Abstract
The effects of trickle and furrow irrigation were determined on yield and growth of the wine grape `Shiraz' in the hot arid climate of Griffith, N.S.W. Daily trickle irrigation applied at 0.4 the rate of class A pan evaporation (crop factor=0.4) produced similar yields to furrow irrigated vines with crop factor 0.5. Daily trickle application with crop factor of 0.2 decreased yield by 16%. Applying similar amounts of water daily or every second day by trickle had similar effects on yield. Water stress up to veraison significantly reduced berry size, the yield component most sensitive to water stress.
