Sounds to me like your corn isn't getting enough water. You might have to water every day in poor soil. Corn, more than any other vegetable, needs lots of water and nitrogen to make a good crop. If your plants leaves are curling midday, you aren't watering enough.

I grew Miari 301 for the first time this yr. It has very well filled out ears and is very sweet. The kernels are much deeper than Kandy Korn that I was growing. But any shortage of water or nitrogen shows up as smaller plants and smaller ears.

thank you Fruitnut for the info :) I will water it really well now, The corn I did get off of it, even the smaller ones were very tender and sweet, awesome corn!

Corn does fine, ... in Ohio. It is a heavy feeder and needs moist soil. A good 3 feet deep silt loam with good irrigation and lots of fertilizer.
For what you get, there are so many better veggies to grow in a small garden, but if you must grow it, be sure to allow enough room between stalks.........at least 6 inches, and rows three foot apart. Weed rigorously until the corn is about 2 feet tall.
And for all that work , two ears of corn.
If I grew corn, I'd get Painted Mountain or an OP variety so I could save seeds.
