Throughout 2021 and 2022 seasons, Zaghlul date palm was fertilized with NPKMg via nano-technology system versus traditional fertilizers. Three doses of both, NPKMg nano-fertilizers and through   conventional mineral NPKMg fertilizers were added to each palm/ year. All nutrients were added via fertigation except Mg used via foliage spraying. The target was examining the effect of using NPKMg fertilizers versus normal ones on the fruiting of Zaghloul date palm. Treating Zaghloul date palm with NPKMg via nano fertilizers regardless to the levels was measurably superior to using these fertilizers, via traditional methods in enhancing yield and fruit quality. Varying NPKMg levels applied via a nano-system from 100 to 200, 50 to 100, 50 to 100, and 20 to 40 g/ palm/year, respectively had negligible promotion on all the studied parameters. Supplying Zaghloul date palm grown under sandy soil with NPKMg via nano-technology system at 100, 50, 50, and 20 g/palm/year, respectively succeeded in improving yield and fruit traits.
