Recently, some studies have been conducted to optimize traditional nitrogen supplementation of the soil by promoting the foliar application of different nitrogen sources such as phenylalanine and urea.

Every year, after the inflorescences counting in spring, a certain loss in the number of clusters was observed at the harvest.

Global warming is causing early harvests because of the fast grape total soluble solids accumulation.

We evaluated 5 trellis systems and 12 clones in 2 separate experiments with the goal of measuring the effect on yield, ripening, and fruit quality.

Spontaneous cover cropping is a common practice in Mediterranean vineyards because it is often seen as less competitive and easier to manage than sown covercrops.

The work was carried out with five white Vitis vinifera, L. varieties (Verdejo, Tempranillo Blanco, Airén, Macabeo and Albariño), four of them cultivated in the Denomination of Origin (D.O.) where they have the greatest area planted of Spain (Verdejo in Rueda, Tempranillo Blanco in Rioja, Airén in La Mancha and Albariño in Rías Baixas) and Macabeo, that although it is not the most important variety in Extremadura, its study was considered there for the importance that it has in all Spain.

There is some evidence that sugar accumulation is retarded in minimally pruned vines.

Superior Seedless is a table grape cultivar mainly produced in San Juan.

The technological importance of phenolic compounds, especially flavonoids, is well known.

Maintaining grapevine productivity with limited inputs is crucial in Mediterranean areas.

Production of high quality grapes requires balanced vines, assessed through leaf to fruit ratio or Ravaz Index (RI).

The study site was on the alluvial zone of the Tunuyán river, Mendoza, a geomorphology with incidence in soil attributes.

Dormancy is a survival strategy for withstanding exposure to adverse environmental conditions.

Worldwide, the wine industry is interested in the influence of terroir on wine characteristics and, in particular, on the soil processes and properties influencing the wine quality.

Vineyard soils are subjected to a substantial depletion of the organic fraction due to intensive farming systems, the reduction of row spacing and the fast evolution of vineyard mechanization.
