Little River, TX | This hay curing talk is more attuned to conditions in the northern corn belt than for Texas, but there are lessons to be learned for Texas.
I watched the Pan Evaporation for TX & WI this season for comparison.
I can see why direct sunshine is given a lower priority up there.
HERE we can cure down to where all or most of the respiration is finished by sunset on the day of cutting.
A real difference!
Obviously some of my great truths are conditional truths, NOT universal truths.

Edit addition.
On page 5 is two charts that I have enlarged and translated for my own use. The Pan Evaporation I added a trend line for 66% of the ground covered, and streatched yield out to 3 tons/A. I translated metric to American common usage scale.
Then I built a quick estimate chart for yield and pan evaporation for the various swath widths that I use. Kind of rough but it works for me.
For an 0.40" pan evaporation and >2 T/A the results are very encouraging.
