To demonstrate and quantify the plant establishment penalty of seeding canola into deep ripped soil, the loss of plants by deep ripping early post emergent (EPE), and to check if delaying deep ripping until EPE still produces a yield boost compared to ripping in typical summer conditions.
• There was no yield benefit to early post emergent ripping at 1, 3, or 6 weeks following seeding.
• Plant establishment and grain yield was reduced when ripped 1 week after sowing.

This project (WMG1803-002SAX) is a GRDC investment that is led by the West Midlands Group and this site is managed by the Liebe Group. This site is one of four trial sites across the Wheatbelt that has investigated the use of early post emergent (EPE) deep ripping on grain yield. Thank you to the Hirsch family for hosting the trial site. |
