The effect of different concentrations (20%, 40% 60%, 80% and 100%) of seaweed liquid fertilizer (SLF) of Sargassum wightii on the growth and biochemical characteristics of Abelmoschus esculentus was studied. The low concentration (20%) of S. wightii extract promoted the shoot length, root length, fresh weight, dry weight, chlorophyll, carotenoid, protein, amino acid, reducing sugar, total sugar, α-amylase and β-amylase activities in Abelmoschus esculentus.
