Abstract

      This study was conducted during the 2021 and 2022 seasons to examine beneficial the positive effects of spraying potassium citrate and potassium acetate at 1.0 to 4.0 each % on the growth, yield and quality of Madjool date palms under the environmental conditions of the Red Sea Governorate. Spraying potassium citrate or potassium acetate three times (after the establishment of the the fruit, at the beginning of Kimri stage and in the Khelal stages) from 1.0 to 4.0% had announced promotion in all growth characteristics, yield, and fruit quality relative to the control treatments.
            A gradual promotion depended on increasing the concentration of each from 1.0 to 4.0% without considerable effect among the two concentrations. In this regard, the spraying of potassium acetate was significantly superior to the use of potassium citrate.  The best results were obtained when potassium acetate (a source of potassium) was applied three times to Madjool date palms at 2.0%.
