Topographic Position Index Predicts Within-Field Yield Variation in a Dryland Cereal Production System

Agricultural systems exhibit a large degree of within-field yield variability. We require a better understanding of the drivers of this variability in order to optimally manage croplands. We investigated drivers of sub-field spatial variability in yield for three crops (hard red winter wheat, Tritic...
