I drilled at 25#/acre fall of 2017, JD 1960's drill set on 7" coulter spacing. This spring I cut it and had a stellar crop....with all the things you need for growth applied, but in reasonable quantities on the fert. but had lots of rain.
Tell you how good it was, I couldn't rake it into WWs initially; too thick. I scattered it with the tedder and came behind the tedder and baled scattered clippings and made the best bales I ever baled with my current Jd 375 roller. Once I made a few passes through the field to thin things out I got out the rake and raked up WWs and finished baling.
The other neat thing was that it was still raining in May when I baled but by some nook or crook, I got about a week of clear weather with good sun shine and low humidity with good North winds. I was fretting (and posted herein) on worrying about losing the crop. Didn't happen. You just never know!
