"Results from the project suggest that trying to increase wheat protein with late foliar N application is unlikely to be a very effective management tool in areas where spring rainfall is highly erratic," he said... Although the late foliar application of N can deliver significant increases in protein, it is unlikely to deliver an economic benefit unless grain N recovery rates are high, untreated protein levels are close to a receival grade threshold and the premium between receival grades is at least $20/t," he said... "In terms of application, multiple low rate application in the 2014 trials did not appear to improve the response compared to the same rate applied in one application...

Varietal differences in yield loss with delayed harvest can be in excess of 1.5 t/ha... There was a large difference between the amount of height reduction measured at the two sites with the maximum height reduction being 7 cm at Spring Ridge in 2011 compared to 34 cm at Moree in 2012... The low protein of Commander has generally been an advantage to meet malt specifications over the past couple of seasons extremely low proteins have been achieved throughout the region (<9%) suggesting that yield may have been sacrificed at this level...

There was a large difference between the extent of height reduction measured at the two sites with the maximum height reduction being 7 cm at Spring Ridge in 2011 compared to 34 cm at Moree in 2012... Gairdner has been found in previous studies to achieve approximately 1-1.5% higher protein than Commander with the same N input, which was again the case at Moree and Bithramere in 2011... For the purposes of this paper yield and anthesis dates for 9 and 11 varieties for the wheat and barley TOS trials, respectively, are presented...

There are two series of trials that will be reported in this paper... The 2012-13 trials investigated interactions between N and sulphur at each site only the N responses will be reported ... Across the 3 seasons of trial work only one significant increase in grain yield was recorded in the 2005-07 seasons (Table 3)...

"Growers apply nitrogen at these late timings solely to increase grain-protein levels," says Richard Daniel, chief executive officer of NGA. ".. The project assessed the effect of nitrogen on protein accumulation, the likelihood of economic benefit, and whether there was an optimal method or timing for nitrogen application... The trials suggest that growers: plant more areas of grain legumes to supply nitrogen in a slower release organic form, which is also less prone to denitrification; match nitrogen inputs with water availability and crop-yield potential; avoid applying nitrogen before significant rainfall events that may lead to waterlogging and denitrification; and consider the overall cost of nitrogen application compared to the return on higher grain-protein prices...

Five strategies to manage nitrogen deficiency in Central Queensland.. Mr Conway says that due to the flooding in recent years, growers are being encouraged to introduce more grain legumes into their rotations to put nitrogen back into the soil... Growers are encouraged to talk to their local agronomists about smart fertilising programs, and to consult the GRDC handbook Managing legume and fertiliser N for northern grains cropping : www.grdc.com.au/GRDC-Booklet-ManagingFertiliserN..

While no differences in the lodging sensitivity of varieties to N application could be shown, Buloke and Hamelin have weaker straw than Baudin and Vlamingh... Subject to acceptance in international brewing markets, Buloke and Vlamingh have the potential to replace the current area sown to Baudin, Gairdner, Hamelin and Stirling... The Farmnotes, based on research in this project and from other GRDC funded projects, contain advice about the management needed to overcome the weaknesses in each variety...

For many the summer cropping rotation will include sorghum and maximising crop yield and profitability will be a key driver of all pre-plant and in-crop agronomic decisions... The research took in data from 12 sites across the northern region during 2012-2013 to determine the agronomic and economic responses of grain sorghum to varying levels of N nutrition... Sites where starting soil N was less than 70kg N/hectare were all responsive to N application...
