AES Circular 44

Abstract

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.Introduction -- Standard Bushel Weights and Conversion from English to Metric Units -- Part I: Climatic Data and Germplasm Evaluation: Tanana Valley Weather Summary: Table 1: Climatic Data for Delta Junction during the 1982 Growing Season, Table 2: Climatic Data for Fairbanks during the 1982 Growing Season; Barley Performance Trials: Table 3: Long-Term Average and Range of Yields for Barley Standard Varieties Grown at Fairbanks and Delta Junction, 1971-1982, Table 4: Barley Variety Trials Conducted at Delta Junction and Fairbanks during the 1982 Growing Season; Variety Descriptions: Table 5: Barley Varieties Tested at Fairbanks and Delta Junction, 1971-1982; Oat Performance Trials: Table 6: Long-Term Average and Range in Yields for Oat Standard Varieties Grown at Fairbanks and Delta Junction, 1971-1982; Table 7: Oat Variety Trials Conducted at Delta Junction and Fairbanks during the 1982 Growing Season; Variety Descriptions: Table 8: Oat Varieties Tested at Fairbanks and Delta Junction, 1971-1982; Spring Wheat Performance Trials: Table 9.
