  • Mitchell, Wm. W.; Mitchell, G. Allen (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1986-02)
    This trial concentrates on the effects of varying rates of P with N and K supplied in amounts judged to be ample for establishment of perennial grasses. The results indicated that, by seeding sufficiently early and ...
  • Mitchell, Wm. W.; Mitchell, G. Allen; Helm, D. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska-Fairbanks, 1987-05)
    Three perennial grasses were established on Kashwitna silt loam at Pt. MacKenzie in 1985 to test their responses to different rates o f phosphorus (P) fertilization. Laboratory studies with a number o f Alaskan soils have ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Mitchell, W.W. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1989-03)
    Trials conducted with entries of oats, barley, and triticale on the university tract in 1987 and 1988 provided the first research information on triticale for forage use at Pt. MacKenzie. Triticale is a hybrid resulting ...
  • Dofing, S.M.; Blake, S.A.; Wolfe, R.I. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-02)
    Favorable climatic conditions for barley production in 1989 at the Matanuska Research Farm resulted in exceptionally high grain yields. Mean grain yield for cultivars in this test was 92.5 bushels per acre (Table 1). A ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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, Dorothy J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-06)
    Long-term goals of revegetation include the reestablishment of diverse, self-reproducing plant communities suitable for desired post-mining land uses. In Alaska, these uses include habitat for moose and other wildlife. ...
  • Sparrow, Stephen D.; Cochran, Verlan L.; Sparrow, Elena B. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-11)
    Legumes are notable for their ability to convert atmospheric dinitrogen into forms of nitrogen which are usable by plants. This is done in association with bacteria (called Rhizobium) which inhabit nodules of the plant ...
  • 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 ...
  • 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 ...
  • Dofing, S.M.; Blake, S.A.; Wolfe, R.I. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1990-12)
  • 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 ...
  • Matheke, Grant E.M.; Holloway, Patricia S.; Wagner, Patricia J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1991-04)
    Cold soils during the short growing season in interior Alaska often limit growth and prevent the maturing of many field-grown warm season crops such as tomatoes, peppers, cucumbers, pumpkins and sweet corn. Clear ...
  • Helm, D.J. (Agricultural and Forestry Experiment Station, School of Agriculture and Land Resources Management, University of Alaska Fairbanks, 1991-04)
