• Significance of Reduced Plant Vigor in Relation to Range Condition

      Bjugstad, A. J.; Whitman, W. C. (Society for Range Management, 1970-05-01)
      In Southwestern North Dakota, forage yields were much higher on ranges in excellent than on those in good condition; differences in forage yields between ranges in good and those in fair condition were smaller. Reduced yields were due mainly to reduced vigor of midgrasses, as reflected by plant height, and not to loss of plants.
