    Summary of 1993 Activities
    The fourth year of field work was completed in 1993 for the field-scale study of Best Management Practices (BMPs) for deficit irrigation and associated nitrogen fertilizer management on soils representative of the Garrision Diversion Unit. The "test site," selected withint the 5000-acre Test Area of the Garrison project, encompasses 160 acres of NW1/4, Sec. 29, T. 130 N, R. 59 W., in Dickey County of North Dakota. Approximately 132 of the 160 acres are irrigated by a center pivot irrigator (Figure 1). Herman Meyer owns the site, while farmer-cooperator Stan Hokana operates the site.

    Table 1 summarizes the activity that occurred at the site for project year 1993. Table 2 summarizes the activity that is planned at the site for project year 1994. Table 3 summarizes weather, nitrogen management, irrigation management, and yield information with coomparisons to Oakes Test Area (OTA) averages for the project history, i.e., the 1990 through 1993 seasons.
