Assessment of vineyard vigour and yield spatio-temporal variability based on UAV high resolution multispectral images [PDF]

, 2023
Accurate, timely assessment of the vineyard on a field scale is essential for successful grape yield and quality. Remote sensing can be an effective and useful monitoring tool, as data from sensors on board Unmanned Aerial Vehicles (UAV) can measure ...

Variability of vineyard peach tree characteristics

Genetika, 2008
Vineyard peach seedlings are the most important rootstock for peach in Serbia and abroad. High variability is a characteristic of the vineyard peach planting material that is used as rootstock in nursery production. Through work of many years, vineyard peach genotypes with qualitative traits were selected and collected.

Origin and fate of copper in a small Mediterranean vineyard catchment: New insights from combined chemical extraction and δ65Cu isotopic composition [PDF]

, 2013
For centuries, many Mediterranean catchments were covered with vineyards in which copper was widely applied to protect grapevines against fungus. In the Mediterranean-type flow regime, brief and intense flood events increase the stream water discharge by

Comparison between satellite and ground data with UAV-based information to analyse vineyard spatio-temporal variability

OENO One, 2020
Currently, the greatest challenge for vine growers is to improve the yield and quality of grapes by minimizing costs and environmental impacts. This goal can be achieved through a better knowledge of vineyard spatial variability.
