PERTUMBUHAN DAN PRODUKSI BAWANG MERAH (Allium ascalonicum L.) DI LAHAN GAMBUT YANG DIBERI AMELIORAN DAN PUPUK NITROGEN
Abstract: The objective of
research was to know the growth and production of onion after giving of ameliorant and nitrogene
fertilizer. The research was done in experimentation area Faculty of
Agroteknologi Universitas Riau, Rimbo Panjang village, subdistric Tambang,
Kampar from March to May 2015. The research was using the Randomized Block
Design Factorial with two factors. The first factor amelioran with five levels
namely control (A0), dolomite 1,5 ton/ha (A1), calcite 2 ton/ha, oil palm bunch
ash 5 ton/ha (A3) and rice husk ash 15
ton/ha (A4). The second factor of nitrogene fertilizer with three levels
namely control (N0), urea fertilizer 500 kg/ha (N1) and ZA fertilizer 1095
kg/ha (N2). Parameter observed were plant height, total of leaves, total tuber,
rim tuber, fresh weight tuber per plot and dry weight tuber per plot. The
result of the research showed that the ameliorant application was significant
of rim tuber, fresh weight tuber/plot, and reasonable save tuber weight/plot,
but not significant wet the plant height, total of leaves, total tuber.
Nitrogene fertilizer showed significant on fresh weight tuber per plot, and dry
weight per plot, but not significant the plant height, total of leaves, rim tuber,
total tuber. The interaction between ameliorant and nitrogene fertilizer showed
that no significant for all parameters. showed significant on fresh weight
tuber per plot and dry weight tuber per plot, but no significant the plant
height, total of leaves, rim tuber, total tuber.
