In northern Victoria, Australia, perennial pastures for the dairy industry have historically been based on perennial ryegrass. However, perennial ryegrass does not perform well under high summer temperatures and water stress. We investigated irrigati

Improvement in nutritive characteristics resulting from breeding perennial ryegrass (PRG) cultivars used in Australia from the 1970s to the present day was quantified in a grazed field experiment in south-western Victoria. The experiment was sown in

Soil is known to be both a source and a sink for methane (CH4), while animal wastes can be a source. In experiments primarily designed to measure nitrous oxide emissions from the application of dairy cow urine, dung and pond sludge to pasture, CH4 em

Nitrous oxide (N2O) from excreta deposited by grazing ruminants is a major source of greenhouse gas emissions in Australia. Experiments to measure N2O emissions from dairy cow dung, urine and pond sludge applied to pasture, and the effectiveness of t

Knowledge of the components of the water balance – evaporation, transpiration and deep drainage – would be beneficial for targeting productivity improvements for irrigated forages in northern Victoria. We aimed to estimate these components using

Nitrous oxide emissions from flood-irrigated pastures grazed for dairy production were measured over 2 years using micrometeorological techniques. Turbulent atmospheric transfer coefficients derived from fluxes of sensible heat and momentum were used

Tall fescue (Festuca arundinacea (Schreb) Darbysh.) has the potential to become a useful component of irrigated dairy pastures in northern Victoria owing to its high dry matter (DM) production compared with perennial ryegrass. However, tall fescue is

Lucerne (Medicago sativa L.) has the potential to be grown widely under water-limiting conditions in the dairy region of northern Victoria and southern New South Wales, Australia, possibly because of its greater water productivity and because irrigat

Lucerne (Medicago sativa) has not been a significant part of the feedbase of the Murray-Dairy Region of Australia. However, under future climate regimes, which are indicating an overall decline in rainfall as well as water available for irrigation of
