Commercial pruning practice in jojoba plantations is traditionally dictated by maintenance requirements only. It enables machine movement between the plants and efficient harvest but is not designed to maximize long-term productivity. In this study, mechanical and manual pruning approaches were tested in two cultivars in a mature jojoba plantation, in comparison to the common practice. These new approaches were designed to enable better light penetration into the canopy, aiming to improve growth and productivity. As jojoba is an alternate bearing crop, the vegetative and reproductive performances were observed over four years, by remote sensing and manual measurements. The pruning type and strategy had a significant effect on growth, with a distinction between the two tested cultivars. Top-pruning methods were found to best encourage new branching and yield, while side-pruning practices were less effective. Several treatments, including hedge pruning, attenuated or eliminated the alternation cycle. We conclude that using the proposed pruning practices would be beneficial in jojoba cultivation, and that the specific method should be suited to the cultivar characteristics.
