Extension in the rice industry A review of the development, delivery and prioritisation of extension in the Australian rice industry - Link (January 2014)


This RIRDC report  presents the results and recommendations from the review thatwas undertaken as a RIRDC funded project of the extension arrangement that were in place in 2012/13. The report is to inform RIRDC, state and commonwealth government and industry agencies and organisations and individuals which have responsibilities or interests in, extension provision. The project was designed to review current rice extension arrangements at the time and those of other industry in an attempt to develop and advise and create recommendations for the future for Rice extensions against a background of extension theory.

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.

Sequential herbicide programs in delayed permanent water rice (March 2014)

This Poster presented by Malcolm Taylor at the Rice field day at RRAPL in March 2014. The Poster presents results from 2013/14 season of experiment on Sequential herbicide programs in delayed permanent water in rice. The conclusion presented in drill sown rice was increasing Stomp to 2.5l/ha plus Magister to 0.l/ha will improve barnyard grass control. It is important to note that crop safety can be compromised if extra stress on rice seedling establishment occurs. It also concluded that an alternative to group A herbicide the use for late barnyard grass germination was a mixture of Ordram and Stam with addition of Saturn if you used prior to permanent inundation in drill sown rice.

Mid-season Draining of Rice (March 2014)

This Poster presented by John Fowler at the 2014 Rice field day at RRAPL held in March 2014. The poster presents result and images of mid season draining. Midseason draining of rice is the practice of completely drying out rice bays in December, originally to reduce the impact of physiological sterility (“parrot beaking”).  Over three years nine farmer demonstrations indicated that two thirds of the crops gained an average yield increase of 18% by mid-season draining, the remainder had no yield impact. The practice is being adopted in the central and western Murray Valley.

Rice Crop protection guide (August 2012)

This is a twenty eight page Primefact guide by the NSW DPI to be used as a guide for weed and pest management of a rice crop. It is divided into sections that the cover pesticide selections and use, planting back guidelines, intergrated weed management. The next section is the guidelines for spraying pesticides onto rice crops, herbicide resistance management for weed control in rice. Following on from this the multiple programs displayed in tables for drill sown herbicide use, aerial sown herbicide programs that are divided into pre sowing. This section is followed by post sowing pre emergence, then early post emergence, guides to rotating herbicides and herbicide resistance. The guide then covers the insects, snails and earthworms and gives guidelines to manage such pests.

New water productivity targets for each rice growing valley. (2008)

This IREC Farmers newsletter is presenting the new water productivity targets for each rice growing valley. Using the rice check information from 1999-2007 it was established that the valleys had differenct water productivities. Therefore the new water productivity targets for 2008 were established for individual valleys based on yield, irrigation water use and rainfall records from Ricecheck since 1999. The articles outlines these targets and informs the reader to contact DPI for further information.

Extension for improving rice yields and water use efficiently 2004-2007 - Link (January 2008)


This RIRDC report is presenting the results of the project Extension for improving rice yields and water use efficiently 2004-2007. The report is targeted at farmers, retail agronomists and ancillary extension providers who have contact or supply information to rice farmers. The project aimed to increase yields and water use efficiency by 5% by improving adoption of better farm practices for each of the four irrigation valleys: Eastern Murray Valley (EMV), Western Murray Valley (WMV), Coleambally Irrigation Area (CIA) and the Murrumbidgee Irrigation Area (MIA). The method undertaken was a baseline data compiled from the average of three to five years prior to the commencement of the project. This was then compared to the harvest season average of SunRice yields and yields selected varitites, WUE and check adoption in each year from 2005-2007. The key findings were  
Average rice yield for the five years (2000-2004) preceding the project was 8.94t/ha. The average yield for the three years of this project was 8.9t/ha, hence yield remained the same. 2004/05 saw severe cold damage and the affected the average as a result of reduced yields in to 6.8t/ha. The 2005/06 and 2006/07 seasons yielded well at 10.0 t/ha and 9.9t/ha respectively. The poor 2004/05 season affected the water use efficiency for the project dropped slightly because of the very low yielding 2004/05 season and drought affected high water use 2006/07 season. WUE was 0.61, 0.8 and 0.7 t/ML respectively for the 2005, 2006 and 2007 harvest seasons. The average WUE of 0.7t/ML was 8% lower than the average for the previous five years.
