dc.description.abstractWith the aim of studying the mechanization of vine pruning while still maintaining plant vigor and fertility of the soil, this study has tested the use of different types of fertilization in mechanical and manual pruning, in two different estates. The vinification of the grapes took place in the cellar of the Instituto Superior de Agronomia where, after natural clarification and stabilization the wines were bottled and subsequently analyzed. The analyzes were made on each of the different samples and consisted in the following parameters: Alcohol, Total Dry Extract, Total Acidity, Total Polyphenols, Total Anthocyanins, Color Intensity, Color tone, as well as the levels of Iron, Potassium, Calcium and Copper. In terms of results, the wines showed very similar parameters with small changes in values, but when subjected to a statistical analysis the results revealed not statistically significant, with the exception of Color tone and Potassium, although with very close values as well. With regard to sensory analysis it was observed a consistency in terms of results with the chemical analyzes, and it was also not evident a standard differentiator between the samples, confirmed by the variance analysis performed.por
