Phenological and Growth Interactions between Velvetleaf (Abutilon theophrasti M.) and Cotton (Gossypium hirsutum L.)
Bibliographic record
Abstract
The phenology and growth of A. theophrasti in competition with cotton, and the influenced of weed sowing time andweed plant density on phenology and growth were examined in several field studies conducted over the period2000–2002. A. theophrasti was found to produce three cohorts that emerged in a staggered manner from April 21 toJune 20. The first cohort emerged simultaneously with cotton under a plastic cover and the second by the time cottonplants had 5–6 true leaves. Flowering in these two cohorts started at 572–594 growing degree-days (GDD), bollripening (stage H) at 800–885 GDD and boll drying at 1020–1037 GDD.Velvetleaf and cotton cotyledons were formed simultaneously at all weed sowing densities. Also, plant height of A.theophrasti increased with increasing density, whereas cotton height decreased due to shad and competition.

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.
