Abstrak. Cabai Rawit (Capsicum frutescens L.) merupakan hasil pertanian yang mempunyai angka finansial tinggi. Upaya yang bisa dilakukan agar meningkatkan pengembangan tanaman cabai rawit yaitu dengan memanfaatkan benih unggul yang sudah terbukti dari varietas dan penggunaan kompos alami mikoriza. Tujuan penelitian ini untuk melihat efek beberapa varietas dan dosis mikoriza Glomus mosseae bagi pertumbuhan tanaman cabai rawit juga mengetahui hubungan kedua komponen tersebut. Pengujian ini telah berlangsung di Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh yang berlangsung sejak Juni hingga Agustus 2023. Rancangan yang dipakai yakni Acak Kelompok dua faktor 3x2 dengan 3 ulangan, 6 campuran perlakuan dan 18 unit percobaan. Variabel yang dikaji yaitu varietas terbagi atas 3 taraf yakni varietas Bonita IPB, Feira IPB dan Shiara IPB serta dosis mikoriza Glomus mosseae yang terbagi dari 2 taraf yakni 0 dan 10 g/tanaman. Indikator yang diperhatikan yakni tingkat tumbuhan, lebar batang, total daun, tinggi dikotomus dan usia berbunga. Hasil pengujian membuktikan bahwa varietas memberikan pengaruh amat nyata bagi parameter tingkat tumbuhan usia 15, 30, 45 HST, total daun usia 15, 30 HST, dan usia berbunga serta berinteraksi nyata bagi parameter tinggi dikotomus namun tidak menunjukkan pengaruh nyata bagi parameter lainnya. Pertumbuhan tanaman cabai rawit yang terbaik ditemukan pada varietas Shiara IPB. Dosis mikoriza memberikan pengaruh amat nyata bagi parameter tinggi tumbuhan usia 15, 30, 45 HST, lebar batang usia 15, 30, 45 HST, total daun usia 15, 30 HST namun tidak menunjukkan pengaruh nyata bagi parameter lainnya. Pertumbuhan tanaman cabai rawit yang lebih bagus ditemukan pada dosis mikoriza 10 g/tanaman. Terjadi kombinasi antara varietas dan dosis mikoriza. Kombinasi terbaik dijumpai pada perlakuan varietas Shiara IPB dengan dosis mikoriza 10 g/tanaman bagi parameter tinggi tanaman umur 45 HST.

Abstract. Cayenne pepper (Capsicum frutescens L.) is an agricultural product that has high financial figures. Efforts that can be made to increase the development of cayenne pepper plants are by using proven superior seeds from varieties and using natural mycorrhizal compost. The aim of this research is to see the effect of several varieties and doses of Glomus mosseae mycorrhiza on the growth of cayenne pepper plants and also to determine the relationship between these two components. This testing took place at the Experimental Garden of the Faculty of Agriculture, Syiah Kuala Darussalam University, Banda Aceh, which took place from June to August 2023. The design used was a 3x2 two-factor Randomized Block with 3 replications, 6 treatment mixtures and 18 experimental units. The variables studied were varieties divided into 3 levels, namely the Bonita IPB, Feira IPB and Shiara IPB varieties as well as the Glomus mosseae mycorrhizal dose which was divided into 2 levels, namely 0 and 10 g/plant. The indicators that are considered are plant level, stem width, total leaves, dichotomous height and flowering age. The test results proved that varieties had a very real influence on plant level parameters aged 15, 30, 45 HST, total leaves aged 15, 30 HST, and flowering age and had a significant interaction with dichotomous height parameters but did not show a real influence on other parameters. The best growth of cayenne pepper plants was found in the Shiara IPB variety. The mycorrhizal dose had a very real influence on the parameters of plant height aged 15, 30, 45 HST, stem width aged 15, 30, 45 HST, total leaves aged 15, 30 HST but did not show a real influence on other parameters. Better growth of cayenne pepper plants was found at a mycorrhizal dose of 10 g/plant. There is a combination of variety and dose of mycorrhiza. The best combination was found in the treatment of the Shiara IPB variety with a mycorrhizal dose of 10 g/plant for plant height parameters aged 45 HST.
