Geospatial technologies in spatially defined viticulture: case study of a vineyard with Agiorgitiko variety in Koutsi, Nemea, Greece


Context and purpose of the study – Geospatial technologies have significant contribution to viticulture, especially in small-scale vineyards, which require precise management. Geospatial data collected by modern technologies, such as Unmanned Aerial Vehicle (UAV) and satellite imagery, can be processed by modern software and easily be stored and transferred to GIS environments, highlighting important information about the health of vine plants, the yield of grapes and the wine, especially in wine-making varieties. The identification of field variability is very important, particularly for the production of high quality wine. Modern geospatial data management technologies are used to achieve an easy and effortless localization of the fields’ variability. The aim of this study is to record and investigate the variability of all factors (soil, relief, etc.) that affect the qualitative and quantitative yield of the vineyard and their correlation to the characteristics of yield.

Material and methods – The study area is located in Koutsi, a region of the Municipality of Nemea, which is a famous area for its early ripening vineyards. The 1.3 ha vineyard was planted in 1980 with the Black Nemea (Agiorgitiko) variety on 41B rootstock, with planting distances of 2.30 x 1.20 m and planting density of 362 stumps per 0.1 ha. The orientation of the planting lines is North to South. The vineyard was divided into 13 blocks of about 0.1 ha each, after its study by orthomosaic, collected from UAV, and taking into account the planting lines and its shape. From each block, soil samples were collected in areas with different color (macroscopic observation using UAV data), at 13 points, in two depths of 0-30 cm and 30-60 cm. Soil analysis showed that the soil is characterized as normal, heavy clayey, moderately alkaline, moderate in organic matter, adequately supplied with phosphorus (P), poor in potassium (K), slightly low in boron (B), and low to moderate levels of trace elements. Total calcium carbonate (CaCO3) ranges from 56 to 74%, except for one sampling site which is approximately 30%. Harvesting conducted in early September when Baume degrees were greater than 13o. UAV flights were conducted using the DJI Matrice 100, DJI Phantom 3 and Sensefly Ebee platforms. The sensors used for this study were Parrot Sequoia (bands: G (550nm), R (660nm), Red-Edge (735nm) and Near-Infrared (790nm), RGB) and a modified Go-Pro camera.

Results – The obtained UAV images were used to extract Digital Terrain Model (DTM) and orthomosaic. Altitude and slope were calculated in the vineyard using the DTM. The orthomosaic was used to observe the phenotypic characteristics of the vineyard, such as soil variation (e.g. soil color) and cultivation characteristics. Thus, it was possible to monitor the condition of the vineyard in order to schedule and apply the required cultivation techniques and procedures. Important observations have been also made through vegetation indices. Exporting indices, such as Normalized Difference Vegetation Index (NDVI) supplied valuable information on the vigor and plant health of the vineyard. Thematic maps related to fertilization, irrigation and plant protection were also created. Using this information, cultivation techniques were more efficient, because farmers could focus on plants which were less productive and in need of more nutrients. Finally, thematic maps were useful in delineating management zones, which is extremely beneficial to viticulture.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
