I expect that it will take at least three years
before we will be able to observe any measurable
differences from these various treatments. What we
will be looking for are differences in the rate of
plant growth, seed yield, leaf tissue analysis and oil
content of seeds.
In the second written progress report to Berberich as
general partner of JDP, dated May 24, 1983, Whittaker advised
JDP, among other things, that:
In recent months I have had the opportunity to discuss
Jojoba Development Partner's R & D program in detail
with Drs. Dave Palzkill and Bill Feldman at the
University of Arizona, with the technical
representatives of our agri-chemical supply company and
with our farm staff. Dave Palzkill commented on the
need for growers in various areas to carry out R & D
programs such as this and suggested that we compare
notes with Bob Roth of the U of A Extension Services
Station. Dr. Palzkill recommended that, rather than
than [sic] study response to different forms of
nitrogen (in ammonia vs. nitrate vs. urea) or methods
of application (in water, soil or foliarly), we would
do better to study varying amounts over a wider range
than we had anticipated and to include response to
phosphorus in the program. He also pointed out the
need to replicate all trials in the two separate plots.
Following Dr. Palzkill's recommendations, Whittaker revised
the nutrient application program planned for Turtleback I.
Consequently, the 80 acres of Turtleback I were divided into 14
plots of jojoba plants with 15 rows each. Seven application
formulations were devised for those 14 plots, consisting of
varying amounts of nitrogen and phosphate and varying application
periods during the year. Each application formulation was then
applied to 2 of the 14 plots. The primary purpose of the seven
application formulations was to test how to use nutrient
