Abstract

In the 21st century, the increased farming activities have harmed both ecosystems and agricultural systems on Earth. This is because of the misuse of mineral fertilizers and toxic plant protection products. To obtain the “elicitor” extract, rhizobacteria were grown in a thermostat for 3 days and then subjected to autoclaving at a temperature of 120°C and 1 atm. for 20 minutes. Azospirillum, Azotobacter, and Pseudomonas are the three most significant growth-promoting bacteria. These organisms influence plant growth regulators, including auxin, gibberellin, and cytokines, in addition to biological nitrogen fixation and soil phosphate solubilization. The research mentions that Azotobacteria create antifungal substances that fight against plant infections, boost seedling viability and germination, and, as a consequence, enhance plant development in general. The result presented that the fifth peak at 10.525 minutes showed the presence of 4(dimethylamino)-α-(P-toluidine) benzylphosphine oxide at 16.0%. The sixth peak at 10.728 minutes contained 19.48% of quinoline-3-carbonitrile, 4-methyl-2-dimethylaminomethylamino, while the seventh peak at 11.177 minutes contained 41.8% of ethanediol % 2 C+bis(phenylhydrazone).
