Gylling Data Management, Inc.
Providing Research Software Solution Since 1982!


Since the first release in 1982, the ARM program has become a useful tool for crop production and crop protection research trials, plus a broad range of agricultural disciplines. Our software is a valuable tool that saves our customers time throughout the research season. The software saves time creating trials, collecting and analyzing data, and producing the many reports required for successful and timely trial management.
The ARM software written by Gylling Data Management, Inc. (GDM) is a recognized and respected standard throughout the crop protection industry for managing plant science research data. Our software is used worldwide by researchers and managers in 80 countries, many companies, and hundreds of universities.

ARM Overview

ARM is software to plan, create, manage, analyze, and report planned efficacy experiments. While ARM is typically used for crop production and crop protection experiments by field or greenhouse researchers, it also works well with many non-cropland plant experiments. ARM is designed to manage and summarize on a single-trial basis. See this ARM introduction tutorial (pdf) for an overview.
ARM is designed to run on Microsoft Windows 7 or newer operating systems. ARM offers many built-in reports that can be customized with many options. Reports can be printed to Microsoft Word or Excel with a single button click, giving full flexibility for reporting.
The ARM author was a crop protection researcher for more than twenty years, and understands your research needs. We encourage users to call with their computer questions and ideas. Many ARM features are suggestions from our current ARM clients. GDM provides free support for the current version of all software that GDM markets.
Researchers with little or no previous computer experience can easily understand ARM. Context sensitive help screens and tutorials are included. ARM gives the best return for the price with the most flexible reporting capabilities of any research data management software.
See our ARM Brochure (pdf) for more information about ARM, and see our Products Update newsletter (pdf) for the latest information about all GDM products.

Trial Reporting

ARM gives great flexibility in printing reports. Design your reports by listing the ARM report components in any order, then create a report set. Report sets can be saved with your custom options for each component, and used again later. You have nearly unlimited choices on information and arrangement in reports.
Following are the ARM report components that are available to use in creating your report sets:
ARM Reports
Protocol Audit Trial
Other customized reports
Protocol Data Headers
Site Description
Protocol Description
Spray/Seeding Plan
Protocol Plot Data Footnotes
Standardized Summary
Protocol Product Amount Totals
Labels (many sizes)
Status Report
Tour Report
Protocol Schedule
Plot Data Footnotes
Summary Plot Data Summary
Treatment List Comments
Protocol Spray/Seeding Plan
Plot Map
Summary AOV Means Table
Trial Audit Trial
Protocol Treatments
Plot Signs
Summary Factorial AOV Table
Trial Comments
Data Collection
Trial Map
Summary Correlations
Trial Treatments
Data Verification
Product Amount Totals
Summary Dose-Response Analysis
Many choices are available for selecting printers, setting fonts and page margins, formatting dates, including company logo bitmaps, and adjusting information spacing relative to borders. You can select a subset of treatments, and select and rearrange data columns on your reports, so reports only list the information that you wish to include.
List ingredient information for pre-mix treatments, including the portion of the total rate contributed by each ingredient. Synonyms can also be printed for treatments, for uses such as listing common name in place of trade name on printouts.
Use the plot data view dialog box to develop a view of assessment data that is sorted in the order you want data to be presented. Within a plot data view, you can easily perform multi-level sorts such as sorting by assessment date within species. Hide all calculated or all original data columns with one command when creating the view. Once a view is created, print a data summary that automatically uses the current view.

Data Summary Reports

Validation lists, sometimes called lookup tables, are defined for nearly any data entry field. Items can be easily and quickly selected from these lists. Validation makes data entry much easier for inexperienced typists, helps insure uniformity, and nearly eliminates the chance of typing errors.
  • Use personal or master validation (lookup) lists for treatments, data headers, and site description data to speed input. Master lists are nearly unlimited in size.
  • Entry fields and prompts can display in different colors to indicate validated and required entry fields
  • Easily filter entries in large validation lists to display only those items of immediate interest
  • Quickly search validation lists for a specific word or phase using the Find command
  • Easily add or delete from validation lists in study editors
  • Can lock validation lists to prevent un-authorized users from making changes


The ARM is very user-configurable. There are many options to change report appearance, study editor views, and actions.
  • Treatment fields (columns) can be hidden on study editor and reports, and field sizes can be adjusted if needed.
  • Items in most validation lists can be added, deleted, or revised.
  • New rate units are added by GDM upon request.
  • Labels size and format is user-configurable for plot and container labels.
  • All reports can be copied to Word or Excel by a simple button click, offering full flexibility to change report formatting.


We at GDM believe that Electronic Data Exchange (EDE) provides important benefits for all researchers by defining a standard format for transferring data between researchers. To show our support and commitment to EDE, we continue to offer EDE export and import with ARM at no extra charge.
ARM exports and imports in studies in several EDE versions, and is compatible with other commercial trial data management software. Information can be imported from standard EDE formats used by cooperators into customized study formats used by crop protection companies.
