Background

Richard Hayes joined NSW Department of Agriculture* in 2000. He is an applied researcher with broad experience conducting field- and glasshouse-based research on a broad range of issues relating to pastures, perennial crops and soil fertility. The focus of much of his previous research has been in examining the productivity and sustainability benefits of incorporating perennial species into agricultural landscapes.

Richard currently leads Australia’s only research project in perennial grains which is testing the impacts of novel dual purpose perennial cereals on grazing sheep. This 5-year project commenced in 2018 and includes i) agronomic evaluation of perennial wheat lines, ii) an assessment of the productivity and health of sheep grazing perennial wheat, and iii) an evaluation of the impact of perennial wheat-based diets on meat quality.

Richard leads a second 5 year project examining the prospects for improving perennial forage legume adaptation in tablelands environments of south-eastern Australia through improved soil fertility. There are very few viable perennial legume species suited to these environments and species such as white clover, which are available, are inherently sensitive to drought. The soils across this region are typically highly acidic and of low fertility. Richard’s project examines the extent to which amelioration of these soil constraints will improve perennial legume persistence.

Richard is also leading an evaluation of annual forage legume species in the permanent grazing environments of south-eastern NSW under the P4Pastures project, examining ways to improve the phosphorus-use efficiency of grazed pastures. This project has identified serradella as a key species of interest and is presently examining the phenology and seed characteristics necessary to extend serradella into these new environments.

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
