INTEGRATED TECHNIQUES FOR VINEYARD VARIABILITY EVALUATION
Acta Horticulturae, 2007European wine producers pay great attention to proper vine canopy management, mainly to improve final product quality, reducing yield fluctuation and creating the best microclimatic conditions for grape development. The success of these operations depends on a series of factors, like vine being and vineyard organisation, meteorological seasonal trend ...

VRDI - Variable Rate Drip Irrigation in Vineyards
Advances in Animal Biosciences, 2017Vineyards worldwide are subjected to spatial variability, which can be exhibited in both low and high yield areas. We developed a variable rate drip irrigation (VRDI) concept to reduce such variability. The VRDI system divides the vineyard into 30×30-meter irrigation zones, enabling individual irrigation of each zone according to normalized difference ...

Real-Time Variable Rate Spraying in Orchards and Vineyards: A Review
Journal of The Institution of Engineers (India): Series A, 2018Effective and efficient use of pesticides in the orchards is of concern since many years. With the conventional constant rate sprayers, equal dose of pesticide is applied to each tree. Since, there is great variation in size and shape of each tree in the orchard, trees gets either oversprayed or undersprayed. Real-time variable rate spraying technology

Spatial variability in Ontario Riesling vineyards. II. Berry composition
Canadian Journal of Plant Science, 2020Spatial variability of berry composition was studied over a 3-yr period in 10 Riesling vineyards in the Niagara Peninsula in Ontario. Vineyards were delineated using global positioning systems (GPS), and 75–80 sentinel vines were georeferenced within a sampling grid for data collection.

Compositions and chemical variability of grape pomaces from French vineyard
Industrial Crops and Products, 2013Compositions of 8 pomace samples originating from red and white winemaking from different areas of production of French vineyard were characterized (Alsace, Bordeaux, Bourgogne, Champagne, Languedoc, Val de Loire and Provence). Large variabilities were observed depending on cultivar and grape varieties: pomace samples contained 3-6% w/w of oil and 20 ...

Using Grape Leaf Reflectance for Spatially Variable Vineyard Management
2004, Ottawa, Canada August 1 - 4, 2004, 2004Spectral reflectance of grape leaves was measured over the range of 450-2400 nm. Reflectance spectra of leaves from healthy and phylloxera-infested vines were compared and significant differences were noted in the visible part of the spectrum. A Green-Red Ratio (GRR) was evaluated to distinguish between the two groups of leaves.
