Growth of Cicer arietinum With Azotobacter vinelandii and Burkholderia vietnamiensis Endophytes of Leucaena leucocephala and 50% NH4NO3
Bibliographic record
Abstract
Agricultural production of Cicer arietinum demands, the use of nitrogen fertilizer as NH4NO3, its excessive application causes the loss of soil productivity and global warming by releasing N2O. An ecological to solve this problematic condition could be: to isolate endophytic bacterial genera that promote plant growth such as: Azotobacter vinelandii and Burkholderia vietnamiensis, from Leucaena leucocephala a wild plant able to face nutritional environmental, that allow reducing and optimizing the dose of NH4NO3 at 50%, non-compromising healthy plant growth of C. arietinum. Therefore, the objectives of this work were: i) to isolate of endophytic genus of A. vinelandii and B. vietnamiensis from L. leucocephala, ii) to analyze the effect of A. vinelandii and/or B. vietnamiensis on growth of C. arietinum at 50% NH4NO3, iii) to identify A. vinelandii and B. vietnamiensis based on the biochemical profile. The isolation of A. vinelandii was in Burk agar and B. vietnamiensis on PCAT. The results showed that A. vinelandii and B. vietnamiensis isolated from L. leucocephala were beneficial to the healthy growth of C. arietinum by increasing the germination percentage and reducing the emergence time while both the phenology and biomass of C. arietinum were positively affected by 50% NH4NO3; based on the conversion of organic compounds in the root into phytohormones by A. vinelandii and/or B. vietnamiensis better when inoculated as a mixture than individually with numerical values that were statistically different by ANOVA-Tukey (P < 0.05), compared to the same numerical variables of C. arietinum growth with 100% NH4NO3 uninoculated, used as a relative control. While it was found that A. vinelandii showed a biochemical profile of this genus and species with cyst production while B. vietnamiensis had the biochemical profile of this genus and species. The above supports the idea that L. leucocephala is an important source of plant growth-promoting endophytic bacteria for sustainable agriculture without damaging the soil or generating N2O to mitigate due to conventional agriculture production of C. arietinum.

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.
