The current study was carried out in a private vineyard located west of Abu Qirqas Center, Minia Governorate, Egypt during the two consecutive seasons in 2021 and 2022 with on 30 vines from Banaty Seedless grapevines (10-years old), to investigate the impact of the foliar application with K-silicate and/or seaweed extract on production, and quality of Banaty grapevines, the trial 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 yield, cluster and berry quality were increased with increasing studied concentration, except the average of shot berry% and total acidity were decreased. The highest mean values scored with foliar application at -silicate (0.2%) + seaweed extract (0.2%) without significant difference with the lower concentration, which recorded the lowest values of shot berry% and total acidity. So, it could be suggested to use lower concentration 0.1% for each of the applications under the same conditions.
