Vine responses to two irrigation systems in the region of Vinhos Verdes
In this work we try to know the influence of two irrigation systems (Drip and Micro – jet ) with the same levels of water applied in an experimental vineyard in the region of Felgueiras.
At present we must say that there are not significant differences between the modalities in 1996, when we refer the yield and the pruning weight by vine. In 1998, we modified slightly the trial because there were troubles with some vines of one treatment. In 1999, we verified large significant differences among the modalities relatively to the pruning weight by vine but there were not significant differences at the yield/vine.
At the moment we do not have enough results about the relations quality of wine and amounts of water applied to the soil and their form of administration. So, we cannot conclude definitively about these two systems of irrigation and their levels of water applied. However, we can say that the treatment «Drip 100%Etm» did not show good results up to now.
