Proper fertilization of vineyards represents an important component of viticultural technology that can have a significant impact on the quality and quantity of grapes harvests. Rational use of fertilizers contributes to the development of a healthy vineyards, leading to enhanced yields and quality production. This study focuses on Moldova table grape variety, characterized by a late ripening period in late September and a productivity range of 17-18 t/ha. The research investigates the effects of calcium treatments on the physiological parameters of grapevine plants, as well as the quality and quantity of grape yield. Research findings lead to the following conclusions: Calcium treatments directly influence physiological indices of grapevines. The variants with a higher number of treatments recorded maximum values of chlorophyll content index and berries firmness (particularly variant 10 with 4 treatments, followed by variants with 3, 2 and 1 treatments). Calcium treatments significantly affect the chlorophyll content index and berry firmness, with lesser impact observed on other agrobiological characteristics of the variety.
