Climate change has occurred frequently, and it lead to a severe decrease in marketability and productivity. Onion has various functional elements related to antioxidant, antibacterial, anticancer and immune enhancement, the productivity is closely affected by climate conditions. In this study, to environmentally-friendly produce onions even though drought condition, effect of Bacillus aryabhattai H19-1 on the yield, marketability, and functional component of onions was evaluated in a field. When strain H19-1 was drenched, onion production and marketability significantly increased, and the contents of ascorbic acid and carotenoid of harvested onion bulbs also increased. Therefore, B. aryabhattai H19-1 is expected to be effective in enhancing onion productivity by mitigating drought stress.
