Northern Michigan scrub oak and jackpine blow sand here.
We buy $14 per 100# bags of field rye, very cheap. 19-19-19 fert.
put 1/4 down with 1/4 fert, a month later another 1/4 of seed with little more fert....Doing this over the course of summer. Sometimes mixed with a few #s of cheap mixed birdseed.
Makes a fair plot in the shade and sand of northern Michigan.

Thanks everyone. I will give some of this a try. I'll keep you posted.

A lot of the kale crops have shade tolerance, along with beets, carrots and radishes etc. I would think some of the food plot crops related to those would work in a mix as well.
