This report summarizes the vegetable-variety evaluations of the Horticulture Department of the University of Alaska, Fairbanks, 1983. Variety trials were all conducted at the Agricultural Experiment Station's research farm at Fairbanks. The objective of this research is to select varieties of vegetables that are adapted to this environment. It also identifies types whose adaptability may be improved through development of improved cultural techniques. The selection effort is directed at finding varieties useful to both the commercial growers and home gardeners.Introduction -- Table 1: Climatic Data for the Fairbanks Growing Season: 1982, 1983 and the Long-Term Average -- Table 2: Broccoli Variety Trials, Upland, 1983 -- Table 3: Brussels Sprouts Variety Trials, Upland, 1983. -- Table 4: Cabbage Variety Trials, Upland, 1983 -- Table 5: Carrot Variety Trials, Bottomland, 1983 -- Table 6: Cauliflower Variety Trials, Upland, 1983 -- Table 7: Celery Variety Trials, Upland, 1983 -- Table 8: Cucumber Variety Trials, Upland, 1983 -- Table 9: Egplant Variety Trials, Upland, 1983 -- Table 10: Green Pea Variety Trials, Bottomland, 1983 -- Table 11: Crisphead Lettuce Variety Trials, Bottomland, 1983 -- Table 12: Pepper Variety Trials, Upland, 1983 -- Table 13: Potato Variety Trials, Bottomland Peat, 1983 -- Table 14: Pumpkin Variety Trials, Upland, 1983 -- Table 15: Snapbean Variety Trials, Upland, 1983 -- Table 16: Summer Squash Variety Trials, Upland, 1983 -- Table 17: Winter Squash Variety Trials, Upland, 1983 -- Table 18: Sweet Corn Variety Trials, Upland, 1983 -- Table 19: Tomato Variety Trials, Upland, 1983 -- Table 20: Container Tomato Variety Trials, 1983 -- Table 21: Miscellaneous Vegetables Tested -- Seed Source

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.Introduction -- Methods: Bedding Plant Production, Field Conditions, Weather Conditions, Data Collection -- List of Recommended Annual Flower Varieties -- Photo Section -- Appendix 1.

This report summarizes the vegetable variety evaluations of the Horticulture Department of the University of Alaska, Fairbanks, 1979. Variety trials were conducted at the Agricultural Experiment Station’s research farm. The objective of this research is to select varieties of vegetables that are adapted to this environment. It also identifies types whose adaptability may be improved through development of cultural techniques. The selection effort is directed at finding varieties useful to commercial and home garden growers.Varieties are chosen for inclusion in the variety tests on the basis of their description, their latitude of origin, and the record o f the plant-breeding program for producing kinds that have previously been found adapted. Standard recommended varieties are included for comparison. In the past, the vegetable variety evaluation program has been responsible for a continuous improvement in yields, quality, and dependability for many vegetable crops. Our philosophy is to depend upon the many existing plant-breeding programs instead of investing in an expensive, on-site, plant-breeding program . Progress can be made more rapidly by selection than by breeding.Introduction -- Growing-Season Summary: Table 1: Rainfall by Month During the 1979 Growing S e a s o n; Table 2: Broccoli Variety Trials, Upland, 1979; Table 3: Cabbage Variety Trials, Upland, 1 9 79; Table 4: Carrot Variety Trials, Bottom land, 1979; Table 5: Cauliflower Variety Trials, Upland, 1979; Table 6: Cucumber Variety Trials, Upland, 1979; Table 7: Green Pea Variety Trials, 1979; Table 8: Lettuce Variety Trials, Bottom land, 1979; Table 9: Pepper Variety Trials, Upland, 1979; Table 10: Potato Variety Trials, Bottom land, 1979; T able 11: Pumpkin Variety Trials, Upland, 1979; Table 12: Snapbean Variety Trials, 1979; Table 13: Squash, Summer Variety Trials, Upland, 1979; Table 14: Squash, Winter Variety Trials, Upland, 1979; Table 15: Sweet Corn Variety Trials, Upland, 1979; Table 16: Tomato Variety Trials, Upland, 1979; Table 17: Tomato Variety Trials Without Plastic Mulch, Upland, 1979; Miscellaneous Vegetables Tested; Seed Sources

Revised April 1991 by Grant E.M. Matheke, Patricia J. Wagner, and Patricia S. Holloway; Reprinted by Cooperative Extension Service, University of Alaska Fairbanks, and U.S.D.A. Cooperating. Publication 300C-00235A technique for growing high-yielding, everbearing strawberries with clear polyethylene (plastic) mulch and row covers has been developed at the Agricultural and Forestry Experiment Station at Fairbanks. This technique eliminates the long delay from planting to fruiting that occurs with other culture systems and it has created an interest in commercial production and an increased home-garden effort in Alaska. The production system involves planting nursery plants each season as early as possible through clear polyethylene mulch, using row covers for the early part o f the season. Using this technique, harvest begins about July 15 and extends until freeze-up, com pared to a production season from about July 10 to July 28 for hardy types o f strawberries such as Toklat or Pioneer. This system produces clean fruit, easy to pick and relatively free from fruit rot. The harvest season can be extended in the fall by again using the row covers for frost protection

Trials were begun in 1989 at the Georgeson Botanical Garden (64°51’N, 147° 52’W, elevation 475 feet; 136 meters) to evaluate the hardiness and ornamental potential of trees, shrubs, and herbaceous perennial ornamentals. Woody ornamentals are tested for 10 years, and herbaceous perennials for five years. This report is the first summary of perennials that have survived the trial period with a winter hardiness rating between zero and 2.5. Each plant in the trial is evaluated annually for winter injury and rated on a scale of zero through four. A zero rating denotes no visible injury, and four is death. A score of 2.5 and lower indicates the plant grew well in the Garden. It may have shown symptoms of winter injury but recovered in subsequent seasons. The species and cultivars listed in Table 1 are recommended for further trial throughout Interior Alaska. Plants are grown on a south-facing slope in Fairbanks silt loam soil. The plots have been cultivated since about 1910. All plants receive full sun except those located in the shade house. Plants receive supplemental irrigation, mostly hand weeding, and an annual application of 500 lb per acre (560.5 kg/ha) 10-20-20S fertilizer. Lilies receive 1500 lb (1,681.5 kg/ha) per acre of the same fertilizer. No plant receives winter protection such as mulches, wind barriers or snow fences. Weather data are compiled annually from U.S. Weather Service station (elevation 475 feet; 136 meters) located approximately 350 feet (105 meters) west of the Garden. A summary of pertinent weather statistics is shown in Table 2

In 1989, a systematic evaluation of woody and herbaceous perennial landscape plants was begun at the University of Alaska Fairbanks Georgeson Botanical Garden (64°51’N, 147°52’W). These evaluations were expanded to include annual flowers in 1992 and ferns in 1993. The purpose of this research is to identify hardy perennials capable of surviving in subarctic environments; to evaluate the ornamental potential of perennials and annuals; and to fulfill a growing demand for information on landscape plant materials by homeowners, commercial growers, and landscapers.Introduction -- Explanation of Plant Evaluation Tables -- Table 1.
