COTMAP was used to summarize plant map data taken at the end of the growing season from an experiment to determine yield and quality of cotton. The original experiment was designed to evaluate the interaction of nitrogen rate and Pix application systems. Plant map data was used to provide a detailed analysis of the plant structure variables and yield variables as they related to specific treatments. Any interaction which resulted could hopefully be related to the plant map data. There was no significant interactions determined between the main effect components so means were used across the N rate and Pix variables. There were direct relationships between total lint yield and the total number of bolls/plant as would be expected. The highest total lint yield and highest total bolls occurred where 90 lb N/A was applied. Other factors which showed significant response due to N rate included the number of sympodia with bolls in the first sympodial position, boll distribution, and boll retention. The Pix application systems had no effect on yield but did affect several plant structure variables including plant height, total nodes, and internode length.
