To condcut a barley variety trial.

This trial is the second year of the trial series comparing the performance and response of two breeding lines (03198-18, named Kowari , and 06204-16, named Bilby ) and two benchmark varieties (Carrolup and Williams ) to changes in nitrogen and plant density in medium rainfall environments. This research builds on the trials conducted at Holt Rock in 2014-2016.

This experiment, which was part of a larger project based at Tamworth (BLG106), was conducted to determine the effect on chickpea and lentil crop development and grain yield from varying amounts of cereal surface residue (mimicking stubble load) and the resulting lower temperatures.

To evaluate in-crop options for Tribulus spp. control.

To address the problem of subsoil acidification, a long-term field experiment was established in 2016. The objectives were to:
• manage subsurface soil acidity through innovative amelioration methods that will increase productivity, profitability and sustainability
• study soil processes, such as changes in soil chemical, physical and biological properties over the long term.

To evaluate the impact of soil disturbance on soil water capture and subsequent crop production.

To evaluate the impact of nitrogen application in Mungbean.

A range of organic amendments have been tested to assess their effectiveness on ameliorating soil acidity in the field. The crop yield was monitored over three years from 2018 to 2020.

To evaluate efficacy of chickpea desiccation options.

To evaluate the impact of harvest management on chickpea yield and harvest losses.

To evaluate strategies for selective spray top management of wild oats in chickpea.

To evaluate the impact of soil levelling on pre-emergent control of wild oats in chickpea.

The objectives of this project are to quantify the size and efficiency of response to mid-row banded nitrogen in irrigation systems within the southern Riverina of Australia. This will include the assessment of the effect of mid-row banded N on growth, yield and apparent nitrogen recovery efficiency (ANRE), of wheat as compared to the current best-practice method of topdressing at GS31 and the control.

Another key objective of this project is to assess the loss of banded nitrogen during waterlogging events to determine if denitrification losses are reduced in banded nitrogen and compared to topdressed nitrogen and the control.

To screen seed treatments for pest and disease management in mungbean.

To evaluate the impact of nitrogen application in Mungbean.

To screen fertiliser and plant growth regulators for biomass management and yield of chickpea.

Can systems performance be improved by modifying farming systems in the northern grains region? Specifically, what impact do crop species and crop sequences have on soil- and stubble-borne pathogens?

Can systems performance be improved by modifying farming systems in thenorthern grains region? What are the impacts of crops and crop sequences on soil water accumulation and use?

To evaluate the impact of sowing depth, method, plant population and sowing time on chickpea production.

To evaluate options for Tribulus control in sorghum.

To test the optimum sowing time for long season wheat cultivars uisng three target sowing dates.

To evaluate efficacy of chickpea desiccation options.

To evaluate the impact of harvest management on chickpea yield and harvest losses.

To screen fertiliser and plant growth regulators for biomass management and yield of chickpea.

To evaluate the impact of planter type, sowing depth and plant population on chickpea production.

Can systems performance be improved by modifying farming systems in the northern grains region? | In Goondiwindi: (i) What are the trends that are expected in our farming systems? and (ii) How will these changes impact on the performance and status of our farming systems?

To evaluate in-crop options for Tribulus spp. control.

Farming systems projects funded by the Grains Research and Development Corporation (GRDC) are assessing ways to improve the use of our total rainfall, with the aim of achieving 80% of the water and nitrogen-limited yield potential in our cropping systems.

To evaluate double knock timing and options for button grass control.

To evaluate double knock timing and options for button grass control.

This project is gathering data from these trial sites to ascertain whether a one-off application of either P, K or sulfur (S) that is placed in these deeper, more depleted layers can provide a grain yield benefit and whether that benefit can be maintained over several years.

To evaluate the impact of soil levelling on pre-emergent control of wild oats in chickpea.

To investigate the impact of long term controlled traffic.

To evaluate the impact of N rate, timing and method of application in Mungbean.

This project is gathering data from these trial sites to ascertain whether an application of P or K placed as a band in the subsurface profile can provide a grain yield benefit and whether that benefit (response) can be maintained over several years.

This project will test the ability of sorghum to germinate and withstand cold temperatures during early growth stages in order to reduce
heat stress during flowering and grain fill.

This experiment has attempted to use rainfall timing (imitated by overhead irrigation) to mitigate the negative weather impacts on
dry matter production both before and after flowering in an early and late summer TOS. A wide gap between TOS was deliberately
used to create the largest contrast in weather conditions that the crop would experience and then monitor how the plant’s physiological
development changes in relation to changing soil water conditions.

What are the long-term impacts on systems performance (e.g. productivity, profitability and soil health) when six strategically different 'farming systems' are applied to one geographic location over a five year period?

In 2018, field experiments were conducted across ten sites in the northern grains region in Central and Southern Queensland, and
northern, central and southern New South Wales to determine optimal grain yield potential of wheat genotypes.

To evaluate the efficacy of Chickpea desiccation options.
