To start w/, why do you give a rat's @$$ about what others think?  Maybe your question was just misworded.

I will tell you i've seen ZERO yield increases from nitrogen apps in the spring....this is upto 180#.  I have never tried putting it down at or during any of the reproductive stages....there may be some merrit to that IDK.  There were a few instances i saw yield losses and just from my observations (always unscientific), there was little to no nodulation so i concluded they didn't have the nitrogen bank to draw from when it came to grain fill. 

Bottom line was it hurt when i did that, so i stopped doing it.
