STATISTICAL ANALYSIS OF ECONOMIC INDICATORS IN NITROGEN FIXATION OF BIRD'S FOOT TREFOIL CULTIVARS AND ITS INFLUENCE ON THE ECOLOGICAL EFFECT
Bibliographic record
Abstract
The amount of fixed nitrogen per decare was studied in the experimental field of Research Institute of Mountain Stockbreeding and Agriculture-Troyan of bird'sfoottrefoil cultivars, such as Targovishte , Alvena, Lotanova and Frilo (Italy), Polom (Slovakia), Bonnie (France), Bull (Canada). The Lotanova and Polom varieties have increased nitrogen-fixing capacity and level of tuber formation, as well as fixed nitrogen per decare ( 7.40 and 7. 7 N fix, kg/da), which is a prerequisite for increasing soil fertility and the ecological effect. These two varieties could be recommended as suitable for implementation in production from an economic and ecological point of view. The correlation analysis proved a high positive correlation dependence of gross revenue with yield (r=0.9999), production costs (r=0.9982), and the amount of fixed nitrogen (r=0.9998). Plant nitrogen storage through symbiotic nitrogen fixation of bird'sfoottrefoil, as a suitable meadow legume species for mountain conditions, determines its ecological effect.

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.
