Abstract:		"Vineyard management can influence the growth and yield components in the vineyards and therefore on the grape and wine quality. In this work, a chemical study was conducted (2014-2015) to examine the effect of fertigation on chemical composition of Albarino. A control (Rain-fed) and fertigation (60% and 100%) treatments were apply at same irrigation depth, where fertigation 100% is complete nutrient requirements to Albarino trellis system in this location (Rias Baixas AOC, NW Spain). Results showed that non-volatile compounds of Albarino musts were not affected by fertigation treatments. However, the effect of fertigation treatments on the volatile composition was observed. Terpenes and C(13)-norisoprenids were the most affected families of volatile compounds by fertigation treatments, where 60% fertigation exhibited the highest concentration, improving the wine aroma quality. Application of principal component analysis (PCA) showed a good separation of Albarino grape according to fertigation treatments and vintages"
