Physiological response of dry bean to residue management
Bibliographic record
Abstract
The effect of residue management on dry bean (Phaseolus vulgaris L.) height, maturity, and yield was studied at two sites in Saskatchewan in 1999. Treatments were spring cultivated, mowed or unaltered prior to seeding. Preliminary results indicate no effect of residue management on maturity of either cultivar. Tillage reduced emergence in cultivated treatments compared to no-till, possibly by causing compaction, reducing macroporosity and creating conditions suitable for root diseases. Plant density differences largely determined yield, biomass at physiological maturity, and pod clearance. Yields were 682 kg/ha, 838 kg/ha, 880 kg/ha for cultivated, mowed and stubble respectively. Plant height was not significantly affected by tillage. Bean pod clearance under conventional tillage was 5% higher than under no-till, regardless of stubble height, possibly because of the lower plant density in cultivated treatments. Differences among treatments for internode length (Fig. 2a and b) were not statistically significant. Direct seeding of dry bean appears to be feasible.

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.
