摘要: Highlight: Herbage yields, crude protein levels, and mineral concentrations of crested wheatgrass were influenced by phenological development distribution spring precipitation at the Archer Substation near Cheyenne, Wyo. Crude levels in declined with plant maturity. Amount enhanced or retarded development. Calcium uptake per acre was greater during a wet spring, but calcium concentration unit dry matter higher spring.
