• PERFORMANCE of CEREAL CROPS in the TANANA RIVER VALLEY of ALASKA 1981

      Wooding, F.J.; McBeath, J.H.; Hanscom, J.T.; Van Veldhuizen, R.M.; Delucchi, G.M. (Agricultural Experiment Station, School of Agriculture and Land Resources Management, University of Alaska, 1982-03)
      This is the third publication in this form at on grain performance trials in the Tanana River Valley. The first, published two years ago, included the results of spring cereal variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. The second, published one year ago, contained the test results from the 1980 growing season. Included in this report are a weather summary, the 1981 variety-test results, and a plant-disease section. Previous work with grain variety testing has shown that individual varieties do not perform the same when grown under different conditions. The yield a variety produces can be influenced by crop rotation, soil pH, fertilizer rate, tillage practices, rainfall distribution and amount, seeding rate, planting date, and many other factors. Each variety has its own particular set of growing conditions under which it best performs. For example, in the very same field, a variety that performs well on summer-fallow land may do poorly when planted on stubble land.
    • PERFORMANCE of CEREAL CROPS in the TANANA RIVER VALLEY of ALASKA 1982

      Wooding, F.J.; McBeath, J.H.; Frost, S; Hanscom, J.T.; Van Veldhuizen, R.M.; Delucchi, G.M. (Agricultural Experiment Station, School of Agriculture and Land Resources Management, University of Alaska, 1983-02)
      This is the fourth publication in this form at on grain performance trials in the Tanana River Valley. The first, published 3 years ago, included the results o f spring cereal-variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. The variety-test results from the 1980 and 1981 growing season were annual publications. Included in this report are a weather summary, the 1982 variety-test results, and a plant-disease section. In 1982, the variety-testing program at Delta Junction was moved from Lee Fett’s farm in the Clearwater area to the University o f Alaska Research Field in the Delta Barley Project area. The new site is situated on recently cleared land. This should provide a more representative basis for variety evaluation for development of new lands. Many thanks are extended to Mr. Fett for his generosity and cooperation in allowing the Agricultural Experiment Station the use o f his land for m ore than a decade.
    • PERFORMANCE of CEREAL CROPS in the TANANA RIVER VALLEY of ALASKA 1984

      Wooding, F.J.; McBeath, J.H.; Frost, S.; 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, 1985-08)
      This is the sixth publication in this format on grain performance trials in the Tanana River Valley. The first, published 5 years ago, included the results o f spring cereal-variety tests conducted at Fairbanks and Delta Junction during the 1978 and 1979 growing seasons. The variety-test results from the 1980, 1981, 1982, and 1983 growing seasons were annual publications. Included in this report are a weather summary, the 1984 variety-test results, and a plant-disease section.
