ANZAC day traditionally marks the start of seeding in many areas and GRDC has released a timely set of NVT trial results.


Grain growers and advisers across Australia are being provided with a suite of unique new resources to inform crop variety decision-making.

The GRDC has released its inaugural series of National Variety Trials (NVT) Harvest Reports, which provide the very latest independent varietal information about yield, quality and disease ratings from the extensive NVT program.

GRDC NVT Senior Manager, Sean Coffey, says the 16 regional Harvest Reports contain the past five years of results - including 2019 - for every NVT trial held across Australia.

He says the information is presented at a local site level to support grower and adviser decision-making about variety selection.

"The reports are an exciting new addition to the stable of NVT resources, offering growers and advisers another layer of important information to help them with crop variety choice," Mr Coffey says.

"We hope these publications will be seen as useful decision-support tools, underpinning selection of varieties that offer the best fit for individual farming systems and growing environments."

Relevance to the regions

The Harvest Reports reports are designed to complement - not replace - the GRDC-supported state-based Sowing Guides, which are published prior to harvest.

Northern cropping region Harvest Reports are for:

  • Central New South Wales;
  • Northern NSW;
  • Southern NSW;
  • Central Queensland; and
  • Southern Queensland.

Southern Harvest Reports cover:

  • Eyre Peninsula South Australia;
  • Mid North and Yorke Peninsula SA;
  • Mallee SA and Victoria;
  • Western Victoria, Lower South-East SA and Tasmania;
  • Northern Victoria; and
  • Wimmera Victoria and Upper South-East SA.

The five western region Harvest Reports are for:

  • Albany Port Zone;
  • Geraldton Port Zone;
  • Kwinana West Port Zone;
  • Esperance Port Zone; and
  • Kwinana East Port Zone.

Evaluation extension

The NVT program evaluates more than 550 near-release or released crop varieties each year.

It provides independent, consistent, timely and robust comparative data about yield performance, quality and disease resistance ratings of commercially available grain varieties.

"NVT represents a huge logistical undertaking, evaluating varieties for the 10 major crop types - wheat, barley, canola, chickpea, faba bean, field pea, lentil, lupin, oat and sorghum - in trials across the country," Mr Coffey says.

He says the system is conducted to a set of predetermined protocols, and trials are sown and managed to reflect local best practices, such as:

  • sowing time;
  • fertiliser application;
  • weed management;
  • pest and disease control; and
  • fungicide application.

"The largest coordinated field trial network of its kind in the world, NVT is a 100 per cent GRDC investment that is fully administered by the GRDC on behalf of Australian grain growers and the Australian Government," Mr Coffey says.

"Single site results from successful trials in 2019 were finalised earlier this year and this data has fed into multi-year, multi-environment trial (MET) variety performance analysis.

"These multi-year, rolling datasets for all crops and growing regions provide the most valuable information to support decision-making around what to sow each year."

Yield data valuable

The new Harvest Reports feature the very latest information from the 2019 harvest that has been built into the rolling datasets. This includes results and analysis from last season and from sites across the nation.

To support growers and advisers, the GRDC has produced instructional videos on 'How to interpret NVT data (long-term yield results) using the NVT website' and 'How to navigate NVT's website'.

Mr Coffey says planning for the NVT program for 2020 is now well underway, with the number of trials across the nation expected to be around 650.

In the meantime, growers and advisers are encouraged to keep an eye on their email inbox - as the GRDC is distributing electronic links to the new Harvest Reports as they are published.

To ensure they are receiving the latest NVT information from their regions, growers and advisers can nominate their Harvest Report preferences via the GRDC subscription centre.
