Phosphorus Adsorption Capacity of Four Soil Series for P Requirement of Wheat (Triticum aestivum L)
Bibliographic record
Abstract
A pot experiment was conducted in order to know the phosphorus requirement of wheat as affected by different levels of phosphorus (P) for obtaining 95% relative yield grown in four soil series i.e. Gishkori, Buzdar, Sultanpur and Tikken of Dera Ismail Khan Khyber Pakhtunkhwa, Pakistan. The various treatment levels were consisted of 0, 5.5, 11.0, 16.5 and 22.0 mg P/kg of soil. Wheat dry matter yield remained at highest (1.1g) where P was supplemented at 22.0 mg P/kg in Gishkori and lowest (0.95g) in Tikken soil with the same P applied level. An increase in phosphorus concentration was recorded in wheat shoot with an increase in applied P level. Maximum phosphorus percentages recorded in wheat were 0.28 and 0.26 grown in Gishkori and Buzdar soil series followed by Sultanpur and Tikken with values of 0.11 and 0.10 respectively against P applied level of 22.0 mg P/kg soil. Minimum P concentration was noted in control. The phosphorus content of wheat and P levels were highly correlated with r values of 0.99. 0.99. 0.98 and 0.74 for Gishkori, Buzdar, Sultanpur and Tikken soil series respectively.

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.
