Abstract: The yield and nutritional quality of spring wheat, oats and rye in the Jingtai Oasis was assessed in a trial planted in 2010. Measurements included calendar time and production data to harvest maturity, crude protein, crude fat, neutral detergent fiber, acid detergent fiber, ash and soluble carbohydrate content. The relationships among time to maturity and feeding value traits were also determined. The result showed that yield and nutritional quality of forage was able to be predicted by growth duration. Feed value and crude protein yield resulting from simulated grazing were assessed as significantly higher than making hay from the forage. The results provided a scientific basis for the production of cereal forages in an oasis environment.
