Microbial community in garlic plants under different applications of organic fertilizer

Abstract

Indonesia is one of the biggest importers of garlic based on the FAO database in 2014-2018 and has continued up until now. Sustainable efforts to supply high domestic demand must be led to change this paradigm. Bacterial community study is important to identify soil health problems and provide insight and basic information to achieve sustainable agricultural management and increase production. This study aims to investigate the bacterial community around Garlic soil, which were treated with different manures (husk and goat’s dunk). Bacterial population enumeration was conducted by specific media and Amplicon sequencing analyses by Illumina was done to analyse bacterial community on some samples. Results showed that in general, highest population of bacteria which has plant growth promoting traits was shown in rhizosphere area with added organic material and bio fertilizer. Moreover, we observed that fertilization influences the bacterial diversity and composition in the rhizosphere, as bacterial taxa such as Rhodanobacter and Chuijabacter had higher abundance in the goat manure-treated plant in comparison to the plant grown in sandy soil.
