The plot was planted on May 18, two weeks later than I would have liked. The corn emerged very quickly and was fast-growing. A pre-emergent herbicide application with the high rate of Heat and glyphosate to provide some residual control is a must with corn as it is not a competitive crop with weeds. As soon as more weeds were visible, the first in-crop application was applied using Armezon and glyphosate at the 6 leaf stage. A starter fertilizer of 150 lbs/ac of MESZ in a 2×2 band was applied to provide 18-60-15-1.5. Nitrogen was top dressed at two different times, with the first application of 80 lbs on May 21, with the second application of 80 lbs on June 9 at about the 5 leaf stage. Both nitrogen applications were made with UAN (28-0-0) dribble banded. There was a small amount of leaf burn but the corn grew through it and looked really good all year round.
