During 2003 and 2004, research was conducted with the aim of establishing to which extent the application of row spacing influenced soybean stem thickness under irrigation conditions. Results were processed using two-way analysis of variance for split-plot experiment (Hadzivukovic, 1991). Experimental factors were variety (big plot) and different row spacing (under plot). The average largest stem tickness (6.17 mm) was found in the variety Vojvodjanka. Differences among varieties in stem thickness was noted with a row spacing of 70 cm. In the best meteorological year for soybean production, significant differences were observed between the row spacing of 70 cm and the other two spacings (25 and 50 cm). A positive correlation between yield per plant and stem thickness of soybean was established. Based on the results, cultural practice recommendations were made for the soybean production.
