• Yield of Crested Wheatgrass Following Release from Sagebrush Competition by 2,4-D

      Robertson, J. H. (Society for Range Management, 1969-07-01)
      Rate of increase in yield of crested wheatgrass following use of herbicide on associated sagebrush was measured over four years, including the year of treatment. Significant increases in yield, which were probably worthwhile economically, did not begin until the third year after spraying.
