Abstract
The aim of the study was to find the antioxidant activity and enzyme activity of catalase and peroxidase of vegetable plants. The results indicated that the use of seaweed liquid fertilizer can enhance the antioxidant activity of Solanum melongena L., Lycopersicon esculentum Mill., Capsicum annuum L., Brassica oleracea var. Capitata L. and Allium cepa L. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays were used to determine the antioxidant properties of seaweeds by measuring the decrease in absorbance at 517 nm. The DPPH activity was highest in brown seaweed liquid fertilizer. This study implied that impacts on vegetable plantlets by seaweed liquid fertilizer extracted with enzymes is better in brown seaweed liquid fertilizer as compared to control.
