FSG 423ST alfalfa was selected for persistence and high forage yield from parent plants growing in the saline soils of the northern Great Plains. Due to it’s tolerance to saline soils, branching/tap root system and great disease resistance package, FSG 423ST produces high quality, fine stemmed hay and tolerates variable soil types. FSG 423ST is adapted to the Great Plains, North Central Region and the winterhardy Intermountain Region of the United States. Not just for saline soil conditions, FSG 423ST alfalfa is an excellent choice for any area where a high yielding, superior forage quality alfalfa variety is desired.
