Purple Top Turnip Cover Crop Plant

Established in mid to late summer, purple top turnips are used for grazing early fall into late winter. Turnips mixed with annual ryegrass and other cereal grains make a good fall feed when broadcast into corn or soybeans before harvest. The turnip tops and bulbs are both edible, highly digestible and a good source of sulfur. Purple top turnips should not be overseeded in excess of 2 lbs/ac in mixes.
