Abstract. This study aims to examine the effect of the combination between rhizobium and
organic fertilizer on growth and development of soybean. This study was conducted in the
Research Station of Agriculture Faculty, University of Syiah Kuala, Banda Aceh from October
to November 2016. This experiment as arranged in a non-factorial randomized completely block
design three replications. The treatment were: control (without rhizobium and organic fertilizer),
without rhizobium + organic fertilizer, rhizobium + without organic fertilizer, rhizobium +
organic fertilizer, 0.5 dosage of rhizobium + 0.5 dosage of organic fertilizer. The variables
observed were plant height, number of leaves, number of nodules and number of effective
nodules. Treatment between rhizobium and organic fertilizer resulted in higher soybean high
and number of leaves. Treatments without organic fertilizer resulted in higher number of nodules
and effective nodules. That means that the number of nodules and effective nodules were better
when the medium was without organic fertilizer.
