Brief Project Summary:

Iron-deficiency chlorosis (IDC) is a problem on high-pH soils where iron is not readily available to the soybean plant. There are genetic differences between varieties for tolerance. Growers need to know which private-company varieties are tolerant so that they can select the best variety for those fields that are susceptible to iron-deficiency chlorosis. Also, the NDSU soybean breeding project needs to identify experimental lines that have good tolerance to determine which experimental lines are worthy of release as named cultivars.

This project will provide visual IDC ratings with 1-best and 5-worst, averaged across multiple sites and replicated within each site. Approximately 350...

Information And Results
Final Project Results

This collection is the largest data set with the most comparisons of various company varieties (Roundup Ready, LibertyLink and non-GMO) for North Dakota and western Minnesota. Because the data are averaged across four locations with four replications per location, the data are quite reliable in helping growers select the best varieties for their IDC-prone fields. These data enable growers to increase their yield on IDC-prone fields because varieties with the least amount of yellow IDC symptoms will yield the best for fields that have that problem.

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.
