Other trial notes |
In recent years, canola has proven to be a profitable break crop for the Upper North. Successful crop establishment is critical in achieving maximum yield potential. Typically, about 40-60% of sown canola seeds establish as plants, which is quite low compared to cereals (typically 80%). However, if conditions for canola are favourable, establishment can be as high as 80%. Being a small seed, canola is more vulnerable to poor establishment caused by inadequate seed to soil contact, margi |
