The Potential of Organic Waste (Mushroom Baglog and Chicken Eggshells) as an Ameliorant on the Growth of Neolamarckia macrophylla in Subsoil Media

Abstract

Abstract This study aims to determine the growth response of Neolamarckia macrophylla to the application of mushroom baglog waste and chicken eggshell waste in subsoil media. The study was conducted in the greenhouse and soil content analysis was carried out in the Silviculture and Tree Physiology Laboratory, Faculty of Forestry, Hasanuddin University. The experiment was designed using a completely randomized design with a factorial pattern consisting of 2 treatments, mushroom baglog waste (X) consisting of 4 levels (X0 = without mushroom baglog waste; X1 = 10 g/polybag; X2 = 20 g/polybag; X3 = 30 g/polybag) and the addition of chicken eggshell waste (Y) consisting of 4 levels as well (Y0 = without chicken eggshell waste; Y1 = 5 g/polybag; Y2 = 10 g/polybag; Y3 = 15 g/polybag). Data were using Analysis of Variance (ANOVA). The results of this study indicate the addition of 5 g of chicken eggshell waste without mushroom baglog waste (X0Y1) in the subsoil has the best effect on the growth of N. macrophylla compared to other treatments. And if applied simultaneously, the growth of N. macrophylla is quite good at 10 g of mushroom baglog waste and 10 g of chicken eggshell waste (X1Y2).
