| Summary: | A comparative yield trial with 45 named varieties and numbered selections of potatoes was conducted during the 1989 growing season at the University of Alaska Fairbanks, Agricultural and Forestry Experiment Station's (AFES) Palmer Research Center, Matanuska Research Farm, located six miles west of Palmer on Trunk Road. Nonirrigated trials have been conducted annually since 1982 and irrigated trials were begun in 1985. Results of previous trials are recorded in AFES Circulars 49, 54, 58, 65 and 71. These circulars are available at the Agricultural and Forestry Experiment Station offices in Fairbanks and Palmer. Also included in this report are the results of abbreviated versions of the AFES potato yield trial that were conducted by cooperating individuals and agencies at six locations in Alaska. Varieties with a history of commercial production in the Matanuska Valley (including Alaska 114, Bake-King, Green Mountain and Superior) are included and serve as a comparative base for newly developed varieties, numbered selections or older varieties that have not been tested at this location. Varieties that compare favorably with the above listed standards may warrant consideration by commercial growers.
