Rice plant population (2017)

The rice plant population target is 200 to 300 plants/m2 in southeast Australia

  • Difficult establishment conditions can often reduce plant populations to low levels

  • Growers needed plant population limits based on economics to known when to continue with a crop or re-sowing was needed

  • This research investigated plant populations for aerial and drill sown rice and determined appropriate population limits

  • We also investigated row spacings for drill sown rice

Rice phenology (March 2015)

This Poster presented at the Rice field day at RRAPL in March 2015 by Brian Dunn from NSW DPI Yanco. The poster presents information on phenology of rice and the variability that occurs as a result of varieties, sowing, nitrogen rate and timing. The understanding of the phenology assist agronomic management and the this can lead to improvements of yield and quality.

Rice Extension on the New Grower Services Web Portal for SunRice (2014)

Access to the RICE EXTENSION TAB will be for all growers who will have a login, and also to Advisors, non-SunRice growers, researchers who will need to be set up with a login password access. This group are an important link for future extension to be successful.

Improving rice water use efficiency - Direct Drilling of rice and Precision Farming (June 2014)


Water use efficiency is a driving factor for the Australian rice industry. Australian rice farmers grow rice in one of the driest continents in the world, achieving some of the world’s highest yields per hectare and water use efficiency per kilogram produced (Dunn & Pal Singh, 2013). In recent years, the availability of water for agricultural production has been reduced significantly as a result of government policy. Australian rice farmers are also under constant scrutiny to justify their water usage, so need to develop new technologies and practices. Historically Australia is one of the few countries to establish a rice crop by flying rice seed into a flooded bay. The majority of the countries visited establish their crops by drilling seed into the soil and establish by flushing. In Australia, this technique could be more broadly adopted with significant savings in water use and input costs.
