_This is Lathams earliest version of our leafy, silage-specific hybrids. Excellent late-season plant health and growth make this robust hybrid a top choice for producers, who need an earlier maturing hybrid for northern production or late-planted forage needs. The hybrid gets to harvest moisture in timely fashion and its late-season plant health extends your silage harvest window. Its not intended for use as a grain hybrid._
