Integration of Weed Management and Tillage Practices in Spring Dry Pea Production

Information about long-term efficient production systems is needed to assist growers in adopting conservation cropping practices for spring dry pea (Pisum sativum L.), a biologically important pulse crop grown in the Pacific Northwest and Canada. From 1985 to 1991, an integrated pest management field study examined the influence of three weed management levels and two tillage regimes on the productivity of spring pea grown in a winter wheat (Triticum aestivum L.)-spring barley (Hordeum vulgare L.)-spring pea rotation. When averaged over 6 yr, spring pea fielded the least with the minimum weed management level in either the conservation (chisel plow) or conventional (moldboard plow) tillage system
