Components of Maize Crop as a Function of Doses of Polymerized Urea
Bibliographic record
Abstract
The efficiency of nitrogen fertilizer applications such as urea is reduced as a function of volatilization and leaching losses. For this reason, the producers have opted for the use of polymerized urea. Therefore, the objective of this work was to evaluate the production components in maize culture as a function of doses of polymerized urea. The experimental design was a 5 × 3 factorial, totaling fifteen treatments, corresponding to five doses Polyblen® 39% N of polymerized urea (0, 250, 500, 750 and 1000 kg ha-1) and three cultivars of maize (30A37, MG580 and MG600). The variables were analyzed after harvest, being: plant height, ear height commercial, stem diameter, leaf area, plant leaf area, ear diameter without husks, ear diameter with husks, ear length without husks, ear length with husks, number of grains per row, number of grains per ear, grain yield, number of rows per ear, 100-grain weight. Regarding the production components in the corn crop, the presence of Polyblen® polymerized urea influenced all variables analyzed. While varieties 30A37, MG580 and MG600 demonstrated a significant increase in their productivity averages.

How this classification was reachedexpand
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.
