The research was carried out on Saidy date palms in the Balat region of the New Valley Governorate, Egypt, during the 2022 and 2023 seasons (latitude 25.591052° and longitude 29.276383°). To investigate how various potassium sources affect the productivity and fruit quality of saidy dates. With seven treatments and five repetitions, one lot each, the experiment was set up in a fully randomized block design. In summary, the findings of this study are as follows In comparison to spraying water (check treatment), foliar potassium citrate or potassium silicate and potassium thiosulfate considerably increased the fruit retention percentage, bunch weight, and yield per palm. No discernible differences were observed among these treatments for most of the attributes studied. In addition, compared to spraying water (check treatment), spraying potassium citrate, potassium silicate, or potassium thiosulfate at any dose under study greatly improved fruit quality in terms of a considerable increase in fruit weight, fruit dimensions, and fruit chemical contents. In general view, using potassium citrate gave the highest values of studied traits.Therefore, based on the study's findings, it is possible to draw the conclusion that, to achieve a high yield with favorable qualities and, consequently, higher market value, date bunches must be sprayed with 2 cm3/L of potassium citrate.
