Abstract
One of the challenges in providing high-quality maize seeds is the presence of seed-borne pathogenic fungi, which can affect the seed quality and lead to diseases in maize plants. Endophytic bacteria Bacillus sp. have been extensively studied for their ability to produce secondary metabolites with antifungal properties. The aim of this research is to determine the effect of secondary metabolites produced by endophytic bacteria Bacillus sp. in suppressing the infection levels of seed-borne pathogenic fungi on maize seed, as well as its potential in enhancing germination and growth of maize plants using the blotter test and growing on test methods. This study employed a Completely Randomized Design with four concentration levels (10%, 15%, 20%, 25%) and two strains of endophytic bacteria Bacillus sp. (Bth-31a and Bth-22). The results of pathogenic fungi identification carried by maize seeds revealed the presence of Fusarium sp., Aspergillus flavus, Aspergillus niger, and Rhizopus sp. All seed treatments using secondary metabolites from Bacillus sp. managed to suppress the infection levels of seed-borne pathogenic fungi on maize seed compared to the control in both the blotter test and growing on test methods. Furthermore, the treatment with secondary metabolites from Bacillus sp. contributed to increased germination capacity and growth of maize plants in both the blotter test and growing on test methods. Keywords: Bacillus sp., Maize, Secondary Metabolites Compound, Seed-borne Pathogen Fungi
