@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)

[James Manson @trialsofJManson]

@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

@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 :)

[James Manson @trialsofJManson]

@becsta1984 Thanks for your comment :) FYI I am doing a PhD overview talk at Dimboola on August 6th and Katamatite on August 14th

[James Manson @trialsofJManson]

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!

@becsta1984 Sucks to be the under-researched crop 🤦‍♂️

[James Manson @trialsofJManson]

@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 😝

[James Manson @trialsofJManson]

@becsta1984 Given the seasonal variability in Australia, do you get the same result twice for agronomy with any crop?

[James Manson @trialsofJManson]

@originalstinger If they don't like winter they'll try again later :)

[James Manson @trialsofJManson]

We know from theory that cereal crops should attain 95% light interception by flag leaf emergence to maximise their potential. In my post-doctoral fellowship funded by @theGRDC and @CSIRO, I'll validate, revise and/or qualify this target for southern Australia.

[James Manson @trialsofJManson]

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

Phillip Porter at Livyn Seeds can (very affordably) place your seeds in dissolvable tape at the desired spacing.

@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

[James Manson @trialsofJManson]

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.

🎤 Wimmera faba bean growers – don’t miss out!

Join @trialsofJManson at March discussion groups as he unpacks ‘From Flower to Pod to Yield: What’s Holding Your Beans Back?’ 🌱

Hey look what I found on Kangaroo Island

[James Manson @trialsofJManson]

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)?

[James Manson @trialsofJManson]

@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.

[James Manson @trialsofJManson]

@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?

[FAR Australia @far_australia]

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
