 5,000 square feet addition. Construction is
about 70 percent completed and occupation is expected in
March of 1975.

Dr. E. T. Smerdon resigned as chairman of the
Department in January 1974 and Mr. Rush E. Choate served
as acting chairman for the remainder of the year. Dr.
Gerald L. Zachariah will report as the new chairman on
February 1, 1975. No other major faculty changes were made
during the year.

PRELIMINARY AGRICULTURAL ENGINEERING RESEARCH

PROGRESS REPORT: 74/01 74/12
A gladiolus corm drying study indicates lower flower
quality and corm production results from overdrying. A
field plot experiment is underway to develop design cri-
teria for drip irrigation systems for citrus. Sites have
been, selected for a study of non point source of entry of
nutrients into runoff water from lands used for agricultur-
al production. Subsurface drainage studies at Hastings
indicated much more rapid lowering of the water table after
heavy rains with drain tubing than by the conventional
furrow method. The water table was maintained satisfac-
torily at the desired level during dry periods by subirri-
gation through the tile drain lines. Development of a
generalized psychrometric sensor is continuing. If succes-
sful, it will allow measurement and control of any
temperature-humidity variable identifiable as a line on the
psychrometric chart. A greenhouse at Bradenton has been
equipped with a solar heating system which collects heat
during daylight, stores it in water in a 2000 gallon tank.
The hot water is then circulated through forced air
convectors when heat is required. The efficiencies of








solar collectors (water and air) constructed from various
materials have been determined. A hot soil holding bin has
been developed for the continuous, direct heat soil pas-
teurizer. A hydraulic stake driver for flower growers has
been developed.

STRAWBERRY CULTURE

PROGRESS REPORT: 74/01 74/12
A strawberry production experiment was conducted to inves-
tigate drip irrigation as a means of increasing production,
and reducing irrigation water and fertilizer requirements.
Production was about the same for drip and sprinkler
irrigation with an irrigation plan in which water was
supplied by drip irrigation in the amount equal to 50
percent of the water required for sprinkler irrigation.
When the quantity of water applied by the drip method was
reduced to 30 percent of the sprinkler requirement, yield
was reduced by about 5 percent. Excellent response was
obtained by applying part of the fertilizer through the
drip irrigation system. Production was increased by 9
percent, with 30 percent less fertilizer, if 50 percent of
the fertilizer was distributed along with water through the
drip irrigation system rather than being applied in the bed
prior to planting. Highest yields were obtained from the
highest level of fertilization (120 lbs N 160 Ibs
P(2)0(5) 160 nos K(2)0 per acre), with 50 percent of the
fertilizer applied with irrigation water through the drip
system and with a water quantity equal to one half the
normal sprinkler irrigation requirement. The best irriga-
tion treatment produced 21 percent greater yield than the
sprinkler irrigation treatment and 73 percent more than the
unirrigated check.

SYSTEMS FOR TILE DRAIN SLUDGE CONTROL FOR CITRUS WITH HIGH
WATER TABLE IN FLORIDA








PROGRESS REPORT: 74/01 74/12
Hydraulic gradients in a 5-cm interval across the gravel
envelope-soil interface of drains in the deep-mixed treat-
ments are considerably higher than predicted by resistance
analog models indicating that the restriction to flow is at
the interface. Water table elevation-drain outflow rela-
tionships have not changed during the four years of
measurement indicating that any restrictions to flow dave-
loped during the 6 month period between drain installation
and beginning of measurements. Calculations were made of
water pressure distribution in Oldsmar soil which indicated
poor transport upward from the water table. Corrugated
plastic drains installed in a potato field have performed
very satisfactorily for both drainage and subsurface
irrigation.

PROCESSED AQUATIC PLANTS FOR ANIMAL NUTRITION

PROGRESS REPORT: 74/01 74/12
In order to develop a system for producing cattle feed from
waterhyacinths, harvesting and processing equipment and
procedures have been designed and tested. Major accompli-
shment was completion and preliminary testing of a floating
crimper-harvester; 6-foot wide, 8-inch diameter crimping
rolls, with axes in a plane 45 degrees from vertical,
rotate at 400-600 rpm just above the water surface,
grasping the plants, breaking the stems and throwing them
into a holding area. A small lifting roll just below and
ahead of the lower crimping roll, and a 12-inch upper roll
improve performance. Whole, chopped and pressed waterhya-
cinths have been dried on direct-insolation convection-
transfer solar dryers to determine feasability of the dryer
concept and its use to eliminate the excessive fuel
requirement for drying.

CHARACTERIZATION OF RHEOLOGICAL PROPERTIES 3F FRUITS AND
VEGETABLES

PROGRESS REPORT: 74/01 74/12
Breakage of green beans during harvest and handling consti-
tutes a major loss. Investigations of the nature of
breakage under impact conditions and of the variables which
influence it should enable loss reductions. Preliminary
green bean breakage tests under impact indicate approxim-
ately 0.1 joule (0.08 ft Ib) energy required for breakage
of half of beans tested when impacted on flat side at 100
cm/sec (39 in/sec). All beans broke under more severe
testing conditions (twice as much energy available for
breakage); Miami required the same maximum force for








breakage with impact on side or on dorsal suture, and
Sprite required less force for breakage when impact was on
side than on dorsal suture. A digital transient recorder
has been used to expand the time scale of force versus time
curves of impact to allow their double integration on an
analog computer, obtaining velocity and deformation curves
for more complete analysis of the impact phenomena.

FORCED AIR PRECOOLING OF FLORIDA VEGETABLES

PROGRESS REPORT: 74/01 74/12
Cooling of fresh vegetables promptly after harvest is a
method of maintaining product quality by limiting the
deteriorating processes aided by warm temperatures. The
operation is essential for most Florida vegetables and has
been practiced for many years using various means of
removing heat. Although hydrocooling and vacuum cooling
have been used predominately in the vegetable industry,
forced air cooling promises to be superior for many
products and has the potential of being more universally
applicable. Cooling tests are being conducted on various
products in a research facility designed specifically for
determining and evaluating design parameters for forced-air
precooling systems. The data collected for each test
includes; air velocity, air temperature, relative humidity,
temperature distribution within the individual product and
within the bulk load, static pressure loss through the
product, and product moisture loss during cooling. Data
from the" precooling experiments are recorded using a
digital data acquisition system. Output from thermo-
couples, air-flow meter, humidity, indicator, etc. may be
printed on paper tape or recorded on magnetic tape and
processed through a digital computer to obtain the desired
plot of the cooling data. Cooling tests have been con-
ducted on bulk loads of oranges, grapefruit, snap-beans,
bell peppers and avocados. Preliminary tests with the
product in cartons have been run on avocados, oranges, and
grapefruit. Using basic heat transfer theory, a mathemat-
ical model describing the temperature distribution within a
bulk load of fruits or vegetables has been developed and
tested for oranges and grapefruit. This model is being
modified to accommodate irregularly-shaped and nonhomo-
geneous products.

FERTILIZERS AND ORGANIC WASTES APPLIED TO SOILS IN RELATION
TO ENVIRONMENTAL QUALITY

PROGRESS REPORT: 74/01 74/12
Nutrient transport in sandy soils was analyzed by the








theory of convective diffusion. Processes of convection,
diffusion, adsorption, and reaction were included. At low
flow velocities the dispersion coefficient was identical to
the diffusion coefficient. Phosphorus transport in Lake-
land fine sand was found to be dominated by chemical
kinetics and convection under flowing condition.

ECONOMIC, BIOLOGICAL AND ENVIRONMENTAL ASPECTS OF DAIRY-
BEEF CROSSES ON PASTURE AND IN DRYLOT

PROGRESS REPORT: 74/01 74/12
Investigation of the environmental impact of pasture,
semi-confinement, and complete confinement cow-calf produc-
tion is continuing. In the pasture phase, two sites have
been selected for measurement of the quantity and quality
of surface runoff and groundwater. One site is improved
flatwoods pasture with 1.33 acres per cow-calf unit and the
other site is in similar topography but with natural forest
cover and no cattle. Groundwater samples are being
collected from soil solution samplers at 1, 2, 3, 4, and 5
ft. depths and from 10 and 20 foot deep wells. H-flumes
and automatic samplers are being installed to measure the
volume and quality of surface runoff from both sites. In
the semi-confinement phase, the facility has been con-
structed and feeder calves have been placed in the
facility.Groundwater samples are being collected within the
facility and in the surrounding area. The lagoon for the
confinement unit has been constructed and a system of 3h
groundwater sampling tubes and wells has been installed
around the lagoon to monitor groundwater flow and quality.
Construction of the confinement facility is scheduled for
early 1975.

RENOVATION OF MUNICIPAL WASTE WATER AT TALLAHASSEE

PROGRESS REPORT: 74/01 74/12
Forage crops were irrigated with secondary effluent. Wint-
er crops were rye and ryegrass. Summer crops were coastal
bermudagrass, pearl millet, and corn. Crop uptake of
nutrients increased with irrigation rate, while efficiency
of nutrient recovery decreased. Yields under effluent
irrigation compared well with those under normal agricul-
tural practice.

ANIMAL WASTE TREATMENT AND RECYCLING SYSTEMS

PROGRESS REPORT: 74/01 74/12
Sludge characteristics and accumulation rates were estab-
lished for an anaerobic dairy waste lagoon. Sludge accumu-
lated at a rate of 14.9 to 16.9 percent of lagoon volume
per year, or 0.003d cu m per kg of volatile solids added.
These results indicate that sludge removal may be required
at 5 year intervals. Total solids content of the sludge
averaged 6.3 percent after 4.67 years. Volatile solids
content was 58.8% of total solids. Nitrogen levels in the
sludge were quite high, averaging 3030 mg/1 of total
nitrogen and 1,020 mg/1 of ammonium nitrogen. pH tended to
decrease as depth increased and to increase slightly as
distance from the inlet increased in the lagoon. Tempera-
ture profiles measured in the lagoon indicated no diurnal
temperature stratification occurred. A system for batch
aeration and pasteurization of swine wastes for refeeding
was successfully tested. Additional work on a feeder for
recycled waste is planned. Work was initiated on an
evaluation of the feasibility of collecting bio-gas from
existing anaerobic lagoons.

MAXIMIZING EFFICIENCY OF FERTILIZER AND WATER USE F3H
VEGETABLES

PROGRESS REPORT: 74/01 74/12
Tomatoes were grown in an experiment in the spring of 1973
and 1974 to measure the influence of method of irrigation,
mulching, and field seeding method and fertilizer rate.
Drip and sprinkler irrigation methods were tested. During
the relatively dry 1973 season yields were increased over
unirrigated plots 290 percent with sprinkler and 380
percent with drip irrigation when part of the fertilizer
was applied through the drip irrigation system. During the
wetter 1974 season, the influence of irrigation method on
yield was small; however, best results were obtained with
drip irrigation plus fertilizer applied through the drip
system. Mulching provided a significant yield increase
over unmulched plots. Also, yields from "plug-mix" seeded
plots were greater than from conventional seeding. Drip
irrigation provides a method of efficiently applying water
under the mulch. The assurance of a satisfactory soil








moisture condition under the mulch greatly increases the
probability of seedling emergence and survival in a field
seeding situation. One of the major problems encountered
with mulch for tomatoes, salt accumulation around the
seedling, should be eliminated by the use of drip irriga-
tion. Salt concentration in soil at the center of the bed
near the surface was approximately 1300 ppm for the drip
irrigation plus fertilization treatment, 2600 ppm for
sprinkler irrigation and 3720 for unirrigated.

SIMULATION MODELS OF THE TRANSIENT ENERGY REQUIREMENTS TO
HEAT/COOL RESIDENTIAL BUILDINGS

PROGRESS REPORT: 74/09 74/12
Digital computer models are being developed to stimulate
the transient energy requirements to heat/cool residential
buildings. The models also have the capability to be
applied to buildings without heating/air conditioning sys-
tems; then the models predict the transient inside air
temperature. The models are able to document the effect on
energy requirements of residential buildings by: altering
construction materials, changing outside and inside air
temperatures; shading portions of the building, ra3f
sprinkling, changing infiltration and ventilation rates,
etc.








AGRONOMY DEPARTMENT



Research was conducted on agronomic crops under 28
projects during 1974. Some significant findings in 1974
were as follows:

Fourteen new experimental corn lines crossed with two
inbred testers produced hybrids which had improved standa-
bility and resistance to rice weevil infestation. Aboat
100 of 200 new lines of corn have shown resistance to
stalk-rotting organisms.

An improved computerized simulation growth and develo-
pment model was developed for peanuts. A study revealed
that farmers with small peanut acreages do utilize the
latest technology.

Herbicide programs were developed for weed control in
corn, peanuts, soybeans and tobacco. Sicklepod was deter-
mined to be the most important weed in soybean fields.

Two new White Clover synthetics showed greater persis-
tance, demonstrated and produced a larger number of stolons
than 13 varieties grown in comparison.

Kinderlou, a new annual ryegrass, reseeded better on
common bermudagrass pasture than did Gulf, Magnolia and
Florida Bust Resistant ryegrasses. A mass selection pro-
gram to develop a more leaf-rust resistance reygrass is
underway.

Selections of rhodesgrass (Chlogis a saAa) from Africa
were identified which demonstrated an ability to grow at
reduce day lengths in north Florida.

The peanut variety, Florunner, developed in Florida
was planted on 90% of the total peanut acreage in the
Southeast in 1974. A new early maturing Virginia bunch
peanut selection developed from a cross of two Florida
breeding lines is scheduled for release in 1975.

Soybean breeding lines resistant to two commonly
occurring nematodes were selected. Soybean introductions
from India were used in 1974 to develop varieties with
higher protein content.

Total mechanization of tobacco culture was further
perfected with the use of direct field seeding of tobacco
seeds on tapes.

An abscission agent for use in harvesting citrus has
continued to perform very satisfactorily. Commercial deve-
lopment is anticipated for 1975 or 1976.








A new tobacco sucker control agent developed in the
Agronomy Department was shown to function well at a rate 10
times lower than the leading sucker control agent.


Grazing studies with beef animals showed that the
tropical legume (_Desodiin i2_ortu) requires a rest period
of 28 days between grazing to maintain stands.

Acreage of twelve tropical grasses was established to
evaluate their feeding value at five growth stages.

Nitrogen fixation by 'Transvala' digitqrass under
field conditions was obtained following inoculation with
the nitrogen fixing bacterium, REirillum lipofgrum.

Grain yields of corn were increased by 44% using
programmed applications of nitrogen and potassium as com-
pared to corn fertilized with the same rates in convention-
al programs.

NOS-PROJECTED AGRONOMIC RESEARCH

PROGRESS REPORT: 74/01 74/12
A computerized simulation growth and development model of
the peanut (PENUTZ) was developed using data from the 1973
growth analysis study for calibration. Further validation
is continuing using field experiments and the 1974 growth
analysis. The growth analysis study was conducted in 1974
at three plant populations: 8.6, 11.9, and 13.5 plants/ma
in high yielding peanuts. The drymatter partitions of
roots, stems, leaves, and peanuts was followed weekly from
seeding to maturity. The total drymatter produced for the
low, medium, and high plant populations was: 11,041,
9,129, and 11,371 kg/ha. The yield of peanuts was: 5,879,
4,860, and 6,388 kg/ha for the three populations. A
shade-stress field experiment showed that the most marked
peanut yield reduction resulted from shade-stress applied
during the flowering period, when most of the photosynthate
was being utilized for fruit A drought-stress greenhouse
experiment produced similar results. In a peanut spacing
study with a concentric circle planting pattern, Florunner
compensated and produced high yields, 3,942 kg/ha, over a
range of spacings from 20-30 cm, but UF 70115 produced
maximum yields of 5,954 kg/ha at a 22 cm spacing and showed
consistent yield reductions with increased spacing. A
study comparing small and large farmer peanut growers
sampling 42% of the Florida peanut acreage showed that
small farmers had both the highest and the lowest peanut
yields, and large farmers tended to produce above average
peanut yields. The study showed that small grpwers do
utilize the latest technology.

WHITE CLOVER AND ALFALFA BREEDING

PROGRESS REPORT: 74/01 74/12
White Clover Selected clones representing material having
good summer persistence, vigor, and plant type were planted
in a polycross nursery. Seed were collected from each
plant to use in a progeny test to evaluate general
combining ability. Considerable variability was observed
among the various entries in plant type, flowering, and
other characters. Thirteen established varieties and two
Florida synthetics, FS-4 and FS-5, were compared in a
variety test. The highest yields were exhibited by FS-4,
Regal, FS-5, Merit, and Tillman, while those having the
lowest yields were La. S-1, Nolin's Improved, Kent, and
Minn A. FS-4 and FS-5 had the highest stolen count in
mid-summer. Intensive studies of HCN production showed
that La. S-1 and Nolin's Improved had the highest levels
of the 15 lines in the variety test. Samples taken from
clover populations in the general area revealed many with
high HCN levels. Continuing studies comparing "viney" and
"bunch" type plants showed that populations of "bunch"
plants, produced 70% more total forage than did "viney"
plants. Alfalfa Spotted alfalfa aphid resistance is
essential to successful seed production in the western
states. Dr. V.V. Nielson, USDA entomologist in Arizona,
was successful in isolating 32 resistant plants from
Florida 66 alfalfa. These plants have been shipped to
Gainesville and are being intercrossed during the winter of
1974-75.

EVALUATION OF INTRODUCED AND NATIVE PLANT SPECIES FOR
PASTURE, FORAGE AND OTHER USES

PROGRESS REPORT: 74/01 74/12
Kinderlou ryegrass reseeded better on a common bermudagrass
pasture than Gulf, Magnolia, and Florida Rust Resistant
ryegrasses. Close grazing of the bermudagrass during the
fall favored the reseeding of the ryegrass. Mass selection
was initiated to develop a rust resistant, reseeding
ryegrass variety. Over 7,000 plants collected from pas-
tures where ryegrass had reseeded for two or more seasons
were transplanted in a spaced plant nursery. Approximately
1/3 of these spaced plants were destroyed before flowering
because of poor growth or high rust susceptibility. The
nursery was divided into 18 plant units and the best plant
selected in each unit. Equal quantities of seed from each
selected plant were mixed to make a composite seed sample
for yield tests and nursery spaced plants for further
reseeding, rust resistance and vigor selections.
