Agronomy

The BCG Research Team are undertaking trials across the Wimmera Mallee and are constantly on the look-out for timely, topical and technical information in the paddocks.

Agronomic practices are a vital part of farming systems. These are practices that farmers incorporate to improve soil quality, enhance water use efficiency, manage crops and improve the environment.

Durak Oats treated with PGR at BCG Main Research Site

BCG Oaten Hay Trial at Curyo trial evaluating the use of PGR Moddus®Evo @ 200mL/ha on lodging and hay quality.

We’ve seen a visible effect on height and maturity of Durack sown 5 May, PGR applied 10 August at GS32 (foreground).

BCG have sown Wintaroo, Brusher, Yallara, Mulgara, Koorabup, Carrolup, Durack and Bannister at the BCG Main Research Site to compare the hay yield and quality of different oat varieties across sowing times in the Southern Mallee.

Funding from Agrifutures has been allocated to observe whether a PGR application can reduce lodging in oats sown for export hay.


Effects of Deep Ripping on Pulse Root Structure

4 September 2020 - Kate Maddern

The images below show the effects that deep ripping has had on the root structure of pulses growing on ripped and unripped soil. The site at Netherby, hosted by RobCo, has two major soil constraints: non-wetting sandy top soil, and a hard setting clay pan at approximately 15-20cm deep. A section of the trial was kindly ripped by the site hosts prior to sowing to a depth of approximately 30cm with 65cm tyne spacings.

PBA Hallmark XT lentils grown on deep ripped soil (L) compared to unripped soil (R). Lentils sown on the 25th of May, dug up on the 31st of
Genesis 090 chickpeas grown on unripped soil (L) compared to ripped soil (R). Chickpeas sown on the 25th of May, dug up on the 31st of August

The trial will be taken through to harvest to measure yield and grain size, and will be reported in the 2020 BCG Season Research Results and presented at Trials Review Day in 2021. This trial was made possible thanks to BCG members, as this trial was funded through BCG memberships.


Gibberellic acid (GA) in Vetch

20 August 2020 - Brooke Bennett

GA (GALA @ 80ml/ha) applied on the 31st of July at Pyramid Hill. Visual colour and height differences 18 days post spray. Vetch sown on the 6th of May.

Vetch TOS at Pyramid Hill south site

20 August 2020 - Claire Browne

TOS1 was sown on May 4 and TOS 2 was sown on 26 May.

These photos were taken on 31 July and show the differences in 2 varieties between the two sowing times.

While only 21 days difference, the variance in growth is large. The maturity groups are as follow:

Timok: Mid
Morava: Late
Popany: Very late

When each variety reaches flowering hay cuts will be taken from each variety to determine total biomass from the different times of sowing.


BCG Main Field Site – Time of Sowing x Variety

Main Site – Curyo – TOS Canola Varities

24 July 2020 - James Murray

Hyola 350TT and ATR Bonito Canola at Curyo sown 31/3, 22/4, 5/5. The optimal start of flowering date for canola in Birchip is 26 July. Both varieties sown 22nd April will nail this optimal flowering date, the 31/3 sown ATR Bonito has also flowered close to this date. The quicker maturing Hyola 350TT has flowered slightly earlier when sown 31/3 however still within the acceptable range of 33 days within the optimum date (10/7-11/8). The 5th of May sown crops will both likely flower too late and miss this optimal flowering window.


Timok vetch sown 9th April, 22nd April, 5th May. Showing large vigour and biomass differences. Will be interesting to see implications for disease management and hay cut time as the season progresses.

Yellow tipped leaves in barley – Pyramid Hill

21 July 2020 - James Murray

Yellow tipping of leaves was observed in a number of barley varieties at Pyramid Hill, Spartacus CL pictured. This is characteristic of what this variety and some others closely related show at this time of year. Be sure to correctly diagnose any potential nutritional deficiencies or disease issues before addressing these, as it may just be leaf tipping. The crop will likely grow out of this as the season progresses. See an article form InterGrain from last year.


Blackleg upper canopy trial

27 May 2020 - Kelly Angel

Canola flower at Curyo

Photo taken at the main site yesterday. Hyola 350TT punching out its first flower, the rest of the plot is well and truly bolting.

This plant is part of a trial looking at upper canopy blackleg infection from different times of sowing, sown April 9… it’s just too early. 

Good example of the need to match phenology to sowing date – how many other examples of this will we see this year given the early rains?


Pyramid Hill Trials

Pyramid Hill TOS1 emerged and TOS2 being sown on 26 May.  GRDC Pulse agronomy trials and BCG trials


Keep an eye out for Mice

26 May 2020 - Tom Draffen

Reports indicate there are still plenty of mice around. Anecdotally later harvested barley paddocks along with pulse paddocks appear to be worse. Keep monitoring paddocks, as there are reports of paddocks that have been baited and still finding plenty of activity.
