@jtelferoz @ipaddockapps @JasonBrand @SC_Catt (also, lodging and height have decreased with 40 years of Australian faba breeding, so our tall crops are doing better these days than they used to)

@jtelferoz @ipaddockapps @JasonBrand it would be interesting to know what they do in europe. There's just a lot of nodes to hit with pgrs over the growing season. I think the best pgr would be a genetic solution, something I've discussed with @SC_Catt
English
I'm sure I saw growth regulators used routinely on beans in France, any EU or UK followers able to comment?
Barry Haskins@agrobaz
@brodenholland It would be nice to have a registered pgr for them. Tall beans on irrigation = lower yield 👉 disease + lodged harvest. On dryland it seems to be all about the finish. That’s a cracker broden 👍👏

@becsta1984 @jdwb84v8 I have observed that plot border rows set pods sooner (or they start growing quicker) than the central rows. A couple of weeks later you can't tell the difference. Might be worth some follow up checks on these lentils?
Light penetration is always interesting, watch this space :)
English
@jdwb84v8 Yep we see it clearly too in our fabas. I was thinking about it again recently after reading this article. @trialsofJManson has done some good work on fabas. I find them much more variable than lentils!

The relationship between #FabaBeans flowers & yield isn’t straightforward, says @CSIRO researcher Dr @trialsofJManson He shared his research at recent discussions in the Victorian Wimmera region ▶️ bit.ly/3HU80BN
English
From personal experience biomass doesn’t always translate to yield in our lentils. I think light interception drives some of that. Pdk sown EW, lentils on S side of wheel track podded, lentils on N side not much yet. Extra sun from the N hitting those plants w/o shading =pods
English
@becsta1984 Thanks for your comment :) FYI I am doing a PhD overview talk at Dimboola on August 6th and Katamatite on August 14th
English
@trialsofJManson Very true, Thankyou for the work you are doing on them as it is appreciated 👍 on our irrigation the fabas drive so much of our canola and cereal yields. Despite their erratic yields, we wouldn’t have a profitable or sustainable rotation without them 🌱
English
New (open-access) paper! I tried to figure out how to talk about pod-set in faba bean properly.
Key takeaway: Interactions between pods are agronomically irrelevant except after stress that kills flowers/pods. Focus on crop growth from flowering!
doi.org/10.1093/jxb/er…
English
@trialsofJManson Agreed, but I feel I can usually pinpoint what’s driving that variability in my other crops, fabas are the real wildcard
English
@LikePulseCrops Thanks! A shame I didn't come across this work earlier, but I couldn't focus much on hormones. I hope my paper can help sub-plant-focussed people link their findings to the field in ways that make sense to us field-focused people. Or at least give them someone to argue with 😝

@becsta1984 Given the seasonal variability in Australia, do you get the same result twice for agronomy with any crop?
English
@trialsofJManson Is that a way of saying fabas just do what they want really and you never get the same result twice even when you follow the same agronomy recipe? 🤔😂
English
@originalstinger If they don't like winter they'll try again later :)

One for the trial perfectionists! Precision planting without a small-plot precision seeder 🤤

@jtelferoz @GRDCSouth @JasonBrand @MichaelMoodie @matthew_sparke @ag_eyre I'm not promising, but I hope to do some short videos (in my 'spare time') and post online

@GRDCSouth @trialsofJManson @JasonBrand @MichaelMoodie @matthew_sparke Look forward to seeing this kind of approach/material available on EP sometime @ag_eyre :) #eyrebeans

Excited to unpack my PhD findings with growers! I aim to clarify what faba bean is doing so that we can make it do what we want it to do better. I'll also aim to use better sentences than that one.

We love the jacarandas in Adelaide. I love the opportunity to show how nearly all flowering plants overproduce and cull flowers, not just faba bean 😉🤓

@brodenholland @TrentAn94382106 2/2
I think a question is whether dividing biomass up into lots of heads and seeds is like slicing a pie into too many, small pieces, or is it worse than that (bad partitioning)?
English
@brodenholland @TrentAn94382106 Lots of growth from booting to flowering should maximise grain number and yield, but if you introduce disease and lodging then the story could change.

350 heads a m2, definitely letting the wheat do it's thing. Big heads fat seeds, less bulk.
Scepter, 50kg seeding rate, 7.5 inch spacings, 450kg urea, 250ml gsr, 530 YTD, est 6.7t/ha ish.
English
@brodenholland @TrentAn94382106 Hey Broden, am I correct that when you say ‘too many heads’ you mean you get predictably smaller grains in some or all seasons?
English
@TrentAn94382106 Talk with your agro obviously but here coz of our soils and growing season anymore we just end up with north of 450 heads and it's to many

Great turnout at our South Australia Crop Technology Centre field day today. Morning sessions provided some great insights into the canola and bean trials. Thanks to guest speakers Dr Angela van de Wouw of @UniMelb and James Manson from @UniofAdelaide for joining us to share their expertise. @Pooley_Nick_FAR @darcydww2 @Daniel_in_Ag @AaronVague @Blooming_fields @GRDCSouth @theGRDC @MacKillopGroup
