(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)

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

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!

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.

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 😉🤓

This is apparently a protein-protein interaction diagram... Published in 2024 by Elsevier's Journal of Agriculture and Food Research. doi.org/10.1016/j.jafr.2024.…

ABARES data suggests that Aussie faba yields increased at 0.8 % per year from 1990s. Because we found lower genetic yield gain than 0.8%, it comes from better systems, better management, and then synergies with the easier to grow varieties. 🙌🙌 for growers and agronomists too!

A (2/2): Yield hasn't increased across the collection, and seed number went down as size went up. To get more seeds, with same or bigger size, we need to increase harvest index and/or biomass somehow. Tackling GxE is also going to be important.

A (1/2): If faba bean was a pavlova, then new varieties are cut into bigger slices (bigger seeds, if you ignore the broadbeans), stand up better (lodging resistance) and don't go mouldy (disease resistance). That's a better pavlova! And it was improved on a limited budget! 1/2

Q: How has breeding changed Australian faba bean varieties?
A: See our new paper! (and comments below) sciencedirect.com/science/ar…

Also not sure now if Kenton meant hot drying conditions at sowing/emergence or at the end of the season 🤷😅

Do you suspect benefits from deeper root growth won't compensate for extra shoot biomass and soil water depletion in a tough finish?
