To demonstrate Sakura’s commercial fit for efficacy on barley grass and yield compared to the grower’s standard treatment in wheat.

To look at the following soil amelioration treatments on water repellent pale sand:

• no amendment (nil);
• 3t/ha limesand; and
• 150 t/ha clay rich (31% clay) subsoil spread with a multi-spreader

To assess the second year impact of mouldboard ploughing on wetting up of water repellent soil and on lupin establishment and yield.

To compare two methods for the establishment of pasture legumes (i) summer sowing where dormant hard-seed is drill sown into the paddock after the crop is harvested; and (ii) traditional sowing where scarified seed is drill sown after the break of the season and knockdown weed control.

To compare two methods for the establishment of pasture legumes (i) summer sowing where dormant hard-seed is drill sown into the paddock after the crop is harvested; and (ii) traditional sowing where scarified seed is drill sown after the break of the season and knockdown weed control.

To evaluate effectiveness of ‘summer sowing’ hard-seeded serradella pod into established perennial grass pastures.

To evaluate which combination of an early bromoxynil based herbicide and follow up post-emergent herbicide will provide the best weed control and Return on investment (ROI) in a system approach to wild radish control in cereals.

To evaluate the performance of annual crops when pasture cropped over different perennial species.  

To complement the existing research and development occurring on the upper Eyre Peninsula while keeping in line with district agronomic practices.

GRDC has funded a programme to address this issue and one of the projects within this programme is developing an improved understanding and implementation of management practices for brassica and pulse crops, pastures and other options to reduce the risk of crop failure and improve whole farm profitability in low rainfall south-east Australia.

The purpose of the trial was to compare growth rates and dry matter production of alternative pastures with traditional medic pastures
