Track: Sustainability and Green Systems

Abstract

This study aims to provide a basis for households that relates the effectiveness of sustainable fertilizers to the vegetation growth of sweet potatoes. The proponents analyzed the vegetative growth results of sweet potato using 100g, 200g, and 300g of eggshells and 158g, 316g, and 474g of rice husks, comparing it to commercially available urea fertilizer with 11.34g and no fertilizer. The factors used to measure sweet potatoes’ vegetative growth were Vine Length, Leaf Length and Width, and their overall acceptability through taste test surveys. Using the Kruskal-Wallis Test and ANOVA Single Factor, results showed that the highest amount of Eggshell and Rice Husk fertilizer, 300 g and 474 g, respectively, produced the highest mean value of leaf and width, as well as vine length. However, among the four fertilizers, there is no statistically significant difference in the overall vegetative growth of the sweet potato. Also, in the sensory evaluation, results suggest no statistically significant difference in using any fertilizers on the color, taste, aroma, mouthfeel, and overall acceptability of the Sweet Potato Tops. However, the Kruskal-Wallis tests indicate urea fertilizer has the highest rating regarding mouthfeel and overall acceptability. Finally, the Eggshell, Rice Husk, and no fertilizer received the highest mean rating in color, taste, and aroma. With this, the proponents recommend studying the right and proper usage of Urea Fertilizer to ensure its safety and effectiveness as it had the most favorable results.
