GRDC Hyper Yielding Crop focus-farm trials for the Riverine Plains

A new, four-year project is set to examine the yield potential of different varieties grown under various agronomic packages as part of a Grains Research and Development Corporation (GRDC) investment into hyper-yielding cereal crops.

Following on from the success of Hyper Yielding Cereals project in Tasmania, the Hyper Yielding Crops project has recently commenced on a national scale, with GRDC Centre of Excellence trial sites established in Victoria, Tasmania, South Australia, NSW, and Western Australia.

A Centre of Excellence has been established at Wallendbeen (near Cootamundra), NSW, with the research site chosen because it had a water-limited yield potential of 10 t/ha for cereals and 5 t/ha for canola.

Riverine Plains Inc has also worked alongside lead organization, FAR Australia, to establish three focus farm sites in southern NSW in support of the Wallendbeen Centre, with a canola site established at Gerogery and wheat sites established at Culcairn and Howlong.

Grower involvement is a major focus of the project, and Riverine Plains Innovation Groups are being established to link local growers with the focus farm paddock trials at Gerogery, Culcairn and Howlong.

The 2020 focus-farm paddock trials will look at nitrogen and fungicides, while future focus-farm paddock trials will be based on ideas arising from the local Innovation Groups, as well as from growers visiting the Centre of Excellence.

Riverine Plains Inc are also seeking ten paddocks from across the region to be nominated for the 2020 Hyper Yielding Crop Awards. The Award will benchmark agronomic aspects of individual wheat crops, with participating growers to receive an agronomic benchmarking report comparing that paddock to all others entered, both regionally and nationally.

The project combines the expertise of several farming groups, including Riverine Plains Inc, with FAR Australia, SARDI, Brill Ag, CSIRO, DPIRD, TechCrop and CeRDI.

This project will ultimately provide an opportunity to unlock yield potentials by providing a greater understanding of the possible constraints and the agronomic practices required to achieve potential yields in a given season.

Riverine Plains Inc are currently taking expressions of interest from growers interested in joining the Innovation Group, as well as from those farmers interested in being involved in the Hyper Yielding Crop Awards.

Integrated Harrington Seed Destructor Demonstration, Culcairn

The GRDC have invested in the Harvest Weed Seed Control in the Southern Region project (SFS00032 led by Southern Farming Systems), which is investigating the impact of different harvest weed management techniques on ryegrass weed seed banks.

As part of the project, Riverine Plains Inc, together with Farmlink, are holding an Integrated Harrington Seed Destructor (iHSD) day at Sherwyn Rd, Culcairn (Eastern end) on Wednesday 20th December commencing at 10.00am.

The iHSD is a mill that is fitted to a combine harvester to process the chaff fraction of harvest waste, with the mechanical action of the mills acting to destroy the weed seeds.

For the demonstration, Graham Kotzur will use a harvester fitted with an iHSD fitted to harvest canola, and will talk about the pros and cons of using the machine.

Kate Coffey will also speak briefly about the Riverine Plains Inc trial work evaluating the impact of harvest height, chaff removal and harvest timing on weed seed banks.

For further information download the iHSD demonstration day flyer or contact Kate Coffey, Riverine Plains Inc on (03) 5744 1713.

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.
