2020 MSU Extension Soybean Variety Demonstration Program
During the 2020 growing season, a total of 26 on-farm soybean variety demonstration plots were successfully conducted. The following information is intended to complement data generated through small-plot Official Variety Trial testing programs.
Mississippi State University Extension wishes to express special thanks to the many producers who cooperated with this year’s on-farm soybean variety demonstration program, as well as to the Mississippi Soybean Promotion Board for their continued support of these efforts. In addition, we sincerely appreciate the seed companies and their representatives for their support of this program. The relationships among participating individuals are critical for the continued success of this program. Several staff members assisted in conducting this program: Lou Adams, Ben Stoker, Logan Duckworth, Michael Quin, and Ben Williams.
