Assessment of vineyard vigour and yield spatio-temporal variability based on UAV high resolution multispectral images
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 vegetative and reproductive growth and thus directly or indirectly detect variability. Through the images obtained from UAV, the Vegetation Indices (VIs) can be calculated and compared with various agronomic characteristics of the vineyard. The objective of this study was to evaluate the multispectral response of the vineyard in three specific phenological phases and to analyse the spatial distribution of vegetative vigour. A multirotor UAV equi…
Effects of canopy covering on yield and quality of ‘Nero d’Avola’ (Vitis vinifera L.) grown in hot-arid climate condition
The impact of climate change on grapevine ecophysiology and vineyard management is predicted to be a serious problem in the next years. In fact, it has an influence on the fruit-set, yield, and in modulating decoupling between technological and phenolic ripening. Thus, it is essential to identify costeffective and easy-to-implement solutions to deal with the issue. For this purpose, the present study aims to test different shade treatments (ST) applied directly to the canopy of ′Nero d’Avola′ cultivar (Vitis vinifera L.), trying to limit the excess of light and heat that, usually occur in hot-arid climate areas as in Sicily. Two ST were imposed during the 2020 vegetative season from fruit s…
