PENGARUH PUPUK ORGANIK DALAM MENGEFISENKAN PUPUK NITROGEN UNTUK PERTUMBUHAN DAN PRODUKSI TANAMAN BAWANG MERAH (Allium ascalonicum L.)
Abstract: The objective of
research was to know the effect of organic fertilizers in efficiency addition
of nitrogene, organic fertilizers and nitrogene fertilizers, and for to obtain
growth and yield of onion (Allium ascalonicum L.) was good with high
efficiency. The research has been conducted in the area of Agricultural
Extension Hall, the village of Sungai Geringging, subdistric Kampar Kiri,
Regency of Kampar, Riau Province. This research conducted in 4x2 factorial experiment,
arranged in a Randomized Block Design (RAK). The first factor is organic
fertilizer itc, without organic fertilizer, animal manure 25 ton/ha, the rice
straw compost fertilizer 31,25 ton/ha, green manure 10 ton/ha. The second
factor the source of nitrogene itc urea 543 kg/ha, ZA 1190 kg/ha. The observed
parameters include the total of leaves, plant dry weight, N uptake efficiency,
total tuber, convolution tuber, fresh weight tuber, weight shelf of tuber, the
effect of organic fertilizer on the efficiency of nitrogene production. The
results of research, showed treatment green fertilizer and urea fertilizer
produced the highest yield on the observation weight shelf of tuber is 2,60 kg/
plot.
