Rhizobium and organic fertilizer improve growth and development of soybean (Glycine max L.)

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.
