The objective of this study was to evalu- ate the effectiveness of post-save formulations of Wakatobi indigenous rhizobacteria in increasing the growth and yield of shallots. The study was conducted in Jati Bali Village, South Konawe District, using a Random- ized Block Design consisting of 10 rhizobacterial formulation treatments, a combination of three types of biological agents, namely Pseudomonas sp. LP03, Pseudomonas sp. TWB02 and Pseudomonas sp. TWB11, and three types of formulation materials: ground brick powder, ground burned rice husk powder, and bentonite; one control using NaCl 0.85%. The ex- periment was repeated three times so that there were 30 treatment units. The results showed that of the three types of rhizobacteria, only Pseudo- monas sp. TWB02 and Pseudomonas sp. LP03 displayed better perfor- mance to increase the growth and yield of shallots. These rhizobacteria were more compatible with the ground burned rice-husk powder formula- tion. The treatment of Pseudomonas sp. TWB02 and Pseudomonas sp. LP03 in the formulation of ground burned rice-husk powder increased shallot yield (tuber fresh weight) of 121% and 117%. Further research is needed on different environmental conditions to see the stability of these biological agents' effects on the growth and yield of shallots.
