Abstract: Abstract Potassium fertilization can change K forms available in the soil, as well as influence plant absorption of it and yield but, mainly, it can affect grape composition. The aim of the current study was to investigate the impact of potassium (K) fertilization on grape production and juice (must) composition of a Cabernet Sauvignon cultivar. Grapevines were treated with 0, 50, 100, 150 and 200 kg ha-1 year-1 K2O. Leaf K contents, grape yield per plant and area, total soluble solids (TSS), must pH and titr…
