Feed for the summer: summer-growing perennial grasses for Mallee mixed farms locations
Aims

To test the persistence and performance of summer-active perennial grasses in a Mallee environment and the potential for pasture cropping.

Key messages
  • Summer-active perennial grasses such as commercial Panic varieties have persisted, provided year-round groundcover and produced good quantities of pasture over several years in two field trials in the Mallee; growth rates and grazing potential are highest and most reliable in November and April.
  • The high level of winter dormancy can allow for opportunistic establishment of inter-row winter species (e.g. pasture cropping). In 2012, with low growing season rainfall, pasture-cropped wheat production was penalised; evaluation is ongoing.
