Nutrient concentrations and nutritive value of field pea (<i>Pisum sativum</i> L.) straw in south central Alberta
Bibliographic record
Abstract
The development of field pea as a major specialty crop in western Canada has led to questions regarding the nutritive value of its straw component. The objective of this study was to examine the nutrient composition of field pea straw collected from south central Alberta variety trials. Our analysis focused on four varieties grown on four locations for the period between 1995 and 1997. Five nutrients were examined: CP, Ca, P, ADF and NDF. There were significant year × location interaction effects for concentrations of all five nutrients. Location-to-location differences were considerably inconsistent across the years. The environmental variation in nutrients of pea straw requires that the optimal strategy of managing the pea straw (particularly using it as part of cattle feed) be based on an extensive sampling of the straw over diverse environments rather than on the average value. Key words: Nutritive composition, field pea straw, environmental variation, Pisum sativum L.

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.
