In the context of vineyard and wine process management, producers are looking for novel tools to estimate the growth stage and potential quality of vine grapes. Several studies show the importance of the berry size as a growing and quality indicator. This paper proposes an image processing method to estimate the berry size of vine grapes by image acquisition in the field. The goal is to recover...

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...

• Environment, and its inevitable season-to-season weather variations, is considered the main source of fluctuation in vintage quality within a region. In a 1992 study, the ideal vineyard climate was described as one with “consistently warm days –not hotand consistently cool nights throughout the growing season, but particularly around veraison, when maximum carbohydrate accumulation for color ...

Plastic covering is used worldwide to protect crops against damaging growing conditions. This agricultural practice raises some controversial issues. While it significantly impacts on local economic vitality, plasticulture also shows several environmental affects. In the Apulia Region (Italy) the wide-spreading of artificial plastic coverings for vineyard protection has showed negative conseque...

Viruses are ubiquitous and present in a wide range of settings, from living organisms to various environments. Although viruses are regarded as important pathogens in higher plants, viral populations in specific host plants have not yet been fully examined. This study revealed viral populations in grape berries obtained from a cultivar from a single vineyard using currently available grapevine ...

Issue Established in 1995, the Lodi Winegrape Comission’s (LWC) Sustainable Winegrowing Program (SWP) promotes grower adoption of best management practices via informational meetings, workshops, vineyard demonstrations and research, the Lodi Winegrowers’ Workbook for sustainability self-assessment, and the Lodi Rules for Sustainable Winegrowing third-party certification program. Understanding g...

Vineyard irrigation management in temperate zones requires knowledge of the crop water requirements, especially context climate change. The main objective this work was to estimate evapotranspiration (ETc) Vitis vinifera cv. Loureiro for local conditions, applying dual coefficient approach. study carried out a vineyard during two growing seasons (2019–2020). Three treatments, full (FI), deficit...
