The effect of seaweed liquid fertilizer (SLF) of Caulerpascalpelliformis was tested at different concentrations (5, 10, 25, 50, 75, and 100%) on growth and biochemical, and enzymatic activity of Abelmoschusesculentus. The seaweed extract was found effective in increasing the biomass growth of shoot, root length fresh, dry weight pigmentation of chlorophyll-a,b and carotenoids. The biochemical tested like protein, amino acids. The enzymatic activity like, α, ß amylase, catalase, peroxidase, polyphenol oxidase. The finding of the present study and biochemical, enzymatic activity than that of higher concentration.
