Use of the stics crop model as a tool to inform vineyard zonages

Abstract

[English version below]

STICS est un modèle de culture développé à l’INRA (France) depuis 1996. Il simule les bilans de carbone, d’eau et d’azote dans le système culture-sol, piloté par des données climatiques journaliéres. Il calcule à la fois des variables agricoles (rendement en quantité et qualité) et environnementales (pertes en eau et en azote). Une des originalités de STICS est son adaptabilité à de nombreuses cultures (herbacées, ligneuses, annuelles, pérennes) rendue possible par le choix de paramètres génériques et d’options de formalismes. Le travail présenté traite, dans un premier temps, des spécificités de STICS pour la vigne en terme de bilan trophique, de fonctionnement énergétique et hydrique et d’estimation des teneurs en sucre en en eau du raisin. Nous montrons ensuite diverses sorties du modèle qui permettent de caractériser des terroirs du vignoble des Côtes du Rhône.

STICS is a crop model developed at INRA (France) since 1996. It simulates the carbon, water and nitrogen balances of the crop-soil system driven by daily climatic data. It calculates both agricultural variables (yield in terms of quantity and quality) and environmental variables (water and nitrogen losses). One of the key elements of STICS is its adaptability to various crops (herbaceous, ligneous, annuals, perennials) made possible by the choice of generic parameters and options for both crop physiology and crop techniques. The present work deals first with the particularity of STICS to simulate vineyard in terms of trophic balance, energetic and water functioning and assessment of sugar and water contents of grape. Second it shows the various outputs which can be calculated by the model in order to characterize typical Côtes du Rhône zones.

Viticultura protegida: uso de mallas sombreadoras fotoselectivas como una herramienta para enfrentar la crisis climática en uva de mesa en el norte de Chile

The production of table grapes in Chile is of great importance, being one of the main established fruit crops with over 43,000 hectares distributed across a diverse climate range, from the southern limit of the Atacama desert to the mediterranean zone. Chile is also one of the leading exporters of table grapes. producers must confront the challenges posed by the climate crisis, such as decreased rainfall, increased heatwaves, and extreme temperature events during the growing season, mainly associated with desertification in northern Chile (Atacama and Coquimbo regions).

Distribution of photosynthates towards the grapes: effects of leaf removal and cluster thinning applied before veraison in cv. Verdejo

The relationship between grape production and leaf surface is a highly debated aspect in terms of the impact it may have on the composition and quality of grapes, especially in areas that focus their cultivation on high-quality wine. In many occasions, the limitation of the unitary production level in these areas is claimed to be the main factor for achieving high quality levels in the wine, forgetting the importance of the source-sink relationship and other environmental factors and management of the canopy. Taking this consideration into account, this work seeks to know the response of the vine as a whole, and the individual shoot as well, to the application of various alternatives of leaves and clusters removal, carried out in the phase immediately before veraison, in cv. Verdejo, in Spain.
