To investigate amelioration of subsoil acidity through topdressing higher rates of lime and combining lime with gypsum.

To develop lucerne cultivars, specifically for the southern Australian cropping districts, that are compatible with existing farming systems as well as being productive and persistent. The breeding program is focusing on improving tolerance to acidic soils, persistent grazing and establishment with companion crops

To determine the susceptibility of new chickpea varieties and fungicide treatment against Ascochyta blight.

To determine if the livestock carrying capacity of pastures in the eastern Wheatbelt of Western Australia, including those on mildly saline soil, can be increased by replacing native ryegrass with the Safeguard variety of ryegrass.

To evaluate Diuron as a broadleaf weed killer pre sowing of lupins and to evaluate some mixing partners to improve the control of grass weeds.

To evaluate a range of nutrients on lupin yield and protein.

To compare agronomic factors on seven lupin varieties for yield and grain protein.

Assess the yield of wide (18 inch) versus narrow (9 inch) lupin rows.

To evaluate the effect on wheat yield and quality of applying ameliorants at depth on a Wodjil soil (Graveyard Trial).

To compare returns for wheat and barley in their different segregations to determine the most profitable return for farmers.

To demonstrate the tolerance of WALAN2141 to Metribuzin.

To evaluate the quality and yield of Carnamah wheat in response to a range of in-furrow fungicide applications.

To evaluate specially formulated biodegradable soil wetters ability to improve crop establishment and yields in hydrophobic (non-wetting) soils.

To investigate the response of wheat to phosphorus fertiliser grown on an alkaline crumbly clay soil type.

To assess the relative production of a range of commonly grown pasture species.

To test the effect of ploughing in stubble prior to seeding.

To establish the potential to increase wheat yield on acid sands at East Maya.

To test the effect of four levels of management inputs on grain yield, quality and profitability.

To quantify the benefits pre-furrowing after pasture in a low rainfall area. Prefurrowing runs a point through dry soil to help rainfall entry.

To fine-tune the fertiliser requirement of yielding zones in different paddocks.

To determine the susceptibility of new chickpea varieties and fungicide treatment against Ascochyta Blight. However, due to herbicide damage the chickpeas weren’t harvested, therefore only Lentils and Fenugreek are discussed in this trial.

To determine whether the seed inoculant, Pr-70, is economical on acid sands at Jibberding. The inoculant will be used in conjunction with increasing rates of phosphorus to determine the most profitable return for farmers in the region.

To investigate benefits of soil amendments on acid soil for wheat and triticale.
