Abstract:

Optimum seaweed growth by using inorganic fertilizers is not a wise move considering the recent increase in consumers who want products that are free of pesticide residues and artificial fertilizers. The purpose of this study was to analyze the optimal dose of vermicompost fertilizer to produce daily specific growth rates and best G. verrucosa seaweed biomass production. From the results of the study it was found that the higher dose given would result in the highest daily specific growth rate (SGR) and the highest biomass production compared to the treatment without the application of vermicompost fertilizer (control). From the statistical analysis of normality test, homogeneity of SGR and Biomass Production showed the distribution of normal and homogeneous data, then for ANOVA test showed that the treatment of vermicompost fertilizer gave significant effect (p<0.05) to SGR and Biomass Production. The highest SGR was obtained at treatment A (dose 300 g /m3) of 2.75%/day and the lowest in treatment F (control) of 1.63%/day. The highest biomass production was obtained at treatment A (dose 300 g/m3) of 109.17 g and the lowest in treatment F (control) was 49.7 g.
