GRDC Stubble Project

Wednesday 29 November 2017 heralded the final stubble project plot to be harvested at Northparkes Mine. The other two sites were at Tottenham and Mumbil Creek. These trials have been sown for five years under the GRDC funded initiative “Maintaining profitable farming systems with retained stubble in Central West NSW”. This project has explored the many variables with retaining stubble,...Read More

Managing yellow leaf spot in stubble retained systems in Central West NSW Locally specific guidelines and support for a proactive approach to disease management within retained stubble systems. Key messages: Stubbles carrying high loads of yellow leaf spot inoculum are the major source of crop infection. Decomposition or removal of stubble reduces inoculum.Yellow leaf spot is most severe when successive...Read More

Central West Farming Systems are conducting a nitrogen response trial at a variety of regional sites. The trials are investigating the impacts of different stubble treatments (imposed late in fallow) on nitrogen response, wheat yield and quality. The trials will allow CWFS to evaluate any interaction between pre-sowing stubble treatments and the timing of top dressing. During the year of...Read More

Research that was conducted in NSW and Queensland has indicated that inter row sowing has proven to be a useful tool when reducing the build up of crown rot innoculum within control traffic systems. In minimum till cropping system the fungus Fusarium pseudograminearum (crown rot) has become concentrated within the rows of the previous years winter cereal crop. Dr Steven...Read More

There are a range of benefits when it comes to using pre-emergent herbicides within your integrated weed management strategy for the year. The core benefits of pre emergent herbicides includes:  1# Pre-emergent’s offer an alternative mode of action 2# Reduces the selection pressure on post emergent herbicides 3# Eliminates the early season weed burden 4# Cost savings in the fallow where multiple knock...Read More
