The Next Instruments 3000H successfully gathered wheat grain protein data concurrent with yield monitor data acquisition. Within-field grain protein varies by 3% or more across the field. No grain protein trends were consistent across all 5 fields, but trends were found within individual fields. Protein data aggregation and/or smoothing is necessary for identifying within-field trends and for making comparisons with yield monitor data.
