This research identified the plant traits most likely to determine differences in external critical phosphorus (P) requirements (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of pasture legume species. Understanding trait differences that affect critical P requirements of pasture legumes is important in providing confidence around field differences in external critical P requirement.

This research aimed to determine the external critical phosphorus (P) requirement (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of a range of pasture legume species under field conditions. This information can be used as a benchmark for soil testing and soil P fertility management on farms.

The purpose of this experiment was to apply Plant Growth Regulators (PGRs) to a high input durum wheat crop to
understand the impact of PGRs on standability and grain protein. The trial also included a variety split within a field

Four years of research have been conducted to determine if rice PIN uptake can be predicted using remote sensing from drones, aircraft and satellites as part of an ongoing Rural Industries Research & Development Corporation (RIRDC) research project. 

To evaluate the impact of late nitrogen application timings on wheat protein levels.

The aim of this experiment was to investigate the effect of two commonly used PGRs on root growth. It was hypothesised that if root growth modification occurred due to PGR application it would be a result of either the PGR altering the allometric balance between roots and shoots; a modification of the allocation of photoassimilates between the root and shoot as a consequence of inhibiting shoot growth; or a translocation of PGR from the point of application to the roots to directly influence root growth.

The aim of the trial was to assess the influence of PGR and nitrogen rates on the standability, head loss and yield of
an irrigated barley crop. We also wanted to observe the fit for PGR’s in a later planted crop with perceived yield
limitations due to season length.

The project has two components: an agronomy component that will assess the impact of varying surface irrigation management strategies (scheduling and frequency) on nitrogen use efficiency, water use efficiency and overall system profitability; and a hydrology component that will develop irrigation design criteria that will allow precise application of water in basin irrigation layouts, such as bankless channel systems, allowing flexible management to match recommendations from the project’s agronomy component.
