 An international research collaboration with CIMMYT (International Maize and Wheat Improvement Center, Mexico) has developed new wheat germplasm carrying Karnal bunt resistance genes. These will be made available 
to Australian breeders for variety development. As a prerequisite, this study was carried out to determine what penalties could affect yield or its components due to incorporating Karnal bunt resistance.

This experiment aimed to evaluate agronomic management options that enhance the yield potential on this specific soil type.

The objectives were to:

1. reduce nitrous oxide emissions from dryland grains cropping.

2. improve nitrogen use efficiency.

3. validate and develop process-based biogeochemistry models.

4. simulate net greenhouse gas emission under current and projected future climate scenarios. 

This experiment is beginning to characterise the reaction of Australian barley varieties at the seedling stage to scald isolates collected from southern NSW. It complements the adult plant screening process. 

In this series of experiments, we have quantified the extent of yield loss displayed in a number of commonly grown winter cereal varieties in southern New South Wales across four years.
 

The aim of this work is to increase the sources of multi-disease resistant germplasm available for barley variety improvement in Australia. This is being achieved by screening and identifying possible sources of resistance to barley scald and other diseases from the centres of origin of barley cultivation. 

This research identified the plant traits most likely to determine differences in external critical phosphorus (P) requirements (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of pasture legume species. Understanding trait differences that affect critical P requirements of pasture legumes is important in providing confidence around field differences in external critical P requirement.

The study determined whether genetic differences in tolerance can be idenified in field grown wheat exposed to natural heat events at the early reproductive stage of development.

The aim of this experiment was to develop disease response curves indicating potential yield losses for a selection of varieties that represent various resistance categories for YLS.

This experiment examined the effect of yellow leaf spot (YLS) on yield in three wheat varieties of differing resistance in southern NSW.

To improve our understanding of the interaction between the pathogen life cycle, the host crop and environmental conditions with the view to developing a disease prediction model for industry to use.

To determine agronomic management practices that increase grain yield potential while also minimising the risk of fungal diseases.

To evaluate the efficacy of pre-emergent herbicides against grass weeds in wheat.

To evaluate the efficacy of pre-emergent herbicides against grass weeds in chickpea.

This experiment is one in a series of nitrogen experiments aimed at establishing variety responses to different nitrogen application rates and timings.

To investigate the interaction between early sowing and row spacing and variety in first wheat crops under full stubble retention.

 To answer some of these questions and provide data for use in modelling the trial outcomes over long-term climatic data sets. 

To access the impact of wheat varieties on Pratylenchus thornei build-up and soil distribution profiles.

To study the influence of seed size on the yield of the faba bean variety PBA Nasma.

To compare grain yield responses with variations in three maize hybrids and six nitrogen rates under raised-bed flood irrigation at Breeza on the Liverpool Plains.

To report on the nitrous oxide (N2O) emission results from the 2014–15 grain sorghum trials, which aimed to optimise both nitrogen (N) rate and fertiliser N release to benefit crop production and reduce N2O emissions.

To evaluate the impact of groundcover quantity on fallow water efficiency

This research aimed to determine the external critical phosphorus (P) requirement (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of a range of pasture legume species under field conditions. This information can be used as a benchmark for soil testing and soil P fertility management on farms.

To evaluate the effect of sowing date on phenology and grain yield of 12 canola varieties ranging from long to short season phenology types. 

To compare the growth, development and yield of current commercial faba bean varieties and advanced breeding lines at two sowing times at June reefs in Southern NSW.

To determine seed or planting treatments impact on thrips in commercial scale trials.

To evaluate the performance of recently released wheat varieties in response to various times of sowing.

Some districts in NSW and Victoria are known to frequently develop Sclerotinia stem rot. The purpose of conducting the petal survey was to identify if there are significant differences in the level of petal infestation between districts where the disease develops frequently, compared with those districts where the disease develops once every few years. This information will indicate what influences disease development, background inoculum levels or environmental conditions, or both. 

To see whether green manure a viable management option (in terms of maintenance of ground cover and other agronomic benefits) as we know that terminating cover crops will result in 100% seed set control providing that the crop is effectively killed at an appropriate time.

To test the hypothesis that over time in controlled traffic farming systems the repeated uneven spreading of header residue back over the tram track width would result in changed soil conditions that would ultimately lead to different “management zones” along the tram track.
