Aims
Investigate the effect of row spacing up to 66cm in two hybrid varieties at two different seeding rates to determine if row spacing or plant density can ameliorate the effect of sclerotinia stem rot, with or without fungicide application.
Key messages
Sclerotinia disease ratings were low in this trial as is expected in a season with a dry and late start (Bennett et al. 2018) but there was more disease in the Hyola 404 at the higher plant density than the other treatments.
Pioneer 43Y23 had significantly more branching than the Hyola 404 and a reduced length to the first branch. There was no significant difference in plant height between the two varieties but stem diameter was narrower in Hyola 404 than Pioneer 43Y23
Overall, the plant architecture dimensions or row spacing trial did not indicate a mechanism for increased or reduced disease control.
Grain yields decreased with increasing row spacing and reducing plant density.
This trial demonstrates that refining the agronomic package for wide row spacing in canola could lead to reduced up front and in season input costs
