ABSTRACT

PMAP is a Plant Map Analysis program for cotton developed at the Texas A&M Research and Extension Center at Corpus Christi, Texas. It was developed for research purposes but the flexible approach used to enter and display data makes it suitable for use by agriculture consultants and farm managers for the management of cotton crops. The program can be used on any IBM compatible computer equipped with 512 KB of RAM and a VGA color card and monitor. A math coprocessor is not required to rum PMAP, however it is highly recommended. Data viewing and editing is slow without a coprocessor.

As PMAP is executed the menu of options is displayed on the screen. PMAP has seven options: two options are for data entry and editing, two are for summarizing and displaying the data, one to set your hardware options, one to execute DOS commands and one to set parameters and units. Data entry and editing is accomplished by options are selected, a plant map with 90 fruiting positions is displayed on the screen. Using the arrow keys, the user can move the cursor to any fruiting site on the plant and enter the corresponding fruiting code to represent a square, green boll, set boll or vacant position.

PMAP was designed to analyze differences in fruiting characteristics of cotton plants as affected by experimental treatments or to examine differences in the fruiting status of commercial fields. This is accomplished by selecting the option to compare two existing map files from the main menu. As currently configured, this option allows the user to display the data graphically on the screen in twenty-six different formats. This option allows you to compare plant maps visualize and illustrate the effect of the treatment on the fruiting load of the plant. PMAP has been helpful in detecting and illustrating the effects of Pix and soil moisture supply on the boll load of cotton plants. The program has also been successfully used to study phenological differences among cotton cultivars. Information on how to obtained by contacting any of the authors of this paper.
