WinterKing Hairy Vetch
A PVP protected variety which began with selection work by Steve Groff in E. PA, WinterKing demonstrates improved winter hardiness, delayed flowering and the capacity to produce large amounts of high-nitrogen biomass.
Improved Winter Hardiness
Better winter hardiness equates to more biomass. More biomass provides increased forage for livestock, more biomass for cover croppers, and increased weed suppression for all. Those desiring high nitrogen-fixing legumes for green manure, forage grazing, wildlife and pollinator attractants should find WinterKing an improved option over other legumes that lack cold tolerance.
As an annual legume, hairy vetch may need to be terminated either mechanically or chemically when followed by a row crop. Some producers may find the late maturity of WinterKing reduces the potential for undesired seed propagation found in earlier maturing cover crop varieties. For livestock producers, WinterKing’s late maturity means more vegetative high value feed longer into the spring season.
WinterKing has shown potential to produce 150-200#N/acre, especially when allowed to reach maturity later in the season. This is beneficial for green manure as well as providing an extended high-protein source for grazing livestock throughout the full spring season.
Coat for Optimal Performance
For optimal performance, WinterKing should be inoculated with Rhizobium leguminosarum biovar viceae. This is best achieved with Nitro-Coat®.
