AFX 469 Hi-Ton Alfalfa is designed for growers who aggressively manage their established alfalfa fields. Its FastGrowth ability allows it to reduce the time between harvests by 3 to 5 days, maximizing seasonal yield. With very early harvest maturity, AFX 469 reaches late bud or early flower stages 3 to 5 days ahead of most dormant alfalfas. It exhibits average seedling yield performance when spring direct-seeded, and its rapid green-up after harvest accelerates growth to harvest maturity.
