Four cultivars of phalaris were evaluated for their ability to survive a severe drought in 1994 in an existing grazing experiment at 2 sites near Canberra. The effect of rotational grazing and set stocking on persistence of phalaris measured as basal cover, pasture composition in spring and animal production from the pastures was assessed over the next 4 years. Basal cover of all cultivars declined sharply in 1994, but had recovered by August 1995 at a site with a relatively deep soil profile. Recovery was slower at a site with a shallower soil profile. Sirosa declined more in basal cover than Holdfast and Australian at the latter site. All of the cultivars survived the drought well but Sirosa may be more sensitive to overgrazing in drought. Compared with set stocking, rotationally grazed pastures had a higher (P |
