The latest research on persistence of perennial rye-grass pasture under no or limited irrigation over summer was presented to a Katunga field day recently.
Three Agriculture Victoria representatives spoke about dairy forage research projects they are currently conducting at the Summer Survival of Pasture Field Day at Daryl Hoeys dairy farm.
The Murray Dairy event was attended by 22 people.
Kevin Kelly, Alister Lawson and Mary-Jane Rogers from Agriculture Victoria’s Tatura centre spoke about perennial rye-grass genetic gains and summer survival of perennial rye-grass.
When talking about the genetic gains of rye-grass, Dr Lawson said the purpose of this project was ‘‘to define the gains that have come from plant improvement and where these gains are coming from’’.
‘‘We are doing the trials here as northern Victorian summer temperatures are as high as any other place where rye-grass is grown globally,’’ Mr Kelly said.
‘‘We picked two (North Mooroopna and Terang) extreme environments where rye-grass is grown to stretch the boundaries to look for the source of the gains and the type of gains.’’
Dr Rogers talked about experiments done at Tatura, as well as on-farm sites at Katunga and Rochester, that involved irrigated and drought-affected paddocks.
