Portugal, one of the Mediterranean countries with highest density of autochthonous cultivars, has 169 red, 152 white, and 22 grey cultivars approved for wine production (Ordinance 380/2012, 22nd November).

The aim of this investigation was to examine the possibility of using “berry-cup” technique to study K phloem unloading and accumulation of K in ripening grape berries, in field conditions.

Many vineyards along the world produce high yield and high alcohol level wines because of different factors, so bunch thinning technique has become more usual in order to balance the production.

The Diagnosis and Recommendation Integrated System (DRIS) consists of an integrated set of norms representing calibrations of plant tissue composition, soil composition, environmental parameters and farming practices as function of yield of a particular crop.

There are several aspects influencing the quality of grapes. This paper deals with the effect of variety, rootstock and vintage on levels of yeast assimilable nitrogen in grape musts.

The Brazilian viticulture is mainly characterized by the cultivation of American grapevines (Vitis labrusca L.), between them cv.

Green manures have become an important option for recycling nutrients in organic cropping. However, its benefits are often not obtained in the short term.

A total of 704 Cabernet Sauvignon (CS8) vines were grafted on 10 different rootstocks and compared to an own-rooted control as part of a new vineyard planting on the terraces above the Estrella River in the Paso Robles AVA.

Maintaining grapevine productivity and wine quality with limited inputs (drought, low nitrogen supply) is crucial in Mediterranean areas.

In many important viticultural areas of the Mediterranean basin, plants often face prolonged periods of scarce iron (Fe) availability in the soil.
