You are correct that the plant determines ear size about the 5 leaf stage. Any type of stress (NPK, moisture, compaction, ect.) will effect size. Later in the season pollination problems or stress at that time will cause kernals to abort and ear length to decrease but have no effect on the number around.
Corn ear size ?
