| | PRD in grapes |
 | | As discussed earlier, PRD, or Partial root-zone drying, is an irrigation method developed in Australia, in which crops are irrigated one side at a time, leaving the other side dry, under mild water stress. |
 | | This finding is somewhat unusual since with what we know about PRD as a method requiring alternation of the drip line between both sides of the vine row, it would be expected that the 50% control group would behave in a manner more similar to the 100% control crops than to the PRD treated crops. |
 | | Thus, studies that demonstrate the positive influences of PRD on crop quality and water reduction are by no means bogus, however, implementing deficit irrigation on the same crops are likely to bear very similar results. |
