Greg Bender, GRDC Program Consultant "Diverse" is a way to describe pastures: diverse uses in different farming enterprises and regions, and biodiversity of species including annual and perennial grasses, legumes, herbs and shrubs... Clearly pastures make a valuable contribution to the production of agricultural commodities, but the inherent diversity of pastures makes it difficult to estimate their total economic and environmental value to Australia... Ongoing support for research, development and extension (R,D&E) in pasture varieties, agronomy and management from federal and state governments, universities, CSIRO and rural R&D funding organisations is an essential part of the success of pastures...

" Agribusiness Crop Updates 2006 Analysis of a wheat-pasture rotation in the 330 annual rainfall zone using the STEP model Andrew Blake and Caroline Peek, Department of Agriculture, Geraldton mm.. KEYMESSAGES Self regenerating biserrula pastures grown in rotation with wheat were more profitable than volunteer pastures based on the assumption that the legume phase can lift wheat yields and improve grain quality... It was assumed that wheat grown in the first or second year after legume pasture would be higher in protein and attract the $10/tonne premium paid in the AH segregation...

Summer sowing hard-seeded annual pasture legumes, using seed harvested on-farm, has been a robust method of establishing pastures on Mike O'Hare's New South Wales property.. Ms Hackney says the high feed availability of all species, but particularly the biserrula, in autumn/winter is of substantial value to mixed-farming enterprises and has implications for increased nitrogen fixation for subsequent crops... Overall, lamb live-weight gains averaged 350 grams per head per day when measured over 56 days during spring 2014...

KEYMESSAGES Inoculating pasture legumes must be an ongoing process... The efficiencies of the products were continually evaluated for use in Western Australian agriculture by research at the Centre for Rhizobium Studies... Measurements included the percentage of plants nodulated, the amount of nodules on each plant and the strain of bacteria in each nodule, which was identified by fingerprint profiling using polymerase chain reaction (PCR) as described in Yates (2005)...

Summer-sown hard-seeded French serradella ( Ornithopus sativus ) varieties have potential to revolutionise the legume phase of crop rotations in Western Australia's medium and high-rainfall zones, according to researchers... They offer opportunities to: establish pastures cheaper, earlier and more reliably than traditional annual pasture legumes; fast-track the transition between crops and pastures; improve pasture biomass production; achieve good seed-set; achieve high N fixation in the first year of the pasture phase; and avoid interference with winter crop sowing at the season break...
