Abstract

This work was performed in the two experimental seasons of 2020 and 2021 at the farm of the Faculty of Agriculture, Minia University, Egypt to study the effect of compost (0.0, 500, 1000 and 1500 g/container) and some stimulating substances (control, vitamin E at 100 ppm, bread yeast at 10 g/l and garlic extract at 10%) on leaves and some chemical composition of jojoba (Simmondsia chinensis, Link) plants. Data showed that all used levels of compost pronounced increased leaves traits (number, leaf area, leaves weights (fresh or dry) in addition to chemical composition (pigments content, NPK percentages and protein) compared with the control. The 1500 g compost/container was more active than other treatments. Also, sprayed plants with vitamin E, active yeast and garlic extract significantly improved all previous parameters compared with the control. In general, the treatment of active yeast was superior, followed by garlic extract than vitamin E treatment. Therefore, the best interaction treatment was recorded with the high level of compost (1500 g/container) plus bread active yeast (10 g/l) or garlic extract (10 %).
