Penelitian ini bertujuan untuk mengetahui pengaruh isolat rizobakteri terhadap pertumbuhan dan hasil nilam aceh (Pogostemon cablin Benth.)., untuk mengetahui pengaruh mikoriza terhadap pertumbuhan dan hasil nilam aceh (Pogostemon cablin Benth.) serta mengetahui pengaruh interaksi isolat rizobakteri dengan mikoriza terhadap pertumbuhan dan hasil nilam aceh. Penelitian ini telah dilaksanakan di Laboratorium Ilmu dan Teknologi Benih, Laboratorium Ilmu Gulma Jurusan Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh dari Januari sampai Juli 2023. Percobaan ini dilaksanakan dengan menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 3 ulangan. Terdapat dua faktor yang diteliti yaitu jenis isolat rizobakteri (R) terhadap nilam Aceh varietas Tapak Tuan. Faktor kedua (M) adalah jenis tanaman tanpa mikoriza dan tanaman dengan Mikoriza Campuran (Glomus mosseae + Gigaspora sp.). Adapun parameter yang diamati antara Tinggi tanaman, Jumlah daun, Jumlah cabang,bobot biomassa basah, bobot biomassa kering. Hasil penelitian menunjukkan semua isolat rizobakteri yang diaplikasikan mampu meningkatkan pertumbuhan dan hasil tanaman nilam Aceh. Isolat rizobakteri PS 4/3 merupakan isolat rizobakteri terbaik berdasarkan parameter jumlah daun, jumlah cabang. Pemberian mikoriza campuran (Glomus mosseae + Gigaspora sp.) terbaik terhadap pertumbuhan dan hasil nilam Aceh berdasarkan parameter tinggi tanaman, jumlah daun, jumlah cabang, bobot biomassa basah, bobot biomassa kering. Interaksi sangat nyata pada pemberian mikoriza campuran dengan isolat PS 8/8PK berdasarkan parameter bobot biomassa basah dan bobot biomassa kering.

This study aims to determine the effect of rhizobacteria isolates on the growth and yield of Aceh patchouli (Pogostemon cablin Benth.), to determine the effect of mycorrhiza on the growth and yield of Aceh patchouli (Pogostemon cablin Benth.) and to determine the effect of the interaction of rhizobacteria isolates with mycorrhiza on growth and yield Acehnese patchouli. This research was carried out at the Seed Science and Technology Laboratory, Weed Science Laboratory, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh from January to July 2023. This experiment was carried out using a factorial Randomized Block Design (RAK) with 3 replications. There were two factors studied, namely the type of rhizobacteria isolate (R) against the Tapak Tuan variety of Aceh patchouli. The second factor (M) is the type of plant without mycorrhiza and plants with mixed mycorrhiza (Glomus mosseae + Gigaspora sp.). The parameters observed included plant height, number of leaves, number of branches, wet biomass weight, dry biomass weight. The results of the research showed that all rhizobacteria isolates applied were able to increase the growth and yield of Aceh patchouli plants. Rhizobacterial isolate PS 4/3 is the best rhizobacterial isolate based on the parameters of number of leaves and number of branches. Providing the best mycorrhizal mixture (Glomus mosseae + Gigaspora sp.) on the growth and yield of Aceh patchouli based on the parameters of plant height, number of leaves, number of branches, wet biomass weight, dry biomass weight. The interaction was very significant when administering the mycorrhizal mixture with PS 8/8PK isolate based on the parameters of wet biomass weight and dry biomass weight.
