Abstract

fetched live from OpenAlex

Alfalfa (Medicago saliva L.) is a perennial legume that is widely utilized for hay, pasture, haylage, and green manure in the United States and Canada. Inclusion of alfalfa in grazing lands in the Northern Great Plains has been an interest for many years. However, persistence of alfalfa under grazing can be poor, especially when harsh environemental conditions contribute additional stress. Demand exists for alfalfa that can establish and persist in semiarid grazing lands. A naturalized population of predominantly yellow-flowered alfalfa (Medicago saliva L. subsp ..falcata [L.] Arcang.) exists in the Grand River National Grassland in northwestern South Dakota. Increased use of this alfalfa in agricultural production systems has the potential to provide sustainable benefits. Few studies have evaluated persistence and performance of naturalized yellow-flowered alfalfa in comparision with other alfalfa populations. Contemporary research about interseeding naturalized yellow-flowered alfalfa in semiarid grazing lands is also needed. Our objectives were: I) to determine the suitability of yellow-flowered alfalfa populations for pasture use in the Northern Great Plains, and 2) to evaluate the effect of seeding date, sod suppression, and seeding rate on initial establishment of yellow-flowered alfalfa interseeded in crested wheatgrass [Agropyron cristatum (L.) Gaertn.]. Research was conducted in the Northern Great Plains to address these two objectives. Research results revealed that yellow-flowered alfalfa populations are persistent under a wide variety of stresses including mob grazing and ice sheets. Initially establishing yellow-flowered alfalfa in crested wheatgrass stands is possible. However, growing conditions (e.g. precipitation) appear to have a greater influence on initial establishment than seeding date, sod suppression, and seeding rate. This thesis is intended to provide the reader with relevant information about yellow-flowered alfalfa research conducted from 2006 through 20 l 0. The author encourages future research that would expand on the studies described in this thesis.

Teacher imitation

Not 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.
