Welcome to the February Rice Extension Newsletter. 

Welcome to the February Rice Extension Newsletter. The run in to harvest is an exciting time and weather conditions have been excellent for potential high yields as well as ground preparation for the next crop.

We have some great events coming up before harvest – it would be great to see you there.

  • New Website
  • Harvest maintenance
  • Reiziq is more synchronous than Amaroo
  • Desiccants - a tool for improving harvesting efficiency in lodged rice crops
  • An easy water budget
  • Spraying armyworm in the lead up to harvest – be aware of harvest withholding periods

A great message from @GribbleRC on Twitter – cleaning harvest gear is vital!

Rice varieties nowadays are more synchronous than the old Amaroo. This makes a difference to the way crops ripen, according to Peter Snell NSW DPI.

New varieties, especially Reiziq, will ripen more evenly and provide a more uniform harvest sample. This provides a higher quality paddy at milling, processing and cooking.

However, this means the grain dries more evenly in the field and grain moisture can get to low levels quickly - that will affect your whole grain yield appraisal. Keep an eye on the moisture.

The 2017 harvest presented many challenges due to seasonal conditions that triggered greater lodging than normal.

For a faster harvest, less stress on the operator, less wear on the harvester and timely harvest of other rice crops, some growers desiccated their crops with Reglone®. The industry has had limited experience with the use of desiccants so the Rice Extension team has developed a fact sheet including the experiences of three growers: Dessicants: a tool for improving harvesting efficiency in lodged rice crops.

In summary

  • Reglone® is registered for use as a desiccant on rice and can be used to increase harvesting efficiency in lodged crops - note abide by the 5 day harvest withholding period.
  • The rate of moisture decline is higher in warmer weather, so harvest crops that mature in warmer weather early in the season soon after the 5 day withholding period.
  • The whole grain yield of crops sprayed with Reglone® was similar to non-sprayed crops with some above average and some below average.
  • Spray when the grain is mature – when not more than 2 to 3% of the grain is still at the milky stage and the grain moisture content must be less than 25%.

Do you know how much water you will need to finish your rice crop?

How much water you will use depends on how much water is in the paddock now, the date you plan to drain the crop, and how much water is drained off the crop.

Use the tables in our fact sheet to calculate an estimate of how much more water you will need here.

For many rice crops only a small volume of water needs to be drained prior to harvest, however for later maturing crops or when a large rain event occurs prior to harvest the volume can be significant. Ideally all drainage water is contained on farm in re-use systems for irrigating other crops.

In some cases water will need to be drained off farm into irrigation district drainage infrastructure.

Murrumbidgee Irrigation, Coleambally Irrigation and Murray Irrigation operate under Environmental Protection Authority licences. This means that if compliance to licences is not adhered to strict penalties can be applied.

For all irrigation supply company regions water drained from rice fields will need to be held on farm for at least 28 days from the date of chemical application.

If you are in the Murrumbidgee Irrigation area the drainage rules can be found at: http://www.mirrigation.com.au/Customers/Contracts-Rules or call 02 6962 0200 for more information.

In the Murray Irrigation area of operation, landholders need approval prior to releasing water into the drainage system or back into the supply system. Murray Irrigation requires this information to manage its system. The relevant forms can be found at: http://www.murrayirrigation.com.au/customers/forms/general-forms/ or contact Customer Support on T. 1300 138 265 for more information.

Coleambally Irrigation requires that farmers have on farm re-use system storage capacity that is sufficient to contain any contaminated water for the duration of the with holding period. Their rules prohibit the release of contaminated water into their drainage system, and landowners in any doubt about releasing water should contact Coleambally Irrigation prior to releasing water into the drains. Coleambally Irrigation drainage rules can be found at; http://new.colyirr.com.au/Information/RulesPolicies.aspx or call 02 6954 4003 for more information.

To protect yourself and your communities it is strongly recommended that you contact your irrigation water supply company before draining rice water from your farm.

Be aware: drainage water can carry stem rot to new ground where rice may be grown in the future.

Stem rot occurs in very low levels across all regions in most years, for some reason the stem rot is severe in some years in isolated areas. Continuous rice cropping increases the chance of stem rot, especially if burning of stubble is poor between crops.

More information: Andrew Watson, Plant Pathologist at NSWDPI has completed a factsheet on stemrot:

While we are in the midst of the rice season, this Women in Rice event will focus on innovation and research involved in producing rice for a changing marketplace.

The free information and networking event will include a bus tour of Rice Research Australia Pty Ltd to meet the industry experts and talk about:

  • Developing new rice varieties
  • Producing seed
  • On farm impact on grain quality
  • Future technology for rice growing

Followed by lunch at the Old Coree homestead and a presentation from Shannon Cumberlidge from SunRice and Kari Cook from Riviana on 'Understanding your consumer'.

This event is for women who want to understand the rice industry better, are interested in innovation and research or just want to meet other great women in the industry. It doesn't matter how long they've been in the industry or how much they already know. We want to create an environment where women can share information, learn something new and ask whatever questions they like.

Blighty Recreation Reserve on Thursday 22nd Feb, commencing at 10.00 am.

Murray Local Land Services conducted a survey of 20 irrigated subclover pastures in the Finley, Deniliquin and Mathoura areas last spring. The survey indicated that there is a widespread problem with clover nodulation. Only 15% of pasture legumes had an adequate level of nodules on their roots. Less than 20% had the correct strain of Rhizobium present in the nodules. These two problems are undoubtedly reducing nitrogen production and pasture production.

Dr Sofie DeMeyer from Murdoch University, one of Australia’s leading experts on legume nodulation, will address these issues.

All irrigators are welcome to attend. Morning tea served from 9.30 am, the meeting will conclude no later than 12.30 pm.

Please RSVP for catering: John Fowler, Murray Local Land Services on M: 0427 079 138 or E: john.fowler@lls.nsw.gov.au
