WD, that's for young new growth wheat. The only bennefit the wheat has at maturity is the seed heads , which deer will eat.
These are some options:
You can spray it know with gly(41%), work the ground in mid july and plant brassica.
You can let it go to it matures and develope seed, top dress brassica into it and than cut the wheat.(no till) Here you will have a volunteer crop of wheat and brassica stand.
If you want it do be a perenial plot. spray gly to kill the wheat, work the ground mid august and plant your clover with a cover crop of wheat or oats.
