umbuh relatif (kct-r), keserempakan tumbuh (kst), indeks vigor (iv) dan waktu yang dibutuhkan untuk mencapai 50% perkecambahan total relatif (t50). hasil penelitian menunjukkan bahwa perlakuan rizobakteri berpengaruh sangat nyata pada parameter potensi tumbuh maksimum dengan nilai 14,86%, daya berkecambah dengan nilai 15,44 %, kecepatan tumbuh relatif dengan nilai 9,77%, keserempakan tumbuh (kst) dengan nilai 11,47%, dan indeks vigor dengan nilai 7,37%. kata kunci : rizobakteri, viabilitas, vigor, pala abstract. this study aims to identify the effect of seed treatment using rhizobacteria that stimulate plant growth on viability and vigor of nutmeg seeds (myristica fragrans houtt). the research was conducted at the seed science and technology laboratory of the department of agrotechnology, faculty of agriculture, syiah kuala university, darussalam, banda aceh.. the research was conducted from december 2019 until june 2020. this research used a non factorial completely randomized design (crd). the factors studied in this study were 18 rhizobacterial isolates (ap 3/1, ap 3/10, ap 3/11, ap 4/1, ap 4/5, ap 5/3. ap 5/5, ap 5/6, ap 5/7, ap 5/8, ap 6/1, ap 7/1, ap 7/2, ap 7/3, ap 7/4, ap 7/5, ap 7/6, dan isolat ap 8/2) and 1 control which were repeated 3 times that there were 66 experimental units and continued with a duncan new multiple range test (dnmrt) at the 5% level. rhizobacterial isolates will be tested for their ability to viability and vigor of nutmeg seeds. each stage of the experiment was repeated 3 replications with each replication was planted 10 nutmeg seeds. the parameters observed in this study were maximum growth potential, germination capacity, simultaneous growth, vigor index, growth speed and the time needed to reach 50% of the seeds that were grown (t50). the results of the study showed that rhizobacteria had a significant influence on the parameters of viability and vigor of nutmeg seeds. rhizobacteria from ap 7/2 isolates showed the best maximum growth potential, germination power, vigor index, relative growth speed and growth simultaneity value compared with control treatments keywords : rizobacteria, viability, vigor,
