Agronomic performance and quality of spring wheat and soybean cultivars under organic culture
Bibliographic record
Abstract
Abstract Spring milling wheat (Triticum aestivum L em. Thell) and soybean (Glycine max L.) cultivars were managed to International Organic Certification Standards on two organically certified farms to evaluate two physical weed control methods, cultivar performance and quality. Nutrients were supplied as manure and compost. There was no difference (P<0.05) between flaming plus fingerweeding versus fingerweeding twice, 10 days apart, on weed control, yield, and protein in both crops. The spring wheat cultivar, AC Barrie, may be particularly well suited to production under an organic system, as indicated by its superior performance to AC Walton at the Springfield site in 2000, when growth conditions were favorable. A severe drought in 2001 limited the mineralization of soil and manure nitrogen, with the result that all spring wheat cultivars at the Springfield site did not make 13.5% grain protein, required to meet milling quality criteria. Also, in 2001 at both sites, soybean yields were reduced by 50% compared to 2000 because of reduced moisture availability and weed competition. Delays in field operations, lack of sufficient soil moisture and reduced mineralization of manure during the 2001 growing season were major factors in influencing crop production, especially at Springfield.

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.
