Austrian Winter Pea Cover Crop Plant

A quick-growing legume that can produce 90-150 lbs/ac of nitrogen, Austrian winter peas can be seeded with barley, oats, triticale and cereal rye for improved forage quality. In cover cropping, it can be used with Enricher radish in alternating rows, broadcast, or drilled in a mix containing annual ryegrass and rape after a soybean harvest. Austrian winter peas grow best in lower temperature, moist areas. It will likely winterkill when sustained temps are below 18°F if there is no snow cover.

Key Benefits

  • Ideal legume ahead of corn

  • Easy termination

  • Low C: N ratio

Herbicides To Avoid

Corn

  • Atrazine or simazine at >1 lb will be problematic for legumes and mustards unless lots of rain

    • <0.75 lab/A may allow for most legume cover crops, mustards, and annual ryegrass.
    • Atrazine < 1 lb/A can allow cereal grain establishment
  • Mesotrione (Callisto, Lumax, Lexar etc.), flumetsulam (Python) and clopyralid (Stinger, Hornet, SureStart) can be problematic for legumes and mustards like canola and forage radish.

Soybean

  • Chlorimuron (Classic, Canopy, Cloak, etc.), Imazethapyr (Pursuit), and fomesafen (Reflex etc.) could be a problem for fall seeded legume or mustard covers including radish. However, establishment of cereal grains should be OK.
