_LR 5546 is an Agrisure Vipetra 3220 EZ Refuge hybrid that performs best in zone and north. The stalks and roots are rated good and the fall intactness is very good but the yield potential of this line should make you want to harvest early to avoid leaving anything in the field. It is ideally suited for higher populations and top-end management. Excellent tolerance to greensnap._
