I guess it just depends on what you want the stand ti look like. I know, another question. To get right down to it, we gotta' figure out how many plants of each type per acre. How many seeds in a pound? Germination rate? I know, now it's getting too complicated. Consider this:
Austrian Winter Peas 1,800 seeds per pound Straight Seeding rate / acre 75 - 150 lbs
Seed Oats: 15,000 per pound Straight Seeding rate / acre 32 - 64 lbs
Rye (grain) 19,000 per pound Straight Seeding rate / acre 56 - 112 lbs
Turnip Seed 10,000 per OUNCE! Straight Seeding rate / acre 1.5 - 2.5 lb
Daikon Radish 30,000 per pound Straight Seeding rate / acre 10 lb
I'm not sure I'm a big fan of the mix,but since I'm not paying for it here's what I'd do:
Peas: 50 lbs per acres or none at all. i'm going to assume the peas germinate and three weeks later they are gone resulting in many happy deer and not so much competition for the other plants in the mix.
Seed Oats: 32 lbs per acre. It's a full rate, but, if you get it to germinate and have any deer population at all, the oats will get mowed down as the peas are eaten. Then, the oats freeze over winter.
Rye: 25 - 50 lbs per acres. I'd want the rye as a filler for everything else. It's tough. It'll germinate early. Given the oats and peas and radishes, I don't want too much rye in competition. But, you could think just the opposite. Pour on the rye and lighten the other seeds.
Turnip: It's just me, but i plant turnips lightly. A little seed goes a long way and the tops consume a lot of space and make too much surrounding shade. I'd go with 2 or 3 ounces.
Radish: I like radishes! I'm planting 5 pounds!
OK. Given all of that, how many plants per acre?
Peas; 50 lb x 1,800 seeds per acre = 90,000
Oats 32 lb x 15,000 = 480,000
Rye 25 lb x 19,000 = 475,000
Turnips 3 oz x 10,000 = 30,000
Radish 5 lb x 30,000 = 150,000
I've gone on too long. There are enough plants there to fill about an acre-and-a-quarter assuming a 100% germination rate. I'm happy with it.
If you skip the peas, add an ounce of turnips, and 25 lbs of rye.
