Dairying is the largest irrigated industry in northern Victoria, in terms of water used, irrigated area and revenue generated (Meyer 2005). However, irrigation water available to the dairy industry for growing pastures and forages is likely to be reduced in the next 5 years. There is little comparative data available on the water use efficiency of forages for dairy production. These data would be useful to dairy farmers aiming to optimise their forage production under conditions of limited water availability.
