Effect of Italian Ryegrass Establishment Methods of Yield, Herbage Quality and Soil Compaction
Bibliographic record
Abstract
Italian rye grass (Lolium multiflorum Lam.) is a summer annual in the Atlantic Provinces of Canada and reseeding in spring is necessary for maintaining productive swards. Intensive cultivation and seeding method of Italian ryegrass was compared with four direct seeding techniques in four three-year experiments on a Charlottetown fine sandy loam soil, at two sites, on Prince Edward Island. Dry matter yields of ryegrass were similar for direct seeding and seeding cultivated seed bed for the first two years. Some yield advantage was recorded when direct seeded ryegrass followed barley in the third year. Total nitrogen concentration in tissue was similar for all treatments in the first year, but in the second and third years total N was generally greater with cultivation than with direct seeding. Although dry matter yield of permanent pasture was greater than that of ryegrass the nitrogen produced ha-1 was similar for both. Measurements of soil resistance, porosity, proportion of macro-pores (diameter> 50 µ,m) and pore continuity, used as indices of soil compaction, did not show any adverse effect of the seeding methods on soil structure.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
