This study used Completely Randomized Design (RAL) with 6 treatments and 4 replications. Parameter observed was Plant height (cm), Number of Leaves, Leaf Area (cm), Wet Weight (g), and Dry Weight (g). The data was analyzed using the Analysis of Variants (ANOVA) test and DNMRT further test at 5% level. The result showed liquid organic fertilizer of Sargassum sp. had no significant effect on plant height, number of leaves, leaf area, fresh weight and dry weight of spinach plant (Amaranthus hybridus L.).
