The effect of sowing time and variety on yield and oil concentration of canola (Brassica napus) locations
Aims

To investigate the effect of sowing time and variety on yield and oil concentration of canola (Brassica napus)

Key messages
  • The effects of sowing time and variety on yield and oil concentration of canola (Brassica napus) were investigated at Condobolin in 2002 and 2003.
  • Eight canola varieties and two Indian mustard varieties differing in maturity were established at four sowing times from early April to mid June.
  • Early sowing increased yield and oil concentration.
  • Yield and oil concentration declined with each delay in sowing time in both years.
  • Variety maturity type is not as important as early sowing.
