Technical Abstract: Research findings were reviewed focusing on yield sensing, yield monitoring accuracy and yield reconstruction. With proper installations, calibration, and operation of yield monitors, sufficient accuracy can be achieved in yield measurements to make site-specific decisions. Nevertheless, attention must be paid when interpreting yield maps since yield measurement accuracy can vary depending upon the measurement principle, combine grain flow model, size of management area chosen, and the operator's capabilities and carefulness in following instructions to obtain the best accuracy possible under varying field operating conditions. Some of the errors can be filtered out by careful analysis of the raw yield (or flow rate) data provided by yield monitors. Better models of crop flow through combines are needed to reconstruct crop yield more accurately.
