EFFECTS OF NITROGEN ON REPRODUCTIVE DURATION AND YIELD IN LENTIL CULTIVARS
Bibliographic record
Abstract
Reduced nitrogen (N) uptake and N2 fixation during the reproductive growth may reduce the yield in lentil. Five cultivars were grown in two soil media and four N treatments of an inoculated control (NI), and receiving N until flowering (NF), podding (NP) and maturity (NM) in Saskatchewan, Canada. The NF treatment produced the lowest yield, and plants relying on fixation grew larger and yielded more. But NI produced less growth and yield than NP and NM plants, demonstrating that N2 fixation needed improvement for maximal yield. The NP treatment produced the highest yield and more efficiently used N than the later N application in NM. Nitrogen applied at and after mid-pod extended the days to maturity by increasing the reproductive growth period and post-flowering vegetative biomass. Current lentil cultivars require N supply up to at least the mid-pod stage, although the exact stage and timing of N supply need refinement.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
