The average EONRs in each MZ in Field B defined using the three delineation approaches are shown in Table 4.Averaged across hybrids and fields，the EONRs were similar in 2001（174 kg$hm–2）and 2003（176 kg$hm–2），which were close to the farm practice（168 kg$hm–2）.However，EONR varied with different approaches，MZs，hybrids and years.Averaged across the field，the EONR of33G26 in 2001（139.7 kg$hm–2）was about 68 kg$hm–2less than that of 33J24，while in 2003，the EONRs of these two hybrids were similar.Averaged across years and hybrids，the general EONR trend for the ROSE and ROSE-YSTTS approaches followed the same order；MZ1>MZ4>MZ3>MZ2（Fig.4）.The difference in average EONR between the highest and lowest EONR MZs was larger for the ROSE-YSTTS approach（65 kg$hm–2）compared to the other two approaches（about 55 and 33 kg$hm–2）.
