The Impact of Experimental Design on the Application of Grazing Research Results: An Exposition

Funding limitations often restrict pasture replication in grazing research on rangeland. Consequently, subsample error has been used to estimate treatment effects or characterize populations. Assumptions associated with experimental designs which utilize subsample error to make inferences are discussed and an example evaluated. The appropriate experimental unit for inferential grazing research is the pasture. Animals or vegetation sampling within pastures must be considered as subsamples in inferential grazing research. Pasture replication must be used in intensive grazing trials to establish treatment differences or provide adequate characterization. Following intensive trials, extensive, unreplicated trials implemented by private producers can be effective in establishing broad-based applicability. Unreplicated pasture trials may also be used for screening several treatments.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
