The effect of foliar applied potassium fertilizers on nutrition status and some quality characteristics of wine grape (Shiraz)

Study in Manisa province Turgutlu - Cepnidere in the region. The manufacturer's vineyard Shiraz wine grape varieties to the breeding (2013-2014) was conducted with an attempt established for a period of two years. Trials conducted under irrigated conditions in the control and five different potassium fertilizer (KNO3, K2SO4, KTS, K2CO3, and K-FOS) was applied. As a result of these applications, some nutrients and quality items were examined. As a result of research, application K2CO3 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. K-FOS application; panicle length, phosphorus and magnesium nutrientswere found to be statistically significant. KTS application; grain width and length were found to be statistically significant. K2SO4 application; panicle width and copper nutrient were found to be statistically significant nutrient. KNO3 application; nitrogen nutrient were found to be statistically significant.
