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.

 

GRDC SPRAY APPLICATION WORKSHOPS AT DOOKIE AND RUTHERGLEN

Riverine Plains Inc are hosting two Grains Research & Development Corporation (GRDC) Spray Application Workshops on 13 and 14 September, 2018.  The half-day workshops will be conducted by Bill Gordon, from Bill Gordon Consulting and are designed to assist farmers get the most from their spray equipment.

Bill is a consultant who has delivered a number of GRDC funded projects related to application technology and drift management to the Australian agricultural industry.

Through a combination of practical demonstration and ‘sit-down’ training, Bill will provide up-to-date information on nozzle selection, droplet behaviour, drift reduction, weather for spraying and inversion risk.  He will also discuss the need for different setups depending on the type of spray job at hand, recent changes to regulation and herbicide resistance.

Two workshops will be held in the Riverine Plains region:

Dookie – Thursday 13 September

1pm – 4pm

The University of Melbourne – Dookie Campus, 940 Dookie-Nalinga Road, Dookie

Rutherglen – Friday 14 September

9am – 12noon, lunch provided

Agriculture Victoria, 124 Chiltern Valley Road, Rutherglen

There is no charge to attend the workshops.  These workshops are funded by the Grains Research and Development Corporation (GRDC) as part of the Practical and applied workshops and communications to promote key messages and resources to maximise the effectiveness of spray applications in the southern region project.

Bookings are essential as workshops are strictly limited to 25 attendees.

New publication: Soil Carbon In Cropping Systems

Riverine Plains Inc has just released Soil carbon in cropping systems, which is a new publication designed to help the region’s farmers better understand soil carbon and the role it plays in crop production systems.

The report summarises the key findings from the Riverine Plains Inc managed project Increased soil carbon by accelerated humus formation from crop residues (2012-2015), which specifically aimed to evaluate the potential for soil carbon to be increased by adding stubble residues and nutrients to soils during the summer fallow period.

While the final results from the research trials conducted at Rutherglen, Tocumwal and Culcairn were largely inconclusive when it came to building soil carbon levels from stubble (due to the short-term nature of the project), many other important practical, scientific and economic lessons were learnt along the way. Soil carbon in cropping systems brings together these key lessons, along with farmer case studies and soil science to help local farmers better understand their soil resource.

Soil Carbon in Cropping Systems was funded by the Sustainable Agriculture Victoria — Fast Tracking Innovation Initiative, made possible with the support of the Foundation for Rural and Regional Renewal (FRRR) together with the William Buckland Foundation.

Increased soil carbon by accelerated humus formation from crop residues (2012-2015) was funded through the Australian Government’s Department of Agriculture Action on the Ground program with support from project partners: Murray Local Land Services, the North East Catchment Management Authority and the Victorian Irrigated Cropping Council.
