The objective of the present study is to investigate the effects of spraying Saidy date palm bunches with potassium silicate (PS) (0.5% and 1 %) and zinc sulphate (ZS) (500 and 1000 ppm) and their combinations on yield components (bunch weight) and fruit physical and chemical characteristics. The present study was carried out during 2021 and 2022 seasons on 20 years old date palms grown on a farm in district Baris - New Valley Governorate - Egypt. The experiment was arranged in a randomized complete block design (RCBD) including nine treatments with seven replications of one bunch each. Results indicated that all spraying treatments significantly increased yield and improved fruit physical and chemical characteristics compared to control. Spraying bunches with 1% potassium silicate plus 500-ppm zinc sulphate was a more effective treatment in increasing yield

components and improving components fruits' physical and chemical properties and fruit physical and chemical characteristics
