LUCERNE IN THE PUMICE COUNTRY

Abstract

Eleven years of experimentation ha've resulted in certain establish ment procedures being recommended and it has been shown that direct drilling of lucerne into chemically killed turf has given yields comparable with notmal cultivation methods. Maintenance topdressing trials have shown responses to increased quantities of potash, intermittent responses to sulphur, conststent responses to lime, and fleeting responses to boron. A grazing experiment with four lucerne varieties is described where increased yields have been obtained from a comparison of haying and grazing over production from a pure hay stand.
