INTRODUCTION
This bibliography was prepared for distribution and exchange with other
forage crops researchers. The following brief introduction provides an
insight into the general history, environment, and pasture species of the
area.
The subtropical south Florida region is located south of an imaginary
semicircular line between latitude 28 and 290N with an average rainfall of
about 1300 to 1600 mm annually (Butson and Prine, 1968). It includes about 24
of the 67 counties in the State.
At least one tropical forage species adapted in south Florida is listed
in each of the climatically delineated regions presented by Reid (1973).
Almost all legumes and grasses listed by Russell and Webb (1976) as being
commercially used in the tropics and subtropics have been grown successfully
at the Agricultural Research and Education Center, Ft. Pierce (ARECFP). Thus
research results obtained from south Florida locations may be adaptable to
other subtropical and tropical areas of the world.
The livestock industry in Florida had its beginning in 1520, when Ponce
de Leon brought the first cattle from Cuba (Cunha, 1976: Kirk and Peacock,
1959). But high water tables, low soil fertility, poor transportation
facilities, and inaccessibility of markets prevented rapid development of the
industry in south Florida until the present century. In 1929 there were about
355,00 head of cattle in Florida. According to the 1987 USDA inventory, there
were about 1.9 million beef cattle in the state.
It was not until the 1930's that the "salt sick" (nutritional anemia)
cattle problem was solved through proper mineral nutrition. The deficient
elements included Ca, P, Cu, and Co. On the majority of soils now used for
cattle production in south Florida it was not unusual to have calf crops of
30-35Z (Becker and Henderson, 1940). Mott and Moore (1977) reviewed the
history and recent day techniques of finishing cattle on forage or on limited
feed in Florida.
Until the 1940's, a large majority of the pastures consisted of native
grass species which included maidencane (Panicum Hemitomon Schultes), creeping
luestem (Andropogon stolonifer (Nash) Hitch.), and chalky bluestem
(Andropogon capillipes Nash). These desirable species were slowly replaced by
pineland threeawn (Aristida strict Michx.), smutgrass (Sporobolus poiretii
Hitchc), and others. Encroachment of undesirable shrubs such as saw palmetto
(Serenoa repens (Bartr.) Small), wax myrtle (Myrica cerifera L.), and
gallberry (Ilex glabra (L.) Gray) also decreased carrying capacities (Ruelke
and Killinger, 1976). The stocking rate on native south Florida pastures is
about 1 animal unit per 15 to 20 acres.
Research on introduced improved pasture species in Florida began in 1892
(Jones, 1969) and the 1893 fertilization recommendation was to use 400 to 800
Ib/A of a 6-6-8 (N-P20O-K0O) fertilizer. This recommendation was not changed
and did not markedly u'htl the mid 1950's (Hodges and McCaleb, 1959), when
higher analysis fertilizers came into use.
The first successful forage introduction was natalgrass (Rhynchelytrum
roseum (Nees) Stapf. & C.E. Hubb.) and the first reported legume to be used as
velvetbean (Mucuna pruriens (L.) CD. var. utilis (Wall) Burck. (McCloud,
1953). Introductions of other grasses, i.e. paragrass (Brachiaria mutica
(Forsk.) Stapf.) (1910), bahiagrass (Paspalum notatum Flugge) (1913),
centipedegrass (Eremochloa ophiuroides (Munro) Hackel) (1919), and legumes
Crotolaria mucrunata Desv. (1909), alyce clover (Alysicarpus vaginalis (L.)
DC.) (1924), and hairy indigo (Indigofera hirsuta L.) (1931) helped in the
development of better pastures. These efforts generally were related to the
cattle industry in north Florida.
Recognition of the benefits of liming (Killinger, 1957) and fertil-
ization (Gammon et al., 1959), helped in the establishment and use of newer
introductions of grasses, particularly pangola digitgrass (Digitaria decumbens
Stent.) (Hodges et al., 1967) and legumes, particularly white clover
(Trifolium repens L.) (Blaser and Boyd, 1940; Kretschmer, 1962) in south








Florida. During the 1960's, the two tropical or warm-season introduced
legumes having some success for grazing were hairy indigo (Wallace, 1957) and
alyce clover (Blaser et al., 1942). Creeping beggar weed (Desmodium canum
(J.F. Gmel.) Schintz & Thell.), a native legume, is an invader in many
pastures (Roush, 1974).
The mineral soils of subtropical Florida are dominated by Spodosols and
Entisols. With the exception of marl soils found in the extreme southern part
of the State, and the organic soils (Histosols) south of Lake Okeechobee, the
soils are acid, infertile, and sandy in texture. They fall within the hyper-
thermic zone. The soil parent material consists of various marine sediments.
Although quartz sand is the predominant, and often the only mineral present in
the surface horizons, clays, shell and marl may be found at depth in some soil
types. However, when present at all, these materials are generally well below
the root zone of forage grasses and legumes. As compared to many other soils
in the hyperthermic zone, south Florida soils are very low in Fe and Al
sesquioxides. Neutral IN KC1 exchangeable Al is often less than 1 meq/100g
(Fiskell and Zelazny, 1972).
Cation exchange capacity (CEC) is low and predominantly pH-dependent,
since it results almost entirely from organic matter (OM). Surface horizon OM
may be very low in the Entisols, and is quite variable in the Spodosols
(Calhoun and Carlisle, 1974). The Spodosols are often intermingled with
Entisols and even with small pockets of Histosols, giving the landscape a
pockmarked appearance from the air. This association is known locally as the
flatwoods" soils. The influence of these soil associations on plant growth
is often very apparent long after the land has been cleared and placed under
cultivation. Over short distances there can be drastic changes in certain
soil properties, such as OM content and CEC. Therefore, it is almost
impossible to manage large areas in a manner that is optimum for all soil
conditions present. For example, following lime application of 400 lb/A to
plots within a 40 by 230 ft area of Myaka fine sand (Spodosol), pH's among the
plots ranged from 5.1 to 6.5. Soil pH was negatively correlated with OM
content which ranged from 0.2 to 2.3Z within the 0.2 acre area (Gascho et al.,
1973).
The Entisols found on the ridge area of the central part of the state
are often well or excessively well drained, but both the Entisols and
Spodosols of the flatwoods regions are predominantly poorly drained. Poor
drainage results primarily from the low, level topography. In addition, the
Spodosols are characterized by a water restricting B2h horizon, up to 3 ft in
depth.
A typical profile of a Florida Spodosol as synthesized from statistical
data on 34 pedons (Calhoun and Carlisle, 1974) is:

In their native state the flatwoods are periodically flooded or waterlogged
during the wet season. Some drainage is provided for pasture lands, but water
tables are nevertheless often quite high.
In south Florida, because of the fluctuating length and intensity of cold
temperatures in the winter and normal lack of effective soil moisture from February
to May or June, it is difficult to estimate the annual optimum stocking rate.
Stocking rates of the predominantly cow-calf beef system used in south Florida are
a compromise between overabundance of pasture during summer and paucity during








winter and spring. It appears that although minor changes may be made by growing
specialized forages to overcome the lack of winter feed, only the use of high-
quality stored hay or silage may solve the cyclic problem in an economic manner to
permit similar year-round stocking rates.
Clipping tests have shown that winter growing clovers and ryegrass can
contribute up to 2.5 to 3 tons of dry matter/A in the winter and spring period
(Kretschmer, 1966; Kretschmer 1978). But both require adequate rainfall or
irrigation in the spring. Because of this and the difficulty of maintaining an
adequate water table for seep irrigation, emphasis on developing and using temp-
erate species for winter growth has decreased.
Agronomic work at the ARECFP (270 25'N, 800 24'W) formally began in 1955.
Monthly rainfall averages and percent rainfall per month of yearly rainfall for a
28 year period at the ARECFP are as follows:

Areas to the north and west of the ARECFP are cooler in the winter and
somewhat warmer in the summer. All except the extreme southern portion of the
region is subjected to several frosts during the December-March period, with severe
freezes (-40 to -60C) occurring occasionally, particularly in the northern part.
Although grass growth rate is restricted during the cool season, growth can be
extended, through judicious use of fertilizer and water control, and particularly
through the use of several grasses such as Bigalta and Floralta limpograsses
(Hemarthria altissima Stapf & C. E. Hubb.), the stargrasses (Cnodon nlemfuensis
Vanderyst.), and Taiwan digitgrass (Digitaria pentzii Stent.). These grasses grow
more rapidly in the cool season (but at present are planted in relatively small
areas) than do Pangola digitgrass (Digitaria decumbens Stent.) and the bahiagrasses
(Paspalum notatum Flugge). High quality temporary pasture of annual ryegrass,
oats, red and berseem clovers, and alfalfa have been used for winter-spring grazing
in special circumstances, when irrigation is available. 'Louisiana S-1' and
'Nolins Improved' white clovers (Trifolium repens L.) which commence flowering in
late February and March and 'Osceola' which is later flowering, are the best, most
persistent, cool season legumes. Production of dry matter is low, however, until
February or March. Summer survival by white clover is common in many areas. These
clover-grass pastures are best used for brood cows with young calves to insure
rapid "recycling".








During the past 20 years there has been increasing interest in the use of
tropical legume-based pastures. The annuals, alyce clover and hairy indigo are
still being used, and more recently American jointvetch (Aeschynomene americana
L.), has been used successfully on a commercial scale (Hodges et al., 1982).
'Florida' carpon desmodium (Desmodium heterocarpon DC.) was the first Florida
released perennial pasture legume that appears to have most of the attributes
sought in a tropical legume, ie., good animal acceptability, persistence under
grazing, tolerance to moist and periodic flooding, concentrated seed set, and
relatively easy commercial seed harvest (Kretschmer et al., 1979). Carpon des-
modium long-term persistence and association with bahiagrass, even under high
stocking rates, has been good. Another recently released cultivar was 'Florigraze'
peanut (Arachis glabrata L.) which is a very persistent, high quality vegetatively
planted legume, for grazing or hay (Prine et al., 1981).
Because of the successful commercial use of tropical legumes for forage in
south Florida, and the research emphasis on forage legumes, the Agronomy section of
ARECFP began a germplasm bank in the 1960's. It is one of the largest in the world
consisting of about 6000 accessions, the seeds of most are in long-term freezer
storage. "Passport data" of evaluated accessions have been entered into a database
management system for easy referral. Besides seed collection trips to various
tropical American countries, seeds have been obtained from and exchanged with
germplasm centers in Australia, Colombia, the USDA, and elsewhere. The ARECFP
frequently distributes tropical legume seeds to other Research Centers in Florida
and elsewhere upon request. In conjunction with the germplasm bank, a herbarium of
several hundred specimens is maintained and being increased as new accessions are
evaluated.
Evaluation consists of two levels which may be separate or closely meshed.
The first level evaluation of new collections, selections, or breeding lines
includes determining flowering patterns, seeding ability, growth habit, short-term
persistence, and resistance to drought, flooding, cold temperatures, insects, and
diseases. The second evaluation consists of clipping or rating experiments of
legumes in grass mixtures to estimate yield, quality, fertility and lime require-
ments, and/or determining persistence under grazing on commercial ranches. The
Legume Breeder and Agronomist work in close association with Drs. Ronald M. Sonoda
(Plant Pathologist, ARECFP), George H. Snyder (Soil Scientist, Everglades REC-Belle
Glade), Robert C. Bullock (Entomologist, ARECFP) and Brian J. Boman (Engineer,
ARECFP) on problems associated with selection and evaluation in various stages of
legume development. In addition, cooperative work is conducted with extension and
other research personnel in south Florida.
Because of the similarity of forage species being used and evaluated in
Florida and in other tropical areas, and the similarity of diseases, insect problem
in the subtropics and tropics, a bibliography of the work conducted by scientists
at ARECFP or in cooperation with other Florida IFAS research and extension per-
sonnel is being published to disseminate our research results. It is hoped that
similar information may be obtained from researchers in other countries that will
help in our future research.
