We planted sweet corn three weeks ago from seed. We are going organic, so we have only used natural pest control products. The plants are 5 to 6 inches tall. One week ago something took a bite out of one plant just above where the leaves begin to separate from the stalk. The plant fell over. Now four plants have been chomped on. There is no evidence of bugs or discoloration of the leaves or additional feeding spots. What is doing this, and what can I do to stop it?
You've probably got a rabbit. Hopefully this article can give you suggestions that will deter them.: https://www.gardeningknowhow.com/plant-problems/pests/animals/camouflage-gardening-deterring-garden-crashers-pests.htm
Why do the center stalks of corn grow better than the ones on the outer edge? My corn grows very slowly and does not produce around the edge of the crop when the center stalks grow great.
sorry, I didn't proofread well enough. "...removal of the suckers does not have much effect..."
Suckers are formed at the bottom of the stalk from the first through the 5th leaf.
Corn plants should be suckered to ensure a healthy single stalk, or at least that's what I was taught. Studies have shown that removal of the suckers or tillers (depending on your area) has much effect one way or another on the performance of a stalk of corn. I hope this answers your question.
How long does corn grow?
Corn takes approximately 40 - 80 days after sowing to flower, in other words, for the silk tassels to appear. Harvest occurs about 20 days after that. The amount of time is dependent on the variety of corn, the weather, water, soil, and nutrients. This article has more information on growing corn: https://www.gardeningknowhow.com/edible/vegetables/corn/grow-sweet-corn.htm
What about the suckers that grow at the bottom of some corn stalks? Should the suckers be removed so that the main stalk gets all the nutrients?
I have linked to an article below that will explain why these tillers or “suckers” are happening. The recommendation is to leave them be as there is no evidence to suggest that they impact corn yield and they “may” actually produce ears of corn themselves.

What is the best fertilizer for sweet corn? After planting we have had a tremendous amount of rain. The corn is 25 to 30 inches high and light green. Any hope?
Heavy rain can be difficult and hard on all of our garden crops.
Recommendations is a high Nitrogen fertilizer applied when the corn is about 6 inches high, then another application as the corn is forming it's silks.
My sweet corn is 4 to 8 in. tall. Each seed is stooled out. There is 2 to 4 stalks from each seed. Should I pick all but one or just let it grow?
Just leave it. Home garden corn actually does better if it grows in clumps as this improves pollination.
The corn stalks in my garden have only gotten 2 1/2-3 ft. The ears are growing but are maturing only approx 3 inches long and aren't filled in. Do I need to add a specific fertilizer? Did I plant too late? What causes this?
Premature tasseling of corn (producing ears before the corn is at its mature height) normally occurs because the plant is under stress of some kind. Without more information, I cannot tell you what is causing the stress. Take a look at the conditions that the corn is growing in and see if anything can be improved - such as more water, better drainage, more nutrients. You cannot save this season's crop but you can help avoid it for next time you plant if you can figure out what caused the stress.
