AFX 457

AFX 457

AFX 457 Hi-Salt Alfalfa is designed for high yield, persistence, and superior forage quality in fields with high salinity (EC) or irrigated with high EC water. This variety is well-adapted to the Great Plains and Intermountain West, particularly where salinity restricts the production of dairy-quality hay. It features aggressive seedling growth for quick establishment, even in saline soils, without sacrificing yield in non-saline conditions. AFX 457 fits western production practices in areas growing fall dormancy 3, 4, or 5 alfalfa varieties, with medium-early maturity suited to late-bud harvest systems for maximum seasonal yield.

Alforex Seeds by DLF

Alforex Seeds by DLF™ offers a leading alfalfa lineup for North America, featuring elite genetics and technologies. Known for high yield and nutritional value, it supports greater productivity with advanced breeding and rigorous quality testing.
Hi-Salt®

Hi-Salt® alfalfa varieties were developed for high saline areas in North America, as higher salt concentrations in the soil can lead to seedling loss. Through focused breeding, these varieties are able to mitigate the effects by reducing salinity by 2.0 to 3.0 EC (electrical conductivity) points. This cutting-edge technology allows growers to plant alfalfa in areas previously considered unsuitable.
