Abstract
Bacillus sp. is one type of bacteria that functions as PGPR (Plant Growth Promoting
Rhizobacteria). This study is designed to determine the effect of treatment duration time
immersion of mustard seeds with Bacillus sp and the doses of organic fertilizer on
growth and yield of mustard plants. The research was designed using Randomized
Block Design (RBD) Factorial with two treatments i.e. time soaking of mustard seed
with Bacillus sp. and organic fertilizer dose. The results showed that there was a very
significant interaction (P <0.01) between the treatment of soil seed immersion with
Bacillus sp. and the dosage of organic fertilizer on most parameters observed, except
for the root length of the plant. The highest fresh weight of the mustard plant was found
in the combination of the treatment of soaking of mustard seeds with Bacillus sp. for
20 minutes with a dosage of 1.50 kg organic fertilizer per plant that is 131,900 g, and
the lowest was found in the combination treatment of soaking of mustard seeds for 30
minutes with a dosage of 0 kg organic fertilizer i.e. 34.333 g, so an increase of
384.178%. The highest drying weight of the mustard oven was found in a combination
of treatment of soaking of mustard seeds with Bacillus sp. for 30 minutes with a dosage
of 1.50 kg organic fertilizer per plant of 8,000 g, and the lowest was found in a
combination treatment of immersion of mustard seed for 10 minutes with a dose of
organic 0 kg fertilizer per plant that is 4.617 g.
