Hyper Yielding Crops meeting – key points from 23 February meeting

Riverine Plains hosted Hyper Yielding Crops project meetings at Brocklesby and Rutherglen on Tuesday 23 February, 2021. Results from the Hyper Yielding Crops On-farm Focus Trials, as well as the results from the Hyper Yielding Crops technology centre at Wallendbeen were discussed, with presentations by Nick Poole and Tom Price (FAR Australia), Jon Midwood (TechCrop) and Kate Coffey (Riverine Plains).

More detailed results and information from the Hyper Yielding Crops field day are available by downloading the following presentations NSW HYC Grower meeting 23 Feb 2021 and 210223_HYC RP Innovation Groups

Key points from the On-farm Focus trials were;

Nitrogen trial, Howlong (Accroc wheat)

  • There were clear differences between the northern and southern parts of the paddock, based on the old fence line. The differences could be paddock history, soil type or past management or all of the above.
  • In the northern half of the paddock, there was a negative yield response to extra 100kg/ha urea (46kg N/ha) at GS30 in the strip trial. Yield decreased by 0.45t/ha and gross margin loss was $147/ha.
  • On the southern half of the paddock, the addition of 200kg/ha urea (92kgN/ha) at GS30 produced an extra 0.55t/ha, compared to the Nil urea at GS30 strip to the south. This gave break-even situation.
  • Grain protein (N content of the grain) of the highest yielding strip was only 8.3%.  With different N timings maybe the highest yielding treatment could have been even higher?

Fungicide trial, Culcairn (Trojan wheat)

  • Based on this trial, if stripe rust was left uncontrolled,  yield loss was up to 4.0t/ha.
  • Cogito at GS30, Prosaro at GS32 and Opus at GS39 gave the highest, significant (p<0.05), yield of 7.67t/ha. The additional gross margin from the application of fungicide was: $800/ha.
  • If farmers continue to grow susceptible varieties such as Trojan and Bennett, adding flutriafol on the fertilizer gives the grower significant improvement in levels of control. Fungicides will still be required at GS32 and GS39.

Nitrogen trial, Gerogery (HyTTec canola)

  • Based on this trial, an additional 80 kg/ha of urea at the yellow bud stage gave a significant (p=0.005) yield advantage over the overall paddock strategy. The gross margin of the additional applied nitrogen was $29/ha.
  • Increasing the rate of urea at yellow bud to 160 kg/ha urea didn’t increase yield significantly.
  • To optimize yield,  aim for a target flowering dry matter of 5t/ha. The trial reached this optimum amount of dry matter at flowering. Hybrids offer the potential for higher and more resilient yields over the open pollinated varieties.


Free Hands-on Precision Agriculture Training – Yarrawonga, March 1

23 February, 2021  

Word Count: 314 


 Registrations are now open for an introductory Hands-On Precision Agriculture (PA) Training workshop on Monday 1 March in Yarrawonga. 

 Adrian Roles, from JMAJ Consulting, a leading PA consultant and educator from Young in New South Wales, will facilitate the Riverine Plains and the Society of Precision Agriculture Australia (SPAA) workshop funded by Grains Research and Development Corporation (GRDC).  

This free, interactive workshop will provide growers with an overview of precision agriculture, and hands-on experience with a range of PA technologies and how they can be used to improve the productivity and profitability of their farm business. It will feature case studies from local farmers and PA experts,” Mr Roles said.  

 “Attendees will learn how to develop a basic PA plan, assembling a PA team, and identifying the tools and technologies they either have, or will need, to successfully implement PA on their farm,” Mr Roles finished.  

 Workshop sessions will focus on proven technologies and practices currently in use by growers and advisors including: 

  • how to identify variability (yield mapping, remote sensing, soil and pH mapping, in season monitoring) 
  • how to identify the key causes of yield and profit variability (including acidity/alkalinity, nutrient deficiencies, weed pressure, water logging etc.) 
  • techniques to address yield and profit variability (variable rate, in paddock blending) 
  • predictive analytics (yield forecasts, input management, pest and disease forecasts) 
  • mobile device, tablet and computer based integrative/farm management platforms. 
  • case studies from local farmer Adam Inchbold and PA experts. 

 A second, more advanced workshop will be held later in the year and will build upon the experience gained and the data collected during the 2021 growing season. 

 For more information please visit the Riverine Plains Inc website at riverineplains.org.au or contact Riverine Plains, on (03) 5744 1713. Registration is essential as attendancis limited to 20 people.  Register by email to Fiona Hart at info@riverineplains.org.au
