Analysis of variance (F and P values) of sucrose, raffinose, stachyose, glucose, fructose (mg g^–1), boron (B, mg kg^–1), phosphorus (P, g kg^–1), and iron (Fe, mg kg^–1) in soybean as influenced by year (Y), seeding rate (SR), planting date (PD), and row-type (RT, single- or twin-row) in Sharkey clay soil in 2009 and 2010 at Stoneville, MS, USA.
