Project Title:
2023 Pea Seeding Rate
Objective:
To determine the most efficient seeding rate for field pea production in Northwest Montana
Personnel:
J.A. Torrion, Daniel Porter, P. Carr, Simon Fordyce
Summary:
Seven different seeding rates were deployed during this 2023 trial. Seeding rate ranged from three to fifteen live seeds/ft2. This trial determined that after nine live seeds/ft2, yield does not increase. Yield ranged from 11.53 Bu/A (3 live seeds/ft2) to 29.18 Bu/A (13 live seeds/ft2). For total agronomic performance, see table 2.
