There are many, many factors that could cause either of these statements to be true: year-to-year weather variation, yield potential differences in and between fields, planting date differences, etc. (first published March 2019, last reviewed March 2024)

These demonstration and research results are a collaborative effort of Virginia Cooperative Extension (VCE) Agents and Specialists, Virginia producers, and agribusiness. The purpose of this publication is to provide research-based information to aid in the decision-making process for soybean producers in Virginia. It provides an unbiased evaluation of varieties, management practices, and new technologies through on-farm replicated research using producer equipment and time. These experiments enable producers to make better management decisions based on research and provide greater opportunities to improve yields and profits, which improves quality of life for them and their families.

These demonstrations and replicated studies provide information that can be used by Virginia corn growers to make better management decisions on their farm. These results should be used along with data from other replicated studies when making decisions. Refer to individual location results for additional detail.

The research and demonstration plots discussed in this publication are a cooperative effort by Virginia Cooperative Extension employees, Virginia Tech and Virginia State University, numerous producers, and many members of the Virginia agribusiness community. The fieldwork and printing of this publication are mainly supported by the Virginia Corn Check-Off Fund through the Virginia Corn Board. This is the forty-first year of this multi-county cooperative project. Further work is planned for 2025. Anyone who would like a physical copy of this publication should contact their local extension office, who can request a copy from the VCE Northumberland County Extension Office.

Virginia Cooperative Extension takes pride in the premise that vital programming is based on the issues, problems, and needs of the people. A thorough analysis of the situation provides context for understanding and addressing these problems. Each local office updates their situation analysis every 4-5 years.
