A yield trial comparing 30 cultivars of potatoes (Solatium tuberosum L.) was conducted during the 1999 growing season at the University of Alaska Fairbanks, Agricultural and Forestry Experiment Station’s (AFES) Palmer Research Center, Matanuska Farm, located six miles west of Palmer, Alaska. Similar to 1998, this trial included irrigated but not irrigated treatments. Data from previous studies has documented the consistent need for irrigation as well as the magnitude of increases in yield that can be realized through irrigation

Circular 58

A comparative yield trial with 44 named varieties and numbered selections of potatoes was conducted at the University of Alaska-Fairbanks, Agricultural and Forestry Experiment Station’s (AFES) Palmer Research Center during the 1986 growing season. This yield trial is the continuation of a potato variety testing program initiated in 1982. The trial again was conducted at the Matanuska Research Farm, located on Trunk Road near Palmer. Nonirrigated trials have been conducted each year beginning in 1982, but irrigated trials were not initiated until 1985. Results of previous trials are recorded in Circulars 49 and 54, available at the Agricultural and Forestry Experiment Station offices in Fairbanks and Palmer. As in past years, varieties with long production histories in Alaska (Alaska 114, Bakeking, Green Mountain, Kennebec, Superior) are included and serve as a comparative base for newly developed varieties or older varieties that in the past have escaped testing at this location. Varieties that compare favorably with the above listed standards may warrant some consideration by commercial growers. In continuance of a program that was initiated in 1985, abbreviated versions of the AFES potato yield trial were conducted at locations in various parts of the state. These off-station trials again were made possible by the willingness of cooperators to plant, tend and harvest the crop. The seven off-station sites include several where comparative testing of potato varieties has not been reported previously.Introduction -- Matanuska Farm Yield Trials: Cultural Practices - Environmental Conditions, Results, Discussion -- Trials at Other Locations in Alaska: General Procedures, Specific Site Information: Ambler, Copper Center, Delta Junction, Fairbanks, Kake, Kodiak, Noorvi

Circular 49

A program of field research relating to the commercial production o f potatoes was initiated in 1982 at the University of Alaska Agricultural Experiment Station ’s research center in Palmer. T he experimental fields are located at the Matanuska Research Farm on Trunk Road near Palmer. This program is a modified continuation of a potato research program initiated more than 30 years ago by D r. C .H . Dearborn. Whereas the major emphasis of D r. Dearborn ’s potato program w as variety development and testing, the major emphasis here is study o f general cultural practices, disease development and control, and the comparative evaluation (yield trials) o f potato varieties having commercial potential. Plans call for the comparative evaluation of thirty to forty named varieties or numbered selections each year. Varieties are selected for testing on the basis o f yield potential, general quality characteristics, and disease resistance. An attempt is made to include all varieties grow n commercially in the state, newly developed varieties from breeding program s in the U .S ., Canada, and elsewhere, as well as established varieties that have yet to be thoroughly tested in this environment. Commercial varieties with locally proven “ track record s ," such as Alaska 114, Bakeking, Green Mountain, and Superior will serve as a comparative base for m ore recently introduced varieites. New varieties will be tested for 4-5 years before being dropped , kept for further study, or recommended to commercial growers. Summarized in this circular are the results o f three years o f variety trials (1982, ’83, and ’84). Also included are summaries of environmental conditions at or near the experimental test site and some detailed information about several locally grown commercial varieties.Introduction -- Weather Data Summary: 1982 -- Weather Data Summary: 1983 -- Weather Data Summary: 1984 -- Yield Data Summary -- Variety Descriptions -- See

A comparative yield trial with 24 named varieties and numbered selections of potatoes was conducted at the University of Alaska Fairbanks, Agricultural and Forestry Experiment Station’s Palmer Research Center during the 1988 growing season. The trial was conducted at the Matanuska Research Farm, located six miles west of Palmer on Trunk Road. Nonirrigated trials have been conducted annually since 1982, and irrigated trials started in 1985. Results of previous trials have been recorded in AFES Circulars 49, 54, 58 and 65. These circulars are available at the Agricultural and Forestry Experiment Station offices in Fairbanks and Palmer.Introduction -- Matanuska Farm Yield Trials: Cultural Practices - Environmental Conditions, Results and Discussion; Trials at Other Locations in Alaska: General Procedures; Specific Site Information: Ambler, Delta Junction, Kake, Kenai - Soldotna, Kodiak, Kotzebue, Palmer, Pt.

Circular 77

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.Introduction -- Matanuska Farm Yield Trials: Cultural Practices and Environmental Conditions, Results and Discussion -- Trials at Other Locations in Alaska: General Procedures, Specific Site Information: Delta Junction, Fairbanks, Homer, Kenai - Soldotna, Kodiak, Kotzebue -- List of Table

A yield trial comparing 45 cultivars of potatoes (Solanum tuberosum L.) was conducted during the 1997 growing season at the University of Alaska Fairbanks, Agricultural and Forestry Experiment Station’s (AFES) Palmer Research Center, Matanuska Farm, located six miles west of Palmer, Alaska. Varieties with a history of commercial production in the Matanuska Valley (Alaska 114, Bake-King, Green Mountain, and Superior) were included to serve as a comparative base for newly developed varieties or older named varieties that have not been tested at this location. Russet Burbank, the variety most widely grown in the United States, also was included to broaden the base of comparison although past trials have demonstrated its unsuitability for this area. Varieties that compare favorably with the above listed local standards may warrant consideration by commercial growers. Nonirrigated trials have been conducted annually since 1982 whereas irrigated trials were initiated in 1985. Results of these trials were published in AFES Circulars and are available at AFES offices
