Penelitian ini bertujuan untuk mengetahui pengaruh beberapa varietas dan dosis mikoriza terhadap pertumbuhan dan hasil tanaman tomat. Penelitian ini dilaksanakan di Desa Lambhuk Kecamatan Ulee kareng Kota Banda Aceh. Pada Februari - April 2025. Rancangan yang digunakan Adalah Rancangan Acak Kelompok (RAK) pola Faktorial 3 x 3 dengan 3 ulangan, sehingga terdapat 9 kombinasi perlakuan dan 27 satuan percobaan, setiap percobaan terdiri atas 3 tanaman sehingga diperoleh total 81 tanaman. Penelitian terdiri dari dua faktor yaitu varietas dan dosis mikoriza. Faktor pertama Adalah varietas tomat terdiri dari: Tora IPB, Servo F1 dan Mutiara. Faktor kedua adalah dosis mikoriza Glomus mosseae terdiri dari: Kontrol, 10 g tanaman-1 dan 20 g tanaman-1. Parameter yang diamati tinggi tanaman, diameter batang, diameter buah, berat buah pertanaman, berat buah perbuah, jumlah buah pertanaman, kandungan vitamin C dan infeksi akar. Hasil analisis ragam menunjukkan bahwa varietas tomat berpengaruh sangat nyata terhadap diameter buah, berpengaruh nyata terhadap diameter batang umur 30 HSPT dan 45 HSPT, berpengaruh tidak nyata terhadap tinggi tanaman umur 15 HSPT, 30 HSPT dan 45 HSPT, diameter batang umur 15 HSPT, berat buah pertanaman, berat buah perbuah, jumlah buah pertanaman, kandungan vitamin C dan infeksi akar. Perlakuan mikoriza berpengaruh sangat nyata terhadap infeksi akar, dengan perlakuan 10 g tanaman-1 menghasilkan ifeksi tertinggi. Tidak terdapat interaksi antara varietas dan dosis mikoriza terhadap pertumbuhan dan hasil tanaman tomat.

This study aimed to determine the effect of various tomato varieties and mycorrhizal dosages on plant growth and yield. The research was conducted in Lambhuk Village, Ulee Kareng District, Banda Aceh City. From February to April 2025. A Randomized Block Design (RBD) with a 3 x 3 factorial pattern and three replications was employed, resulting in nine treatment combinations and 27 experimental units; with three plants per unit, the total sample size was 81 plants. The study involved two factors: tomato variety and mycorrhizal dosage. The first factor consisted of three tomato varieties: Tora IPB, Servo F1, and Mutiara. The second factor consisted of three dosages of Glomus mosseae mycorrhiza: Control, 10 g/plant, and 20 g/plant. Observed parameters included plant height, stem diameter, fruit diameter, fruit weight per plant, weight per fruit, number of fruits per plant, vitamin C content, and root infection. Analysis of variance (ANOVA) results indicated that tomato variety had a highly significant effect on fruit diameter and a significant effect on stem diameter at 30 and 45 days after transplanting (DAT). However, variety had no significant effect on plant height (at 15, 30, and 45 DAT), stem diameter at 15 DAT, fruit weight per plant, weight per fruit, number of fruits per plant, vitamin C content, or root infection. Mycorrhizal treatment had a highly significant effect on root infection but showed no significant effect on plant height (at 15, 30, and 45 DAT), stem diameter (at 15, 30, and 45 DAT), fruit diameter, fruit weight per plant, weight per fruit, number of fruits per plant, or vitamin C content. No interaction was observed between variety and mycorrhizal dosage regarding tomato plant growth and yield. Keywords: Tomato (Solanum lycopersicum), tomato variety, arbuscular mycorrhizal fungi (AMF),
