We investigated the suitability of the harvest method for mesh-based yield mapping and evaluated the efficiency of the yield map. The time required for the measurement using a 10×10-m mesh was about 6-8 minutes, which was about four times in comparison with the combine. Compared with the conventional method, as for the work time, it was about the same in field, but to be the whole that it includes for yield measurement in a half. The mesh-based method was as effective as the conventional method because the yield forecast in terms of the mean yield was the same with both the methods, but the fluctuation indicated by their methods was considerably different. The yield map and a quality map, which was derived using a tested grain sampler, were used to investigate the influence of fertility and soil moisture content.
