The comparisons represent the general farming system and evolution in management over the last 30 years of many progressive grain growing farms in low-rainfall regions of Australia... The largest increase to yield and water-use efficiency was achieved by improved summer weed management (Scenario 3)... A wheat variety with a long coleoptile gives a large yield increase in combination with the other management improvements (Scenario 6)...

With frost damage now estimated to be costing growers $360 million a year, the Australian National Frost Program (ANFP) is broadening its assault on the issue... Dr Juttner says methods varied across the country, so the results could not be compared... Dr Juttner says the method ANFP researchers have now developed involves staggered times of sowing, so that when a frost event hits they can tag individual heads of different wheat and barley varieties, at the same stage of development - in other words, they can compare the effect of frost on different cultivars at a synchronised developmental stage and compare like with like...

" Harnessing the Biological Potential of Australian Cropping Soils.. Titled 'Harnessing the biological potential of Australia's cropping soils', the Soil Biology initiative II (SBI-II; 2009-2014) is investing in research, development and extension (RDE) themes that build on the knowledge generated from a previous soil biology program (2002-2006) and from priorities identified at a GRDC workshop (Next Generation Soil Biology RDE)... An ongoing output will be the coordination of review workshops and reporting processes to ensure that adequate resourcing, integration and consistency measures are being applied across all projects and new opportunities are identified...

Summer rain adds to crop management options for season 2013.. Overall, the wheat yielded 4t/ha on average, which included the ungrazed LongReach Spitfire and EGA Gregory wheats... James hopes to investigate the allocation of contract labour more thoroughly in a bid to see if it can allow the family to capture more fully the benefits of any excess rainfall...

There is a need to improve N management in Australia's grain production systems, both for economic and environmental reasons... This project aims to develop a compendium (knowledge document) plus interactive excel-based decision support (DS) software ('NBudget') for improving knowledge and management of soil, fertiliser and legume N. The N management package is targeted at farmers and advisers... Making decisions about how much fertiliser N to apply to a particular paddock is set to be more challenging than usual after the wet 2010 season and early part of the 2010-11 summer fallow...

The stubble management decisions each of these growers made in 2010-2011 were unique to the individual and were influenced by the combination of experiences, cropping systems, agronomic and logistic challenges, and commitment to full stubble retention... The value of grazing crop stubbles to farm profitability was overestimated by the ME value of the intake the value of grazing crops cannot be predicted using energy intake from stubble... Finally the burning of stubbles also contributed to weed 26Australian Glyphosate Sustainability Working Group, Australian Herbicide Resistance Institute (2013), 9 Oct 2013...

Strategies to manage winter crop stubbles without reaching for the matches Conservation farming combines minimum or no tillage, full stubble retention and diverse crop rotations... From the work, it was postulated that when large volumes of stubble are spread, the chaff and straw interacts, increasing the overall bulk of material affected by air-drag... Using stubble treatments such as cabling, rolling and slashing result in up to 90 per cent control and the stubble is retained...
