%T PENGARUH PEMBERIAN EKSTRAK UMBI BAWANG MERAH (Allium
cepa L.) TERHADAP PERTUMBUHAN TANAMAN BABY KAILAN

(Brassica oleracea L.)
%X Onion (Allium cepa L.) is one of the plants to contains auxin and gibberellin
which can help plant growth. The purpose of this research is to know the effect of
giving onion bulb extract on the growth of baby kailan (Brassica oleracea L.).
This experiments used Completely Randomized Design (CRD) with single factor
namely onion bulb extract (Allium cepa L.) with 5 levels concentration as
treatment: 0% v / v (control), 10% v / v, 20% v / v, 30% v / v, and 40% v / v. Each
treatment was repeated 5 times. Variables in this research were the number of
leaves, plant height, leaf area, leaf dry weight and leaf stalks, and chlorophyll a, b,
and total. The data obtained were homogenized by Levene test, then analyze the
variance with 5% significant level. If there is a difference between treatments,
then it is continued with Turkey (HSD) test is done at the 5% significant level.
The results of this experimets showed that onion bulb extracts was quadratic
correlated with the number of leaves, plant height and leaf area, and there was
increase significantly at 10% v/v extract concetration. Dry weight was quadratic

correlated onion bulb extract and was increase significantly at 10% v/v and
20%v/v extract concetration. Onion extract bulb does not have significant effect
on the content of chlorophyll a, chlorophyll b or total chlorophyll. The results of
this research can be concluded that the onion bulb at 10% v/v extract concetration
has an influence on the number of leaves, plant height, leaf area, and dry weight
and has no effect on chlorophyll content.
