Improving the water use efficiency of horticultural crops

NPIRD project CDH1

The results of this project show that there is considerable scope for improving the water use efficiency of fruit production in Australia. The two year project has sought to test the partial rootzone drying (PRD) irrigation method, originally developed for grapevines, in a range of woody perennial horticultural crops. The technique requires that both wet and dry rootzones are simultaneously created. Results with grapes, citrus and pears have given exciting results. (more)...

Improving water use efficiency by reducing groundwater recharge under irrigated pastures

final report

Approximately 65% of water extracted for irrigation in Northern Victoria and over 30% in the NSW Murray Valley is applied to pastures. In 1996, Murray Irrigation Limited (MIL) introduced a Total Farm Water Balance Policy which aimed to limit farm water use to sustainable levels and hence to reduce groundwater recharge to the district watertable. The dairy industry had some concerns with the original limit of 4 Ml per hectare and initiated discussions (more)...
