      When growers in the Susitna Valley and later in the Pt. MacKenzie area of southcentral Alaska inquired as to the feasibility of growing rapeseed, we decided to determine the crops suitability and performance by conducting a field experiment. Bolton (1980) had attempted to predict the feasibility of producing rapeseed in Alaska's interior, but no research had been done in southcentral Alaska. We conducted one study from 1979 through 1981 on Rabideux silt loam (pH 5.1) near Trapper Creek and another from 1982 through 1984 on Kashwitna silt loam (pH 5.4) on the University of Alaska' s research tract in the Pt. MacKenzie area. The first area had been cleared prior to 197 8. This area was rototilled and roots removed in September 1978. The second area was on a tract cleared during the winter of 1981. After clearing, rotary plowing was done twice on the area. During the summer of 1981, roots were removed , and a field cultivator was used twice to loosen and bring roots to the surface.
