    Abstract

    After preliminary observations and discussions with a farmer focus group near Wagga Wagga, a range of experimental subterranean clover (Trifolium subterraneum) pastures were generated through the use of various agronomic treatments, among them seeding rate and grass management treatments. These pastures were monitored while they were grazed over two years (1995 and 1996), using several parameters applicable to grazed pastures (seed/seedling population, ground cover, botanical composition, growth and biomass). The biomass and pasture growth parameters measured in the two field experiments were used to calibrate the GrassGro model, which was then used to estimate production targets for growth, biomass and N fixation using historic climatic data for Wagga Wagga, Lockhart, Condobolin and Tamworth. A benchmarking protocol for monitoring the performance of annual ley pastures based on subterranean clover is proposed and discussed.
