EFFICIENCY OF ZINC, SILVER AND CHITOSAN NANOPARTICLES SPRAY ON YIELD AND FRUIT QUALITY OF ZAGHLOUL..

This study examined the effects of pre-harvest applications of zinc oxide, silver, and chitosan nanoparticles at 30, 60, and 90 ppm on yield and fruit quality of “Zaghloul” date palm fruits to untreated fruits over the 2018 and 2019 seasons. All treatments were sprayed on bunches three times: once at the start of growth, once after fruit set, and once a month later. The sprayed fruits were collected in September at the Khalal stage, and yield and quality were assessed on the day of harvest. The best treatment was zinc oxide nanoparticles at 90 ppm, which boosted yield, bunches weight, fruit weight, fruit dimension and volume, as well as total soluble solids, total sugars, and total anthocyanin content. Furthermore, it had the lowest total acidity, total soluble tannins, and total phenolic content of any of the varieties. According to the findings, pre-harvest treatment of zinc oxide, silver, and chitosan nanoparticles could be a good candidate fertiliser for boosting the yield and general features of date palm fruit from the “Zaghloul” variety.
