Three commercial nano-composite's, Active humic acid, Hypertonic, and Root fast, each
at 2.5, 5, and 10 g/palm tree, were tested during the 2020 and 2021 growing seasons for their ability to
mitigate the adverse effects of soil and irrigation water salinity on the fruiting of Sakkoti date palms
grown in sandy soil. The salinities of soil and irrigation water were 2400 and 2800 ppm, respectively.
In comparison to the control, all treatments significantly increased the leaf content of total chlorophylls,
nitrogen (N), phosphorus (P), and potassium (K) as well as the leaf area. In addition, these treatments
increased the bunch weight, yield/palm tree, and fruit quality attributes. The increasing of the
parameters under investigation was related to the concentration increase. In descending order, Active
humic acid, Hypertonic, and Root fast were the best nanocomposites. Each nanocomposite's soil
additive dose was increased from 5 to 10. However, this did not result in any discernible improvement.
The most striking effect on mitigating the salinity-induced adverse effects on fruiting and promoting
yield and fruit attributes of Sakkoti date palm is the soil addition of Root fast at 5 g. / palm tree/ year.
