I planted some I had given to me for food plots for 5 years. The 4th year, I thought my 1890's JD planter messed up and skipped a few. Last year I finished out that seed in my "new" planter, no tilling into standing beans. Only about half of it grew. I got something different this year

Most of it will grow, if it was stored properly. We did a test plot with some of our new brand of corn (Becks) and some of the older Mycogen that was left from a couple years before. It yielded competitively, so it really didn’t bother it much to be older. We usually buy several pounds extra of sweet corn seed and put it in the freezer for years to come.

This was stored in the shed on a concrete floor and no moisture got to it, but it was subject to temp. change ie. hot and cold.

Do a germ check. Get the wife's cake pan, put a inch of dirt or potting soil in it and plant 100 seeds. Keep in an area that will stay above 70* then count how many come up. Better yet plant some in her house plants, she'll keep em watered for you.

It doesn’t matter that you kept in the dry. Some times it will germ and sometimes not. I just threw away 3 bags that was that old only a few grains per sample would germ. Do as Lee says

Seed company I worked for back in the 90's would do germination tests on small grains. Lay out a couple paper towels. Place a row of seeds across center of towels, fold towels in half over seeds. Get towels wet and let sit a few days. You can open towels up to check on progress of germination.

I also do the paper towel test and use the wife's cookie sheet. She used to scream more when I used dirt.

Only way to know is to do the germination test. 15 bags....so we're talking a "farming operation" not just food plots or whatever. You could up the rate some if the germ test shows lower germination.

From what I've heard on the price of seed now, by the seed not pound anymore, I would definitely test it and/or plant it.

Most of you would be shocked at the TRUE age of the seed you plant!ALL COMPANIES do germ tests, submit the results to the various states,,,,,,,,,, and that resulting date becomes the date on the end of the bag. But heck,,,,,,,, if it germs out at 96-7%,, what does it matter? Less than 90% usually become salvage corn and is burnt in power plants,,,,,,,,,,, or roasted, and the coating burnt off to feed to hogs. (This depends on the seed coat of course!) Of course placing seed in a "salvage" class is resisted a lot! Soybeans are a different breed of pups because they don't retain the germination factor like corn!

And yes, John,,,,,,,,, corn seed has been sold by the 80,000 kernel unit for several years now,,,,,,,,,,,, not by the pound weight. If you check your bags,,,,, I'd bet it describes the unit as 80,ooo seeds, with a bag weight of ####.# pounds.(I've seen this vary between 37 and 48 pounds a lot.........................

I farmed two very pieces of land and always used some old seed to fill out the planter instead of buying another bag. Could never tell the difference always yielded good

mix it in with your new seed, it'll cross pollinate with the other plants. I've put last of a bag seed in with new seed before, never hurt my yield any!

There was a couple people who actually did count a bag of corn! According to our seed person, it took them all night, and it was right about 80,000.

How old? The year prior.....? Me too. 2 years? How old was it to begin with (as dipstick points out)? Point is, a germination test is super easy to do, extremely inexpensive in the scheme of growing corn, and the only way you will really know. A screw up in poor germination could easily cost $1000's on the scale this guy is asking about.
