Publication Number: P3799
View as PDF: P3799.pdf

During the 2021 growing season, a total of 31 on-farm soybean variety demonstration plots were successfully conducted. The following information is intended to complement data generated through small-plot variety 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 its continued support of these efforts. In addition, the seed companies and their representatives are sincerely appreciated for their support of this program. The relationships among participating individuals are critical for the continued success of this program.

Assistance in the conduct of this program provided by Ben Stoker, Ben Williams, Owen Tyrone, and Paul O’Neal.
