Abstract

The main aim of this study was to evaluate the effect of rhizobial inoculation, treatment of soybean seed with fungicides and application of Bioalgeen-S90 as a growth biostimulator on nodulation and symbiotic nitrogen fixation efficiency. The pot experiment was conducted in 2004 in a randomized complete block design in four replicates with a three factorial arrangement of treatments. The positive effect of rhizobial inoculation on nodule number, nodule dry weight, total nitrogen content in soybean aerial parts and stem, ureide concentration in xylem was determined. Foliar application of Bioalgeen-S90 significantly increased nitrogen content in soybean aerial parts and stem but on nodule number, nodule dry weight and ureide concentration in xylem the influence was not determined. Significantly lower nodule dry weight, total nitrogen content in soybean aerial parts and stem, ureide concentration in xylem were determined in pots with fungicide and amino acid treatments.
