Abstract

fetched live from OpenAlex

A cana-de-açúcar possui grande importância econômico-social e política para o Brasil. Este trabalho teve como objetivo avaliar o efeito de doses e fontes de manganês nessa cultura. O experimento foi realizado no sítio Fujimoto, área administrada pela Destilaria Vale do Paraná S/A Álcool e Açúcar, no município de Suzanápolis, SP. O delineamento experimental utilizado foi o de blocos ao acaso no esquema fatorial 5 x 3, sendo cinco doses de Mn (0; 2,5; 5,0; 7,5; e 10,0 kg ha-1) e três fontes (quelato, FTE e sulfato de manganês), aplicadas no sulco de plantio, em quatro repetições. As parcelas foram constituídas por quatro linhas de 5 m de comprimento e espaçadas 1,5 m. A variedade de cana-de-açúcar utilizada foi a RB 86-7515, realizando-se dois cortes. As fontes de Mn proporcionaram semelhantes produtividades de colmos, tanto da cana-planta quanto da primeira cana-soca. O quelato de Mn proporcionou maior número de colmo por metro de sulco na cana-soca. As doses de Mn não influenciaram a produtividade de colmos da cana-planta e da cana- soca, porém aumentaram o número de internódios e o diâmetro de colmo na cana-planta até as doses de 6,9 e 6,6 kg ha-1 de Mn, respectivamente.

Full frame distilled prediction

Teacher imitation

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.
