TIA is participating in a national project to help optimise the productivity and profitability of high input cropping systems in the High Rainfall Zone (HRZ).

Research Fellow Dr Angela Merry said trials were sown at TIA’s Cressy-based Research Farm at various times during 2017, with the aim of determining whether long season canola varieties are better suited to the HRZ than their short and mid-season counterparts.

This project also includes trials in Victoria, the Australian Capital Territory, South Australia and Western Australia.

"Tasmanian data provides an important insight into the phenology, physiology and yield performance of canola lines. The unique environment down here, with different day-lengths and temperatures, helps tease apart our understanding of what drives yield in the HRZ for canola," Dr Merry said.

In addition to the canola trial, TIA researchers are also exploring the radiation use efficiency of wheat lines with varying degrees of leaf erectness in trials sown at Cressy through the same research project this season.

"The thinking is that wheat lines with erect instead of prostrate leaf structure might be better suited to the HRZ because they capture more solar radiation which may potentially increase grain yields," Dr Merry said.

The research is funded by Grains Research and Development Corporation (GRDC) and is led by the Victorian Department of Environment, Land, Water and Planning.
