Jagung merupakan salah satu komoditas tanaman pangan yang mempunyai nilai dan peranan strategis setelah padi dalam pembangunan pertanian dan perekonomian Indonesia. Jagung mempunyai fungsi multiguna, baik sebagai bahan pangan, bahan baku industri maupun sumber pendapatan bagi petani. Hampir seluruh bagian tanaman jagung memiliki nilai ekonomis. Biji jagung sebagai hasil utama digunakan untuk bahan pangan, bahan pakan ternak, bahan baku penunjang industri dan bahan baku bioethanol. Penelitian ini bertujuan untuk mengetahui pengaruh varietas dan dosis mikoriza terhadap pertumbuhan dan hasil tanaman jagung hibrida. Serta untuk mengetahui interaksi antara varietas dan dosis mikoriza terhadap pertumbuhan dan hasil jagung hibrida. Penelitian telah dilaksanakan di Kebun Percobaan II Sektor Timur, Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh. Penelitian ini telah dilaksanakan pada September sampai Desember 2022. Rancangan penelitian yang digunakan yaitu Rancangan Acak Kelompok (RAK) pada faktorial 3×3 dengan dengan 3 ulangan, sehingga terdapat 9 kombinasi perlakuan dan 27 satuan percobaan, setiap satuan perlakuan terdiri dari 6 tanaman sehingga diperoleh total 162 tanaman. Penelitian terdiri atas dua faktor yaitu Varietas dan dosis mikoriza. Faktor pertama varietas terdiri dari 3 taraf yaitu :NASA-29, HJ, PIONER-32. Faktor kedua dosis mikoriza terdiri dari 3 taraf yaitu: 0 g tanaman-1, 5 g tanaman-1, 10 g tanaman-1. Parameter yang diamati yaitu tinggi tanaman, diameter batang, panjang daun, umur berbunga, berat tongkol berkelobot dan tanpa kelobot, panjang tongkol, diameter tongkol dan potensi hasil panen. Hasil penelitian menunjukkan bahwa varietas berpengaruh sangat nyata terhadap umur berbunga, berpengaruh nyata terhadap tinggi tanaman 15 HST dan tinggi tanaman 30 HST serta berpengaruh tidak nyata terhadap tinggi tanaman 45 HST, diameter batang 15, 30 dan 45 HST, jumlah daun 15, 30 dan 45 HST, panjang daun, berat tongkol berkelobot, berat tongkol tanpa kelobot, panjang tongkol dan diameter tongkol. Pertumbuhan dan hasil tanaman jagung hibrida lebih baik dijumpai pada varietas HJ. Perlakuan mikoriza berpengaruh berpengaruh sangat nyata terhadap tinggi tanaman 15 dan 30 HST, diameter batang 15 dan 30 HST, Jumlah daun 30 HST, berat tongkol berkelobot, berat tongkol tanpa kelobot, panjang tongkol dan potensi hasil panen. Berpengaruh nyata jumlah daun 15 HST serta berpengaruh tidak nyata terhadap tinggi tanaman 45 HST, jumlah daun 45 HST, panjang daun, umur berbunga dan diameter tongkol. Pertumbuhan dan hasil jagung hibrida yang terbaik dijumpai pada dosis mikoriza 10 g tanaman-1. Tidak terdapat interaksi antara varietas dan dosis mikoriza terhadap pertumbuhan dan hasil jagung hibrida terhadap peubah yang diamati.

Corn is a food crop commodity that has value and a strategic role after rice in Indonesia's agricultural and economic development. Corn has a multipurpose function, both as food, industrial raw materials and a source of income for farmers. Almost all parts of the corn plant have economic value. Corn kernels as the main product are used for food, animal feed ingredients, industrial supporting raw materials and bioethanol raw materials. This study aims to determine the effect of mycorrhizal varieties and doses on the growth and yield of hybrid maize. As well as to determine the interaction between varieties and doses of mycorrhiza on the growth and yield of hybrid corn. The research was carried out at the Eastern Sector II Experimental Garden, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh. This research was carried out from September to December 2022. The research design used was a Randomized Block Design (RBD) on a 3 × 3 factorial with 3 replications, so that there were 9 treatment combinations and 27 experimental units, each treatment unit consisted of 6 plants to obtain a total of 162 plants. The study consisted of two factors, namely variety and dose of mycorrhizae. The first factor of the variety consists of 3 levels namely: NASA-29, HJ, PIONER-32. The second factor mycorrhizal dose consisted of 3 levels, namely: 0 g plant-1, 5 g plant-1, 10 g plant-1. Parameters observed were plant height, stem diameter, leaf length, flowering age, weight of cobs with and without husks, cob length, cob diameter and yield potential. The results showed that variety had a very significant effect on flowering age, significantly affected plant height 15 DAP and plant height 30 DAP and had no significant effect on plant height 45 DAP, stem diameter 15, 30 and 45 DAP, number of leaves 15, 30 and 45 HST, leaf length, cob weight with husk, cob weight without cob, cob length and cob diameter. Growth and yield of hybrid maize plants were better found in the HJ variety. Mycorrhizal treatment had a very significant effect on plant height at 15 and 30 HST, stem diameter at 15 and 30 HST, number of leaves at 30 HST, cob weight with husks, cob weight without cobs, cob length and yield potential. Significantly affected the number of leaves 15 HST and had no significant effect on plant height 45 HST, number of leaves 45 HST, leaf length, flowering age and cob diameter. The best growth and yield of hybrid maize was found at a mycorrhizal dose of 10 g of plant-1. There was no interaction between varieties and mycorrhizal doses on the growth and yield of hybrid maize on the observed variables
