Impact de différentes modalités de non travail du sol sur le développement végétatif et fructifère de la vigne

Abstract : To refrain from cover crop tilling is an interesting management tactic to avoid the soil erosion of vineyards. Nevertheless, the climatic constraints in southern France tend to limit the adoption of this practice, despite the agronomic and environmental advantages that it presents. Recently however, the implementation of cover crops has seen renewed interest. This observation led the laboratory Natoli & associés to consider the impact of inter-row grass cover on vines in southern France. The purpose of this report is to evaluate the effect that inter row grassing has on the vine. This study is based on several direct and indirect indicators on the vine's vegetative and fruit-bearing development. The purpose of this study is to reflect on the management of inter row plant cover, and how to adapt these practices to the cultivation of grape vines. A statistical analysis underlines a minor plant cover effect on vines during the 2020 vintage. A slight competition for water resources is highlighted but doesn't seem impact the year's production. The comparison of two destructive methods for grass tended to favour rolling over mowing. These results highlight the diversity and the complexity of cover crops. They provide some answers on how to conceive them in southern France.
