were growing in Superior, Arizona. HJI treated some of those
seeds with fungicide and/or germination hormones during the
planting period but observed no measurable differences in the
plants as a result of such treatment.
HJI undertook a program to vary the nutrients to be applied
to the jojoba plants on Turtleback I. Whittaker and Berberich
anticipated that varying the nutrient applications would help HJI
discover how to use nutrient applications to increase seed
productivity of jojoba plants and thereby increase profits.
In the first written progress report to Berberich as general
partner of JDP, dated August 26, 1982, Whittaker advised JDP,
among other things:
Due to the limited size of the R & D program under
contract with Jojoba Development Partners, it will not
be possible to carry out all of the R & D projects
planned for a 454-acre project. The 80-acre planting
for JDP (and JDP II) will allow us to do an excellent
study on the effects of various nutrient applications.
Commencing this month we are dividing Turtleback I into
10 experimental plots and intend to apply the following
treatments:
1. Control: no treatment
2. Nitrosul: applied in irrigation water
3. Urea: applied directly to plant roots through
soil
4. Urea: foliar application
5. Ammonia: applied directly to plant roots
through soil
6. Micronutrients: applied foliarly
7. Numbers 6 and 2 combined
8. Numbers 6 and 3 combined
9. Numbers 6 and 4 combined
10. Numbers 6 and 5 combined
The foliar applications will not begin until at
least spring of 1983 when there is new growth on the
plants.
