Abstract

Three row spacings and three soybean cultivars were examined under irrigation conditions during a two-year study. The objective was to determine the influence of row spacing changes on fertile node number of soybean. The analysis of variance was performed on data following a two-factorial split-plot design , with cultivar and row spacing as main plot and subplot factors, respectively (Hadzivukovic 1991). The number of nodes with pods present was significantly dependent on maturity group. The late cultivar was determined to have a significantly greater number of nodes with pods (1.95 to 2.78), as compared to the early and medium maturity cultivars. An increase in row spacing resulted in an increasing number of fertility nodes (12.05, 12.37, and 13.51).  A positive correlation was established between yield per plant and fertile node number.
