ABSTRACT

COTMAN™ was developed to assist in management decision for average field conditions. In this study, COTMAN data collected from individual sampling locations within a field were compared to average field conditions in two distinct Texas growing regions. Both imagery and spatially dense maps of plant height were used to characterize the variability present in the field. It was found that different management recommendations could result within a particular field when regions of significant variability are considered separately. The results of this study suggest that COTMAN could be a useful tool in making site-specific management decisions, and that spatial data could in turn improve selection of COTMAN sample sites.
