What are the odds my corn pollinates at temps of 97- 106? Corn is started tasseling a couple days ago, and the next 10 days or so are going to be hot. Ive heard that the high temps isn't that big of deal, but I find that hard to believe.

The early corn 'here' is startin to tassel too.
I was always told corn belongs to the "warm season grass" family. We'll see how warm it likes it. Warm nights work too don't they? 82* here at 4:30 this morning.
I'm guessing as long as moisture isn't an issue, it'll be alright. Shaded ground is still plenty damp 'here' as of today, but that might change pretty dam quick with the forecasted highs looking the way it does, if no moisture is added, ... still slight chances of rain for the next few days here.

We got some moisture last week which was good. Been very dry and hot, so the moisture doesnt last long. Cattle pastures are starting to get very as well, hope we catch a rain this week or it might get kinda bleak around here in places. Theres always hope I guess, could be worse, could be down in texas. I just hope that mess doesnt make it up here.

Ive heard that the high temps isn't that big of deal, but I find that hard to believe. What are your overnight temps? And what are you getting for dew at night? Corn can handle a lot of high temps, even at pollination, as long as it can respire at night. Dew at night helps more than most "experts" give it credit. It's a matter of keeping the silks viable. IF it is hot and dry with high night temps, they will not remain receptive as long as if you were experiencing lower temps and moisture. The biggest thing I would worry about is missing the "nick". The pollen production can sometimes precede silks of vice-versa. Do you have pollen production and viable silks? If so, no problem. |

Good post Dave....... I was out Sat and Sunday night late and yes we had some dew....... lesser amounts sunday night....... temps staying around 80 overnight....... checked today at 3pm on plants trying to pollinate.......... good pollen and silks are sticky...... hoping for the best. Also checked some corn that pollinated last week before we had rain and in upper 90's heat....... looked good. Will report back in a week or so... will try and get pics.

On my way to the office on Friday morning I went out into a field near our house, and was amazed. after three 98 degree days the corn showed excellent signs of pollinations and was working hard while I was out there. Paid for it all day.
FWIW. I did see a few spots that had some green snap, and just had to look at root system and they were flat as could be. Guess I was amazed that the roots had not really tried to reach into that subsoil moisture. must have snapped a month ago before the heat set in.
