Persoanlly, I think it all depends on when the pollen sheds, and when you get rain. If you get rain, and soon, so the plant is somewhat healthy looking when the tassels come out, and the silks emerge in time to catch the pollen, I wouldn't be surprised if you still got 120 BU corn, provided it kept raining.
On the other hand, it doesn't look a whole lot better than my 13BPA corn did, at that time. The tassels came out, pollen fell, the pollen dried up, and only then, did I see silks emerge. Even though it rained some after that, all I gut were 'nubbins'.
From my personal guess, I'd say somewhere between 20 & 120 BPA, depending on the weather from here on out, but with the potential dropping every day. I hate to give such a wide window, but really, if it starts raining tomorrow, there is quite a bit of yield that can be salvaged.
One thing, personally I don't have a lot of acres of row crops (roughly 200) with some furrow irrigated, and some under a pivot, and a little dryland.
With the furrow irrigation, I never worry about wind, or low humidity disrupting the watering of the crop.
However, with the pivot, I can 'cool' the field during pollenation (I use well water, which comes out of the ground around 55 degrees) with a quick 1/4 or 1/3 inch of water, during pollenation, which also adds humidity to the air in the field, and does wonders for pollenation.
On years where pollenation is not a problem, the furrow irrigation almost always is the better corn.
My dryland yields in the last 10 years have been from 13 to 160 BPA. I guess that puts my dryland acres in what they call the 'fringe'.
I got myself a 'birthday' present, a digital camera coming from Amazon next week. If I can figure it out, I hope to post a few pictures of what things are like here. The biggest surprise are the heay fields. We got about a 80-90% of normal first cutting, and second cutting on all dryland fields but one, will be non-existant. The bulk of the field doesn't even have a green hue to it, 3 weeks after 1st cutting was put up.
