Brown seaweed, Turbinaria conoides, has been used as food since ancient times and is more popular in Asia than in Europe and North America. In terms of antioxidant, antiinflammatory, antibacterial, and anti-cancer actions, they possessed a variety of biological potentials. The T. conoides shadow dry powder was combined in a 1:20 (w/v) ratio with distilled water to create the seaweed liquid fertiliser (SLF), which was then heated to 70°C for an hour. Using UV-Visible and FTIR spectroscopy, SLF was employed to investigate their impact on avarai and black soya bean seed germination and phytochemical analyses. The greatest absorption peaks were found in the qualitative UV-Visible spectra to be at 200, 224, 231 and 300 nm. By using UV-VIS spectroscopic examination, it was confirmed that flavonoids were present in the SLF. The results of an FTIR analysis showed that a peak at 3351.6 cm-1 indicated the presence of O-H stretching, a peak at 1630.1 cm-1 suggested C=O vibration, a peak at 1022 cm-1 indicated inorganic ions such silicate ions, and a peak at 654.66 cm-1 indicated C-Br and C-I stretch, respectively. The percentage of seeds that germinated in the control experiment ranged from 40 to 44 percent. Germinated seeds treated with SLF yielded 72 and 84 percent at 100% of SLF concentration in avarai and black soya bean seeds, respectively. The SLF-treated seeds grew twice as quickly as the untreated seeds. Compared to avarai seeds, SLF more successfully promotes black soya bean seeds. The growth rate of germinated seeds was measured on the seventh day and quantified in terms of cm shoot and root growth, showing a similar tendency to that of seed germination. The SLF-treated seeds grew twice as quickly as the untreated seeds. SLF more successfully promotes avarai seeds than black soya bean seeds
