Yellowfeed is a harvesting method where an annual cereal crop grown for forage is sprayed with glyphosate at the milk-soft dough stage and allowed to stand until dry. Once dry the crop can be cut and then immediately baled. A study was conducted at 16 site by crop combination to monitor oat and barley forage yield and quality. After the application of glyphosate, dry matter yield was maximized at 20 days and protein concentration was minimized at 25 days. ADF, NDF, and TDN did not vary after glyphosate application. Yellowfeed is a viable alternative harvesting method when annual cereals are harvested for hay.
