ABSTRAK
Bawang merah merupakan sayuran penting di Indonesia yang dimanfaatkan umbi
lapisnya. Upaya untuk memenuhi kebutuhan bawang merah yang terus meningkat
dengan pemberian pupuk hayati dan pemilihan varietas yang sesuai dengan
wilayah lahan.Tujuan penelitian ini untuk mengetahui interaksi antara tiga varietas
bawang merah dengan konsentrasi Plant Growth Promoting Rhizobacteria untuk
mendapatkan pertumbuhan dan hasil tanaman terbaik. Penelitian dilaksanakan
pada bulan Maret sampai dengan bulan Mei 2020 di Lahan. Metode penelitian
menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri dari 2
faktor. Faktor pertama adalah varietas bawang merah terdiri atas 3 taraf yaitu
Varietas Tiron, Varietas Philip, dan Varietas Tajuk. Faktor kedua adalah
konsentrasi Plant Growth Promoting Rhizobacteria terdiri atas 4 taraf yaitu 0%,
1%, 2%, 3%. Analisis hasil menggunakan Annova pada taraf 5% dan diuji lanjut
DMRT pada taraf 5%. Hasil penelitian menunjukkan bahwa terdapat interaksi
antara varietas bawang merah dan konsentrasi bawang merah pada parameter
tinggi tanaman umur 14 hari, 28 hari dan jumlah daun per rumpun umur 14 hari.
Varietas Tajuk memberikan hasil yang baik pada parameter tinggi tanaman per
rumpun umur 42 hari, jumlah daun per rumpun umur 28 hari, jumlah daun per
rumpun umur 42 hari, jumlah umbi per rumpun, bobot segar umbi per rumpun,
bobot umbi kering per rumpun. Penggunaan konsentrasi PGPR 2% memberikan
hasil yang baik pada parameter diameter umbi.

ABSTRACT
Shallots is an important vegetable in Indonesia, mainly utilized for its bulb layers.
Decreased shallots production is often caused by root diseases due to unfavorable
environmental conditions. Efforts to meet the increasing demand for shallots are by
applying biological fertilizers and selecting varieties according to the area of land. The
aim of this research was to determine the interaction between the concentration of three
varieties of shallots and Plant Growth Promoting Rhizobacteria in order to obtain the
best plant growth and yield. The research was conducted from March to May 2020 at
Bantul, Yogyakarta. The research method used a Completely Randomized Block
Design consisting of two factors. The first factor was the varieties of shallots,
consisting of three levels: Tiron Variety, Philip Variety, and Tajuk Variety. The second
factor was the concentration of Plant Growth Promoting Rhizobacteria (PGPR),
consisting of four levels 0%, 1%, 2% , and 3%. Analysis of the results using Annova
at 5% level and further tested DMRT at 5% level. The results showed that there was an
interaction between the varieties of shallots and the concentration of PGPR on the plant
height parameter at 14 and 28 days old, as well as the number of leaves per clump at
14 days old. Tajuk Variety yielded favorable results in terms of plant height per clump
at 42 days old, the number of leaves per clump at 28 and 42 days old, the number of
bulbs per clump, the fresh weight of bulbs per clump, and the dry weight of bulbs per
clump. The use of 2% PGPR concentration produced favorable results in terms of bulb
diameter.
