Influence of Plant Growth Regulation on Canola Yield and Profitability under Irrigation locations
Aims

To examine whether experimental PGR (not commercially approved) application has any yield benefit in irrigated canola at different plant populations

Key messages

• Experimental PGR management (based on a gibberellin inhibitor) in irrigated canola resulted in significant differences in crop canopy height but no significant effect on seed yield irrespective of plant population.
• Reducing plant population did significantly reduce crop height at 80% flowering, however there was no difference in crop height at harvest due to plant population.
• The highest seedrate 100seeds/m2 of the TT hybrid produced significantly higher yields than lower seedrates when the effects of PGR treatments were averaged.
• There was no benefit in harvested seed yield although the canopy was more suitable for direct heading due to its shorter stature at harvest.
