dc.description.abstractSoybean is a crop valued highly for its protein and oil content. Although soybean varieties have been regularly tested in Virginia for yield and other performance parameters, protein and oil measurements have not been collected prior to 2019. The purpose of this project was to compile data to determine if protein and oil content of Virginia soybean varied between year, location, cropping system, maturity group, or variety. Data was collected across five locations in Virginia over the 2019 and 2020 growing seasons for maturity groups 3, 4, and 5 in full-season and double-crop systems. While all factors examined affected protein and oil content, there was no consistency across time, location, cropping system, or maturity group. All factors interacted with each other; 2-, 3-, and 4-way interactions were present. There were differences in varieties for all experiments, except there were no protein differences for maturity group 3 varieties in either year; and, there were no oil differences in maturity group 3 varieties in 2019. Although cropping system differences occurred in 6 of 8 year-maturity group combinations and in 7 of 8 year-maturity group combinations for oil, in only one instance did cropping system interact with variety, indicating that differences of protein and oil content of varieties were relatively stable over cropping systems. Further data collection and analysis is necessary to determine consistencies within variables that affect protein content or oil content of Virginia soybean.en
