WyoWinter Winter Pea
A selection out of Austrian Winter pea for improved winter hardiness.
Variety Summary
WyoWinter Pea was developed by the University of Wyoming and the Wyoming Agricultural Experiment Station as an improvement on Austrian Winter pea.
WyoWinter has a yellow cotyledon and produces purple flowers. It is ideal for forage production, wildlife, feed grain, and for cover cropping. It has shown excellent winter hardiness in SE Wyoming and NW Nebraska and seems to be well adapted to the midstates.
Cover Crop Performance
In the October of 2019, researchers with the University of Tennessee planted extensive cover crop trials in three Tennessee locations – Knoxville, Spring Hill, and Milan. In addition to assessments of nitrogen content and release, assessment were conducted for ground cover, biomass and height. The data below reflects averages of all three sites. Site-specific data and complete results available upon request.

Coat for Optimal Performance
For optimal performance, WyoWinter should be inoculated with Rhizobium leguminosarum biovar viceae. This is best achieved with Nitro-Coat®.
