Brief Project Summary:

Soybean growers in the Red River Valley of North Dakota commonly select cultivars based on iron deficiency chlorosis (IDC) scores. They assume that these cultivars will yield well on heavy clay soils that are subject to excessive soil moisture and poor drainage. However, the heavy clay soil commonly does not have a high pH and IDC is not a problem. The goal of this project is to determine whether cultivars that are tolerant to IDC are also high yielding on poorly drained and excessively wet soils where IDC is not a problem.

The project involves testing thirty cultivars with varying IDC scores in either rain-fed or water saturated field plots. Irrigation will be used to assure the...

Final Project Results

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.
