A Study of Some Seed-Borne Diseases of Cereals in Canada: III. Effect of Rate of Seeding, Percentage of Infested Kernels, and Weeds, on the Yield of Plots Sown with Treated and Untreated Seed1
Bibliographic record
Abstract
Field-plot experiments with wheat seed naturally infested with Helmintho-sporium sativum P K. & B, oat seed infested with H avenae Eidam, and barley seed infested with either H. sativum or H. teres Sacc, showed that in plots kept free from weeds the percentage of infested kernels in the seed affected the percentage germination but had little or no effect on the yield As a consequence, treatment of the seed to improve its germination also had but little or no effect on the yield. Further experiments with practically disease-free wheat seed indicated that these results were due to a compensation for low germination by an increased tillering of the plants that survived, and therefore the yield of plots with thin stands was but little different from the yield of plots with dense stands However, when Argentine rape (Brassica napa L ) was sown along with the grain to simulate “weediness” in the experimental plots, the compensation for low germination by increased, tillering was largely prevented, and the 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.
