Abstract

fetched live from OpenAlex

O objetivo deste trabalho foi comparar o potencial do trigo irrigado em sistemas de plantio direto e convencional, bem como avaliar o desempenho de quinze cultivares de trigo nos dois sistemas de produção, em sucessão a soja, na região do sul de Minas Gerais. O experimento foi conduzido na Universidade Federal de Lavras (UFLA), em Lavras, MG, nos anos de 2006/07 e 2007/08, utilizou-se o delineamento em blocos casualizados em faixas com três repetições. Nas faixas foram instalados os sistemas de cultivo (convencional e plantio direto) e, nas parcelas, foram distribuídas as quinze cultivares de trigo. Foram avaliados rendimentos de grãos e dados agronômicos das plantas de trigo. O sistema de plantio direto proporcionou incremento médio de 25 % nos teores de matéria orgânica na camada superficial do solo em relação aos teores iniciais e ao cultivo convencional indicando o potencial do sistema em melhorar a qualidade do solo. As cultivares testadas, independentes dos anos agrícolas, alteraram significativamente os rendimentos de grãos e as características agronômicas avaliadas. As altas produtividades apresentadas pelas cultivares avaliadas neste estudo, indicam o elevado potencial da cultura do trigo irrigado em sucessão a soja, para as condições clima e de solo similares ao utilizado neste estudo.

Not 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.
