We at Gylling Data Management (GDM) create, market, and support ARM software for managing and summarizing agriculture research experiments.

  • ARM saves time creating trials, analyzing data, and producing the many reports required for successful and timely trial management.

  • ARM is a recognized and respected standard throughout the crop production and protection industry.

  • ARM is used by thousands of researchers in 75 countries worldwide (more than any other integrated research trial management software).
