Cereal scientist with DPIRD involved in barley and oat agronomy, physiology & pre-breeding research in Western Australia.

Essentially, what this body of @DPIRDbroadacre research suggests (relative to Bannister): 1. Goldie's N fertiliser package is similar, 2. Koala's N fertiliser package is also similar, but avoid > 100 kg N/ha, and 3. Minnie may benefit from slightly more N.
@DPIRDbroadacre has been evaluating the performance of three new milling oat varieties—Goldie, Koala, and Minnie—to see if they respond differently to fertiliser applied N. The link contains my observations from several years of trialling in WA. https://t.co/dkObHguo7M

That time of the year - a matrix of crop maturities appears as the barley/oat crop dries & awaits harvest. Bigger differences in maturity in our oat material than in our barley material, although long-spring barley is still green compared to commercial springs. @DPIRDbroadacre

Our @DPIRDbroadacre Greenhills oat site was seeded on opening rains on 06 May. 205 mm rain for the growing season. Varieties are differing in their phenology. Plots with 3 cuts are at 3 or more weeks after Z49, with 2 cuts have passed Z49, and with 1 cut haven't reached Z49 yet.

Are you going to OATSPO? Hamid & I will be there. Hamid will chat about our @DPIRDbroadacre study funded by POP, unlocking the yield vault of oats. There is a selection of oats from around the world to look at. I'll talk about Goldie at the @ConsultAg site. Bring your questions.

14WAS NDVI done at the Corrigin POP-funded oat yield trial. 108 oat varieties from Australian & beyond. Another ripper trial - thanks to @kalyx_australia for seeding & managing this site. @DPIRDbroadacre @InterGrain1

Another POP funded oat yield trial expanding our knowledge of oat yield pathways - this time at Narrogin - 14 weeks since seeding. @DPIRDbroadacre @InterGrain1

Barley plots with flag leaves appearing or out at the @DPIRDbroadacre site at Popanyinning-E looking a treat given the rainfall to date. 13 weeks since seeding. Assessing the next generation of ‘malt’ varieties.

Checking growth at the POP oat grain yield trial at Holt Rock - 15 weeks since emergence - looking great @DPIRDbroadacre @InterGrain1

Here are the results from this evaluation of facultative winter barleys from Oregon. They behaved more like true winter (Cassiopee) than what we call facultative barley (Urambie). Back to the drawing board. There may be some value in the mild winter types, though.
A little project on the side in 2023. Evaluating facultative winter barley germplasm from Oregon, USA (brought in through quarantine) to see if they have the right flowering genes that could fill the spring - winter phenology gap that exists in barley. Seeds planted 05 April.

Like barley - N lowers test wt & decreases plumpness. The impact on test wt was larger in oats. For every extra 50 kg N/ha applied, the test wt decreased by 1.4 kg/hL in Bannister & 1.1 kg/hL in Goldie compared to only 0.2 kg/hL in Maximus CL. Goldie is plumper than Bannister.
@BlakelyPaynter What is the N doing to the quality of the oats in those trials?

Someone asked me whether oats for grain respond the same way to N as barley—the answer is NO. In my experience, barley gains more grain yield with N application than oats. Implications - don't over-fertilise your grain oats. They don't need as much N as your barley.

It has been at least 6 weeks since wet seeding or a germinating rain at several more of my trial sites. Oats-only sown by @kalyx_australia: Corrigin & Narrogin (POP funded with @InterGrain1). Barley + oats sown by @DPIRDbroadacre: Greenhills & Popanyinning (DPIRD & POP funded).

Barley phenology trials powering along at Northam. Mundah, Rosalind, Spinnaker & Stirling all surpassed awn peep with 05 April sowing. All reps of Combat, Compass, RGT Planet & 4 unreleased lines will be done next week. Five sowing dates in the ground with last on 03 July.

Six weeks since germination for the Holt Rock & Wongan Hills Processed Oat Partnership (POP) @DPIRDbroadacre & @InterGrain1 oat trials. Early biomass scored by NDVI. Researching options for the next yield gain in milling oats.

Last of my @DPIRDbroadacre barley & oat management trials now sown (dry unfortunately) at Yerecoin. Others sites at Wongan Hills, Greenhills & Popanyinning all emerging on recent rains or with irrigation at Merredin. Pulling apart the latest genetics for our sowing guide.

The third barley/oat sowing date is now in the ground, with TOS1 sown on 05 April 2024 & TOS2 sown on 17 April 2024. 30 barley + 20 oat entries at Northam & Katanning. All supporting @DPIRDbroadacre "FlowerPower" tool - https://t.co/H5N4WOOC3x

All our @DPIRDbroadacre phenology data is found here - https://t.co/H5N4WOOC3x. Pick a commodity, choose an environment, and compare relevant varieties for sowing dates from early April to early July. In the case of barley we provide data for over 40 varieties.
@davidbmoody03 @TressWalmsley @BlakelyPaynter @agrobaz @InterGrain1 I don’t suppose Commodus or Compass was tested?

Exciting times ahead @HiroshiKubota2. Love to hear more about your proposed R&D program.
.@barley_research announces GrowBarley today at its symposium. It's the first barley specific agronomy program launched in Canada! Program lead Hiroshi Kubota talks about the important partnerships making it possible. @AlbertaGrains @SaskBarley @mb_cropalliance @feist_gina

I’ll be posting grain yield and quality data collected by @DPIRDbroadacre and through @GRDC_NVT on the relative performance of 13008-18 soon. We have also assessed it for export hay.
🌾The first classification has been made under our new National Oat Variety Classification Framework! Our Oat Varietal Classification Technical Committee has classified @InterGrain1 oat variety 13008-18 as a milling oat. Congrats @InterGrain! 🎉 👉 https://t.co/8guVLYNDFl

Certainly has good global adaptation, but under Western Australian conditions, the yield of RGT Planet is poor compared to other barley options at sites which yield below 3t/ha. Be interesting to see RGT Planet compared to Australian developed cultivars in the same experiments.
Interesting RGT Planet has drought resilience. Is that why it has been so widely adopted. Wonder where it gets the character from? Does the translocation play a role?
