In 2008, earthy, musty off-flavours were detected in peanuts in north Queensland, which led to over $1 million of product downgrades... The actinomycetes produce volatile compounds that contaminate the stored nuts, and cause the musty, earthy off-flavours... Contamination of peanuts can occur in the field during the growing season and also during post-harvest storage and handling...

Validations on plot trials produced an R 2 of 0.97 between simulated and measured plant N (g N m -2 )... Fitzgerald et al. 2010 reported a correlation with an R 2 = 0.97 between predicted and measured total plant N (g N m -2 ) based on relating the CCCI to the Canopy Nitrogen Index (CNI) - an index that relates biomass to plant N. This relationship was validated with additional plot level data from Australia and Italy, resulting in an R 2 of 0.97 of predicted with measured plant N (g N m -2 ) and an RMSE of 0.2 g N m -2 as reported in Cammarano et al. 2011b... In the short term, there is a need for a workshop to fully identify the knowledge gaps, and develop a plan for research leading to new capabilities and deliverables to growers and consultants...

The project will deliver validated indices derived from remote sensing that can spatially measure and map canopy-level crop nitrogen (N) status within rainfed wheat systems... Remote sensing (spectral and thermal) combined with crop models can provide maps showing chronic and acute water stress areas that can guide N management strategies within the context of potential for response to targeted N inputs... Results from trials in Australia and Italy show ability to relate remote sensing measurements at the plot scale to plant N, based on remote sensing of the canopy and biomass measurements...

GRDC Grains Research Update Coonabarabran, February 2014 most sites achieved those returns within 2 crop seasons after deep P application may at least partly reflect the string of wetter seasonal conditions in recent years, although the results from Jandowae, Capella and Gindie all included dry seasons in at least one of the crops followed... Overall, the performance of the barley grain only varieties showed they are capable of producing around 6 t/ha of dry matter and still yielding between 2.7 and 3.4 t/ha of grain... Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)...
