Abstract
The objective of this study was to evaluate the residual effect of the gypsum when used with phosphate fertilization on the mineral nutrition, development and yield of second corn crop. The experiment was conducted at UFJ, with an experimental design consisting of 15 treatments established in randomized blocks in a 5 × 3 factorial scheme, with 4 replicates. The first factor corresponded to doses of gypsum (0, 1, 2, 4 and 8 Mg ha-1) and the second factor corresponded to doses of phosphorus (0, 40 and 80 kg ha-1). 16 months after the application of the various doses and treatments of agricultural gypsum, the following components were evaluated: dry root mass, macro and micronutrient contents in the leaves, production components and grain yield. The residual effect (16 months) of gypsum did not increase efficiency of phosphate fertilization for second corn crop. Under water stress conditions, the yield of corn grains responds to the application of agricultural gypsum above that of the dose recommended by the formula NP = 5 × g kg-1 of clay, which for this research is 2.93 Mg ha-1 of gypsum. Phosphorus provides increases in corn grain yield only when 100% of the recommended dose is applied.

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
