Abstract

Bawang merah memiliki harga jual yang tinggi di pasaran. Penggunaan giberelin pada beberapa varietas bawang merah merupakan faktor pendukung dalam berhasilnya budidaya bawang merah. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari kedua faktor yang diteliti yaitu konsentrasi giberalin dan varietas, serta interaksi antara kedua faktor tersebut. Pelaksanaan penelitian dilakukan di Kebun Percobaan dua dan Laboratorium Hortikultura, Fakultas Pertanian, Universitas Syiah Kuala dari Juni hingga Agustus 2021. Rancangan penelitian menggunakan Rancangan Acak Kelompok faktorial 3 x 3 dengan tiga ulangan. Faktor yang diteliti yaitu konsentrasi giberelin (0 ppm, 125 ppm, dan 250 ppm) dan tiga varietas (Bima Brebes, Tajuk, dan Vietnam). Hasil penelitian memperlihatkan, konsentrasi giberelin berpengaruh nyata pada tinggi tanaman umur 40 HST. Tanaman tertinggi dijumpai pada perlakuan kontrol. Tinggi tanaman umur 70 HST tertinggi pada varietas Tajuk. Jumlah anakan per rumpun umur 30, 40, 50, 60 dan 70 HST, dan jumlah umbi per rumpun tertinggi pada varietas Bima Brebes. Tidak terdapat interaksi yang nyata antara kedua faktor yang diteliti. The Effect of Gibberellin Concentration on Growth and Yield of Several Shallot (Allium ascalonicum L.) VarietiesShallots are commodities that have a high selling value in the market. The use of gibberellins in several shallot varieties is a supporting factor to the success of shallot cultivation. The purpose of this research is to appropriate concentration of gibberellins and varieties, as well as the interaction between these two factors on the growth and yield of shallots. This research was conducted in Experimental Garden 2 and Horticulture Laboratory, Agriculture Faculty, Syiah Kuala University during June until August 2021. This research used a 3 x 3 factorial randomized block design that repeated three times. The factors researched was the concentration of gibberellins (0 ppm, 125 ppm, 250 ppm) and three shallot varieties (Bima Brebes variety, Tajuk variety, and Vietnam variety). The results showed, that the concentration of gibberellins significant to plant height on 40 DAP. The highest plants were found in the control treatment. The highest plant at 70 DAP was found in Tajuk variety. The best number of saplings per clump on 30, 40, 50, 60, and 70 DAP, and the number of bulbs per clump on Bima Brebes variety. There was no interaction between the concentration of gibberellins and shallot varieties on all observed variables.
