ryegrass number

Project No.: DAW 672 Paper reviewed by: David Minkey and Abul Hashem Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 20.. The negative impact of Raptor and Spinnaker on herbage production observed in the 4 advanced breeding lines (Crop Updates 2004) was not reflected as lower seed set... Overall, 2,4-D and Gramoxone were the most damaging to legume seed production; this reflected the impact of these treatments on herbage production (Crop Updates 2004)...

One of the most effective weapons in the battle against annual ryegrass is growing a competitive crop... The outcome of Project ACR2/4 was assessed from this viewpoint over its eight-year life... Clover pasture - ST 0 0 36.3* 68 2000 - - 24/6 - Westonia wheat (100) 0 0 2.61 316 2001 SB C 6/6 - Arrino wheat (100) 0 0 3.62 726 2002 SB C 10/6 - Westonia wheat (100) 8 8 1.42 186 2003 NB - 2/6 - Arrino wheat (100) 8 8 3.58 541 2004 SB - 1/6 - Westonia wheat (130) 10 5 3.36 315 8 year cumulative 68 2137 w= kg ha -1wool the excellent result within this block is clearly linked to two major factors: o a generous period of time out of crop presenting an opportunity for a significant weed break...

For the past five years, through the GRDC-funded Focus Paddock project, researchers at the Department of Agriculture and Food, WA, have been monitoring the impact of this changing rotation mix on long-term productivity... "The lupins provide sheep feed sourced from our property, which reduces the risk of introducing weeds, and they also reduce nematode levels while adding nitrogen to the soil," Ben says... Ben has been involved with the Focus Paddock monitoring project for six years and says it has been fantastic to have the local DAFWA researchers undertake disease, soil and herbicide-resistance tests over time...
