Farm Table says:

GRDC and Riverine Plains Inc’s research has produced new information on how stubble management impacts dry matter accumulation, nitrogen uptake, frost risk and grain yield of subsequent crops.

What is the problem?

 This project is part of an overarching national initiative focusing on maintaining the profitability of stubble-retained systems. It has been designed to investigate, demonstrate and extend cultural practices that will assist growers adopt no-till stubble retention (NTSR) in medium and high rainfall zones.

What did the research involve?

The project has established four focus farms with large, commercial scale trials at Coreen, Henty, Yarrawonga and Dookie. The trials compare crop growth, frost and disease risk and yield under different stubble management techniques, including burning, mulching or incorporation of stubble as compared to leaving stubble standing. Supporting small scale trials focus on specific issues such as row spacing and cultivar selection, N timing and disease management.

What were the key findings?

The project is developing regional guidelines specific to the region, enabling growers and advisors to use rotational cultural control measures to enhance the sustainability of their NTSR farming systems.
