Abstract

fetched live from OpenAlex

Six yield trials were carried out in Ponte Nova, MG, .to verify the behavior of 12 cultivars of rice beans. Trials were installed on the following dates: March 18, April 16, April 30, August 4, November 17, and December l9. Fifteen to twenty seeds were planted in rows 0.5 m apart. Sprinkler irrigation and insecticide were used when necessary. Rice beans took 6-9 days to emerge from soil. Life cycles (emergence to harvest) varied from 82 (December 19) to 121 days (April 30). No foliar disease was observed on the plants. Average trial yields ranged from 1,234 {December 19} to 1,993 kg/ha (March 18). Yields over 2,000 kg/ha were attained only in trials installed on March 18 and April 30. Maximum yield was achieved with cultivar E-37 (2,276 kg/ha) in the April 30 trial. In general, cultivar yields were similar. Average 100-seed weight of cultivara varied from 6.9 to 9.0 g.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
