Yields of willow biomass crops across a range of sites in North America
Bibliographic record
Abstract
Yield is an important factor in determining the economic feasibility of willow biomass crops. Over the past 18 years a series of yield trials have been established across North America with older clones from the Ontario Ministry of Natural Resources and the University of Toronto and new genotypes from the SUNY-ESF breeding programme. One trial that has been harvested four times showed that the yield of four commercial clones increased by 23.0 % from the first to second rotation and by 30.8 % from the first to fourth rotation. Quantifying these changes is important when modeling production and cash flow of these perennial systems. Across all yield trials, those with new willow clones have produced 38 % more biomass than trials with the older clones. The top three new clones in each of the nine trials that have been harvested produced a mean yield of 11.5 odt ha-1 yr-1, which was 13.9 % better than the three older reference clones in these trials. Key words: Breeding, Salix, short rotation woody crops, yield

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.
