Abstract

fetched live from OpenAlex

Yellowhead is a cultivar of alfalfa (Medicago sativa L. Subsp. falcata). Yellowhead was selected at the Semiarid Prairie Agricultural Research Centre, Agriculture and Agri-Food Canada (AAFC), Swift Current, SK, and developed through the collaboration of Research Centres of AAFC in Saskatchewan. Yellowhead is a “falcata type”, i.e., yellow flowered with sickle shaped seed pods, with about 60% of the plants displaying the rhizomatous characteristic. Yellowhead is moderately resistant to bacterial wilt and particularly tolerant of competition in mixed swards with grass and under heavy grazing. The herbage yield of Yellowhead was not significantly different from that of the parent population, ScMf 3713 and check cultivars in trials conducted on dryland near Swift Current, Saskatchewan.Key words: Cultivar description, winter hardiness, persistence, grazing tolerance

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
