The use of cover crops in vineyards is expected to increase due to the strong encouragement by European agricultural policy and their contribution to reducing soil erosion. This paper presents the results obtained over three years in a vineyard of the “Pedro Ximénez” variety organically grown in southern Spain. The influence on production, vigor, and grape quality of a seeded cover crop versus tillage was compared using field data and imagery acquired by an uncrewed aerial vehicle. The vines under tillage showed greater vegetative development and yield than those with cover crops between rows. The grapes from the vines under the cover crop treatment ripened earlier and presented higher values of total soluble solids, characteristics that can be useful in the protected designation of origin where the study field is placed. However, the strong yield reduction caused by the cover crop treatment encourages future research to explore other cover crop species that could contribute to improving soil properties without compromising the profitability of the vineyard. This is the first time that the influence of cover cropping on the agronomic and oenological parameters of organically grown white vineyard varieties such as “Pedro Ximénez” has been assessed using field and UAV data.

由于欧洲农业政策的大力鼓励及其对减少水土流失的贡献，预计葡萄园中覆盖作物的使用将会增加。本文介绍了西班牙南部有机种植的“Pedro Ximénez”品种的葡萄园三年来所获得的结果。使用实地数据和无人驾驶飞行器获取的图像，比较了播种覆盖作物与耕作对产量、活力和葡萄质量的影响。与行间覆盖作物相比，耕作的葡萄藤显示出更好的营养发育和产量。经过覆盖作物处理的葡萄藤上的葡萄成熟得更早，可溶性固体总量更高，这些特征可用于研究田地的原产地保护指定。然而，覆盖作物处理导致的产量大幅下降，鼓励未来的研究探索其他覆盖作物品种，这些品种可能有助于改善土壤特性，而不影响葡萄园的盈利能力。这是首次使用田间和无人机数据评估覆盖种植对有机种植的白色葡萄园品种（例如“Pedro Ximénez”）农艺和酿酒参数的影响。
