Upaya dalam meningkatkan pertumbuhan tanaman nilam dapat melalui penggunaan mikroorganisme tanah seperti rizobakteri dan mikoriza. Penelitian ini bertujuan untuk mengetahui pengaruh jenis rizobakteri dan jenis mikoriza terhadap hasil pertumbuhan tanaman nilam Aceh varietas Tapak Tuan. Penelitian ini telah dilaksanakan di Laboratorium Ilmu dan Teknologi Benih Fakultas Pertanian, Universitas Syiah Kuala, Darussalam Banda Aceh dari Desember 2023 sampai dengan Mei 2024. Percobaan ini dilaksanakan dengan menggunakan Rancangan Acak Kelompok faktorial dengan 3 ulangan. Terdapat dua faktor yang diteliti yaitu faktor pertama adalah rizobakteri indigenous dengan 6 taraf (Tanpa rizobakteri (kontrol); PS 4/4; PS 4/6; PS 4/7; PS 6/5; PS 8/12) dan faktor kedua adalah jenis mikoriza dengan 4 taraf (Tanpa mikoriza (kontrol); Glomus mosseae; Gigaspora sp.; Glomus mosseae + Gigaspora sp.). Parameter yang diamati meliputi tinggi tanaman, jumlah daun, luas per helai daun, jumlah cabang, panjang akar, volume akar, bobot biomassa basah tanaman, bobot biomassa kering tanaman dan persentase akar terkolonisasi mikoriza. Hasil penelitian menunjukkan bahwa jenis rizobakteri dan mikoriza yang diaplikasikan pada tanaman nilam mampu meningkatkan pertumbuhan tanaman nilam. Rizobakteri PS 4/6 merupakan isolat terbaik berdasarkan parameter tinggi tanaman, jumlah daun, jumlah cabang, volume akar dan persentase akar terkolonisasi mikoriza. Jenis mikoriza Glomus mosseae + Gigaspora sp. merupakan mikoriza terbaik berdasarkan parameter tinggi tanaman, jumlah daun, jumlah cabang, volume akar dan persentase akar terkolonisasi mikoriza. Interaksi terbaik terdapat pada perlakuan rizobakteri PS 4/6 dan mikoriza Glomus mosseae + Gigaspora sp. berdasarkan parameter luas per helai daun dan bobot biomassa basah.

Efforts to improve land quality due to excessive inorganic use of patchouli plant growth are through the use of soil microorganisms such as rhizobacteria and mycorrhiza. This study aims to determine the effect of the type of rhizobacteria and the type of mycorrhiza on the growth of Aceh patchouli Tapak Tuan variety. This research was conducted at the Laboratory of Seed Science and Technology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh from December 2023 to May 2024. This experiment was conducted using a factorial Randomized Group Design with 3 replications. There are two factors studied, the first factor is indigenous rhizobacteria with 6 levels (No rhizobacteria (control); PS 4/4; PS 4/6; PS 4/7; PS 6/5; PS 8/12) and the second factor was the type of mycorrhiza with 4 levels (No mycorrhiza (control); Glomus mosseae; Gigaspora sp.; Glomus mosseae + Gigaspora sp.). Parameters observed included plant height, number of leaves, leaf blade area, number of branches, root length, root volume, plant wet biomass weight, plant dry biomass weight and percentage of mycorrhiza colonized roots. The results showed that the types of rhizobacteria and mycorrhiza applied to patchouli plants were able to increase the growth of patchouli plants. PS 4/6 rhizobacteria is the best isolate based on the parameters of plant height, number of leaves, number of branches, root volume and percentage of mycorrhiza colonized roots. The type of mycorrhiza Glomus mosseae + Gigaspora sp. is the best mycorrhiza based on the parameters of plant height, number of leaves, number of branches, root volume and percentage of mycorrhiza colonized roots. The best interaction was found in the treatment of rhizobacteria PS 4/6 and mycorrhiza Glomus mosseae + Gigaspora sp. based on the parameters of leaf blade area and wet biomass weight.
