Abstract

fetched live from OpenAlex

The use of annual ryegrass (Lolium multiflorum Lam.) as a winter cover crop and grazing option in the Southeast Unit-ed States has become a common practice. Recent research evaluating the effects of seeding time on seed yield in Canada determined autumn seeding produces the most desired results relative spring seeding, but indicated that varied autumn seeding rates would further their findings (Coulman et al. 2013). A University of Arkansas study utilized cool season annuals, wheat (Triticum aestivum L.) and annual ryegrass, to evaluate animal performance and seeding date effects. This research indicated that seeding cool-season annuals in early September may result in greater autumn forage production relative late October seeding. (Coffey et al. 2013). While current recommendations in the Southeast United States are to plant annual ryegrass in early autumn, differences among dates and locations have not been evaluated to maximize yield and provide the best forage utilization for producers. The objective of the study is to develop extension recommendations for autumn date seeding of annual ryegrass for maximum seasonal yield potential.

Full frame distilled prediction

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.
