AFX 779 Hi-Ton Alfalfa is a high-yield, semi-dormant variety designed specifically for the growing conditions of California, Arizona, New Mexico, and western Texas. This variety demonstrates stable yield performance even in later production years, making it a reliable choice for long-term cultivation. Adapted for aggressive management systems that utilize five to six cuttings per season, AFX 779 features salinity tolerance.
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.
Hi-Ton® alfalfa varieties offer high yield, disease resistance, and pest resistance for growers who want to push their alfalfa acres to maximize seasonal dry matter. These varieties ensure faster growth and recovery after harvest by accelerating green-up by 3 to 5 days, leading to more cuts per season and increased yield potential.
