Re-visiting use of <i>Penicillium bilaii</i> with phosphorus fertilization of hard red spring wheat
Bibliographic record
Abstract
Penicillium bilaii is a fungus that lives in association with plant roots and has been shown to increase phosphorus (P) solubility and uptake by some crops. A series of 47 experiments with hard red spring wheat (Triticum aestivum L.) that were carried out in the three prairie provinces between 1989 and 1995 and included treatment with P. bilaii as a main plot (with or without) and four rates of fertilizer P (0, 4.4, 8.7 and 13.1 kg P ha-1) as subplots were statistically analyzed to ascertain whether use of P. bilaii resulted in increases in both yield and P uptake by wheat. Of the 47 experiments, response to fertilizer P was obtained in 33 experiments and to P. bilaii in 14, in five of which the response was positive and nine resulted in yield decreases. These responses could not be attributed either to extractable P soil concentration, soil organic matter (SOM) or texture, or weather conditions and are considered random events. Overall, P uptake was a function of fertilizer P rate only.Key words: Seed-treatment, seed yield, P uptake, P use efficiency

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.
