Giant grass offers clues to growing corn in cooler climes, researchers report

A giant perennial grass used as a biofuels source has a much longer growing season than corn, and researchers think they've found the secret of its success. Their findings offer a promising avenue for developing cold-tolerant corn, an advance that would significantly boost per-acre yields. The ...

Summer-dormant tall fescue grass shows promise for pasture improvements
