Abstrak. cabai rawit (capsicum frutescens l.) merupakan salah satu komoditi hortikultura yang banyak dibutuhkan dan memiliki nilai ekonomi yang cukup tinggi di indonesia. salah satu cara yang dapat dilakukan untuk meningkatkan pertumbuhan cabai rawit adalah dengan menggunakan varietas unggul dan mikoriza. penelitian ini bertujuan untuk mengetahui pengaruh beberapa varietas dan dosis mikoriza gigaspora sp terhadap pertumbuhan tanaman cabai rawit serta mengetahui interaksi antara kedua faktor tersebut. penelitian ini telah dilaksanakan di kebun percobaan dan laboratorium hortikultura fakultas pertanian universitas syiah kuala, darussalam banda aceh yang berlangsung dari juni hingga agustus 2023. penelitian ini menggunakan rancangan acak kelompok pola faktorial 3x2 dengan 3 ulangan, sehingga terdapat 6 kombinasi perlakuan dan 18 satuan percobaan. faktor yang diteliti yaitu varietas yang terdiri dari 3 taraf yaitu varietas bonita ipb, feira ipb, dan shiara ipb serta dosis mikoriza gigaspora sp yang terdiri dari 2 taraf yaitu 0 dan 10 g tanaman-1. parameter yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, tinggi dikotumus, umur berbunga, dan persentase akar terkolonisasi mikoriza. hasil penelitian menunjukkan bahwa varietas berpengaruh sangat nyata terhadap parameter tinggi tanaman umur 30, 45 hspt, diameter batang umur 15, 30, 45 hspt, jumlah daun umur 15, 30, 45 hspt, tinggi dikotumus dan umur berbunga. pertumbuhan tanaman cabai rawit yang lebih baik dijumpai pada varietas shiara ipb. dosis mikoriza berpengaruh sangat nyata terhadap parameter tinggi tanaman umur 30 hspt, diameter batang umur 15, 30, 45 hspt, jumlah daun umur 45 hspt, tinggi dikotumus, umur berbunga dan persentase akar terkolonisasi mikoriza serta berpengaruh nyata terhadap parameter tinggi tanaman 45 hspt dan jumlah daun umur 30 hspt. pertumbuhan tanaman cabai rawit yang lebih baik dijumpai pada dosis mikoriza 10 g tanaman-1. terdapat interaksi yang sangat nyata antara varietas dan dosis mikoriza gigaspora sp terhadap diameter batang umur 30 hspt, kombinasi terbaik dijumpai pada perlakuan varietas bonita ipb dengan dosis mikoriza 10 g tanaman-1.

Abstract. Cayenne pepper (Capsicum frutescens L.) is one of the many horticultural commodities needed and has quite high economic value in Indonesia. One way that can be done To increase the growth of cayenne pepper is to use superior varieties and mycorrhiza. This research aims to determine the effect of several varieties and doses of mycorrhizal Gigaspora sp on the growth of cayenne pepper plants and determine the interaction between these two factors. This research was carried out at the Experimental Garden and Horticulture Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh, which took place from June to August 2023. This research used a Randomized Block Design with a 3x2 factorial pattern with 3 replications, so there were 6 treatment combinations and 18 experimental units. The factors studied were varieties which consisted of 3 levels, namely the Bonita IPB, Feira IPB, and Shiara IPB varieties as well as the dose of Gigaspora sp mycorrhiza which consisted of 2 levels, namely 0 and 10 g plant-1. The parameters observed were plant height, stem diameter, number of leaves, dicotum height, flowering age, and percentage of roots colonized by mycorrhiza. The results of the research showed that variety had a very significant effect 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, dicotum height and flowering age. Better growth of cayenne pepper plants was found in the Shiara IPB variety. The dose of mycorrhiza has a very significant effect on the parameters of plant height aged 30 HSPT, stem diameter aged 15, 30, 45 HSPT, number of leaves aged 45 HSPT, dicotum height, flowering age and percentage of roots colonized by mycorrhiza and has a significant effect on the parameters of plant height 45 HSPT and number leaves aged 30 HSPT. Better growth of cayenne pepper plants was found at a mycorrhizal dose of 10 g plant-1. There was a very real interaction between the variety and the mycorrhizal dose of Gigaspora sp on stem diameter at 30 HSPT, the best combination was found in the treatment of the Bonita IPB variety with a mycorrhizal dose of 10 g plant-1.
