This is why ND farmer wants higher protein.

I would recommend 10 GPA liquid urea sprayed with flat fan nozzles soon after flowering is complete.  I have seen 0.5% to 1.0% increase in protein with liquid urea and very little to no leaf burn, but to be safe, I would not spray urea on a hot day.  UAN+water will cause some burn depending on humidity, amount of dew, temp and time of day.  UAN+water sprayed on a hot day would look like you used paraquat.  Also, liquid urea may boost protein better than UAN. 

Fun Fact:  Stream bars are great during the tillering stage, but useless for post anthesis N application.
