Abstrak. Tujuan penelitian ini untuk melihat efek beberapa varietas dan dosis mikoriza Gigaspora sp bagi pertumbuhan tanaman cabai rawit juga mengetahui hubungan kedua komponen tersebut. Penelitian telah dilakukan di Lahan Percobaan dan Laboratorium Hortikultura Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh, yang berlangsung mulai Juni hingga Agustus 2023. Rancangan yang dipakai yaitu Acak Kelompok dua faktor 3x2 dengan 3 kali 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 Gigaspora sp yang terbagi dari 2 taraf yakni 0 dan 10 g tanaman-1. Hasil penelitian ini memperlihatkan varietas memberikan pengaruh sangat nyata bagi parameter tinggi tanaman pada 30, 45 HSPT, diameter batang pada 15, 30, 45 HSPT, jumlah daun pada 15, 30, 45 HSPT, tinggi dikotumus dan umur berbunga. Pertumbuhan cabai rawit lebih bagus ditemui di varietas Shiara IPB. Dosis mikoriza memperlihatkan pengaruh sangat nyata pada indikator tinggi tanaman 30 HSPT, diameter batang 15, 30, 45 HSPT, jumlah daun 45 HSPT, tinggi dikotumus, umur berbunga serta tingkat infeksi kolonisasi akar, namun menunjukkan pengaruh nyata di tinggi tanaman pada 45 HSPT dan jumlah daun umur 30 HSPT. Pertumbuhan tanaman cabai rawit yang lebih bagus terdapat di dosis mikoriza sebesar 10 g tanaman-1. Ditemukan hubungan sangat nyata dari varietas dan dosis mikoriza Gigaspora sp pada diameter batang umur 30 HSPT, kombinasi terbaik dijumpai pada perlakuan varietas Bonita IPB dengan dosis mikoriza 10 g tanaman-1.Pengaruh Beberapa Varietas dan Dosis Mikoriza Gigaspora sp terhadap Pertumbuhan Tanaman Cabai Rawit (Capsicum frutescens L.)Abstract. The aim of this research is to see the effect of several varieties and doses of Gigaspora sp mycorrhiza on the growth of cayenne pepper plants and also to determine the relationship between these two components. The research was carried out at the Experimental Field and Horticulture Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam 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 Gigaspora sp mycorrhizal dose which was divided into 2 levels, namely 0 and 10 g plant-1. The results of this research show that varieties have a very real influence on the parameters of plant height at 30, 45 HSPT, stem diameter at 15, 30, 45 HSPT, number of leaves at 15, 30, 45 HSPT, dichotum height and flowering age. Cayenne pepper growth is better found in the Shiara IPB variety. Mycorrhizal dosage showed a very real influence on the indicators of plant height at 30 HSPT, stem diameter at 15, 30, 45 HSPT, number of leaves at 45 HSPT, dicotum height, flowering age and the level of root colonization infection, but showed a real influence on plant height at 45 HSPT and number leaves aged 30 HSPT. The better growth of cayenne pepper plants was found at a mycorrhizal dose of 10 g plant-1. A very real relationship was found between the variety and mycorrhizal dose of Gigaspora sp on stem diameter at 30 HSPT, the best combination was found in the treatment of the Shiara IPB variety with a mycorrhizal dose of 10 g plant-1.
