Planting soybean cyst nematode resistant soybean varieties is one management option to increase soybean yields in North Dakota. Growers need unbiased information on the yield of commercial varieties in soybean cyst nematode (SCN) infested fields. This project involves soliciting soybean seed from private companies for planting in SCN-infested fields. The anticipated results will allow private companies and soybean growers to compare the yield of SCN resistant cultivars and breeding lines at three North Dakota sites that are infested with SCN. This study should help North Dakota soybean growers better cope with the growing SCN problem.
