    • Construction and Use of a Reindeer Fawn Separator for Injury Prevention

      Thompson, Bill; Dieterich, Robert (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-01)
      In 1985, members of the Applied Reindeer Research Project at the University of Alaska Fairbanks obtained and reviewed a Scandinavian instructional video1 on reindeer herding in Norway. This video described a structure that was developed and used by the Scandinavian reindeer industry to prevent injuries during corralling by segregating fawns from adults. The following is a description of how the fawn separator is built, how it works, and its current use in western Alaska.
    • Raising Orphan Reindeer Fawns Applied Reindeer Research Project

      Dieterich, Jamie K. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-12)
      Orphan reindeer fawns are often observed at summer handlings. Sometimes an abandoned fawn is found on the range. These fawns can be saved and raised for pets or for sale as live animals. There is an increasing demand for live reindeer to be shipped to locations outside Alaska. Tame reindeer adapted to a commercial diet can be a potential source of income for the herder as well as a rewarding project for the family. The following information is intended for reindeer herders in Alaska who do not have ready access to modem veterinary facilities or care.
    • Potato Variety Performance

      Carling, D.E.; Westphale, P.C. (Palmer Research Center, Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-04)
      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.
    • Air Transport of Alaskan Reindeer Applied Reindeer Research Project

      Dieterich, Robert A. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-12)
      This report describes one aspect of successful air transport developed over the past 20 years in Alaska
    • PLANNING A FOREST INVENTORY: GUIDELINES FOR MANAGERS OF ALASKA NATIVE LANDS

      Miller, Ronald K.; Gasbarro, Anthony F. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-10)
    • Nutrient Value of Alaskan Feedstuffs 1988

      Bruce, Leroy Ben; Herlugson, Mary Lou (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-04)
      Livestock rations should be balanced for many parameters including protein, and various minerals, and energy, to ensure that all required nutrients are present in the adequate amounts and proper relationships. Energy content is the primary consideration for balancing any farm animal’s diet because it is often the most limiting factor in animal performance. In Alaska, it is extremely important to test for major nutrients and then to balance rations because: 1) Alaska has longer, colder and wetter winters than those in the lower 48 states and consequently Alaskan animals have different nutrient needs. 2) Alaskan feedstuffs tend to be more variable in nutrient content than feeds grown in other states. After energy requirements, crude protein, calcium, phosphorus, and potassium are considered - and with the energy estimate - are the basis of the standard feed analyses performed by the Agricultural and Forestry Experiment Station (AFES) Service Laboratory feed testing section. Because all of these nutrients can vary greatly in the same feed, the Palmer Animal Sciences beef unit of AFES tracks the nutrient values of feed samples submitted to the AFES Service Laboratory. A summary of these values provides an indication of the types and values of feed available in Alaska. It also shows the variability in nutrient content of feedstuffs. Hopefully, this will stimulate the use of individual nutrient analyses for feeding livestock in Alaska.
    • POTATO VARIETY PERFORMANCE ALASKA 1987

      Carling, Donald E.; Rissi, Peter (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1988-03)
      A comparative yield trial with thirty-six 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 1987 growing season. The trial was conducted at the Matanuska Research Farm, located 6 miles west o f Palmer on Trunk Road. Nonirrigated trials have been conducted each year beginning in 1982, and irrigated trials were begun in 1985. Results of previous trials have been recorded in Circulars 49, 54, and 58, available at the Agricultural and Forestry Experiment Station offices in Fairbanks and Palmer. Varieties with a history of commercial production in the Matanuska Valley (including 'Alaska 114', 'Bakeking', 'Green Mountain', 'Kennebec', and 'Superior') are included and serve as a comparative base for newly developed varieties, numbered selections, or older varieties that heretofore have not been tested at this location. Varieties that com pare favorably with the above-listed standards may warrant some consideration by commercial growers. 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 nine locations throughout the state.
    • THE ROLE OF IRRADIATION IN FOOD PROCESSING: CAN IT BENEFIT ALASKA?

      Swanson, Ruthann B.; Lewis, Carol E.; Hok, Charlotte I.; Das, Debendra K.; Zarling, John P.; Workman, William G.; Logan, Robert R. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1988-03)
      Treatment of Alaska-produced food products by ionizing radiation may benefit the seafood and agricultural industries and the Alaskan consumer. A feasibility study to evaluate the potential social and economic benefits and risks as well as the costs of using the process in Alaska on Alaskan products is being coordinated by the Institute of Northern Engineering. A research and development project to determine effects on the quality o f Alaskan products could be the next phase in the introduction o f a new food-preservation technique to Alaska.
    • PERFORMANCE of CEREAL CROPS in the TANANA RIVER VALLEY of ALASKA 1986

      Wooding, F.J.; Hanscom, J.T.; Van Veldhuizen, R.M. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska, 1987-06)
      This is the eighth publication of grain performance trials in the Tanana River Valley. The first, published 7 years ago, included the results of spring cereal-variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. Beginning in 1980, the variety-test results were annual publications. This report, like last year’s, is a shorter version than the first 6 publications of the series. It reflects continued budget constraints caused by Alaska’s sagging economy.
    • RAPESEED PRODUCTION DEMONSTRATION IN INTERIOR ALASKA

      Arobio, E.L.; Quarberg, D.M.; Lewis, C.E.; Mitchell, G.A. (Agricultural and Forestry Experiment Station School of Agriculture and Land Resources Management University of Alaska-Fairbanks, 1987-07)
      Rapeseed is the oil-bearing seed from plants of the Brassica genus. It grows well in the cooler agricultural regions o f the world and for this reason has long been thought to be a promising crop for interior Alaska. Rapeseed has been grow n in India and China for thousands and in Europe for hundreds o f years (Bolton 1980). Its history in North America began in 1943 when a small quantity of seed was imported into Canada. In recent years, its production has been largely that from cultivars bred for production of seed low in erucic acid and glucosinolate content. Seed from these cultivars is referred to by the Canadian Rapeseed Industry as canola. Its qualities are desirable in the edible-oil market, the largest market for products from canola seed. Canada is now one of the world’s largest producers and is the world’s largest exporter o f rapeseed. The meal that remains after oil extraction is high in protein and is used as a supplement in livestock feeds. The whole seed can also be used as a feed supplement. Some cultivars o f rapeseed that are high in erucic acid are also grow n for use in plastics and industrial oils (Genser and Eskin 1979). In addition, forage rapeseed cultivars can be used as livestock pasture. Research concerning the production of rapeseed has been addressed by the Agricultural and Forestry Experiment Station (AFES) for several years. O f specific concern has been the selection of appropriate cultivars (Wooding et al. 1978), response to various nitrogen (N) rates, row spacings and seeding rates (Lewis and Knight 1987), performance in reduced-tillage systems in rotation with barley (Knight and Lewis 1986), the potential for frost seeding in late fall and early spring (Knight and Sparrow 1984) and response to boron (B) to enhance early seed ripening (Wooding 1985). In addition, in 1978 the Cooperative Extension Service (CES) began conducting seminars on production o f rapeseed for Alaskan farmers. In 1979 and 1980, CES employed Dr. J.L . Bolton, a rapeseed specialist from the University o f Alberta, in an extension capacity to give technical assistance to farmers on producing rapeseed (Bolton 1980).
    • Alaska’s Reindeer Program 1986 Report of the University of Alaska Reindeer Program: 1986 Report the Applied Reindeer Research Project

      Epps, Alan C. (Agricultural and Forestry Experiment Station School of Agriculture and Land Resources Management University of Alaska-Fairbanks, 1987-07)
      The University o f Alaska-Fairbanks reindeer program has existed under its current organizational framework since 1981. Program guidance across the three functions o f research, extension, and instruction continues to meet with support both internal and external to the university. The program ’s user group, the Alaska Reindeer Herders Association, is an ideal Land Grant/Sea Grant recipient for such guidance. Several major issues outlined by the Reindeer Herders Association’s first five-year plan have been addressed during the past few years. In most cases the university’s input has helped to resolve the association’s concerns. Currently a new five-year plan is being developed, and the university’s reindeer program is responding by redirecting its efforts toward emerging issues. This report identifies recent accomplishments in the reindeer program , continuing efforts, and projected areas of future effort.
    • Potato Variety Performance, Alaska 1998

      Carling, D.E.; Boyd, M.A. (Agricultural & Forestry Experiment Station; University of Alaska Fairbanks, 1999-02)
      A yield trial comparing 30 cultivars of potatoes (Solarium tuberosum L.) was conducted during the 1998 growing season at the University of Alaska Fairbanks, Agricultural and Forestry Experiment S tation ’s (AFES) Palm er Research Center, Matanuska Farm, located six miles west of Palmer, Alaska. A noteworthy change in design of this trial from previous years is the elim ination of a nonirrigated treatment. This change was made in response to grower requests that more emphasis be placed in other research areas. Also, the differences in yield between irrigated and nonirrigated studies, and thus the clear need for systems to supplement rainfall, has been well established by trial results from previous years.
    • Model to Evaluate Potential Production and Income Responses of Reindeer Herds under Different Management Strategies

      Finstad, G.L.; Prichard, A.K. (Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 1999-10)
      Free-range reindeer in western Alaska are managed for both velvet antler and meat production. Optimal management should maximize the income generated from both meat and antler production while managing the herd at levels below the carrying capacity of the range. Meat production precludes future antler production from harvested animals, therefore harvest decisions should reflect antler and body growth rates, current antler and meat prices, natural survival rates, and population demographics. We present a user-friendly computer model to generate estimates of net income under different harvest levels and market conditions. Input variables include sex- and agespecific survival rates, harvest levels, castration rates, antler weights, body weights, and recapture rates, as well as reproductive rates, fixed and variable costs, antler price, and meat price. Mark—Recapture analysis was used to estimate survival rates. The model was calibrated using reindeer herd records from 1984-1997. Output includes changes in herd size and composition over a thirty-year period, meat production, antler production, female: male ratio, and predicted net income. The model illustrates the sensitivity of herd size to female adult survival rates.
    • Gardening With Annual Flowers In Interior Alaska

      Wagner, Pat; Griffith, Marilyn; Matheke, Grant (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1987-04)
      This list of recommended annual flower varieties includes information on several hundred annual flower cultivars. The recommended varieties were selected from flowers grown in 1985 and 1986 at the Agricultural and Forestry Experiment Station Farm at the University of Alaska- Fairbanks. While this is by no means a complete listing of varieties suitable for Interior gardens, it does reflect many years of experience in annual flower production at the AFES farm. The methods used to evaluate the flowers and definitions for terms used in the listing can be found under Data Collection.
    • Annual Flower Plant Evaluations 1999

      Holloway, Patricia S.; Matheke, Grant E.M.; Van Veldhuizen, Jacob; MacDonald, Theresa; Van Whye, Eileen (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1999-11)
      The annual flower trials were planted from 30 May through 4 June, 1999 in the Perennial Landscape and All America Selections Display Garden of the Georgeson Botanical Garden (64°51N, 147°52W). Fairbanks silt loam soil was fertilized with 1 0 -2 0 -2 0 S (4 lbs per 100 sq feet, 195 g per sq meter) on 28 May. With the exception of dahlias, all flowers were grown as seedling transplants and were hardened off outdoors for one week prior to transplanting. Tuberous roots of dahlias were planted in containers five weeks prior to transplanting and were hardened off.
    • Potato Variety Performance, Alaska 1999

      Carling, D.E. (Palmer Research Center, Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 2000-02)
      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.
    • Annual Flower Evaluations 2000

      Holloway, Patricia S.; Matheke, Grant E.M. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, 2001-01)
      The annual flower trials were planted from 30 May through 2 June, 2000 in the Perennial Landscape and All America Selections Display Garden of the Georgeson Botanical Garden (64°51/N, 147°52'W ). Fairbanks silt loam soil was fertilized with 10-20-20S (4 lbs per 100 sq feet; 195 g per sq meter) on 28 May. With the exception of dahlias, all flowers were grown as seedling transplants, and were hardened off outdoors for one week prior to transplanting. Tuberous roots of dahlias were planted in containers five weeks prior to transplanting and were hardened off.
    • POTATO VARIETY PERFORMANCE ALASKA 1986

      Carling, D.E.; Rissi, P. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1987-02)
      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.
    • PERFORMANCE of CEREAL CROPS in the TANANA RIVER VALLEY of ALASKA 1985

      Wooding, F.J.; Hanscom, J.T.; Van Veldhuizen, R.M.; Rippy, A.J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska, 1986-01)
      This is the seventh publication of grain perform ance trials in the Tanana River Valley. The first, published 6 years ago, included the results of spring cereal-variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. Beginning in 1980, the variety-test results were annual publications. The length and content of this report is much less than for previous years. This is the result of a cost-saving measure to help cope with a shrinking budget.
    • A Survey of the Alaska Greenhouse Industry and Related Enterprises Results and Analysis

      Brown, Deborah M.; Holloway, Patricia S.; Kirts, Carla A. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1986-02)
      A list of commercial greenhouses, nurseries, interiorscape businesses, landscape contractors, florist businesses, and variety stores that sell plant products was developed in order to determine the scope of the horticulture industry in Alaska. The list identified 155 greenhouse, nursery, and interiorscape businesses along with 304 landscape contractors, 80 florist businesses, and 41 variety stores that sell plants. A questionnaire was used to determine the status of these types of enterprises including location, square footage of facilities, source of heating and lighting for greenhouses, number and type of employees, products purchased and/or produced, and total gross sales. The number of businesses responding to this survey totaled 135 and included 54 greenhouses and/or nurseries, 4 interiorscape businesses, 44 landscape contractors, 19 florists, and 14 variety stores. More than half of the greenhouse, nursery, and interiorscape businesses were started after 1976, and 40.4 percent of the businesses began as a hobby that was expanded into a commercial enterprise. Nearly all of the greenhouse operations had Quonset or even-span gable greenhouses covered with corrugated fiberglass or double-layer polyethylene. Most greenhouses were heated with natural gas or heating oil. The businesses that responded had a total of 413,476 square feet (ft2) of year-round heated greenhouse space, 266,900 ft2 of seasonally heated space, and 18,369 ft2 of nonheated space. The most commonly grown crops were flower­ing annual and vegetable bedding plants. The number of employees at the businesses with greenhouses was 678: 152 year-round, full-time employees; 85 year-round, part-time employees; and 441 seasonal employees, 150 of whom were hired only during the transplanting season. The estimated number of jobs available statewide in greenhouse, nursery, and interiorscape businesses totaled 1,559. Forty-four percent of the businesses with greenhouses reported gross sales of less than $25,000, while 5 businesses exceeded $1 million in gross sales. The estimated total gross sales for greenhouse, nursery, and interiorscape businesses in Alaska was $24,387,500.
