Brief Project Summary:

Herbicide-resistant waterhemp is problematic for many North Dakota soybean farmers as it can germinate throughout the growing season. Obtaining a crop canopy is an important part of waterhemp management. Iron deficiency chlorosis (IDC) can delay canopy closure and prolong the waterhemp germination window in fields with IDC issues. Oats can be inter-seeded into soybeans to help alleviate IDC symptoms and fall-seeded cereal rye can suppress early-season flushes of waterhemp. This project will look at the early-season companion crop suppression capabilities of spring-seeded oats, and the role oats play in late-season waterhemp management.

Key Benefactors:
farmers, agronomists, cover crop applicators, extension specialists

Information And Results
Project Deliverables

Extension bulletin addressing the use of barley or oats in a systems-approach to alleviate IDC in soybean with the overall goal of waterhemp management.
-Results will be shared at Extension meetings and Scientific meetings.
-Trials will be on display at Weed Science Field Days that are open to the public.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
