| Other trial notes |
In more recent cropping seasons several high wind events around the harvest period of lentil across southern Australia resulted in significant losses due to pod drop across a range a varieties. In preliminary trials at Curyo in 2019, significant variation was noted, with PBA HallmarkXT showing the worst susceptibility of released varieties (CIPAL1821 was noted to be one of the worst breeding lines). It has also been suggested that row spacing and direction could have an impact on the response, due to the way the crop forms the canopy, and thus the movement that occurs at maturity during high wind events. These trials looked at combing agronomic and genetic responses to minimise yield losses from pod drop at harvest. (Sister trial at Nhill) |
