Analysis of variance (<i>F</i> and <i>P</i> values) of the effects of year (Y), cultivar (Cv), row-type (RT, either single- or twin-row), and seeding rate (SR) on the concentrations of seed sugars (sucrose, raffinose, stachyose, glucose, and fructose, mg g^-1) and boron (B, mg kg^-1), phosphorus (P, g kg^-1), and iron (Fe, mg kg^-1) in soybean cultivars 94M80 and GP 533 in Sharkey clay soil. ^a

The experiment was conducted in 2009 and 2010 in Stoneville, MS, USA. a *Significant at P ≤ 0.05; **Significant at P ≤ 0.01; ***Significant at P ≤ 0.001. ‡NS, not significant.
