Background
Jojoba plants [
Simmondsia chinensis
(Link) Schneider] are appropriate to the semiarid regions; it has the ability to survive in a harsh desert environment and it is very drought-resistant and can be grown on marginal lands without replacing any existing crops. After that, Jojoba is a new oil-producing industrial crop, oil-producing cash crop, and has much of the interest in worldwide in recent years. So, processes are made to increase the seed yield of jojoba as requirements of essential fertilizer and evaluation of new clones. Two field experiments were conducted on five clones (S-BS-, S-700, 610, S-L, and S-G) aged 3 and 13 years from planting at North Sinai, Egypt on sandy soil to study the effect of foliar spray with nitrogen, phosphorus, and boron with three rates of NPB (00, NPB1 (N 1%, P 0.75%, and B 0.4%) and NPB2 (N 1.5%, P1.25% and B 0.8%)) on oil and other contents of jojoba plants.
Results
Results showed that all treatments improved the vegetative growth, yield, and seed quality. Concerning oil, weight of 100 seeds and oil percent in seeds with treatment NPB2 under clone S-700 gave the highest value for all study parameters.
Conclusions
Therefore, for improving yield and seed quality, it could be recommended with foliar spray NPB2 (N1.5%, P 1.25%, and B0.8%) under the condition of this study on jojoba plants.
