Improving the water use efficiency of horticultural crops 2008-02-01T05:14:46Z 2009-07-10T03:46:32Z Improving the water use efficiency of horticultural crops NPIRD project CDH1 B Loveys, P Dry, R Hutton, P Jerie B Loveys, P Dry, R Hutton, P Jerie 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. PR990328 PR990328
