Large-seeded, cool season annual. Best companion-seeded with a spring cereal grain to encourage climbing and minimize lodging.
Pea-small grain mixtures can also be harvested as forage, yielding 1-3 TDM per-acre, with slightly higher forage quality and palatability than small grain forage alone.
Nitrogen credits to a following crop are minimal. Credit 20 lbs N per-acre if the peas reached near-maturity.
Seeding rate: Peas are recommended for planting in mixes:
- 30-40 lbs Trapper field peas* with 20-30 lbs oats or barley for cover only;
- 50 lbs Trapper field peas* with 30-45 lbs oats or barley for forage production.
*Seed size varies considerably among varieties (Trapper is larger than many – fewer seeds per pound).
Seeding depth: Seed the peas, or the mix, ½ inch deep.
Fertility needs: Peas will fix most, but not all, of the N required for optimum growth. Apply 15 to 30 lbs supplemental N to optimize biomass production (2 to 3.5 TDM per-acre).
Inoculate with Rhizobium leguminosarum biovar viciae (R. viciae).
