I planted approximately 100 acres of certified fall mixes last year. The majority of the seed is wheat. I did plant 11 bags of combine wheat with 5 bags of winter peas on approximately 10 acres. It looks great. As far as the germination, I usually plant around 75 pounds of combine fall seed per acre to be on the safe side. I sprayed the field for weeds, so the weed seed should be minimal.
