Abstract
|
Foliar fertilization is one of the crucial ways for continued cultivation of date palm, obtaining the best results
of growth and production, in addition to the possibility to reduce damage from abiotic stress. Although subjected date palm to an annual fertilization program, it faces some challenges, including low soil availability
for nutrients, dryness of the soil surface, low root activity in the breeding period, soil alkalinity, as well as
water scarcity in areas of cultivation, and symptoms of deficiency of some elements. This review attempts to
shed light on the importance of using leaf fertilization, demonstrating the successful technique and positive
results, and proving the ability of date palm cells to absorb nutrients, similar to other trees, and interact with
chemical and biological fertilizers. Besides, the leaflet’s possibility of absorbing various nutrients, chelated
iron, biostimulants, antioxidants, and nano-fertilization, are presented.
