  • Smeenk, J.; Leiner, R.; Terry, G. (Alaska Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 2006-06)
    Twenty-two potato varieties were grown under irrigation at the AFES Palmer Research and Extension Center. The trial contained red, white, and russet-skinned varieties. The late-season rains provided ideal conditions for ...
  • Lewis, Carol E.; Pearson, Roger W. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1988-03)
    The Alaska Crop and Livestock Reporting Service of the United States Department of Agriculture has provided an annual publication detailing the quantity and value of agricultural products in Alaska since 1960. Although ...
  • Knight, C.W. (Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 1994-02)
    Barley is the principal grain crop in Interior Alaska. Oats are second in importance but are often harvested for hay rather than grain. Due to the short growing season (83–100 frost-free days), options for alternative ...
  • Geier, Hans (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 2004-01)
    In 2001, approximately eight acres of canola (Brassica campestris/rapa) was planted on the Agricultural and Forestry Experiment Station’s Delta Field Research Site. Three Polish varieties were planted, mainly Reward and ...
  • Geier, Hans (School of Agriculture and Land Resources Management, Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 2006-12)
    About one acre of Polish canola (Brassica rapa) was planted on the Agricultural and Forestry Experiment Station (AFES) Delta Junction research site in 2004 and 2005. Reward, a Polish canola variety, was planted. The Reward ...
  • Carling, Don E.; Conn, Jeff S. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-05)
    Weeds cause serious problems for commercial potato growers in Southcentral and Interior Alaska. Reductions in potato yields of 20 to 70 percent due to weeds have been observed in previous studies (Carling, unpublished ...
  • Matheke, Grant E.M.; Holloway, Patricia S.; Hanscom, Janice T. (Alaska Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 2006-03)
    The purpose of this research was to evaluate new commercial cultivars and compare them against one of our standards in an attempt to expand the choices of outdoor-grown tomatoes for interior Alaska.
  • Sparrow, Stephen D.; Conn, Jeffrey S. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1992-09)
    One of the major problems in the production of successful forage/green manure legume crops in Alaska is weed control. Many species of legumes are slow to establish from seeds as their seedlings are relatively ...
  • Carling, Don E.; Walworth, James L. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-06)
    Traditionally, commercially grown potatoes are hilled in the production cycle between emergence and closure of the canopy. Hilling is usually accomplished with disks, sweep shovels, or similar tools that lift soil from ...
  • Carling, D.E.; Michaelson, G.J.; Ping, C.L. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1987-06)
    Quantities of nitrogen (N) traditionally applied to lettuce fields by commercial growers range from lows of 80 to 120 lbs N/A (commonly 800 to 1200 lbs of 8-32-16 or 10-20-20) to rates as high as 250 lbs N/A. The higher ...
  • Gavlak, Raymond G.; Hall, Beth A. (School of Agriculture and Land Resources Management, Agricultural and Forestry Experiment Station, University of Alaska Fairbanks, 2002-06)
    Early perennial forage performance research was done in Alaska at a number of locations near the turn of the twentieth century, including Copper Center, Kenai, Sitka, and Rampart (Georgeson, 1899; Georgeson, 1901-1904). ...
  • Lewis, C.E.; Knight, C.W.; Pierson, B.J.; Cullum, R.F. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1987-07)
    The fertilizer application method used for producing small grains in interior Alaska is not always a matter of choice but of necessity. Farmers must fertilize, till, and seed a large acreage in a short time to complete the ...
  • Walworth, James L.; Gavlak, Raymond G.; Muniz, June E. (School of Agriculture and Land Resources Management, Agricultural and Forestry Experiment Station, 1990-12)
    Calcium (Ca), magnesium (Mg), and sulfur (S) are required for the growth and development of all higher plants. They are commonly referred to as secondary nutrients because they are less often limiting to plant growth than ...
  • Carling, D.E.; Michaelson, G.J.; Ping, C.L.; Walworth, J.L. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-02)
    Field studies previously conducted in the Matanuska Valley have determined that head lettuce production can be optimized by applying approximately 100 lbs per acre of nitrogen (N) as a fertilizer supplement when residual ...
  • Panciera, Michael T.; Gavlak, Raymond G. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1991-03)
    Husby and Krieg (1987) reported that average Alaskan forages were deficient in energy for beef cattle and protein levels were marginal for growing animals. Both the energy and protein of Alaskan forages are low for lactating ...
  • Walworth, James L.; Gavlak, Raymond G.; Muniz, June E. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-06)
    Nutrient uptake and physiological development in potato plants have been investigated in major potato growing regions, but comparable studies have not been conducted in high latitude areas such as the potato producing ...
  • Panciera, Michael T.; Sparrow, Stephen D.; Gavlak, Raymond G.; Larson, Warren E. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-06)
    Forage legumes have a high crude protein content and some residual nitrogen from these crops can be utilized by other species that follow legumes in crop rotations. Irwin (1945) compiled the results of early research ...
  • Helm, D.J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1991-04)
    An important component of revegetation is the seed mix used for soil stabilization. Although some trials of single grass species have been performed in southcentral Alaska in the past, new grass varieties have become ...
  • Helm, D.J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1992-09)
    Careful selection of plant species in a seed mix is important for successful reclamation. The main purpose of grass seed mixes is to establish a living plant cover to stabilize soils at least in the short term. Grasses ...
  • Masiak, Darleen; Sparrow, Stephen (School of Agriculture and Land Resources Management, Agricultural and Forestry Experiment Station, 1990-12)
    Short growing seasons in interior Alaska, averaging 90 days in Fairbanks, are a major factor affecting crop production. In the past, volunteer germination of seed from previous years crops has been observed in the ...
