Effect of Induced Compost by Cellulolitic (Aspergillus fumigatus) and Ligninolitic (Geotrichum sp.) Fungi Inoculum Application on Vegetative Growth of Red Chili (Capsicum annuum L.)

Abstract

Green waste (GW) is an important fraction of municipal solid waste (MSW). The composting of lignocellulosic GW is challenging due to its low decomposition rate. Therefore the use of fungi inoculum as a decomposer inducer on GW composting needs to study. The purpose of this study was to explore the potential of the compost induced by cellulolytic (Aspergillus fumigatus) and ligninolytic fungi (Geotrichum sp.) inoculum application on vegetative growth of red chilly plants (Capsicum annuum L.). This research was conducted in the green house of the Faculty of Agriculture the University of Lampung, Indonesia. Completely Randomized Design was adopted with five treatment dose of cellulolytic and ligninolytic compost amandmend of 0%, 10%, and 20% each (K= control, S1= Cellulose 10%, S2= cellulose 20%, L1= Ligninolytic 10% and L2= ligninolytic 20%). Parameters observed were plant height, dry weight, relative water content and chlorophyll of a, b and total. The results demonstrated that compost induced by cellulolytic fungi (Aspergilus fumigatus) and ligninolytic (Geotrichum sp) produced the optimal effect on growth parameters across all treatments. The compost application could increase significantly plant height, dry weight, relative water content. But not the chlorophyll content of a, b and total. The maximum measurements of plant height, dry weight, relative water content was achieved by S2, L2, L2, K and L2 treatments respectively. These results suggest that the inoculum induced compost has bene cial impacts for the use as organic fertilizer to enhance vegetative growth.
