Abstract
Soil tillage carried out in total area in sugarcane field reform causes changes in soil structure, affecting root system development due to the use of agricultural machinery from planting to harvesting. Thus, we assessed the growth and stalk productivity of sugarcane cultivated in an Oxisol and Ultisol submitted to chiseling in the planting row and in total area. The experiment was conducted in two agricultural areas in a large paired-plot design. Treatments consisted of two areas submitted to chiseling in the planting row (CPR) and chiseling in total area (CTA) in an Oxisol and Ultisol. The variables number of tillers, number of green and dead leaves per plant, leaf area, leaf area index, plant height, and total dry matter were measured during six assessments over the crop cycle sugarcane planting with the variety CTC 14 in the Oxisol and with the variety CTC 4 in the Ultisol. In addition, stalk productivity was assessed after harvesting. The assessments were performed at 1071, 1705, 2388, 3600, 4593, and 5764 accumulated degree-days (ADD) in the Oxisol and at 821, 1519, 2294, 3570, 4562, and 5754 ADD in the Ultisol. Soil tillage with CPR can be replaced by CTA since growth and stalk productivity of sugarcane were similar regardless of the location of the chiseling operation.

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
