" Soil Acidity and pH Management for Central West Farming Districts.. Central West Farming Systems (CWFS) has identified (Acid soil action initiative, 2000) that the growing incidence, in certain districts, of low pH in the surface (0-10cm) and subsoil (10-30 cm) as a long term trend will limit crop yield in particular districts of low rainfall areas... Current and future decision support tools regarding lime application developed for irrigation and high to safer medium rainfall production regions will not produce management change in marginal medium to low rainfall districts as they fail...
GRDC Taxonomy:
The communication has been important in identifying research priorities and particularly delivering in-field outcomes associated with the management of powdery mildew fungicide resistance in barley... The communication with stakeholders has been carried out in general by the laboratory scientists and while effective, it has not been particularly efficient... Following completion of the National Plant Pathology Review, the GRDC invited us to submit a four year-project focussed on communication of fungicide resistance management strategies to a level comparable with that available to stakeho...
The aim of the project is to overcome the barriers in growing two crops under irrigation in 52 weeks or less... Double cropping entails more than just growing a winter crop then following it with a summer crop... Core sites will be established to enable accurate and intensive investigation following identification of the most critical regional issues identified by the project steering committee, while taking into account relevant prior RD&E.Preliminary issues already identified in the GRDC Irrigation Regional Cropping Solutions (RCS) Network will form the starting point of the project, nam...

" Economics of closing the yield gap in the Northern Grains Region.. A third measure to help growers make decisions to improve yield will be benchmarks for water productivity, otherwise known as water use efficiency, for different soils and scenarios for each part of the Northern Region... Workshops will involve growers and advisers in discussion of yield targets and ways of closing the yield gaps, along with the economics of improvements and putting it all together to make the farm and region more profitable and productive...
GRDC Taxonomy:
This project 'A review of GRDC crop rotation, break crops and sequencing investments' fits within the Advancing Profitable Farming Systems theme... The projects aim is to thoroughly review the investment both past and current across all GRDC regions, into crop rotations, break crops and sequencing... A detailed report will be produced that provides recommendations for the investment planning into future crop rotation, breaks crops and sequencing projects...
Coordinating the improved management of soil acidity in Western Australia and the GRDCSouthern Region... The project will coordinate a national effort to effect a step change in the management of soil acidity in the Western and Southern GRDC regions... Existing and new information including data from lime trials, publications and recommendations will be used to develop or improve a collection of simple calculators which will enable growers to make informed decisions to ensure that they are confident about the management decisions they make including an understanding of the likely outcomes ...
GRDC Taxonomy:
The Grower Group Alliance was formed in 2002 by five grower groups with an overall objective of communicating and collaborating... In 2007, with the support of their member groups and the GRDC, the two groups merged into one project, delivering operational and resource efficiencies... The current Grower Group Alliance provides one network servicing all groups in WA regardless of size, one set of communications to network members, a united face for grower group representation and a wider network for grower groups, while being more streamlined for industry partners...
GRDC Taxonomy:
Sucking pests like aphids are an emerging problem in Australian grain crops due, in part, to the use of synthetic pesticides which suppress predator populations and encourage the development of insecticide resistance... A supplementary approach to the management of these pests is the use of naturally occurring fungal pathogens of these insects... The ultimate aim of this project is to develop a biopesticide for the management of sucking pests, including the delivery of information required in the successful registration of the product in Australia...
GRDC Taxonomy:
The system will use existing water-balance simulation models, online climate (BoM) and soils (e.g. APSOIL/SoilMapp) information and be informed by local rainfall and soil observations... Industry forums will be conducted and focus groups involving growers and advisors from each grain region will be engaged during development of the system to provide feedback and evaluation... Once the prototype system is developed, historical datasets and field trials undertaken on a range of soils and in each of the main grain-growing regions will be used to verify the accuracy of the system developed...
GRDC Taxonomy:
Unpredictable weather conditions at the time of flowering cause large yield fluctuations on a regular basis... Stabilising productivity of wheat crops in an unpredictable and changing environment requires wheat varieties that are more tolerant to abiotic stress conditions (terminal drought, heat, chilling and frost)... We have identified the genetic loci responsible for maintaining grain number in two wheat doubled haploid populations (Cranbrook x Halberd, Sundor x AUS30604) using hydroponics and osmotic stress as an alternative screening method and are currently evaluating drought toleran...
