I was just watching the latest GrassDaddy video and he stated 2.5" is "maximum rhizome production height". I think I've heard that before numerous times. Is there a study to back that up that maybe shows rhizome production at different cutting heights? If rhizome production at 2.5" is for example only 10% greater than at 3", I might go with 3" instead as it looks a little darker and it may help root depth as well. If it's 30% greater, then I'd probably stick to 2.5". Anyway, it would be useful to have the data.

Yeah I couldn't find it, but I remember reading it on a university study. All I can find is references to the study by other documents. If anyone has it in their bookmarks please let me know what it is!

Still looking around for solid rhizome data, but did think this oldie was interesting regarding shoot density... http://archive.lib.msu.edu/tic/mitgc/article/197218.pdf

You mean you don't have a super-duper friend-of-a-friend custom built database of articles the likes of which Google has never seen? :lol:

That's great info. I wonder if shoot density would remain high if say you lowered the cut to 1", kept it there for a couple of months and then raised the HOC back up.

I know I've read a research paper around this. I'm on a work trip and can't reach my super duper custom SQL database, but I found this guidance from Purdue. They recommend 1.5in hoc during germination.

Nice article! What jumped out at me most in reading that article was the nitrogen application rates applied in the experiment: "Nitrogen fertility levels of (a) four, (b) six, (c) eight, (d) ten (e) twelve, and (f) fourteen pounds per 1000 sq. ft. per year."

Can't imagine any recent tests experimenting with nitrogen application levels of 8 pounds or more per year! Some of the other experiments described went all the way up to 16 pounds of N per year!
