Salinity Tolerance of Turf and Forage Grasses
Bibliographic record
Abstract
There are over 1.2 million ha of cultivated saline land in the province of Alberta, Canada. Our experiment's objectives were to develop reliable recommendations under field conditions of the salinity tolerance of various grasses. Information on how salinity levels influence the growth of grasses under field conditions would provide better management options for forage production. An irrigated site was established at Brooks and a dryland site at Hanna, Alberta. Twenty-five species are being evaluated under irrigation and I 9 under dry land using a randomised block design, Forage yields indicate that tall wheatgrass (Elytrigia pontica), Dahurian wildrye (Elymus dahuricus) and Russian wildryc (Psathyrostachys juncea) have a high degree of salinity tolerance under irrigation. Under dry conditions pubescent wheatgrass (Elytrigia illlermedia ssp. trichophora) and weeping alkaligrass (Puccinellia distans) were the most saline tolerant. Turfgrass species such as tall fescue (Festuca arundinacea) and creeping red fescue (Festuca rubra) showed good-to-moderate tolerance to salinity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
