Over half of my corn stalks have not produced ears. There are no apparent signs of disease, and I fertilized and watered as usual. Any ideas on how to avoid this crop failure next year?

If there is no sign of disease or insect damage, your problem could be caused by several other things.
The most common reason for no ears is the spacing between corn plants. Corn plants should be spaced 1 foot apart. If they are too close to each other, they may not produce ears.
Another reason could be improper fertilization. Too much nitrogen will produce a lot of leaves and no ears. Corn needs high calcium and potassium to produce ears when limited nitrogen is available. If you suspect this is the cause, have your soil tested to find out what you need to add. Contact your local Extension office for instructions.
The variety of corn you planted may affect ear production. Did you plant a new variety? How long to harvest?
