Photosynthetic resilience of dry-farmed 'Pedro Ximénez' grapevines under organic versus conventional management in a warm Mediterranean vineyard.
Article in Journal of the science of food and agriculture, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOrganic viticulture is expanding across Mediterranean wine regions, driven by EU sustainability policies and increasing consumer demand. However, comparative studies assessing both physiological performance and productivity of grapevines under organic and conventional management while maintaining similar soil and climatic conditions remain limited, particularly in dry-farmed warm Mediterranean environments. This study evaluated the physiological and agronomic responses of the grapevine cultivar 'Pedro Ximénez' over two consecutive seasons (2022-2023) in a commercial dry-farmed vineyard in south-western Spain managed under certified organic and conventional management systems.

conclusionUnder the conditions of this commercial, warm Mediterranean vineyard, organic management was associated with reduced seasonal stomatal stress while maintaining comparable productivity, suggesting that organic viticulture may represent a viable strategy for dry-farmed vineyards in warm Mediterranean regions. © 2026 Society of Chemical Industry.
