Caption: The University of Western Australia Institute of Agriculture and School of Earth and Environment researcher, Dr Hossein Khabaz-Saberi, is part of a local research team funded by GRDC that is making breakthroughs in improving nitrogen-use efficiency in wheat and barley... Prof Rengel said a double-haploid wheat mapping population - created from lines differing in N-use efficiency - was phenotyped during the project, and this population offered promise in identifying Quantitative Trait Loci (QTL) associated with N-use efficiency... Prof Rengel said the research found 'vegetative growth' measures to be ineffective in-the-field predictors of N-use efficiency throughout the season, except potentially for barley at sites with relatively low soil fertility...

Despite flowering earlier, mustard did not yield better than canola in 2011.. The results show the importance of early growth up to flower bud appearance to the yield potential of canola and mustard as this helps develop the sink capacity (i.e. pod number)... This study of different canola and mustard cultivars showed the improvement in yield with added nitrogen...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... Delaying any action that has the potential to cease grain fill will see more seeds achieve their maximum size and improve yield... In summary there was no 'concerning' level of seed loss observed at any trial or timing, correlating well with the yield data...
