In order to study the effect of potassium (K), iron (Fe), boron (B) and three antioxidants (ascorbic acid, citric acid and salicylic acid) on vegetative growth, photosynthesis pigments, mineral status and yield of Medjool date palm grown under sandy soil conditions, drip irrigation system was followed. located at Malawi district, El-Minia – Egypt. A field trial, designed in split plots, was achieved. The obtained results showed that, increasing K concentration from 0.25% to 0.75% was very effective in improving the vegetative growth, leaf chlorophyll, mineral status, and yield. However, sprayed the ‘Medjool’ date palm with the antioxidants showed a superior effect than spraying Fe of B. Furthermore, the palms treated with potassium at .75% combined with salicylic acid at 100 ppm presented the best results, during the two experimental seasons.
