Abstract

fetched live from OpenAlex

Corn is one of the major crops of North America. It is one of the major source of food for both humans and livestock. Water and nitrogen are two important components that affect the yield of all crops. This study looks at the total water use of the plant under different nitrogen application. Nitrogen was applied at the rate of 125, 180 and 245 kg/ha. The different water table management system maintained were water table at 60 cm from the soil surface with the help of sub-irrigation and free drainage plots with variable water table as determined only by rainfall. The soil type was sandy-loam. The study was conducted in 2008 and 2009 on a farm at Coteau-du-lac, 40 km west of Montreal.

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.
