Brassica juncea and canola (Brassica napus) in low rainfall South Australia - trials over the past several years, blackleg and new varieties locations
Aims

To compare Brassica juncea with B. napus and discusses where B. juncea could be grown in South Australia.

Key messages
  • Brassica juncea has the potential to be grown on a substantial area of low rainfall cropping country in South Australia with a likely area of up to 165,000 ha per year.
  • Production may be expected to vary from year to year based on the timing of the seasonal break.
  • Previous trials have shown that under low yield conditions, B. juncea can produce higher grain yields than canola.
  • In the past two years with mild, wet conditions canola has performed relatively better than B. juncea.
  • We are starting to see more blackleg occurring in low rainfall regions as the area sown to canola increases. It is not yet enough to cause problems but we need to keep our eye on it.
  • Even more canola varieties have been released that may be good options in low rainfall areas.
