GiESCO 2017 – Session 5: Vineyard management

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.

Different types of trellis systems determine different canopy spatial distributions, allowing greater or lesser shoot density in order to maximize the efficiency of light interception and productivity.

The Mediterranean Basin is marked by a strong pressure on water resources, which could reach a critical threshold with the increase of the demand and the decrease of its availability, both linked to the population growth and climate change.

Within the current context of climate change, the choice of variety and rootstock for each specific pedo-climatite becomes critical.

The impact of different canopy systems and viticultural management practices on fruit exposure have been widely investigated, and the potential impact of microclimate on fruit composition is well recognised.

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.

Physiological and productive responses of table grape cv. Red Globe to different regulated deficit irrigation schedules were studied as strategy for facing the increasing water scarcity which affects Chilean table grape producing areas.

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

Radiation plays a key role on yield and quality. A high variability in incident radiation is observed within the leaves and grapes of a single canopy.

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 currently trellis-training system that achieves high yields, comparable to a parral, with high-quality wine and the possibility of machine harvest.

The yield and irrigation strategies have an effect in maturity and chemical profile of grape, also an effect on the sensorial profile of the wine.

Important vineyard irrigated areas of Mendoza show salinity problems.

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.

Castilla-La Mancha region (Spain) is an important viticulture region with 500.000 hectares occupied by vineyards.
