Data shown in the table represents spring seeded small grain species grown in Minnesota.
Quality, crude protein and in vitro digestible dry matter is highest at boot stage when the forage yield was 38 to 42 percent of that at dough stage. These small grains were fertilized with 75 pounds per acre of added nitrogen and not planted as companion crops. Removing small grains at boot stage allows for double cropping with another annual such as sudangrass, rape or ryegrass.
