Eastern North Carolina has a rich tradition in soybean production. Soybeans in the MG V-VII have performed well here. Many of our acres were also double-cropped behind wheat, pushing our planting dates into July on occasion. However, in recent years, we have seen an expansion in acres devoted to production using MG III-IV varieties. While these varieties are vulnerable to quality damage when harvest is delayed due to weather, they have yielded very well, causing more growers to look at earlier planting dates using earlier varieties. The reduction in wheat acres, leading to fewer double-cropped soybean acres, has also contributed to the interest in planting earlier and earlier maturing soybeans.

Brief Project Summary:

Choosing early maturing soybeans from maturity groups 3 and 4 has become more common in North Carolina. This project aims to quantify the yield response of soybeans in MG 3 and 4 to varying plant populations, planting dates and row spacings. This research also plans to identify a nutrient uptake curve for MG 3 and 4 soybeans. Then, efforts intend to quantify yield response to additional nitrogen, sulfur and potassium applications.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
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.
