The current study was carried out in a private vineyard located west of Abu Qirqas Center, Minia Governorate, Egypt. The study was set out to investigate the impact of K-silicate and/or seaweed extract on growth and chemical content of Banaty grapevines, during the two consecutive seasons in 2021 and 2022 with on 30 vines from Banaty Seedless grapevines (10-years old). The experiment was arranged in Randomized complete block design included 10 treatments individual or combined of the potassium silicate and seaweed extract as foliar application with three replicates as following; control (sprayed with tap water), (0.05, 0.1 % 0.2% for each of K-silicate or seaweed extract and the same concentrations for each application combined together. The results indicated that all vegetative aspects and leaves chemical content were increased with increasing studied concentration and the highest mean values scored with foliar application at -silicate (0.2%)+seaweed extract (0.2%) without significant difference with the lower concentration. So, it could be suggested to use lower concentration 0.1% for each of the applications under the same conditions.
