Sometimes you have to dig a little for answers when your corn crop emerges unevenly, which can hurt ear counts, says Missy Bauer, Farm Journal Associate Field Agronomist. Bauer provides these simple directions to determine the causes of uneven emergence.
1. Dig up a corn plant, look at the root system and find the old seed. Note that the mesocotyl extends up to the base of the crown.
2. Hold the base of the crown at the 3⁄4″ line of the measuring tape, as demonstrated in the photo above. Then, measure the length of the mesocotyl down to the bottom of the seed. This measurement is your planting depth for that specific plant.
