The IPM Weeds study near Pullman, WA uses two 3-yr crop rotations, two tillage systems, and three weed management (herbicide) levels. Spring pea average yields after 3 yr were higher with chisel plow than with moldboard plow, slightly responsive to increased weed management level, and highest with maximum weed management/chisel plow combination.
