Figure 1. Effect of planting beans 2 (Early) or 4 (Late) wk after planting corn on mixture dry matter yield over four environments. Means are separated with orthogonal contrasts within each bean planting date and mixture. Pairs of bars with * are different at P < 0.05.

Figure 3. Effect of planting corn at a density of 82,500 plants ha–1 (normal) or a density of 55,000 plants ha–1 (low) on bean concentration in mixtures over four environments. Means are separated with orthogonal contrasts within each corn density and mixture. Pairs of bars with * are different at P < 0.05.
