Management Requirements for Dryland Creeping Bentgrass Seed Production
Bibliographic record
Abstract
An extensive research project was initiated in 1992 to develop a dryland seed production system for creeping bentgrass (Agrostis stolonifera L.) in western Canada. Two objectives involved determining the appropriate renovation method and spring nitrogen timing and rate to maximize seed yield. Renovation experiments included scalping, mowing, aeration, tillage, burning and chemical and mechanical gapping and spring N fertilization experiments included at 0, 50, 100, and 150 kg N ha-1 at two dates. Scalping (removal of stubble and growth to 1.25 cm) showed the greatest potential to maintain seed yields. Timing of renovation was also important with early (after harvest) treatments superior as they allowed an adequate regrowth period prior to winter. Spring nitrogen applications of greater than 50 kg ha-1 did not show increased seed yields. Dryland seed production is possible in the higher rainfall areas of western Canada with yields ranging from 50 to 500 kg ha-1, but attention to recommended management practices is essential given the short growing season.

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.
