In an established perennial clover stand - how much volunteer rye you all get after mowing after the seed has dried down? That would be waiting until about Sept 1 for me.
I'd like to leave my rye standing for fawns + turkey, quail nesting this year.
My clover plots get very thick with clovers so I don't get a lot of germination if I let the rye mature and mow it...which is why I drill rye into the clovers.
But...in cover crop stands where the clovers are not quite as thick you would get a lot of free rye by mowing the previous rye crop after the seed becomes viable.
This is a cover crop I had drilled the previous August (2020). This is June 11, 2021. While most of the crop had winter killed or been fully consumed by deer, I still have plenty of Hairy Vetch, Crimson and Medium Red Clovers, and Rye the following year. There was a lot of great forage here so I let it stand. It did provide nice fawning and turkey cover as well.
June 16th
July 15th. I knew I wanted to mow the rye to provide a new crop of rye in this plot but the seed wasn't viable yet on this date.
A week or two later the seed is becoming darker and hard ...
I mowed it with my brush hog on August 7th...
After some timely rains....9 days later on August 16th I've got a lot of volunteer rye coming up...
August 30th - 21 days after mowing the rye I've got a great looking food plot with lots of rye, clovers, and vetch to feed my deer again.
Don't have any more photos but the deer fed in this plot all fall and will be in there again when the snow melts in the spring. Keep in mind, I am getting 2 years of forage out of this plot and all I did was mow it once a year after first drilling it. I didn't fertilize it or over seed it with anything except for the volunteer rye which came up on its own after I mowed it. If I remember I can post some updated photos of it this coming spring when the rye grows above the clovers. I will terminate this cover crop in early July this year and drill my brassicas into it.
So yes - if the clovers are not super thick you can get a good crop of volunteer rye by just mowing it when the seed becomes viable.
