The effect of foliar silikon applications on nutrition status some quality characteristics and yield of wine grape (Shiraz) grown under water stress

This research was conducted in Manisa province Turgutlu-Cepnidere region. The manufacturer's vineyard Shiraz wine grape varieties to the breeding (2013) was conducted with an attempt established for a period of one years. Trials conducted under irrigated and water stress conditions in the control and three different silikon (K2SiO3) levels (0-4-8-16 g L-1 Si) was applied. As a result of these applications, some nutrients and quality items were examined. As a result of research, application K2SiO3 performed in plots; panicle weight, yield per grape omca, water soluble dry matter (Brix), titratable acidity and iron nutrient were found to be statistically significant. The effect of K2SiO3 on yield, quality and utrients was found to be statistically significant, especially in water stres conditions.
