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.

Implementing Precion Agriculture in the Australian rice industry. (March 2014)

This Poster presented at the Rice field day at RRAPL in March 2014. The poster presents and overview of the current Precision Agriculture project in the Australian rice industry. It discuss the method and current focus on the project which includes the use and adaptation of EM31 and EM38, NIR, NDVI, water temp, depth, irrigation layout, yield.

Managment of drill sown rice (October 2012)


This fact sheet is a guideline for the management of drill sown rice. It is divided into sections and a brief overview is given. The fact sheets includes, site preparation, sowing time followed by Management at sowing with subheadings including seed placement, sowing rate, row spacing and fertilizer at sowing. The following section include herbicide application and irrigation management with a brief of 1st and second flushes. There is a section on in crop fertilisation, pre permanent water application, permanent water and Pi nitrogen.

Permanent beds in bays for sustainable cropping (2007)

This IREC Farmers Newsletter reports on the continuation of the permanent beds for sustainable cropping which has been running since 2000. The reports for 2005, 2006, and 2007 are included in this library.  The report covers 05/06 results, weed control, rice growth and yields, irrigation and fertilisers. This report concluded that high yields of wheat were achieved in 2005. This was seen on both raised beds and flat layouts – in a year without rainfall- induced water logging in winter or spring. It was also seen that the rice yields on both raised beds and flat treatments were excellent during an exceptional rice growing season. It was acknowledged that the rice yield from the bed systems is as high as that from conventional flat systems where rice is grown using permanent flooded conditions and deep water is applied during the early microspore stage.

The Efficacy of Rice as a Leaching Crop - Project No. 2105 (2005)

The concluding phase(s) of a rice rotation experiment presented the opportunity to assess the effect of consecutive crops of rice on the chemistry of the soil profile.  An experiment which aimed to determine the potential to use high salinity groundwater for the irrigation of the non-rice phases of a wheat - sub.clover - rice rotation, and then use rice, irrigated with low salinity channel water (<0.1 dS/m), as a leaching crop was undertaken.  The rotation included a single rice crop between each cycle of the application of saline groundwater.  Although soil salinity of most horizons under saline treatments could be reduced by leaching in the rice phase (single crop), this was not true for sodicity. Average rootzone sodicity remained elevated above control values at the end of each cycle and increased following successive cycles.
