Abstract


Bawang merah untuk benih umumnya diperbanyak dengan menggunakan umbi. Penelitian bertujuan untuk
memperbaiki cara perbanyakan umbi untuk benih yang berkualitas. Penelitian dilakukan di Desa Tambakan, Cagak,
Subang ± 600 m dpl. Rancangan percobaan menggunakan petak terpisah dengan tiga ulangan. Petak utama ada tiga,
yaitu ukuran umbi benih <3 g, 3-5 g, dan >5 g per umbi. Anak petak ada lima buah yaitu zat pengatur tumbuh enzim
karbonil 0,2 ml/l+ppc mikroelemen metalik 1,0 ml/l, enzim karbonil 0,2 ml/l + metalik 1,5 ml/l, triakontanol 0,2 ml/l +
metalik 1,0 ml/l, triakontanol 0,2 ml/l + metalik 1,5 ml/l, dan kontrol. Hasil penelitian mengungkapkan bahwa aplikasi
ukuran umbi benih >5 g per umbi yang diberi zat pengatur tumbuh triakontanol 0,2 ml/l + ppc mikroelemen metalik 1,5
ml/l nyata meningkatkan pertumbuhan dan hasil produksi bobot to tal umbi bawang merah untuk benih.

Ame lio ra tion of seed production technology of
shal lot by ap pli ca tion of proper size of mother bulb, plant growth regulators, and microelement nutrient.
Shal lot for seed generally are propagated by using the mother bulb. The aim of this experiment was to improve seed
production technology to find out high quality and quantity of shallot mother bulbs. Research was conducted at
Tambakan, Cagak, Subang ± 600 m asl. A split plot design with three replication was set up in the field. Main plot was
size of mother bulbs, viz. : <3 g, 3-5 g, and >5 g per bulb, respectively. Subplot was plant growth regulators treatment
in combination with microelement nutrient, viz. : plant growth regulaor en zyme carbonyl 0.2 ml/l + microelement
metalic 1.0 ml/l, en zyme car bonyl 0.2 ml/l + metalic 1.5 ml/l, triakontanol 0.2 ml/l + metalic 1.0 ml/l, triakontanol 0.2
ml/l + metalic 1.5 ml/l, and check. Research results revealed that application of size of mother bulb >5 g per bulb in
combination with pgr triacontanol 0.2 ml/l + metalic 1.5 ml/l significantly increased growth and total production of
shallot bulbs for seed.
