• the weed competitiveness of different varieties at different row spacing configurations, and
• the relative yields of the different varieties with the different herbicide applications and row spacing configurations.

To look at the impact of 2012 break crops on Rhizoctonia inoculum in 2013 and of crop management on disease expression in the 2013 cereal crop. 

To update the benefits of fluid delivery systems from previous research and assess the potential of fluid nutrients and disease control strategies in current farming systems.

To build on previous research by updating knowledge of the benefits, including disease control and nutrition, of fluid delivery systems.

To use NGS technology to identify a broader range of pathogens present in the diseased roots. 

To examine the issue of field mould in faba bean.

To determine if disease suppression against rhizoctonia is achievable in an upper EP environment on a grey highly calcareous soil using different rotations and cropping inputs.

To determine if disease suppression against rhizoctonia is achievable in a grey highly calcareous soil using alternative rotational systems and crop inputs in an upper EP environment and if soil microbial populations can be influenced by rotation and fertiliser inputs.

To determine if disease suppression against rhizoctonia is achievable in an upper EP environment on a grey highly calcareous soil. It also assessed whether soil microbial populations can be influenced by rotation and fertiliser inputs in this environment.

This was the second year of a three-year trial, funded by the South Australian Grains Industry Trust (SAGIT), to evaluate the nitrogen fixation capabilities of various legume species commonly grown on Kangaroo Island.

In this second year, the trial was set up to answer the following questions:

• Which of the four legume species had fixed the most nitrogen (N) in the 2016 season?
• How much N did these legume crops fix?
• How much of the N fixed by the legume was utilised by the following crop? Concurrently, how much N was lost through leaching or denitrification?

To investigate inter row sowing and no-till.

To assess growth (via top biomass at heading) and grain yield of diverse oat varieties (vs durum wheat check) under saline-sodic soil conditions, compared with "good soil" conditions at Turretfield.

To assess the impact of soil nutrition, current herbicides, adjuvants and rhizobial inoculants on nitrogen (N) fixation by medics under field conditions typical of the upper Eyre Peninsula. 

To quantify the economic benefit to farmers of:

• applying high application rates of phosphorus (P) on moderate buffering soils (phosphorus buffering index PBI) across a range of sites with different yield potentials, and
• comparing three-four common wheat and barley varieties to assess their Phosphorus Use Efficiency (PUE).

To investigate the effect of full stubble retention compared with other stubble management methods and seeding technologies

To investigate the effect of full stubble retention compared with other stubble management methods and seeding technologies.

To assess the impact of soil nutrition, current herbicides, adjuvants and rhizobial inoculants on N fixation by medics under field conditions typical of the upper Eyre Peninsula. 

The broad aim of this 3 year SAGIT funded project was to investigate if current management tools for medic based pastures, such as herbicides, fertilisers and rhizobial inoculants, are affecting N fixation by medic pastures under field conditions typical of the upper Eyre Peninsula.

This project aimed to explore different management strategies to overcome copper deficiency in cereals. The project compared the effectiveness of copper sulfate and copper chelate applied either as liquids banded at seeding or as a foliar spray. The project also evaluated the effect of different timings of application of the foliar sprays and their efficiency.
This project aimed to benefit local and South Australian farmers by establishing an independent best practice management guide for copper applications for the future.

To investigate the threshold temperatures to kill weed seeds, and the temperatures achieved when burning crop residues in various formats to faciliate weed seed control of problematic weeds in low rainfall cropping systems. 

To assess the new products with a range of application strategies and compared them to other management options (tillage, zinc, starter nitrogen, deep sowing, fluid fertiliser and late sowing) which can change the impact of rhizoctonia on crop production.

To maximise canola productivity through creating soil specific management strategies that improve canola yields, profitability and establishment in field trials on lower and upper Eyre Peninsula (EP). In 2014, ten separate trials were conducted as part of this project at Minnipa Agricultural Centre, and Piednippie on upper EP. Four trials will be reported in this article but only from Minnipa Ag Centre trials, as the Piednippie trial site was too variable.

To maximise canola productivity through creating soil specific management strategies that improve canola yields, profitability and establishment in field trials on Eyre Peninsula.

In 2015, seven separate trials were conducted as part of this project at Minnipa Agriculture Centre and Piednippie on upper Eyre Peninsula. Three trials will be reported in this article. Further trials were conducted on lower Eyre Peninsula and will be reported in the LEADA results booklet.
