PROJECT TITLE: Jojoba (Simondsia chinensis) A New Oil Crop for Florida
PROJECT LEADER: Bijan Dehgan ..-h2, R/R/
-LOCATION: Department of Ornamental Horticulture
University of Florida
Gainesville, FL 32611
To provide-technical and cultural information for establishment of
jojoba as a new "oil" (liquid wax) crop in Florida. Knowledge concerning
its: cultivation, selection and propagation of cold tolerant plants, planting
techniques, growth control (nutrient requirements, irrigation, pest control)
and harvest of seeds to be elucidated through field trials and greenhouse
TASKS TO BE PERFORMED (April 1-, 1982 through June 30, 1983)
1. Propagate-seeds and vegetative material in Ornamental Horticulture green-
houses. Tissue culturihg of superior selections of jojoba with larger or
more numerous seeds, higher oil content and/or cold tolerance will be
2. Seed propagated plants will be cultivated in one acre plots at Ft.
Lauderdale, Apopka, Ona, Dover and Monticello Experiment Stations as well
as Gainesville. This will provide a climatic and edaphic cross section
of.State, hence, feasibility of cultivation at each of these locations
will be realized.
S3. Periodic site visits of approximately once-every three months will be made
to each of the above stations to evaluate establishment and growth of
plants. Measurements of growth rate during the year will provide a base
for development of a positive correlation between soil characters (texture,
structure; moisture content, nutritional status, etc.) and rainfall-
irrigation frequencies. Evaluation of cold tolerance of plants will
also be determined by these site visits.
4. An experiment will be set up in the Ornamental Horticulture greenhouses in
Gainesville to determine nutritional (macro and micronutrients) requirements
of jojoba plants. Despite several years of research in California,
Arizona and elsewhere, not a single.study, to our knowledge, has dealt
with the question of nutrient deficiencies or excesses. Acid washed gravel
of uniform size will be used in a hydroponic fashion to perform this study.
5. Concomitant with "4" above, selected plants in each of the field trials
will be given varying amounts and frequencies of fertilizers (based on
soil analysis) to determine growth responses of plants to availability
.6. 'The data collected during the course of several years (except no.4) will
be published in scientific journals as well as university Extension
publications. The results of the experiment in "4" will be published as
soon as the symptoms become apparent.
JUSTIFICATION AND POTENTIAL CONTRIBUTIONS
OF THIS RESEARCH TO FLORIDA
Potential and actual uses of jojoba oil (a liquid wax) in lubrication,
cosmetics, pharmaceuticals, food cooking oil, salad oil, vegetable oil,
.shortening, replacement for certain waxes, animal feed supplements and many
other uses not yet determined, leaves little doubt as to the enormous economic,
social and conservation value of this plant. According to our calculations,
there are 1,160,462 acres of land in Florida that are suitable for jojoba
plantations. These are well drained non-agricultural lands. There are also
large tracts of land, such as phosphate mining areas that need to be evaluated.
A number of advantages are inherent in jojoba cultivation;
The plants have longevity of many years, thus functioning as a renewable
resource, the oil supply increasing with time.
Relatively large amounts of oil can be produced per acre, thus reducing
our dependence on import of whale oil and petroleum.
As a substitute for whale and industrial oils, jojoba oil may be considered
.the single most important contribution toward conservation of natural resources.
-.An economically viable agricultural commodity canrbe created .in marginal
lands including disturbed mining sites, where little else can be grown.
Large seeds lend themselves to easy extraction. The jojoba seed is
analogous to a ready-made, highly refind oil supply. There is no pollution and
the seed meal is reputed to be ideal for chicken feed.
An economic base is provided for families with little income but perhaps
some marginally suitable land to provide oil for personal use as well sale to
. the industry.
