Corn seed germination???

7 posts in this topic

How long/how many years will a bag of seed corn still be good and have good germination?

I'm unsure on how big a plot I'm going to plant this year, it could be anywhere from 2-6 acres, if I stock up, how long will those extra bags keep, considering that seed is probably a few years old anyway, since the seed companies had to gather it and rebag it for conservation.

I would figure it going down some percentage every year and after its 3-4 years old I would get some newer stuff. If you have a chance you can usually pick up some torn bags or other donated seed at some seed plants. You could also contact your local Pheasants Forever chapter and get a new bag as they usually have some to give away.

You can do a gremination test. Count out 100 seeds. Put 2 to 4 layers of paper towels on a large plate, place seed flat on paper towels and cover all seed with 2 layers of paper towels. Keep paper towels and corn moist and warm for 6 to 8 days. I put mine on top of the fridge.

You also want to do a cold test. Do the same setup in your garage with temps around 50 degrees.

The amount of kernels that germinate out of the 100 will be your germination percent per bag.

Generally corn lasts a couple years, after that all bets are off and the percentage germ can drop rapidly. The germ test as suggested by huntmup is a good idea.

If you carry over any seed in the original bag take a small nail and poke a bunch of holes in the bag, sides, top and bottom. the reason for this is the seed bags are air tight and seed needs air cirulating to stay good. In the old days all seed was sold in a cloth bag that provided circulation. Just a old farmer. wink.gif

TEST IT before planting. Pioneer is having issues that new seed is only germinating at 70% so depends on how and where it's been stored. Legally after 2 or 3 yrs we can't sell most seeds. Test before planting

Thanks for the advice guys! I will test it before planting. I realize I could probably get more but I don't want to deprive someone else if the bags I have are still good. Plus corn is more spendy to establish, with the spraying and fertilizer costs, may as well do it right, even if its 'just a food plot'.

      I live north of the metro in East Bethel so not to familiar with south metro lakes. Minnetonka, Prior, Medicine, seem to have some popularity. On the north side the Chisago City area Green, Chisago, Lindstrom, Center, and Comfort are usually productive for pan fish, northern, walleye and summer bass. Big Marine also holds some nice crappie to 14" and larger Sunfish. Forest Lake and a bit west Coon lake also holds a variety. Last year I did a fairly extensive look at DNR lake surveys within a 3 hour drive north of the metro and came up with this list that looked promising for Walleye. I have fished a few during summer, but not all, with fair success.  Here is the list. This is typically what you will find on the DNR Lake Finder site only their survey will be for all species. I just took the walleye info. The Navionics link BringAnExtension listed should give you great contours for any of the lakes your interested in.

      Scored a lowrance Elite 5Hdi today for $169.99 (awesome sale). Plan to use this on ice and in boat for GPS purposes. Paired with the navionics app, excited to compare accuracy side x side.   If interested in the sale, it's at a store that rhymes with meander fountain..     This is an upgrade for me, I have used the app with good success. Hoping this new unit will be a bit more accurate.
