Abstract

fetched live from OpenAlex

Abstract The experiment was carried out at Daquq Research Station, Kirkuk Governorate during 2018-2019 to evaluate solid set sprinkler irrigation indicators in the cultivation of flax varieties. The studied flax traits included plant height, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, weight of 1000 seeds, seed yield per plant, biological yield per plant, harvest index, and seed yield per hectare. The results showed that the highest genetic correlation was between stem diameter and seed yield, reaching 2.89 under the Canadian sprinkler head. The highest environmental correlation was observed between the number of main branches and seed yield, reaching 3.50 under the Turkish sprinkler head. The highest phenotypic correlation was between oil percentage and seed yield, reaching 2.38 for the Canadian sprinkler head. Regarding the path coefficient analysis, the Canadian sprinkler head showed the highest direct effect on the harvest index, reaching 0.7136. It also had the highest total effect through the oil-to-seed ratio, which reached 2.7173. For the trait of number of days to 50% flowering, the direct effect was 0.9996. In the interaction experiment between study factors, the highest direct effect was found through the oil-to-seed ratio, reaching 0.8580, with the highest total effect on the oil-to-seed ratio summing up to 1.2849.

Not 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.
