CONCLUSIONS
In this study, SCMZ and YBMZ techniques were
evaluated for grain yield production and the accuracy
with which they characterize grain yield within low,
medium, and high productivity potential management
zones. Results from this study indicate that the SCMZ
technique is relatively more accurate than the YBMZ
technique for characterizing in-field areas of different
productivity potential. Both techniques have deficiencies
and could be improved. This study does, however,
indicate that the inclusion of more data layers to a management
zone delineation technique does not necessarily
improve the overall accuracy of the technique, as
evidenced by the data-intensive YBMZ technique being
less accurate than the SCMZ technique.
