The objective of this trial is to demonstrate that growing canola (with effective weed control options) followed by a high value legume (with higher economic value) can lead to an effective and profitable double break crop sequence. The contribution of an early sowing date versus a traditional sowing date to increase the profitability of these crops will also be evaluated.

This project will determine the economic value of growing canola followed by a high value legume, and the impact of this rotation on the grain yield and profitability of a cereal crop in the first year following the double break crop sequence.

The intention is to observe how such treatments impact yield and grain quality of irrigated barley.

To increase irrigated wheat yields with well-timed applications of foliar sprays as well as pre seeding applications of micronutrients.

To assess the strategic use of nitrogen in the form of urea totarget 10t/ha spring wheat yield under irrigation.

To investigate the potential for response to P rates above 15 kg/ha.

To investigate the economic return of spraying fungicide for spot type net blotch in barley in the eastern wheatbelt.

To determine the effect of common district nutrition packages in Merredin on crown rot index (incidence x severity) of wheat and barley varieties.

To determine if chickpea respond to applied nitrogen.

To determine if lentil responds to applied nitrogen.

We aim to demonstrate the effectiveness of using clean seed and seed applied fungicide to minimise the amount of Ascochyta in a chickpea crop, and to demonstrate the effectiveness of early season foliar fungicides to keep disease levels at bay.

To demonstrate the effectiveness of liquid surfactants and related application methods at seeding on crop performance on non-wetting soils with differing stubble loads and types in the Albany, Esperance and Kwinana West port zones.

To explore the variation of PUE among varieties of wheat across a range of seasons in order to provide farmers with better knowledge of their current varieties.

Maize is not commonly grown in Tasmania. This demonstration was to see what varieties would work in the local environment

We plan to demonstrate a range both peat and granular inoculant options for chickpeas, placement of these products with seed vs. with fertiliser, and the interactions of these products with seed applied fungicide.

To identify key ingredients of agronomic packages that deliver high yielding wheat crops with good quality in the Parndana environment.

• To demonstrate to the biodiesel industry the potential of Kangaroo Island canola as a promising feedstock. 
• To test the potential of genetics to improve canola production and the canola agronomy trial tested the potential of management to improve production.

To identify key ingredients of agronomic packages that deliver high yielding canola crops with high oil contents in the Parndana environment.

Growers in this environment have been hesitant to graze canola due to the long season traditional grazing varieties and the risk of heat stress in late spring/ early summer. The hope was that a series 5 spring variety would mature earlier and require one less irrigation in spring. The growers were accepting that a yield decrease would occur however it would save them an irrigation.

To promote early vigour to improve biomass and yield partitioning in chickpea.

To promote early vigour to improve biomass and yield partitioning in faba bean.

To promote early vigour to improve biomass and yield partitioning in lentil

This field trial was undertaken at Westmere in Victoria, a high rainfall environment, to investigate factorial combinations of sowing time, seed rate and herbicides on the management of annual ryegrass in barley.

We aim to determine if faba beans in higher rainfall zone respond to high rates of phosphorus, in-crop nitrogen and/or a complete/intensive nutritional and disease management package.

Demonstrate the effectiveness of different fungicide timing options on chocolate spot management and evaluate a new spray decision support tool.
This trial was a collaboration of the Crop Protection and Grain Science groups within DPIRD.

To discuss nitrogen inputs from pasture and patterns of release for crops.

This trial was located at Cunderdin in the grainbelt of Western Australia and investigated combinations of canola variety (Hybrid or open pollinated), crop row spacing (25 or 50cm) and canola seeding rate (20, 35 or 50 plants/m2) on wild radish (WR) competitiveness and seed production.

To asses the effect on crop yield of multiple rates and application strategies of micronutrient fertilizers in soils deficient in the target micronutrients (copper, zinc, manganese, boron and molybdenum)

This field trial at Gladstone was undertaken to investigate factorial combinations of wheat seed rate and herbicides on the management of annual ryegrass.

To investigate the response to changing the nitrogen rate and changing the time of application. Canola yield and oil will be measured and RR hybrids will be compared with open-pollinated TT types (OP TT).

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.

The aim of this research was to benchmark yield potential across a range of growing environments in the NGR over two consecutive seasons, and to quantify the effect genotype (G), management (M) and environment (E) had on yield.

To investigate factorial combinations of sowing time, seed rate and herbicides on the management of brome grass in faba beans.

These two experiments aimed to evaluate a range of herbicides with different modes of action on prickly lettuce control, and to evaluate if a ‘double-knockdown’ technique is needed to effectively control mature prickly lettuce.

To investigate establishment, crop phenology, days to flowering, flowering duration, and grain yield responses of commercially available pulse and legume varieties.

 To investigate whether competitiveness can be increased in chickpea and faba bean to reduce sowthistle biomass and seed production, and how this affects crop yield.
