The research has made a significant contribution to our understanding of the mechanisms underlying these traits, identified novel strategies for further or more rapid improvements, and provides a solid foundation for both further research and better management of defects that result in downgrading of quality prior to harvest.. Annual screening of advanced lines from Australian breeding programs suggests little improvement in sprouting resistance despite breeders having had access to resistant germplasm and quantitative trait loci (QTL) information for a considerable period... Our work in Brachypodium presents a novel opportunity to use an undomesticated wild grass to identify novel sources of high dormancy germplasm...

It was proposed that DRB be isolated and evaluated against ARG. Successful organisms were then to be applied in high numbers and assessed in field situations... Until the mode of action of these bacteria is clearly defined and/or a rapid isolation and assessment protocol (perhaps with the aid of gene technology) identified, this project needs to be shelved... It was proposed that DRB be isolated and evaluated for annual ryegrass - with the aim of inhibiting seed set and subsequent annual ryegrass toxicity reduction...

Identify where the benefits of fluid fertilisers are likely to be significant, in terms of climate, soil type and cropping system... The conclusion is that while there does not appear to be any yield advantage associated with using Flexi-N through the boom, as opposed to urea topdressed prior to sowing, there does appear to be an advantage when it is banded... The freight was approximately $40/tonne, compared to solid fertiliser delivered bulk, which is approximately $20/tonne...

Overall, soil CEC and SOC content was greatest in the 0.2 and 0.2-2 m fraction, indicating that size, and probably type, of SOM influenced CEC... Kaiser et al. (2003) found that soils with a high content of black carbon showed increased sorption ability compared with plant- and microbial-derived SOM... Addition of organic amendments can increase P availability to plants by decreasing the P adsorption capacity of soils...

Lastly the strain is selected for its ability to survive in the soil between seasons... Let's consider if there is a need for inoculation of the crop with free-living N2-fixing organisms... The production of cluster roots and release of organic acids is extremely energy expensive; the plants strategy is to acquire P at any cost (Lynch and Ho 2005)...
