i planted 4 acres of dwarf sudan and got about 40 rolls off it over the summer. i just planted it right in the grass and it did well. put a little urea on it at the beginning of the year. it would of really helped to had a 2nd application.
i planted teff on a 1/2 acre in the middle of the sudan to see how it did. and it really didn't do anything..
i had about 40 lbs of it i threw in the planter and put in a light amount of sudan on about 50 acres last year... the sudan all came up but i didn't see 1 bit of teff.
i haven't had much luck with the teff at all.. i've tried with a no till, spinner spreader, newly disc ed ground etc.. and can't get it to come up.
