To increase red onion production, it is necessary to formulate cheap and easy technology. This study aims to examine the effect of Bacillus subtilis on the growth and production of red onion ( Allium ascalonicum ). The research was conducted at the Laboratory of Plant Diseases, Department of Plant Pests and Diseases and Experimental Fam Land, Faculty of Agriculture, Hasanuddin University Makassar. The study was conducted from February to April 2020. 80-days old red onion were treated with Bacillus subtilis bacteria consisting of 4 levels, namely control (p0), 10 4 density (p1), 10 8 density (p2), and 10 12 density (p3). The results showed that the application of Bacillus subtilis affected the number of leaves, number of stems (tillers), number of bulbs, bulbs diameter (mm), and bulbs wet weight per plant (grams) with the best treatment at a density of 10 8 (p2). The rate of sprouting was not affected by the application of Bacillus subtilis. ## Keywords - Bacillus subtilis - Allium - Biology - Horticulture - Sprouting - Toxicology - Bacteria - Genetics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
