Abstract

Fifty-five rapeseed (Brassica napus L.) cultivars were evaluated between
1982 and 1987 on a Norfolk loamy sand (fine, loamy, siliceous, thermic Typic Paleudult)
near Florence, South Carolina. The average seed yield (1,590 kg/ha or 1,420 pounds/acre)
was comparable to that at other southern locations where rapeseed is grown as a winter
annual, but it was lower than in the Pacific Northwest, where the crop is grown as a
true biennial. Assuming a contract price of $0.2011cg ($0.09/pound), estimated gross returns
for rapeseed would be about $320/ha 0130/acre). For conservation purposes, the crop
may be more valuable because of its potential to reduce soil erosion; rapeseed provides
soil surface cover at an earlier date than winter wheat (Triticum aestivum L.). Results
of this evaluation suggest that additional research is needed to evaluate rapeseed as a winter
forage and/or cover crop for soil erosion control.
