Sentinel plot at Allee Farm

Sentinel plot at Allee Farm
Two photos of the sentinel plot at Allee Farm near Newell, Iowa. Two maturity groups were planted at different times so we could have soybeans at a reproductive growth stage early but continue to have green soybeans late in the season. In addition, rows of maturity group 7 forage soybeans were planted within the plots. In September the regular sentinel plot is approaching maturity, but the forage soybeans are 40 inches tall and just beginning to bloom. (Ralph von Qualen)
