Abstract
During 1995 and 1996, experiments with globe artichoke (Cynara scolymus L.) were conducted in southwestern Quebec (lat. 45° 26 'N long. 73° 56 'W) to determine the optimum nitrogen fertilizer requirements and irrigation levels and to evaluate two widely grown cultivars for their suitability to Quebec regions. In order for flowering to occur plants must undergo a vernalization period. In 1995, plants received 32 chilling hours, an amount sufficient for 89 % Imperial Star plants and 39 % of Green Globe Improved to produce buds. In 1996, plants received 72 chilling hours, an amount sufficient for 94% of Imperial Star and 81 % Green Globe Improved plants to flower. Imperial Star produced 3 marketable lateral buds per plant compared to 2 buds per plant for Green Globe Improved in 1995. Both cultivars in 1996 produced 2 marketable lateral buds per plant. The average bud weight was higher for both cultivars in 1996 compared to 1995. Total yield was significantly higher with regular irrigation compared to variable irrigation. Nitrogen applications above 100 kg N/ha did not significantly increase weight of buds in both years suggesting that that this amount was sufficient for our culture situation. Imperial Star appeared to be a significant improvement over Green Globe Improved plants grown from seed.

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 it
