The seaweed is one of the important growth promoting hormonal effects on crop plants which has been proven for many decades.  Some of the plant hormones have been recorded in seaweeds such as IAA, IBA and cytokinins along with minerals and vitamins. Seaweed liquid fertilizer has been shown to have a wide range of beneficial impacts. In the present study, the effect of different concentrations of (SLF 0, 0.5, 1.0, 1.5 and 2.0%) and (SLF + CF 0.5, 1.0, 1.5 and 2.0%) Seed germination, photosynthetic pigments, fresh and dry weight, and shoot and root length were all measured on a treated groundnut plant. The results found a gradual increase of seedling growth and photosynthetic pigments at increasing concentrations, however, higher concentrations 1.0 and 1.2 per cent were decreasing trends in groundnut plants.
