My vote: They are the easiest plant to grow for plotting, but not all varieties are created equal. For example, the following do super well for me:
Groundhog radish, pretty much all turnips (Purple Top, Barkant and Appin), Bonar Rape, and T-Raptor. But, please note they only do really well for me when I terminate existing vegetation with Gly, then till and prepare a firm seed bed. Final steps are to broadcast and FERTILIZE WITH PLENTY OF NITROGEN. Skip any step or cut corners and all bets are off.
I am on the line between zones 5 and 6. I like to plant them between August 10 and August 15.
I have planted all of the following and they just are not as good of an option as those above. Some like the Kale take too long to mature. The DER does not put on as much tonnage as others but still takes up the same space. Sugar Beets are a pain unless roundup ready and then they are very expensive. And, Pasja just does not have the tonnage.
Barsica Rape, Dwarf Essex Rape, Bayou Kale, Kestrel Kale, Major Plus Sweede, Pasja, Winter Camelina, Winfred, Sugar Beets.
