Pasture mixes with lucerne (Medicago sativa) increase yields and water-use efficiencies over traditional pastures based on subterranean clover (Trifolium subterraneum)

M. R. McCaskill, M. C. Raeside, S. G. Clark, C. MacDonald et autres

Pastures sown to lucerne (Medicago sativa L.) with a perennial non-legume could increase feed supply relative to traditional pastures based on subterranean clover (Trifolium subterraneum L.). Such mixtures might also be preferable to pure lucerne pastures, which are prone to weed invasion. …

Field Evaluation of Cocksfoot, Tall Fescue and Phalaris for Dry Marginal Environments of South‐Eastern Australia. 1. Establishment and Herbage Production

S. G. Clark, Zhongnan Nie, R. A. Culvenor, C. A. Harris et autres

Abstract Newly developed candidate cultivars of cocksfoot (Dactylis glomerata L.), phalaris (Phalaris aquatica L.) and tall fescue (Festuca arundinacea Schreb. = syn. L. arundinaceum (Schreb) Darbysh.) were evaluated over four years for persistence and productivity against current commercial cultivars in small plots …

Field Evaluation of Cocksfoot, Tall Fescue and Phalaris for Dry Marginal Environments of South‐Eastern Australia. 2. Persistence

R. A. Culvenor, S. G. Clark, C. A. Harris, Richard C. Hayes et autres

Abstract Perennial grasses provide forage and environmental benefits in the agricultural systems of southern Australia, but persistent cultivars are lacking for the lower rainfall inland margins (<600 mm average annual rainfall). Potential new cultivars of cocksfoot (Dactylis glomerata L.), tall fescue (Festuca …

Response of lucerne and chicory mixes to a rare high summer rainfall event in western Victoria

M. C. Raeside, S. G. Clark, M. R. McCaskill, DL Partington et autres

Two experiments were conducted at Hamilton, Victoria, Australia to test the hypothesis that sowing pastures with lucerne ( Medicago sativa L.) or chicory ( Cichorium intybus L.) increases dry matter (DM) production and nutritive characteristics during summer and autumn, relative to equivalent …

Summer-active perennials in pasture systems improve seasonal pasture distribution without compromising winter-spring production

G. N. Ward, S. G. Clark, Gavin Kearney, M. R. McCaskill et autres

Improved dryland pastures for sheep and beef cattle production in south-western Victoria are typically based on summer-dormant cultivars of perennial ryegrass (Lolium perenne L.) or phalaris (Phalaris aquatica L.). These are highly productive in spring but exhibit low accumulation rates over summer–autumn. …

Can summer-active perennial species improve pasture nutritive value and sward stability?

S. G. Clark, G. N. Ward, Gavin Kearney, A. R. Lawson et autres

Although generally well adapted and productive, the summer-dormant perennial pastures of southern Australia do not provide a year-round, high nutritive value feed base, they fail to respond to summer rainfall, and they are inefficient in using stored soil water, which can contribute …

Manipulating livestock grazing to enhance native plant diversity and cover in native grasslands

Jaimie Mavromihalis, Josh Dorrough, S. G. Clark, Vivienne Turner et autres

Temperate perennial grasslands globally have been subject to extensive biodiversity loss. Identifying livestock grazing regimes that maintain and enhance the diversity and cover of native plant species in these ecosystems remains a key challenge. The responses of vegetation to different sheep grazing …

A review of summer‐active tall fescue use and management in Australia's high‐rainfall zone

M. C. Raeside, Michael Friend, R. Behrendt, A. R. Lawson et autres

Abstract Throughout many areas of Australia, climatic conditions create a unique challenge for pasture producers due to the combined effects of heat and moisture deficit stress over summer/early autumn, and cold‐temperature stress with transient waterlogging over winter and early spring. To survive …

Tall fescue establishment and management in south west Victoria

M. C. Raeside, Michael Friend, R. Behrendt, A. R. Lawson et autres

Abstract Tall fescue ( Lolium arundinaceum syn. Festuca arundinacea Schreb.) is rarely used in the south west Victoria region of Australia, and little information is available on its suitability and management in this environment. Summer‐active varieties of tall fescue could potentially benefit …

Novel Cocksfoots for SE Australia: Establishment and production

S. G. Clark, R. A. Culvenor, Margaret Gardner, C. A. Harris et autres

Four new Cocksfoot (Dactylis glomerata) cultivars have been bred for areas of temperate Australia that have annual rainfall normally considered insufficient for the species. The new cultivars were bred from plants selected for persistence and production in areas with acidic, high aluminium …

Field evaluation of perennial grasses and herbs in southern Australia. 2. Persistence, root characteristics and summer activity

Zhongnan Nie, S. M. Miller, Geoff Moore, Belinda Hackney et autres

Field experiments were carried out at seven sites in southern Australia from 2002 to 2006 to measure changes in plant frequency, root characteristics and summer activity for a range of grass and herb species or cultivars. Annual rainfall during the experimental period …
