Eggshells, garden soil, organic fertilizer, scallion plants, wood ash


This study intended to evaluate the growth of Scallions (Allium fistulosum L.) using eggshells and wood ashes as organic fertilizer. It aims to assess and determine the best possible (optimal) fertilizer material combination that is compatible with the growth performance of scallions using eggshells and wood ashes. Four different treatment combinations were considered in this study as follows: T1 (consisting of 100% garden soil), T2 (consisting of 75% garden soil, 25% wood ash), T3 (consisting of 75% garden soil and 25% eggshells) and T4 (consisting of 70% garden soil, 15% wood ash, and 15% eggshells). The height and number of leaves per experimental unit were gathered as the variable of interest. A Complete Randomized Design (CRD) was employed in this study as an experimental design under a one-way Analysis of Variance (ANOVA). The finding of the study shows that Treatment 2 (consisting of 75% garden soil, and 25% wood ash) has a small effect (p-value=0.15) on the growth performance of scallions concerning the number of leaves. Moreover, results showed that organic fertilizer treatments significantly (p-value<0.01) affected the plant height of scallions at the last of the month. In particular, scallion plants treated with wood ash mixed with eggshells as fertilizer were higher in terms of plant height. Hence, the study recommends that egg shells and wood ash are suitable fertilizers to enhance the growth performance of scallions.
