Tasmania – Feed year growth rate patterns

Pasture composition 

The measured and potential daily growth rates are for typical pasture mix of perennial ryegrass and cocksfoot with white and red clover in the high rainfall areas and grading to sub-clover in the lower rainfall areas. The measurements were taken over four years (1992–1995) at trial sites.
