Iron Deficiency Chlorosis (IDC) is an annual challenge for soybean producers in certain areas of our state. This issue is most common on soybean grown in our high pH soils. While there are some alternative management practices that may help producers to overcome this issue, variety selection is likely the most simple and economical option currently available. With that said, data generated through trials designed to screen soybean varieties for tolerance to IDC may offer producers who deal with this issue an additional point to consider when making variety selection decisions. Through a collaborative effort between MSU Extension and MAFES Variety Testing, a total of 119 maturity group IV and V soybean varieties were screened for tolerance to IDC during the 2021 growing season. MSU Extension and MAFES sincerely appreciate the Mississippi Soybean Promotion Board and each of the participating seed companies for supporting these efforts. The following links are to each document summarizing the different soybean variety sets for the maturity ranges and technologies evaluated during 2021:
2021 Maturity Group 4.5-4.6 RR2X/XF Soybean Variety Response to IDC
2021 Maturity Group 4.7-4.9 RR2X/XF Soybean Variety Response to IDC
2021 Maturity Group 5.0-5.7 RR2X/XF Soybean Variety Response to IDC
2021 Maturity Group 4.5-4.9 Enlist E3 Soybean Variety Response to IDC
