Abstract

fetched live from OpenAlex

L’objectif était d’évaluer le potentiel agronomique, soit l’établissement, la survie hivernale, la production de biomasse et la valeur nutritive de nouvelles espèces fourragères riches en tanins condensés ou en lactones sesquiterpènes cultivées en semis pur et en association avec deux graminées fourragères, la fléole des prés (Phleum pratense L.) et la fétuque des prés (Festuca pratense Huds.), et ce, en gestion de pâturage dans quatre régions climatiques du Québec. L’expérience au champ s’est déroulée aux stations de recherche de Sainte-Anne-de-Bellevue (Montréal), Saint-Augustin-de-Desmaures (Capitale-Nationale), La Pocatière (Bas-Saint-Laurent) et Normandin (Saguenay-Lac-Saint-Jean), pendant deux années (2016 et 2017). Sur l’ensemble des stations en 2017, la chicorée (Cichorium intybus L.) et le lotier corniculé (Lotus corniculatus L.) ont eu des rendements satisfaisants comparés à celui de la luzerne, et ce, à tous les sites, alors que le sainfoin (Onobrychis viciifolia Scop.) a moins bien performé. Le sainfoin avait des teneurs en tanins condensés (moyenne de 10,7 g kg-1 MS) et en protéines moyennement et lentement dégradables dans le rumen les plus élevées.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
