PENGARUH VERMIKOMPOS TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN BAWANG MERAH Allium ascalonicum L.

The research had been done to know the influence of vermicompos to the growth and production of shallot crop Allium ascalonicum, L. to know the influence of vermicompos to the growth and production also compared them of shallot crops to media that vermicompos mixed and didn’t since July to October 2008 that took place at wire house of Basic Science, Biology Department, Mathematics and Natural Sciences Faculty, Bengkulu University. The
research used Completely Random Design method with 6 threatments and 4 times repeating,
which were : V0 = without vermicompos, V1 = 300 g vermicompos, V2= 600 g vermicompos,
V3 = 900 g vermicompos, V4 = 1200 g vermicompos, V5 = 1500 g vermicompos with total
planting media volume much 4000 g. The data that reached was analyzed by using analysis
of varian and continued by using Duncan’s New Multiple Range Test (DNMRT) on 5%
level because F counted > F table. Based on the research result reached that vermicompos
gave influence that concreatly different with treatments by using vermicompos. Media
without vermicompos showed the lowest result for each of the parameters which were; the
leaf length 32.6 cm; number of bulbil dry weight of bulbil each of theme were 5 cloves and
11,8 g; total dry weight 18.2 g. For media that used vermicompos, the highest result for each
of parameters reached by adding 1500 g vermicompos for each polibags. The leaf length was
47.8 cm; number of bulbil were 10 cloves; dry weight of bulbil was 36.1 g and total dry
weight 44.9 g. The highest shallot crop production reached on addtioning vermicompos 1500
g vermicompos for each polibag which was 9.02 tons/ha and the lowest production for
without vermicompos treatment which were 2.95 tons/ha.
